The equation c = 13.99p represents the proportional relationship between the total cost (c) and the number of pounds (p) of shrimp at a grocery store. Which description is true, based on the equation of the proportional relationship? For $13.99, you can buy 13.99 pounds of shrimp. For $13.99, you can buy 1 pound of shrimp. For $1, you can buy 13.99 pounds of shrimp. For $0.01, you can buy 1 pound of shrimp.
The statement that is true about the proportional relationship:
C = 13.99*p
Is "For $13.99, you can buy 1 pound of shrimp"
Which description is true?
Here we have the proportional relationship:
C = 13.99*p
Where c is the total cost and p is the number of pounds of shrimp bought at a grocery store.
This means that if you buy one pound (p = 1) the total cost will be:
C = 13.99*1
C = 13.99
So each pound costs $13.99
Then the true statement about the proportional relationship is:
" For $13.99, you can buy 1 pound of shrimp."

13. Find (f . g)(x) if f(x)=7x³-5x²+42x-30 and g(x)=7x-5.
(f . g)(x)=49x⁴-269x²-150
(f . g)(x)=49x⁴+269x²+150
(f . g)(x)=49x⁴-70x³+319x²-420x+150
(f. g)(x)=49x⁴+70x³-319x²+420x-150
(f . g)(x) is multiplication of f(x) and g(x). So,

How to multiply two functions?A new function that is the product of the original two functions is created when two independent functions are multiplied together.
To multiply two functions together, perform these steps:
Each term in the first function should be multiplied by each term in the second function.Combine related terms to produce the desired function.The highest-order term in the new function should come first.In given question we have two functions
f(x) = 7x³-5x²+42x-30
g(x) = 7x - 5
we need to find (f.g)(x) that is nothing but multiplication of f(x) and g(x).
So multiplying both the functions, we get

Write a linear equation
representing a line passing
through points (3, 5) and (-8,
5).
Hello,
I hope you and your family are doing well!
The answer is y = 5 (See below for the explanation).
To find a linear equation representing a line passing through two points, you can use the slope-intercept form of the equation, which is written as y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
To find the slope of the line, you can use the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates of the two given points, we get:
m = (5 - 5) / (-8 - 3) = 0 / -11 = 0
Since the slope of the line is 0, the line is horizontal and passes through both points at the same y-value (5). The x-intercept (the point at which the line crosses the x-axis) is not relevant in this case.
Therefore, the linear equation representing this line is y = 5.

There are two right circular cylinders. The radius of the first cylinder is 3 centimeters, and its height is 5 centimeters. The radius of the second cylinder is 15 centimeters, but its height is also 5 centimeters. What is the ratio of the volume of the second cylinder to the volume of the first cylinder?
The ratio of the volume of the second cylinder to the volume of the first cylinder is 25.
To find the ratio of the volume of the second cylinder to the volume of the first cylinder, we need to calculate the volumes of both cylinders and then compare them.
The formula to calculate the volume of a right circular cylinder is given by V = πr^2h, where V represents the volume, r is the radius, and h is the height.
For the first cylinder:
Radius (r₁) = 3 centimeters
Height (h₁) = 5 centimeters
Volume of the first cylinder (V₁) = π * (3 cm)^2 * 5 cm
= 45π cm³
For the second cylinder:
Radius (r₂) = 15 centimeters
Height (h₂) = 5 centimeters
Volume of the second cylinder (V₂) = π * (15 cm)^2 * 5 cm
= 1125π cm³
To find the ratio of the volumes, we divide the volume of the second cylinder by the volume of the first cylinder:
Ratio = V₂ / V₁
= (1125π cm³) / (45π cm³)
= 25
Therefore, the ratio of the volume of the second cylinder to the volume of the first cylinder is 25.

A sample of 200g of an isotope decays to another isotope according to the function A(t)= 200е⁻⁰⁰⁵⁴⁺ ,where t is the time in years
(a) How much of the initial sample will be left in the sample after 25 years?
(b) How long will it take the initial sample to decay to half of its original amount?
(a) After 25 years, about __g of the sample will be left.
(Round to the nearest hundredth as needed.)
After 25 years, about 52g of the sample will be left and the sample never reaches half of its original amount
How to determine the sample after 25 yearsFrom the question, we have the following parameters that can be used in our computation:
A(t)= 200е⁻⁰⁰⁵⁴⁺
Also from the question, we have
The variable t represents the number of years
This means that
t = 25, in this case
So, we have
A(25)= 200е⁻⁰⁰⁵⁴ ˣ ²⁵
Evaluate the above equation
A(25)= 51.848052128
Approximate
A(25) = 52
This means that the remaining sample is 52 grams
When the sample decays to reach half the initial valueHere, we have
A(t) = 0.5 * 200
A(t) = 100
Substitute the known values in the above equation, so, we have the following representation
200е⁻⁰⁰⁵⁴⁺ = 100
Divide both sides by 100
е⁻⁰⁰⁵⁴⁺ = 0.5
Take the natural logarithm of both sides
0.054t = -0.69314718056
So, we have
t = -0.69314718056/0.054
Evaluate
t = -13
Time cannot be negative

How much should you invest at 3% simple interest in order to earn $65 interest in 16 months?
Answer:
To earn $65 in interest in 16 months at a simple interest rate of 3%, you would need to invest $2,166.67. The formula for calculating simple interest is I = P * R * T, where I is the interest earned, P is the principal amount invested, R is the interest rate, and T is the time in years. In this case, we are given that the interest rate is 3%, the time is 16 months, and the interest earned is $65, so we can plug these values into the formula to solve for the principal amount invested:I = P * R * T
$65 = P * 0.03 * (16/12)
$65 = P * 0.03 * (4/3)
$65 = P * 0.01
P = $2,166.67Therefore, to earn $65 in interest in 16 months at a simple interest rate of 3%, you would need to invest $2,166.67.

