Tanya yearly salary is

$35000 + 8% of her sales

Let her sales be x

Since, her sales is x

35000 + 0.08x > salary

To determine her necessary sales to earn over $50, 000

Let $50, 000 be her benchmark salary

35,000 + 0.08 * x > 50000

35000 + 0.08x > 50000

0.08x > 50000 - 350000

0.08x > 15000

Divide both sides by 0.08

0.08x/0.08 > 15000/0.08

x > 15000 / 0.08

x > 187,500

Therefore, she will need a sales of 188,000 and above to earn above $50,000

Sandy needs a total of 5.25 cups of milk to make three and one-half quarts of yogurt.

To find the total amount of milk Sandy needs to make three and one-half quarts of yogurt, we'll use the given information that one and one-half cups of milk are used to make one quart of yogurt.

First, we need to determine the amount of milk required for one quart of yogurt. Given that one and one-half cups of milk are needed, we can write this as:

1 quart = 1.5 cups

Next, we calculate the amount of milk required for three and one-half quarts of yogurt. To do this, we multiply the amount of milk needed for one quart by the number of quarts:

3.5 quarts * 1.5 cups/quart = 5.25 cups

Therefore, Sandy needs a total of 5.25 cups of milk to make three and one-half quarts of yogurt.

It's important to note that we assume a consistent ratio of milk to yogurt across all quantities. This means that for every quart of yogurt, Sandy requires one and one-half cups of milk.

In summary, to make three and one-half quarts of yogurt, Sandy needs a total of 5.25 cups of milk.

The correct answer is option D. No, because the sample sizes are not large enough to assume the distribution of the difference in sample means is approximately normal.Researchers investigated whether there is a difference between two headache medications, R and S.

Researchers measured the mean times required to obtain relief from a headache for patients taking one of the medications. From a random sample of 75 people with chronic headaches, 38 were randomly assigned to medication R and the remaining 37 were assigned to medication S. The time, in minutes, until each person experienced relief from a headache was recorded. The sample mean times were calculated for each medication.To construct a confidence interval, we require that some conditions are satisfied. The assumptions that should be met for inference with a confidence interval for the difference in population means are as follows:The data is independent;The data in each group should be roughly normally distributed;Both groups have the same variance, and each group should have a large enough sample size so that the central limit theorem (CLT) holds. The CLT holds for the difference in the sample means since both samples are taken from a population that is normally distributed. We can also assume that the sample size is large enough to use the t-distribution since each sample has more than 30 observations. As a result, all of the conditions have been met. As a result, we may employ a t-distribution to make inferences about the population difference between the two headache medications.

Step-by-step explanation:

The time it takes the ball to strike the ground after it is thrown, found using the kinematic equation, H = -16·t² - 24·t + 200 is approximately 2.86 seconds

A kinematic equation is an equation of the motion of an object moving with a constant acceleration.

The direction in which the ball is thrown = Downwards

Height of the building = 200 foot

Initial velocity of the ball = 24 ft./s

The kinematic equation that indicates the height of the ball after t seconds is, H = -16·t² - 24·t + 200

At ground level, H = 0, therefore;

H = 0 = -16·t² - 24·t + 200

-16·t² - 24·t + 200 = 0

-2·t² - 3·t + 25 = 0

t = (3 ± √((-3)² - 4 × (-2)×25))/(2×(-2))

t = (3 ± √(209))/(-4)

t =  (3 + √(209))/(-4) ≈ -4.36 and t =  (3 - √(209))/(-4)) ≈ 2.86

The correct answer is D. f(x) = 11x - 4 and g(x) = (x + 4)/11

To determine which pair of functions are inverses of each other, we need to check if the composition of the functions results in the identity function, which is f(g(x)) = x and g(f(x)) = x.

