As the question does not specify any order or arrangement for the boxes of Wake up cereal, the boxes can be organized in one single way: 10 boxes of crispy Wake up cereal and 10 boxes of crunchy Wake up cereal.
Explanation:The question asks how many ways 10 boxes of crispy Wake up cereal and 10 boxes of crunchy Wake up cereal can be organized. This appears to be a problem of combinations or permutations. However, since there are only two types of cereal and the question only asks about the total number of boxes, not their order, the numbers of ways will be the same no matter how they're arranged. Therefore, the only answer in this case would be one single way: 10 boxes of crispy and 10 boxes of crunchy.

Determine if the Mean Value Theorem for Integrals applies to the function f of x equals 2 times the square root of x on the interval [0, 4]. If so, find the x-coordinates of the point(s) guaranteed to exist by the theorem.
No, the theorem does not apply.
Yes, x = 1.
Yes, x equals 8 over 3.
Yes, x equals sixteen divided by 9.
[tex]f(x)=2\sqrt x[/tex] is continuous on [0, 4] and differentiable on (0, 4), so the MVT holds. We have
[tex]f'(x)=\dfrac1{\sqrt x}[/tex]
so that by the MVT, there is some [tex]c\in(0,4)[/tex] such that
[tex]f'(c)=\dfrac{f(4)-f(0)}{4-0}\implies\dfrac1{\sqrt c}=\dfrac{2\sqrt4}4=1[/tex]
[tex]\implies1=\sqrt c\implies \boxed{c=1}[/tex]
Answer:
x= 16/9
Step-by-step explanation:
[tex]f(x) = 2\sqrt{x}[/tex] is differentiable on [0,4] so the Mean Value Theorem For Integrals applies.
Average Value of the Integral:
[tex]\frac{1}{b-a} \int\limits^b_a {f(x)} \, dx = \frac{1}{4-0} \int\limits^4_0 {2\sqrt{x} } \, dx[/tex]
After evaluating you will get [tex]\frac{8}{3}[/tex]
Now, this is the average value so you still need to find the x-value using the original equation:
[tex]\frac{8}{3} =2\sqrt{x}\\\\\frac{4}{3} = \sqrt{x}\\\\\frac{16}{9} =x[/tex]

Kendra sold 200 shares through her broker on June 8. The price per share was $22.10. The broker charged her a 0.5% commission on the total value. What was Kendra’s return on the trade?
A. $4,397.90
B. $4,420.00
C. $4,596.90
D. $4,620.00
Answer:
A. $4397.9
Explanation:
We are given that Kendra sold 200 shares and that the price per share was $22.1
This means that:
Total value = 200 * 22.1 = $4420
Now, we know that the broker charged 0.5% commission on the total value
This means that:
Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1
Therefore,
Kendra's return = Total value - broker's charge
Kendra's return = 4420 - 22.1 = $4397.9

James bought two T-shirts and one pair of jeans at an online store and paid $40, not including taxes, for his purchase. A month later, the same store sold the T-shirts and jeans at a 50% discount from their original prices. James bought two T-shirts and five pairs of jeans for $60, not including taxes.
Answer:
The T-shirts cost $10 and the jeans cost $20.
Step-by-step explanation:
I guess you want to find the cost of the T-shirts and jeans at his first buy,
Let the cost be $t and $j for T-shirts and jeans respectively.
Then we have the system:
2t + j = 40...................(1)
and a month later:
0.5*2t + 0.5*5j = 60
t + 2.5j = 60................(2)
Multiply by - 2:
-2t - 5j = -120.............(3)
Adding equations (1) and (3):
-4j = -80
j = -80 / -4
j = $20.
Substituting j = 20 into equation (2):
t + 2.5(20) = 60
t = 60 - 50
t = $10.
t = $55
A function is graphed on the coordinate plane.
what is the value of the function when x = 4
Answer:
1
Step-by-step explanation:
y = mx + b
y = 1/2 x - 1
y = 1/2 (4) - 1
y = 2 - 1
y = 1
When x = 4, the function y = (1/2)x - 1 evaluates to y = 1. This linear equation has a slope of 1/2 and a y-intercept of -1.
To find the value of the function y = (1/2)x - 1 when x = 4, you simply need to substitute x = 4 into the equation and solve for y:
y = (1/2)(4) - 1
y = 2 - 1
y = 1
So, when x = 4, the value of the function y is 1.
In a more general sense, this equation represents a linear function with a slope of 1/2 and a y-intercept of -1. The slope (1/2) represents the rate of change, meaning that for every unit increase in x, y increases by 1/2. The y-intercept (-1) is the value of y when x is 0.
When x = 4, as calculated above, y is 1. This means that if you were to plot this function on a coordinate plane, the point (4, 1) would lie on the graph.

