Answer:
a) P(8) = 0.1395
b) P(at most three) = 0.0423684
c) P(X > 8) = 0.41
Step-by-step explanation:
Data provided in the question:
Mean, μ = 8
Now,
Probability that the number of oil tankers on any given day is
a) exactly eight
using Poisson distribution
we have
P(x) = [tex]\frac{\mu^xe^{-\mu}}{x!}[/tex]
for x = 8
P(8) = [tex]\frac{8^8e^{-8}}{8!}[/tex]
or
P(8) = [tex]\frac{16777216\times e^{-8}}{40320}[/tex]
or
P(8) = 0.1395
b) at most three
i.e P(0) + P(1) + P(2) + P(3)
thus,
P(0) = [tex]\frac{8^0e^{-8}}{0!}[/tex] = 0.0003354
P(1) = [tex]\frac{8^1e^{-8}}{1!}[/tex] = 0.002683
P(2) = [tex]\frac{8^2e^{-8}}{2!}[/tex] = 0.01073
P(3) = [tex]\frac{8^3e^{-8}}{3!}[/tex] = 0.02862
⇒ P(at most three) = 0.0003354 + 0.002683 + 0.01073 + 0.02862
= 0.0423684
c) more than eight.
P(X > 8) = 1 - P(X ≤ 8)
Now,
P(0) = [tex]\frac{8^0e^{-8}}{0!}[/tex] = 0.0003354
P(1) = [tex]\frac{8^1e^{-8}}{1!}[/tex] = 0.002683
P(2) = [tex]\frac{8^2e^{-8}}{2!}[/tex] = 0.01073
P(3) = [tex]\frac{8^3e^{-8}}{3!}[/tex] = 0.02862
P(4) = [tex]\frac{8^4e^{-8}}{4!}[/tex] = 0.05725
P(5) = [tex]\frac{8^5e^{-8}}{5!}[/tex] = 0.091603
P(6) = [tex]\frac{8^6e^{-8}}{6!}[/tex] = 0.1221
P(7) = [tex]\frac{8^7e^{-8}}{7!}[/tex] = 0.13958
P(8) = [tex]\frac{8^8e^{-8}}{8!}[/tex] = 0.13758
Thus,
P(X > 8) = 1 - [ 0.0003354 + 0.002683 + 0.01073 + 0.02862 + 0.05725 + 0.091603 + 0.1221 + 0.13958 + 0.13758 ]
P(X > 8) = 1 - 0.5904814
or
P(X > 8) = 0.41

A customer wants rhombus-shaped tiles for his countertops. The height is 3 inches and the length of each side is 6.5 inches. What is the area of each tile?
Answer:
Area of each tile = 19.5 inches^2
Step-by-step explanation:
Rhombus:-
A rhombus is a type of quadrilateral whose opposite sides are parallel and equal.Also, the opposite angles of a rhombus are equal and the diagonal intersect each other perpendicularly.
To find the area of a rhombus when the measures of its height and side length are given, use the formula
A = Base X height
Area of a rhombus = 6.5 X 3
A = 19.5 inches^2
The area of each rhombus-shaped tile is 19.5 square inches for the given dimensions. Thus, each tile has an area of 19.5 square inches.
To find the area of a rhombus, you can use the formula
⇒ Area = base × height
In this case, the height is given as 3 inches and the length of each side is 6.5 inches, but the length of the sides is not needed, as we are working with the base and height directly.
So, the area can be calculated as follows:
Identify the base and height:⇒ Base = 6.5 inches
⇒ Height = 3 inches.
Use the formula for the area of a rhombus:⇒ Area = base × height.
Calculate:⇒ Area = 6.5 inches × 3 inches
= 19.5 square inches.
Therefore, the area of each rhombus-shaped tile is 19.5 square inches.

