Step-by-step explanation:
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

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.

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.

The box plots show the student grades on a chapter test compared to the grades on a retest in the same class. Box plots titled Chapter Test versus Retest with horizontal axis labeled Class Marks ranges from 0 to 100. Chapter Test box plot with minimum between 40 and 50 and maximum between 90 and 100 has interquartile ranges approximately between 50 and 80 and median approximately at 70. Retest box plot with minimum between 50 and 60 and maximum approximately at 100 has interquartile ranges approximately between 60 and 80 and median approximately between 60 and 70. Which of the following best describes the information about the medians? The chapter test and retest medians are almost the same. The chapter test and retest Q3 are the same, but the chapter test has the higher median. The chapter test median is much higher than the retest median.

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

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]

A missile flies 20 miles in 10 minutes. Calculate the missile’s rate of change. a) 2 mi/min b) 10 mi/min c) 10 min/mi d) 1/2 mi/min
Answer: The answer would be 2 miles a minute.
Step-by-step explanation: Simply divide the miles by the minutes.
Missile's rate of change is 2 mi/ min
The rate of change in this instance is the speed that the missile is going at because rate of change is used to calculate how fast something is changing in respect to time.
Speed = Distance / Time
Distance = 20 miles
Time = 10 minutes
Rate of change:
= 20 / 10
= 2 miles per minute
The rate of change is therefore, 2 mi/ min
