Answer:
The answer is B. 1/12Step-by-step explanation:
step one:
From the problem state, we can actually conclude that Jamie wants to share the half sheet of cake among her 6 friends
step two:
we can express this problem mathematically as
[tex]=\frac{1}{\frac{2}{6} }[/tex]
we can inverse the denominator and use a multiplication sign instead
[tex]\\\\= \frac{1}{2}*\frac{1}{6}[/tex]
multiplying both denominators we have
[tex]\\\\= \frac{1}{12}[/tex]
The answer is B 1/12
attached is the question
Problem 18
The x should not be in the denominator. If it was in the denominator, then you wouldn't have a linear equation in the form y = mx+b
Instead, you should have written [tex]y = \frac{1}{17}x+\frac{63}{17}[/tex] or y = (1/17)x + 63/17
Comparing that to y = mx+b form, we see that m = 1/17 is the slope and b = 63/17 is the y intercept.

Manuel noticed that his cellphone bill reflected a monthly fee of
$40 as well as a charge for $0.05 per minute on the phone.
Manuel lost his August phone bill, but knows how much he paid
for the month. Which of the following functions will help Manuel
determine the amount of minutes he was on the phone based on
the cost of the bill?
Answer: (total amount paid - $40) / 0.05
Step-by-step explanation:
Given the following :
Monthly fee = $40
Additional fee = $0.05 per minute on phone
Given the the amount paid for the month is available, number of minutes he was on phone can be determined thus :
Total amount to be paid = monthly fee + additional fee
Additional fee = $0.05 × n
Where n = number of minutes on phone
Hence,
Total amount paid = $40 + $0.05n
If the amount paid is known, the number of minutes on phone can be calculated thus;
(Total amount paid - monthly fee) = $0.05n
n = (Total amount paid - monthly fee) / fee per minute on phone
(total amount paid - $40) / 0.05

Two things that are positively correlated are: population and income. age and weight in babies. age and weight in adults. income and gift giving. Two things that are negatively correlated are: temperature outside and ice cream sales. number of failing grades and likelihood of graduation. number of menu offerings and restaurant revenue. amount of income earned and amount of income tax paid.
1. Positively correlated: Population and income (A) - As population increases, income tends to increase. Option A is correct.
2. Negatively correlated: Temperature outside and ice cream sale - As temperature increases, ice cream sales tend to decrease. Option A is correct.
1. Two things that are positively correlated are population and income.
In this correlation, we observe that there is a positive relationship between the size of a population and the income level of that population.
This means that as the population of a region or country increases, the average income or total income tends to increase as well.
This correlation is often seen in developed countries where higher population centers are associated with better economic opportunities, leading to higher income levels.
2. Two things that are negatively correlated are temperature outside and ice cream sales.
In this negative correlation, we find that as the temperature outside increases, the sales of ice cream tend to decrease.
This is a common observation in many regions with seasonal changes. As the weather gets hotter (higher temperature), people may seek ways to cool down, and ice cream becomes a popular choice.
On the other hand, when the weather is colder, people are less likely to buy ice cream, leading to lower sales.
Hence, two things that are negatively correlated are temperature outside and ice cream sales. Option A is correct.

A paint-store chain produces and sells latex and semigloss paint. Based on long-range sales, the probability that a customer will purchase latex paint is 0.75. Of those that purchase latex paint, 60% also purchase rollers. But only 30% of semigloss paint buyers purchase rollers. A randomly selected buyer purchases a roller and a can of paint. What is the probability that the paint is latex?
Answer:
The probability that the paint latex = 0.857
Step-by-step explanation:
From the given information:
Let consider X to be the event that the customer has purchased the latex paint
Let consider Y to be the event that the customer has purchased semigloss paint.
Now, the probability of X i.e. P(X) = 0.75
SInce X and Y are mutually exhaustive)
P(Y) = 1 - P(X)
P(Y) = 1 - 0.75
P(Y) = 0.25
Similarly, Let Consider Z be the event that the customer has purchased a roller.
We are being told that P(Z|X) = 0.6
P(Z|Y) = 0.30
[tex]P(X|Z) = \dfrac{P(Z|X)(P(X) }{P(Z|X)*P(X)+P(Z|Y)*P(Y)}[/tex]
[tex]P(X|Z) = \dfrac{0.6 \times 0.75 }{(0.6 \times 0.75) +(0.3 \times 0.25)}[/tex]
[tex]P(X|Z) = \dfrac{0.45 }{(0.45) +(0.075)}[/tex]
[tex]P(X|Z) = \dfrac{0.45 }{0.525}[/tex]
[tex]P(X|Z) = 0.857[/tex]
Thus, the probability that the paint latex = 0.857
The concept of probability is used in order to determine the probability that the paint is latex and the probability is 0.857.
Given :
The probability that a customer will purchase latex paint is 0.75. The customer who purchase latex paint, 60% also purchase rollers.The customer who purchase semigloss paint, 30% also purchase rollers.First, determine the probability that a customer will purchase semigloss paint.
[tex]P(A) = 1- P(B)\\P(A) = 1 - 0.75\\P(A) = 0.25[/tex]
In the above expression P(B) is the probability that a customer will purchase latex paint.
Now, determine the probability that the paint is latex.
[tex]P(B|C) = \dfrac{P(C|B)\times P(B)}{P(C|B)\times P(B)+P(C|A)\times P(A)}[/tex]
Now, substitute the values of all the known terms in the above expression.
[tex]P(B|C) = \dfrac{0.6\times 0.75}{(0.6\times 0.75)+(0.3\times 0.25)}[/tex]
Simplify the below expression.
[tex]P(B|C) = \dfrac{0.45}{(0.45)+(0.075)}[/tex]
[tex]P(B|C) = \dfrac{0.45}{0.525}[/tex]
[tex]P(B|C) = 0.857[/tex]
So, the probability that the paint is latex is 0.857.