Step-by-step explanation:
Simplify the expression.
sine of x to the second power minus one divided by cosine of negative x
(1−sin2(x))/(sin(x)−csc(x))
sin2x+cos2x=11−sin2x=cos2x
cos2(x)/(sin(x)−csc(x))csc(x)=1/sin(x)cos2(x)/(sin(x)− 1/sin(x))= cos2(x)/((sin2(x)− 1)/sin(x))sin2(x)− 1=-cos2(x)cos2(x)/(( -cos2(x))/sin(x))
=-sin(x)
Answer:
[tex]-cos \ x[/tex]
Step-by-step explanation:
First of all, we must have to understand what is the described expression in the paragraph
"sine of x to the second power minus one divided by cosine of negative x"
In this sentence, we need to identify what are the elements and operations involved in the expression.
In the sentence appears ""to the second power", "minus" and "divided by" (highlighted)
"sine of x to the second power minus one divided by cosine of negative x"
Therefore, the expression must has three operations:
"to the second power": refers to exponentiation"minus": refers to a substraction"divided by": refers to a divisionNow, we can identify what are the elements: "sine of x", "one" and "cosine of negative x"
"sine of x": refers to [tex]sin\ x[/tex]"one": refers to the number one (1)"cosine of negative x": refers to [tex]cos (-x)[/tex]Therefore, the expression is:
[tex]\frac{(sin\ x)^{2}-1}{cos(-x)}[/tex]
In order to find the simplified expression, we must have to apply these trigonometric identities:
[tex](sin\ x)^{2} = sin^{2}x[/tex][tex]sen\x^{2}x \ +\ cos\x^{2}x=1[/tex][tex]cos(-x)=cos\ x[/tex]Applying the first and third identities, we have:
[tex]\frac{(sin\ x)^{2}-1}{cos(-x)}=\frac{sin\x^{2}x-1}{cos\ x}[/tex]
From the second trigonometric identity, we have:
[tex]cos\x^{2}x=\ 1-sin\x^{2}x[/tex]
Now, multiplying by -1 in both sides:
[tex](-1)(cos\x^{2}x)=(-1)(1-\ sin\x^{2}x)[/tex]
In the left side, multiplying by -1 the sign of the expression changes:
[tex](-1)(cos\x^{2}x)=-cos\x^{2}x[/tex]
In the right side, multiplying by -1 changes the order of the substraction:
[tex](-1)(1-\ sin\x^{2}x)=\ sin\x^{2}x-1[/tex]
Putting all together:
[tex]-cos\x^{2}x=\ sin\x^{2}x-1[/tex]
Now, replacing values we have:
[tex]\frac{sin\x^{2}x-1}{cos\ x}=\frac{-cos\x^{2}x}{cos\ x}=-\frac{cos\x^{2}x}{cos\ x}[/tex]
Finally, the property of the first trigonometric identity (property of exponentiation) can be apply in this case:
[tex]-\frac{cos\x^{2}x}{cos\ x}=-\frac{(cos\ x)^{2}}{cos\ x}=-cos\ x[/tex]

C. f -1(x) = -2 + 5x
D. f -1(x) = -5x + 2
Answer:
B. f -1(x) = x + 2 / 5
[tex]f^{-1}(x)=\frac{x+2}{5}[/tex]
Step-by-step explanation:
To find the inverse of a function we need to interchange x and y an solve for y.
Since [tex]f(x)=y[/tex], then
[tex]f(x)=5x-2[/tex]
[tex]y=5x-2[/tex]
[tex]x=5y-2[/tex]
Add 2 to both sides
[tex]x+2=5y-2+2[/tex]
[tex]x+2=5y[/tex]
Divide both sides by 5
[tex]\frac{x+2}{5}=\frac{5y}{5}[/tex]
[tex]\frac{x+2}{5}=y[/tex]
[tex]y=\frac{x+2}{5}[/tex]
[tex]f^{-1}(x)=\frac{x+2}{5}[/tex]
We can conclude that the correct answer is B. f -1(x) = x + 2 / 5

