The function below shows the revenue for t-shirt sales. For every $1 decrease in price, 5 more t-shirts can be sold.

Part A: What is the maximum of this graph and what does the maximum represent?

Part B: What is the y-intercept of the graph? what does it represent?

Part C: Does the graph have zerosolution(s)? If so, identify the zero and what it represents?

Answer:

x = 3

y = -1

Step-by-step explanation:

(x-y) + (x+y) = 4 + 2

2x = 6

x = 3

sub x=3 into x+y=2

3+y=2

y=2-3

y=-1

Check by subbing x=3 and y=-1 into x-y=4

(3)-(-1) = 3+1 = 4

Answer:

4

Step-by-step explanation:

The current price per share is $32.59

The annual net earnings per share is $9.06

Therefore the PE ratio can be calculated as follows

= $32.59/$9.06

= 3.59

= 4 (to the nearest whole number)

Hence the PE ratio is 4

Answer:

[tex]Mean = 3.52[/tex]

Step-by-step explanation:

Given

[tex]Sample\ Size = 16[/tex]

[tex]Proportion = 22\%[/tex]

Required

Determine the mean of the proportion

The mean or expected value of a sample is calculated by multiplying the sample size by the proportion as follows;

[tex]Mean = n *p[/tex]

Where

[tex]n = 16[/tex] -- Sample Size

[tex]p = 22\%[/tex] -- Proportion

So:

[tex]Mean = n *p[/tex] becomes

[tex]Mean = 16 * 22\%[/tex]

Convert 22% to decimal

[tex]Mean = 16 * 0.22[/tex]

[tex]Mean = 3.52[/tex]

Hence, the mean is 3.52

Answer: 75%

Step-by-step explanation: First, you have to divide the numerator (6) by the denominator (8), which equals 0.75 in this case. Then you have to multiply the decimal (0.75) by 100. So you get the answer 75%.

Answer:

P(A | Y = 8) =  0.633

Step-by-step explanation:

It is really a simple and interesting question, as it involves the Poisson distribution and probability.

First of all, let's try to understand the problem statement clearly. It says that there are two process by which beams are made, namely A and B.

It further states that, beam made by process A has = 10 flaws per meter.

Beam made by process B has = 5 flaws per meter.

Finally, it says that from a yard containing equal numbers of process A and process B beans, one beam is randomly selected and 1 - meter of it is inspected. And they have found 8 flaws in it.

We now, have to find out the probability that the inspected beam is from process A.

For this,

Let's suppose, Y is no. of flaws

So,

P (Y=8|A) = [tex]\frac{e^{-10}. 10^{8} }{8!}[/tex]

where , e = Euler's Constant = 2.71828

P (Y=8|A) = 0.11

Similarly for process B

P (Y=8|B) = [tex]\frac{e^{-5}. 5^{8} }{8!}[/tex]

P (Y=8|B) = 0.06

As, we know from the problem statement that there are equal numbers of process A and process B beams.

So, the probability of A = Probability of B = 0.5

P(A) = 0.5

P(B) = 0.5

We need to find, P(A|Y=8) and for this we need to find the P(Y=8) first.

Using the law of total probability:

P(Y=8) =  P(Y = 8 |A) P(A) + P(Y = 8|B) P(B)

Plug in the values:

P(Y=8) = (0.11 x 0.5) + (0.06 x 0.5)

P(Y=8) = 0.088

Now, by applying Bayes Theorem, we can find the required probability:

P(A | Y = 8) = P(Y = 8 | A) P(A) / P(Y = 8)

8 flaws are found, the probability the inspected beam was fabricated using process A is :

P(A | Y = 8) = 0.11 x 0.5 / 0.088

P(A | Y = 8) =  0.633

Furthermore,

8 flaws are found, the probability the inspected beam was fabricated using process B is :

P(B | Y = 8) = 1-P(A | Y = 8)

P(B | Y = 8) = 1 - 0.633

P(B | Y = 8) = 0.367

Step-by-step explanation:

The required simplified value of the [f⁻¹(1/8)]' is 4 / 9. Option B is correct.

The method of determining the derivative of an implicit function by differentiating each term separately, expressing the derivative of the dependent variable as a symbol, and solving the resulting expression for the symbol.

Here,
Let f(x) = y
Given function,
y = [3x -1]²
The inverse of the above function is given as,
f⁻¹(x) = [∛x + 1]/3
Differentiate the above inverse function,
[f⁻¹(x)]' = 1/[9x²/³]
Substitute x = 1/8
[f⁻¹(1/8)]' = 1/[9(1/8)²/³]

[f⁻¹(1/8)]' = 4 / 9

Thus, the required simplified value of the [f⁻¹(1/8)]' is 4 / 9. Option B is correct.

Step-by-step explanation:

x²y = k, where k is a real constant.

When x = 3, y = 8.

Therefore k = (3²)(8) = 72.

The equation is x²y = 72 or y = 72/x².

Answer:

10(5+3)

Step-by-step explanation:

The required expression would be 10(5+3) which is written as a product of two factors and the correct answer would be option (D).

Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.

We have been given that expression as:

⇒ 50 + 30

We need to write 50 and 30 as the product of its prime factors,

50 = 5 × 5 × 2  and 30 = 2 × 3 × 5

So 50 + 30

⇒ 5 × 5 × 2 + 2 × 3 × 5

Common factor out, and we get

⇒ 5 × 2 (5 + 3)

⇒ 10(5 + 3)

Therefore,  the correct answer would be an option (D).

Hey there!

Basically the mean is the average of your given set that you have!

Here is your formula:

mean = SUM of each over your terms DIVIDED BY NUMBER of terms

“15, 8, 12, 14, 10,13”

SUM = addition

15 + 8 + 12 + 14 + 10 + 13

15 + 8 = 23

23 + 12 + 14 + 10 + 13

23 + 12 = 35

35 + 14 + 10 + 13

35 + 14 = 49

49 + 10 + 13

49 + 10 = 59

59 + 13 = 72

72 / NUMBER OF TERMS

Number of terms: 6

72 / 6 = 12