Let's test each option:

Option A:

f(x) = x/2 + 15

g(x) = 12x - 15

f(g(x)) = (12x - 15)/2 + 15 = 6x - 7.5 + 15 = 6x + 7.5 ≠ x

g(f(x)) = 12(x/2 + 15) - 15 = 6x + 180 - 15 = 6x + 165 ≠ x

Option B:

f(x) = ∛3x

g(x) = (x/3)^3 = x^3/27

f(g(x)) = ∛3(x^3/27) = ∛(x^3/9) = x/∛9 ≠ x

g(f(x)) = (∛3x/3)^3 = (x/3)^3 = x^3/27 = x/27 ≠ x

Option C:

f(x) = 3/x - 10

g(x) = (x + 10)/3

f(g(x)) = 3/((x + 10)/3) - 10 = 9/(x + 10) - 10 = 9/(x + 10) - 10(x + 10)/(x + 10) = (9 - 10(x + 10))/(x + 10) ≠ x

g(f(x)) = (3/x - 10 + 10)/3 = 3/x ≠ x

Option D:

f(x) = 11x - 4

g(x) = (x + 4)/11

f(g(x)) = 11((x + 4)/11) - 4 = x + 4 - 4 = x ≠ x

g(f(x)) = ((11x - 4) + 4)/11 = 11x/11 = x

Based on the calculations, only Option D, where f(x) = 11x - 4 and g(x) = (x + 4)/11, satisfies the condition for being inverses of each other. Therefore, the correct answer is:

D. f(x) = 11x - 4 and g(x) = (x + 4)/11

The number of students is the cost of the trip the same at each museum is 25

When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.

 y = 75 +7x . . . . . cost for x students to visit the science center

 y = 50 +8x . . . . cost for x students to visit the natural history museum

Subtracting the first equation from the second, we get

 0 = -25 +x

 25 = x . . . . . add 25; the number of students such that costs are equal

The cost will be the same either place for 25 students.

Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is

 $25/($1 /student) = 25 students.

This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).

Cost per student       $8                           $5

Fixed cost                  $5                         $20

Let the number of students = x

The total cost at the Science Center = 5 + 8x

The total cost at the History Museum = 20 + 5x

For the cost to be the same at either center:

5 + 8x = 20 + 5x

3x = 15

x = 5

Let's analyze the given probability mass function (pmf) for the random variable X. We know that P(X = i) = 21 for some fixed α in the set of real numbers, R. However, it seems there is an error in the given pmf value. The probability of any specific value in a discrete probability distribution should be between 0 and 1. Therefore, it is not possible for P(X = i) to equal 21.

To proceed with finding EX, we need a valid pmf. Without further information or clarification, it is not possible to determine the expected value of X.

Moving on to the second part of the question, we introduce a new random variable Y = X mod 3. The modulus operator (mod) finds the remainder when dividing X by 3. In other words, Y represents the numbers in X that leave a remainder of 1 when divided by 3.

To find P(Y = 1), we need to calculate the probability that Y takes the value 1. Since Y represents the remainder when dividing X by 3, Y can only take the values 0, 1, or 2.

To calculate P(Y = 1), we sum up the probabilities of all the values in X that leave a remainder of 1 when divided by 3. Mathematically, we can express this as:

P(Y = 1) = P(X = 1) + P(X = 4) + P(X = 7) + ...

However, since the pmf values were given incorrectly, it is not possible to compute P(Y = 1) without a valid pmf. Therefore, we cannot provide a specific numerical answer for P(Y = 1) in this case.

In summary, without a valid pmf for X, it is not possible to determine the expected value of X (EX) or calculate the probability P(Y = 1) for the random variable Y = X mod 3.

Answer: 160 sq. feet

Step-by-step explanation:

Given: Dimension of rectangular pool :

Length =  20 feet

width = 15 feet

Area of rectangular pool = length x width

= 20 feet  × 15 feet

= 300 sq. feet

Now, Length of deck = 20 feet + 4  feet+ 4   feet           (For both sides)

= 28 feet

width of deck = 15 feet + 4  feet+ 4   feet  = 23 feet

Area of deck including pool = 20 feet  ×  23 feet

= 460 sq. feet

Area of deck = (Area of deck including pool ) -(Area of rectangular pool)

= 460 - 300 sq. feet

= 160 sq. feet

Hence, the area of the surface of the deck= 160 sq. feet

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. These side lengths do not make a right triangle.

Answer:

No

Step-by-step explanation:

In a triangle, one side length must be smaller than the other side lengths added together. We'll say R = 4, T = 8, and S = 3.

R + T > S

R + S < T

T + S > R

Since side R + side S is not greater than side T, those three side lengths don't create a triangle.