Suppose x is directly proportional to y but inversely proportional to z. If x =3 when y = 6 and z =4, then what is z when y=3?
When y = 3, the value of z is 2.
Since x is directly proportional to y and inversely proportional to z, we can write this relationship as:
[tex]x = k \frac{y}{z}[/tex]
where k is a constant of proportionality.
We are given the values x = 3, y = 6, and z = 4. Let's use these values to find k.
[tex]3 = k \frac{6}{4}[/tex]
Simplifying this, we get:
[tex]3 = k \cdot 1.5[/tex]
Solving for k:
[tex]k = \frac{3}{1.5} = 2[/tex]
Now we know the constant k. We can use it to find z when y = 3.
We know the relationship:
[tex]x = 2 \frac{y}{z}[/tex]
We need to find z when x = 3 and y = 3.
[tex]3 = 2 \frac{3}{z}[/tex]
Rearranging to solve for z:
[tex]3 = 6 \div z[/tex]
[tex]z = 2[/tex]

What is the total cost of a $720 ipad that is on sale at 15% off if the local sales tax is 6%
Answer:
$828
Step-by-step explanation:
15% = 0.15
0.15 x 720 = 108
total cost = $720 + $108 = $828
Final answer:
To find the total cost of an iPad that is on sale at 15% off with a 6% sales tax, calculate the discount, subtract it from the original price, determine the sales tax, and add it to the discounted price.
Explanation:
To find the total cost of the iPad:
Calculate the discount: $720 * 15% = $108 discount
Subtract the discount from the original price: $720 - $108 = $612
Calculate the sales tax: $612 * 6% = $36.72
Add the sales tax to the discounted price: $612 + $36.72 = $648.72
The population of Bigville increased from 387,480 to 571,533 in the last 7 years. During the same time period, Smallville increased its population by 53.67%. Compare the towns to determine which is growing at the greatest rate and by what factor? (round to nearest hundredth)
Answer:
Smallville is growing at a greater rate
Step-by-step explanation:
use the formula for percentage increase to find what percentage the population of Bigville increased.
(Increase ÷ original number) * 100 = % of increase
increase = 571,533 - 387,480 = 184,053
(184,053 ÷ 387,480) * 100 = 47.5
Bigville percent of increase is 47.5%
Smallville percent of increase is 53.67%
since, smallville has a bigger percentage, it is growing at the greater rate

Thomas had 12 juice boxes he gave some to his sisters he now has more rhan 5 left.Which inequality can be used to find j the number of juice boxes thomas gave to his sisters?
Answer:
J < T - 5
Step-by-step explanation:
T = The number of juice boxes Thomas had
J = The number of juice boxes Thomas gave to his sisters
Thomas had 12 juice boxes
T = 12
He gave some to his sisters he now has more than 5 left.
T - J > 5
-J > 5 - T
J < -5 + T
J < T - 5
To determine the number of juice boxes Thomas gave to his sisters, the inequality 12 - j > 5 is used, which simplifies to j < 7, indicating that he gave away fewer than 7 juice boxes.
To find j, the number of juice boxes Thomas gave to his sisters, we start with the total number he had initially, which is 12. We know that he gave away some juice boxes and still has more than 5 left. If we let j represent the number of juice boxes given to his sisters, then 12 - j > 5 would be the inequality that can be used to determine j.
Since Thomas has more than 5 left, but we don't know the exact number, we use the inequality to represent the situation. Therefore, if we solve the inequality, subtracting 5 from both sides, we get j < 7. This means that Thomas gave away fewer than 7 juice boxes to his sisters because he had more than 5 remaining.
A truck skids for a distance of 25\,\text m25m25, start text, m, end text with the road pushing on its tires with force of 1500\,\text N1500N1500, start text, N, end text as its brakes are applied.
The truck, experiencing a force of 1500 N, skids a distance of 25 meters, resulting in a change in kinetic energy of 37,500 J. Now, let's break down the concept of kinetic energy and the given data:
Definition of Kinetic Energy:
Kinetic energy, in physics, is the energy possessed by a moving object.
It represents the effort required to accelerate an object of a specific mass from rest to a particular velocity.
The body retains its kinetic energy even with slight speed variations, maintaining the energy acquired during acceleration.
Kinetic Energy Conservation:
When the body decelerates from its current velocity to a state of rest, the same amount of energy is expended.
Formal Definition:
Kinetic energy is formally described as any quantity exhibiting a gradient with respect to time in the Lagrangian of a system.
Given Data:
Force (F) = 1500 N
Distance (d) = 25 m
Calculation of Change in Kinetic Energy:
Utilize the formula for change in kinetic energy: ΔK.E = F × d
Substitute the values: ΔK.E = 1500 × 25
This results in ΔK.E = 37,500 J.
Therefore, the observed change in kinetic energy for the truck, moving a distance of 25 meters with a force of 1500 N, is precisely 37,500 J.

