Suppose that 8% of all cars produced at Plant A have a certain defect, and 5% of all cars produced at Plant B have this defect. A quality control manager takes separate random samples of 150 cars from each plant. The manager will then look at the difference (A-B) between the proportions of cars with the defect in each sample.

What will be the shape of the sampling distribution of the difference in sample proportions, and why?

Choose 1 answer:

A. Approximately normal, because we expect 12 defective and 138 defect-free cars from Plant A, and 15 and 135 from Plant B, and all of these counts are at least 10.

B. Approximately normal, because we expect 16 defective and 134 defect-free cars from Plant A, and 10 and 140 from Plant B, and all of these counts are at least 10.

C. Not normal, because we expect fewer than 10 defective cars in Plant A.

D. Not normal, because we expect fewer than 10 defective cars in Plant B.

Answers

Combine like terms

3n = -27
Divide by 3
n = -27/3 (u can simplify)

5n+2n+6=4n-21 group like terms on left side

7n+6=4n-21subtract 6 from both sides

7n=4n-27 subtract 4n from both sides

3n=27 divide both sides by 3

Aldo made 12 of 18 baskets during the first half of the basketball game. What is the experimental probability that he will make the next basket?

Answers

Answer:

I think that the answer is 66%

Step-by-step explanation:

12/18

divide both numbers by 6

2/3

turn this fraction into a percentage

66%

The experimental probability that he will make the next basket will be 66.66%.

What is Probability?

The formula to calculate the probability of occurrence of an event 'A' can be written as -  

P(A)  = n(A)/n(S)  

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes.

Given is Aldo made 12 of 18 baskets during the first half of the basketball game.

If Aldo made 12 of 18 baskets during the first half of the basketball game, then we can write the experimental probability as -

P(E) = 12/18 = 2/3

P(E) = 2/3 x 100 = 66.66%

Hence, the experimental probability that he will make the next basket will be 66.66%.

The proportion is given by the equation c = pg where the value of p is

p = 0.75

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as p

Now , the equation will be

Jaiden mixed 6 cups chocolate chips with 8 cups of granola to make trail mix

So , for 6 cups chocolate chips = p x 8 cups of granola

So , the proportion will be

Substituting the values in the equation , we get

6 = p x 8

Divide by 8 on both sides of the equation , we get

p = 6/8

On simplifying the equation , we get

p = 0.75

Therefore , the value of p is 0.75

Hence , the proportion equation is c = 0.75g

Colton's mini-van is depreciating at a rate of 5.5% per year. He paid $22,250 for it in 2019. How much will the car be worth in 2025 to nearest cent?

Answers

Answer:

$1584.2

Step-by-step explanation:

Given data

R= 5.5%

T= 2025-- 2019=  6years

P=  $22,25

Let us apply Compound interest formula

A=P(1-r)^r ------------Note negative for  depreciation

A= 2225(1-0.055)^6

A= 2225(0.945)^6

A= 2225*0.712

A=$1584.2

Triangle inequality

Answers

Answer:

DF

EF

DE

Step-by-step explanation:

First, we need to figure out the third angle.

Angles in a triangle add up to 180, so

180 = 61 + 59 + DEF

DEF = 180 - (61 + 59) = 180 - 120 = 60

In a triangle, the smallest angle is always opposite the shortest side, and the largest angle opposite the longest.

The three angles are 61, 60, and 59.

Since DEF(61) is the largest, DF is the longest.

Next is EDF(60), so EF is the next.

Finally, DFE(59) is the smallest angle, so DE is the shortest.

DF, EF, DE