solve system of equations using matrices.
Answer:
(t, t -1, t)
Step-by-step explanation:
You have three unknowns but only 2 equations, so you can't really SOLVE this...you can get a solution with a variable still in it (I forget what this is called. I think it refers to infinite many solutions). Here's how it works:
Set up your matrix:
[tex]\left[\begin{array}{ccc}1&-2&1\\2&-1&-1\\\end{array}\right] \left[\begin{array}{ccc}2\\1\\\end{array}\right][/tex]
You want to change the number in position 21 (the 2 in the scond row) to a 0 so you have y and z left. Do this by multiplying the top row by -2 then adding it to the second row to get that 2 to become a 0. Multiplying in a -2 to the top row gives you:
[tex]\left[\begin{array}{ccc}-2&4&-2\\2&-1&-1\\\end{array}\right]\left[\begin{array}{ccc}-4\\1\\\end{array}\right][/tex]
Then add, keeping the first row the same and changing the second to reflect the addition:
[tex]\left[\begin{array}{ccc}-2&4&-2\\0&3&-3\\\end{array}\right] \left[\begin{array}{ccc}-4\\-3\\\end{array}\right][/tex]
The second equation is this now:
3y - 3z = -3. Solving for y gives you y = z - 1. Let's let z = t (some random real number that will make the system true. Any number will work. I'll show you at the end. Just bear with me...)
lf z = t, and if y = z - 1, then y = t - 1. So far we have that y = t - 1 and z = t. Now we solve for x:
From the first equation in the original system,
x - 2y + z = 2. Subbing in t - 1 for y and t for z:
x - 2(t - 1) + t = 2. Simplify to get
x - 2t + 2 + t = 2 and x - t = 0, and x = t. So the solution set is (t, t - 1, t). Picking a random value for t of, let's say 2, sub that in and make sure it works. If:
x - 2y + z = 2, then t - 2(t - 1) + t = 2 becomes t - 2t + 2 + t = 2, and with t = 2, 2 - 2(2) + 2 + 2 = 2. Check it: 2 - 4 + 4 = 2 and 2 = 2. You could pick any value for t and it will work.
The frequency table was made using a deck of cards in which each card is numbered 1, 2, 3, or 4.
Create a bar graph by dragging the sliders on the horizontal axis to represent the probability distribution.
Answer:
Step-by-step explanation:
So the table means that there are 20 1's, 120 2's, 40 3's, and 20 4's.
The total number is 20+120+40+20 = 200.
So the probability of each is:
1: 20/200 = 0.10
2: 120/200 = 0.60
3: 40/200 = 0.20
4: 20/200 = 0.10
A bar graph that represents the probability distribution of each card is shown in the image below.
In Mathematics and Statistics, a frequency table can be used for the graphical representation of the frequencies or relative frequencies that are associated with a categorical variable or data set.
Based on the frequency, the total number of deck of cards can be calculated as follows;
Total number of deck of cards = 20 + 120 + 40 + 20
Total number of deck of cards = 200 cards.
Next, we would determine the probability distribution of each card as follows:
P(X = 1) = 20/200 = 0.10.
P(X = 2) = 120/200 = 0.60.
P(X = 3) = 40/200 = 0.20.
P(X = 4) = 20/200 = 0.10.

The cost in dollars to manufacture x pairs of shoes is given by 12,000 + 19x. This month, the manufacturer produced 1000 more pairs of shoes than last month. The average cost per pair dropped by $0.43.
a) Write an expression for the average cost per pair of shoes. Use this expression to write an equation to represent there situation.
b) Solve your equation
c) Are there any mathematical restrictions on the domain? Explain.
d) Determine reasonable domain in the context of the problem. Use your answers to parts I and II to answer the question.
Answer:
Imagination is more important than knowledge. --Clifford big red dog
Step-by-step explanation:
a) To find the average cost per pair of shoes, we need to divide the total cost by the number of pairs produced. Since the manufacturer produced x pairs of shoes, the total cost is 12,000+19x dollars. Therefore, the average cost per pair is given by:
Average cost per pair = (12,000+19x) / x
b) Using the given information that this month, the manufacturer produced 1000 more pairs of shoes than last month, we can represent the number of pairs produced last month as x−1000. Since the average cost per pair dropped by $0.43, the equation representing the situation is:
(12,000+19(x)−43(x)) / x=Average cost per pair
Solving this equation will provide us with the value of x.
c) Yes, there is a mathematical restriction on the domain. Since the number of pairs produced cannot be negative (it doesn't make sense to produce a negative number of shoes), the domain must be restricted to x>0.
d) In the context of the problem, the reasonable domain would be x>0 since the number of pairs of shoes produced cannot be negative. Additionally, since the manufacturer produced 1000 more pairs of shoes this month than last month, it's reasonable to assume that the number of pairs produced last month is also positive, leading to a positive change of 1000 pairs. Therefore, the domain would be x>1000.
a) The expression for the average cost per pair of shoes is given by:
Average cost per pair = (12,000+19x) / x
To represent the situation, we use this expression to equate the average cost per pair before and after the change in production.
b) Substituting x+1000 for x in the expression, we get:
(12,000+19(x+1000)) / (x+1000) = Average cost per pair
We solve this equation to find the value of x.
c) Yes, there's a restriction on the domain. Since the number of pairs of shoes cannot be negative, the domain must be x>0.
d) Considering the context, the reasonable domain is x>1000, as the manufacturer produced 1000 more pairs this month than last month. Also, x must be positive, so x>0. Thus, the domain is x>1000.
Complete Question:
The cost in dollars to manufacture x pairs of shoes is given by 12,000 + 19x. This month, the manufacturer produced 1000 more pairs of shoes than last month. The average cost per pair dropped by $0.43.

Identify the value of x and the length of each secant segment. HELP ASAP!!
Answer:
[tex]x=10, NL=8, NP=12[/tex]
Step-by-step explanation:
we know that
Applying the Intersecting secant Theorem
[tex]NL*NM=NP*NO[/tex]
substitute the given values and solve for x
[tex](3+5)*3=(2+x)*2[/tex]
[tex](8)*3=(2+x)*2[/tex]
[tex]24=(2+x)*2[/tex]
[tex]12=(2+x)[/tex]
[tex]x=12-2=10[/tex]
Find the value of NP
[tex]NP=(2+x)=2+10=12[/tex]
therefore
[tex]x=10, NL=8, NP=12[/tex]
Answer:
x = 7; NL = 12; NP = 20