A motorboat left a harbor and traveled to an island at an average rate of 10 knots. The average speed on the return trip was 10 knots. If the total trip took 4.0 hours, how far is the harbor from the island?
The distance between the harbor and the island is 20 nautical miles.
Explanation:To find the distance between the harbor and the island, we need to calculate the average speed of the motorboat for the entire trip. Since the average speed on the outbound trip was 10 knots and the average speed on the return trip was also 10 knots, we can conclude that the boat traveled at a constant speed throughout the trip. Let's assume the distance between the harbor and the island is 'd'.
Since speed = distance / time, we can calculate the time taken for each leg of the trip using the average speeds and the total time of 4.0 hours:
Time taken for the outbound trip = d / 10 knots
Time taken for the return trip = d / 10 knots
Since the total time is 4.0 hours, we can write the equation: d / 10 + d / 10 = 4.0
Simplifying the equation, we get: 2d / 10 = 4.0
Multiplying both sides by 10, we get: 2d = 40
Dividing both sides by 2, we get: d = 20
Therefore, the distance between the harbor and the island is 20 nautical miles.

So f(5) or the value of the function when x = 5 is -5.
The perimeter of a rectangle is 48 in the length of 6 in greater than the width Define a variable and write an equation to represent the situation solve the system by using substitution
Answer:
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of a rectangle is 48 in. It means that
48 = 2(L + W)
L + W = 48/2
L + W = 24 - - - - - - - - - 1
the length of the rectangle is 6 in greater than the width. It means that
L = W + 6
Substituting L = W + 6 into equation 1, it becomes
W + 6 + W = 24
2W + 6 = 24
2W = 24 - 6 = 18
W = 18/2 = 9
L = W + 6 = 9 + 6 = 15
Final answer:
The student's problem involves finding the length and width of a rectangle given its perimeter and the fact that the length is 6 inches greater than the width. To solve it, we defined the width as a variable, set up an equation based on the perimeter, and used substitution to find that the width is 9 inches and the length is 15 inches.
Explanation:
The perimeter of a rectangle is given by the formula 2(length + width). In the stated problem, we are given the total perimeter (48 inches) and told that the length is 6 inches greater than the width. We can define the width as w and the length as w + 6. So, the perimeter equation is:
2(w + (w + 6)) = 48
Simplify the equation: 2(2w + 6) = 48.Distribute the 2: 4w + 12 = 48.Subtract 12 from both sides: 4w = 36.Divide by 4 to find w: w = 9.Now that we have the width, we can find the length using substitution:
w + 6 = 9 + 6 = 15
Therefore, the width is 9 inches and the length is 15 inches.

Company A charges $70.50 and 18 cents per mile. Company B charges $30.50 and 11 cents per mile. How much more does company A charge for x miles than company B?
Answer:
Step-by-step explanation:
Let x represent the number of miles with either company A or company B.
Company A charges $70.50 and 18 cents per mile. Converting 18 cents to dollars, it becomes
18/100 = $0.18
Total cost of x miles with company A would be
0.18x + 70.50
Company B charges $30.50 and 11 cents per mile. Converting 11 cents to dollars, it becomes
11/100 = $0.11
Total cost of x miles with company B would be
0.11x + 30.50
For the amount that company A charges more than company B, it becomes
0.18x + 70.50 - 0.11x + 30.50
0.18x - 0.11x + 70.5 - 30.5
0.07x + 40
Company A charges 0.07x + 40 more than company B