Angle bisector
Step-by-step explanation:
an angle bisector cuts an angle in half. COA goes from point c to point o to point a to make an angle. and OB is the exact middle of the angle. hope this helps :)
Find the value of x.
Please somebody help!!
The angle measuring 122 degrees is supplementary to the angle next to it.
Supplementary angles are angles that add up to 180 degrees.
180 = ? + 122
Subtract 122 from both sides.
58 = ?
Now we know that the triangle has a 58 degree angle and a 90 degree angle.
58 + 90 + x = 180
Combine like terms.
148 + x = 180
Subtract 148 from both sides.
x = 32 degrees

Is this the correct answer?
Step-by-step explanation:
Close. You correctly set up the integrals. When integrating e²ˣ:
∫ e²ˣ dx
½ ∫ 2 e²ˣ dx
½ e²ˣ + C
So the coefficient should be ½, not 2.
[eˣ − ½ e²ˣ]₋₁⁰ + [½ e²ˣ − eˣ]₀¹
[(e⁰ − ½ e⁰) − (e⁻¹ − ½ e⁻²)] + [(½ e² − e) − (½ e⁰ − e⁰)]
1 − ½ − e⁻¹ + ½ e⁻² + ½ e² − e − ½ + 1
-e⁻¹ + ½ e⁻² + ½ e² − e + 1
Answer:
[tex]\mathrm{Solution: - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2} + 1}[/tex]
Step-by-step explanation:
Your set up for the 'area of the shaded region' is absolutely correct. But when it comes to evaluating them, you are slightly off.
If we break this expression into parts, we have (eˣ - 2e²ˣ)dx on the interval [- 1 to 0] and (e²ˣ - eˣ)dx on the interval [0 to 1]:
(eˣ - 2e²ˣ)dx on the interval [- 1 to 0],
[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]
=> eˣdx - e²ˣdx on the interval [- 1 to 0]
=> [tex]1-\frac{1}{e}-\frac{e^2-1}{2e^2}[/tex]
(e²ˣ - eˣ)dx on the interval [0 to 1],
[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]
=> e²ˣdx - eˣdx on the interval [0 to 1],
=> [tex]\frac{e^2-1}{2}-e+1[/tex]
And now if we add the remaining fractions as expected, we will receive our answer. The set up would be as follows:
[tex]1-\frac{1}{e}-\frac{e^2-1}{2e^2}+\frac{e^2-1}{2}-e+1\\=> - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2}-1 + 2\\=> - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2} + 1\\\\\mathrm{Solution: - e + \frac{1}{2e^2}-\frac{1}{e}+\frac{e^2}{2} + 1}[/tex]

Suppose the waiting times in an emergency room are normally distributed with a mean (mean) of 40 and a standard deviation (sigma) of 10. A random sample of 25 persons waiting in the ER is selected. What is the probability that their average waiting time will be between 38 and 42 minutes
Answer:
0.68269
Step-by-step explanation:
When we are to find the z score for population where a random sample is picked, the z.score formula we use is
z = (x-μ)/Standard error, where
x is the raw score,
μ is the population mean
Standard error = σ/√n
σ is the population standard deviation
n = random number of samples
For : x = 38 minutes, μ = 40, σ = 10, n = 5
z = 38 - 40/10 /√25
= -2/10/5
= -2/2
= -1
Determining the probability value using z table
P(x = 38) = P(z = -1)
= 0.15866
For : x = 42 minutes, μ = 40, σ = 10, n = 25
z = 42 - 40/10 /√25
= 2/10/5
= 2/2
= 1
Determining the probability value using z table
P(x = 42) = P(z = 1)
= 0.84134
The probability that their average waiting time will be between 38 and 42 minutes is calculated as
P(-Z<x<Z)
= P(-1 < x < 1)
= P(z = 1) - P(z = -1)
= 0.84134 - 0.15866
= 0.68269
Therefore, the probability that their average waiting time will be between 38 and 42 minutes is 0.68269

Ten motors are packaged for sale in a certain warehouse. The motors sell for $100 each, but a double-your-money-back guarantee is in effect for any defectives the purchaser may receive. Find the expected net gain for the seller if the probability of any one motor being defective is 0.03. (Assume that the quality of any one motor is independent of that of the others.)
Answer:
expected gain = $940
Step-by-step explanation:
given data
sale in a certain warehouse = 10 moters
motors sell = $100
probability of defective = 0.03
solution
we get here expected total cost of 1 moter is the sum of product of gain and probabi;ity
EV = $100 × 0.97 + ( -$100 × 0.03)
EV = 94
so expected gain for seller on 10 moter is
expected gain = 10 × $94
expected gain = $940