A factory produces 3 diesel-generator sets per week. At the end of each week, the sets are tested. If the sets are acceptable, they are shipped to purchasers. The probability that a set proves to be acceptable is 0.70. The second possibility is that minor adjustments can be made so that a set will become acceptable for shipping; this has a probability of 0.20. The third possible outcome is that the set has to go to the diagnostic shop for major adjustment and be shipped at a later date; this has a probability of 0.10. Outcomes for different sets are independent of one another. (a) Find the probability of each possible number of sets, for one week’s production, which are acceptable without any adjustment. (b) What is the expected number of sets which are tested and found to be acceptable without adjustment? (c) What is the cumulative probability distribution for the number of sets which are tested and found to be acceptable without adjustment? Sketch the corresponding graph
(a) The probability of each possible number of sets that are acceptable without any adjustment can be found using the binomial distribution formula:
P(x) = (n choose x) * p^x * (1-p)^(n-x)
Where:
P(x) is the probability of x successes in n trials
n is the number of trials (in this case, the number of sets produced in a week)
x is the number of successes (in this case, the number of sets that are acceptable without any adjustment)
p is the probability of success (in this case, the probability that a set is acceptable without any adjustment, which is 0.70)
Plugging in the values, we get:
P(0) = (3 choose 0) * 0.70^0 * (1-0.70)^(3-0) = 0.028
P(1) = (3 choose 1) * 0.70^1 * (1-0.70)^(3-1) = 0.081
P(2) = (3 choose 2) * 0.70^2 * (1-0.70)^(3-2) = 0.162
P(3) = (3 choose 3) * 0.70^3 * (1-0.70)^(3-3) = 0.126
(b) To find the expected number of sets that are tested and found to be acceptable without adjustment, we can use the formula:
E(x) = n * p
Plugging in the values, we get:
E(x) = 3 * 0.70 = 2.1
The expected number of sets that are tested and found to be acceptable without adjustment is 2.1.
(c) The cumulative probability distribution for the number of sets that are tested and found to be acceptable without adjustment is the sum of the probabilities of each possible number of successes. For example, the probability of 0 or 1 successes is the sum of the probabilities of 0 and 1 successes: P(0 or 1) = P(0) + P(1) = 0.028 + 0.081 = 0.109. The probability of 0, 1, or 2 successes is the sum of the probabilities of 0, 1, and 2 successes: P(0 or 1 or 2) = P(0) + P(1) + P(2) = 0.028 + 0.081 + 0.162 = 0.271.
The cumulative probability distribution for the number of sets that are tested and found to be acceptable without adjustment is:
P(0) = 0.028
P(0 or 1) = P(0) + P(1) = 0.028 + 0.081 = 0.109
P(0 or 1 or 2) = P(0) + P(1) + P(2) = 0.028 + 0.081 + 0.162 = 0.271
P(0 or 1 or 2 or 3) = P(0) + P(1) + P(2) + P(3) = 0.028 + 0.081 + 0.162 + 0.126 = 0.397
The corresponding graph would be a step function with a step at each possible value of x (in this case, 0, 1, 2, and 3) and the corresponding probability at each step.

Car sticker price =
You can afford the amount of $24588.44 expensive a car.
What exactly is a monthly payment?A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.
The monthly payment = Total payback / No. of payment
$325 = Total payback / 108
Total payback = $325 x 108 = $351,00
Let the affordable amount of the car would be P
The total payback = P× r/100 × T + P
Here P, r = 4.75, and T = 9 years
$351,00 = P × (4.75/100 × 9 + 1)
$351,00 = P × ( 0.4275 + 1)
$351,00 = P × 1.4275
P = 351,00 / 1.4275

What is an inequality?A relationship between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. So inequality results from an imbalance. For instance, let's say you want to spend $250 on a new bicycle but only have $225. The fact that you are comparing two non-equal numbers makes it an inequality as well.
When two quantities are equal, the symbol "=" is used, and when they are not equal, the symbol "" is used to denote that. When two values are not equal, the first value may be greater than (>), less than (<), greater than equal to (≥), less than equal to (≤). In light of the example given above, 250 > 225.

Where are the residual values shown on a residual plot?
A) on the y-axis
B) on the x-axis
C) on the line of best fit
D) on the x and y-axis
The coordinate on which the residual values are shown on a residual plot is: A) on the y-axis.
What is a residual value?A residual value can be defined as a difference between the measured (given or observed) value from a residual plot (scatter plot) and the predicted value from a residual plot (scatter plot).
Mathematically, the residual value of a data set can be calculated by using this formula:
Residual value = given value - predicted value
In Mathematics, the independent variable (fitted values) are generally plotted on the x-axis of a residual plot (scatter plot) while the residual value is plotted on y-axis of a residual plot (scatter plot).
In conclusion, a line of best fit simply refers to a trend line on a residual plot (scatter plot).

which of the following inference tests is not appropriate for a comparison of two means in a causal comparative study?
a. The Mann-Whitney U test
b. ANOVA
c. Chi-Square
d. A t test for independent means
The Mann-Whitney U test is not appropriate for a comparison of two means in a causal comparative study.
What is Mann-Whitney U test?To determine if two samples are likely to come from the same population, researchers employ the Mann Whitney U test, also known as the Mann Whitney Wilcoxon Test or the Wilcoxon Rank Sum Test (i.e., that the two populations have the same shape). When a continuous level variable is measured across all observations in two groups and we wish to test if the distribution of this variable differs between the two groups but we are unable to assume normality in both groups, we use the Mann-Whitney test.