B. −30
C. 81
D. 189
E. 729
Answer:
729
Step-by-step explanation:
The first term is 1 in the geometric sequence 1, −3, 9, −27, . .
First find out the nth term formula for the geometric sequence
[tex]a_n=a_1(r)^{n-1}[/tex]
where a_1 is the first term =1
r is the common ratio,
[tex]\frac{-3}{1}=-3[/tex]
[tex]\frac{9}{-3}=-3[/tex]
[tex]\frac{-27}{9}=-3[/tex]
r=-3, a_1=1
[tex]a_n=a_1(r)^{n-1}[/tex]
[tex]a_n=1(-3)^{n-1}[/tex]
Now find out the seventh term, n=7
[tex]a_7=1(-3)^{7-1}=729[/tex]
To find the seventh term of the geometric sequence 1, −3, 9, −27, ..., we calculate the common ratio and use it in the formula for the n-th term. The common ratio is −3 and the seventh term turns out to be 729. So the correct option is E.
Explanation:Calculating the SEVENTH Term of a Geometric Sequence
The given geometric sequence is 1, −3, 9, −27, ... and we are asked to find the seventh term. In a geometric sequence, each term after the first is found by multiplying the previous term by a constant called the common ratio (r). To find the common ratio, we can divide the second term by the first term, or the third term by the second term, and so on.
Common ratio (r) calculation:
Divide the second term (−3) by the first term (1), which gives us r = −3.
To find the seventh term, we use the formula for the n-th term of a geometric sequence, which is:
a_n = a_1 × r^(n-1), where a_n is the n-th term, a_1 is the first term, and n is the term number.
Seventh term calculation:
a_7 = 1 × (−3)^(7-1) = 1 × (−3)^6. Since −3 to an even power is positive, the answer is 1 × 3^6 = 729.
Therefore, the seventh term of the geometric sequence is 729.

Which is the graph of 3x – 2y = 6? A coordinate plane with a line passing through (negative 2, 0) and (0, 3). A coordinate plane with a line passing through (0, negative 3) and (2, 0). A coordinate plane with a line passing through (0, negative 2) and (3, 0). A coordinate plane with a line passing through (negative 3, 0) and (0, 2).
Answer:
The answer to your question is A coordinate plane with a line passing through (0, -3) and (2,0)
Step-by-step explanation:
Line
3x - 2y = 6
Solve for y
-2y = -3x + 6
y = 3/2 x - 3
Find "y" when x = 0
y = 3/2(0) - 3
y = -3 Point (0, -3)
Find "x" when y = 0
0 = 3/2x - 3
3 = 3/2 x
x = 6/3
x = 2 Point (2, 0)
The graph of the equation 3x - 2y = 6 passes through the points (0, -3) and (2, 0). This conclusion is reached after rearranging the equation into the slope-intercept form and comparing the slope and the y-intercept with coordinates of the given lines.
Explanation:To find the correct graph for the equation 3x - 2y = 6, we first need to rearrange the equation in the slope-intercept form (y = mx + b), where m is the slope of the line and b is the y-intercept.
We rearrange our equation as follows: 3x - 6 = 2y. Simplifying, we get y = 1.5x - 3.
This equation tells us that the y-intercept (where the line crosses y-axis) is -3, and the slope is 1.5, in other words, for each step in positive x-direction, y increases by 1.5 steps.
Now looking at our coordinate plane options, the graph that fits this description is the one with a line passing through the points (0, -3) and (2, 0). Hence, this is the graph of the given equation.

A baseball player got 52 hits one season. He got h of the hits in one game. What expression represents the number of hits he got in the rest of the games?
Answer:
The expression that represents the number of hits he got in the rest of the games is [tex]t=52-h[/tex].
Step-by-step explanation:
Given:
Number of hits in one season = 52 hits
Number of hits in one game = 'h'
We need to write expression that represents the number of hits he got in the rest of the games.
Solution:
Let the number of hits he got in the rest of the games be 't'.
Now we can say that;
The number of hits he got in the rest of the games is equal to Number of hits in one season minus Number of hits in one game.
framing in equation form we get;
[tex]t=52-h[/tex]
Hence expression that represents the number of hits he got in the rest of the games is [tex]t=52-h[/tex].
Answer:
52 - h
Step-by-step explanation:
Simplify: 52 - h
