BRAINLIEST!!!18. Point P Is Chosen At Random On EH. Find The Probability That P Is On FG.

Answers

Answer 1

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

The total length of this line is 15 units. FG is 6 units long.

This means that the probability of p being on FG would be [tex]\frac{6}{15}[/tex] which can be simplified to [tex]\frac{2}{5}[/tex]

Answer 2

Answer:

2/5

Step-by-step explanation:

Line EH has three line segments:

EF which measure 4

FG which measures 6

GH which measures 5

The total measure of the line (EH) = 4 + 6 + 5 = 15

So if we are calculating the probability of landing on FG,

6 / 15

Reduce the fraction to make,

2 / 5

K=6.5

at a clothing store, jackets are on sale for 30% off.sale tax is 5%.which expression will calculate the total cost of a jacket with an original price of x

Answers

The expression to calculate the total cost of a jacket with an original price of x is 0.7x + 5 % of 0.7x

Solution:

Given that at a clothing store, jackets are on sale for 30% off

Sales is 5 %

To find: Expression to calculate the total cost of jacket

Let "x" be the original price of Jacket

Price of jacket after offer = original price of Jacket - 30 % of original price

Price of jacket after offer = x - 30 % of x

Price of jacket after offer = [tex]x - \frac{30}{100}x = 0.7x[/tex]

The total cost of jacket is sum of price of jacket after offer and sales tax

total cost of jacket = price of jacket after offer + sales tax

total cost of jacket = 0.7x + 5 % of 0.7x

Thus the expression to calculate the total cost of a jacket with an original price of x is 0.7x + 5 % of 0.7x

Answers

Answer:C: x = the quantity of 1 plus or minus the square root of 17 all over 2

Step-by-step explanation:

Answer:

The answer is option C: x = the quantity of 1 plus or minus the square root of 17 all over 2

Step-by-step explanation:

The general form of the quadratic equation is ax² + bx + c = 0

The general solution of the quadratic equation is:

[tex]x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

The given equation is x² − x − 4 = 0

So, a = 1 , b = -1 and b = -4

Substitute with a , b and c at the formula of the general solution.

The solution of the given equation = [tex]\frac{-(-1) \pm \sqrt{(-1)^2 - 4 * 1 * (-4)} }{2*1}= \frac{1\pm \sqrt{1 +16} }{2}=\frac{1\pm \sqrt{17} }{2}[/tex]

Comparing the solution with the given options

So, the answer is option C: x = the quantity of 1 plus or minus the square root of 17 all over 2

A = an employee is a female

B = an employee is under the age of 30.

Use formula

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

There are 200 employees, 150 of them are female, then

There are 200 employees, 40 of them are under the age of 30, then

The probability of randomly selecting an employee who is a female or under the age of 30 is 85%, then

[tex]P(A\cup B)=0.85[/tex]

Answers

Answer:

The last is the correct option

"all real values except x not-equals 7 and the x for which f (x) not-equals negative 3"

Step-by-step explanation:

Domain and Range of Functions

Given the function f(x), the domain of f is the set of all the values that x can take such f(x) exists. The range of f is the set of all the values that f takes.

We have a problem where we have to find the domain of a composite function. Let's recall that being f and g real functions, then

[tex]g\circ f=g(f(x))[/tex]

is the composite function of f and g.

We know the domain of f is the set of all real values except 7, and the domain of g is the set of all real values except –3.

Since f is the innermost function, the domain of the composite function is directly restricted by the domain of f. So, x cannot be 7.

Now, g takes f as its independent variable, and we know the domain of g excludes -3. It can be found that f(x) cannot be -3 because it will cause g not to exist.

Thus, the domain of [tex]g\circ f[/tex] is

All real numbers except x=7 and those where f(x)=-3

On a number line, what number is 2/3 of the way from 7 to 13?

Answers

Answer:

That would be about 11.667

The number that is 2/3 of the way from 7 to 13 on a number line is 11. This is found by calculating 2/3 of the distance between the two numbers and adding it to the starting number.

To find the number that is 2/3 of the way from 7 to 13 on a number line, you first calculate the distance between the two numbers, which is 13 - 7 = 6. Then you take 2/3 of that distance, which is 2/3 * 6 = 4. Lastly, you add this result to the starting number, in this case, 7, giving you 7 + 4 = 11. Therefore, the number that is 2/3 of the way from 7 to 13 is 11.

In the half-life function Q(t)=28550⋅((34)h)(th) Q ( t ) = 28550 ⋅ ( ( 3 4 ) h ) ( t h ) , what is the half-life, h h , if (34)h=12 ( 3 4 ) h = 1 2 ?

Answers

The half-life h is calculated to be approximately 2.41.

To determine the half-life h from the given half-life function:

[tex]\[ Q(t) = 28550 \cdot \left( \frac{3}{4} \right)^{\frac{t}{h}} \][/tex]

we need to solve for h in the equation:

[tex]\[ \left( \frac{3}{4} \right)^h = \frac{1}{2} \][/tex]

To solve for  h , we take the natural logarithm (ln) of both sides of the equation:

[tex]\[ \ln \left( \left( \frac{3}{4} \right)^h \right) = \ln \left( \frac{1}{2} \right) \][/tex]

Using the logarithmic property [tex]\(\ln(a^b) = b \ln(a)\)[/tex], we get:

[tex]\[ h \ln \left( \frac{3}{4} \right) = \ln \left( \frac{1}{2} \right) \][/tex]

Now, solve for h :

[tex]\[ h = \frac{\ln \left( \frac{1}{2} \right)}{\ln \left( \frac{3}{4} \right)} \][/tex]

Calculate the natural logarithms:

[tex]\[ \ln \left( \frac{1}{2} \right) = \ln(0.5) \approx -0.6931 \\\[ \ln \left( \frac{3}{4} \right) = \ln(0.75) \approx -0.2877 \][/tex]

Now, divide these values to find  h :

[tex]\[ h = \frac{-0.6931}{-0.2877} \approx 2.41 \][/tex]

So, the half-life  h  is approximately:

[tex]\[ h \approx 2.41 \][/tex]

Therefore, the half-life  h  rounded to the nearest hundredth is:

h = 2.41

Fifty students in the seventh grade are trying to raise at least $2000 for sports supplies. They already raised $750. How much should each student raise in order to meet the goal? Write your answer as an inequality.

Answers

Answer:

x ≥ 25

Step-by-step explanation:

In the seventh grade, fifty students are trying for sports supplies to raise at least $2000. They already have $750.

Let us assume that each student has to raise $x more to meet the goal.

Then, a total of 50 students will raise $50x more.

Therefore, the inequality to solve for x will be  

750 + 50x ≥ 2000

⇒ 50x ≥ 1250

x ≥ 25 (Answer)

Final answer:

Each seventh grade student should raise at least $25 in order to collectively meet the goal of raising $2000 for their sports supplies after having already raised $750.

Explanation:

The goal amount for the seventh grade sports supplies fundraiser is $2000. They have already raised $750, leaving them with $1250 still needed to reach their goal. If there are 50 students working on the fundraiser, we can set up an inequality to determine how much money each student should raise minimally to meet the goal of $2000. Here's the inequality:

Let x be the amount each student needs to raise.

50x + $750 ≥ $2000

To solve for x, we subtract $750 from both sides of the inequality:

50x ≥ $2000 - $750

50x ≥ $1250

Now divide both sides by 50 to find the amount each student should raise:

x ≥ $1250 / 50

x ≥ $25

Therefore, each seventh grade student should raise at least $25 to meet the $2000 goal.
