1. I think the distance is 5 miles because the y-axis points for both coordinates are the same, and the difference between the x-axis points is 5; 9-4=5

2.
a. (3, 1) and (3, 5) because if you remove the -, it will be (3, 1) and (3, 5).
b. (-2, -6) , (-2, -10) , (2, 6) , and (2, 10).

b. All you have to do is get 2 points that are negative, and for the other 2 coordinates, remove the negative sign.

Hope this helped☺☺

Answer:

At the 95% confidence level, management should not conclude that the percentage of rework for electrical components is lower than the rate of 12% for non-electrical components, since the upper bound of the confidene interval, which is 0.1339, is higher than 0.12.

Step-by-step explanation:

To reach a conclusion, we have to observe the confidence interval.

Should management conclude that the percentage of rework for electrical components is lower than the rate of 12% for non-electrical components?

Is the upper bound of the confidence interval lower than 12% = 0.12?

If yes, it should conclude that this percentage is lower.

Otherwise, it cannot conclude.

Confidence interval:

0.0758 to 0.1339

0.1339 is higher than 0.12.

So.

At the 95% confidence level, management should not conclude that the percentage of rework for electrical components is lower than the rate of 12% for non-electrical components, since the upper bound of the confidene interval, which is 0.1339, is higher than 0.12.

Consider the polynomial p(x)=8x3+12x2+2x+3.
Ivahew [28]

A: (4x^2+1)(2x+3)

B: grouping

Step-by-step explanation:

We are given the polynomial: p(x)=8x^3+12x^2+2x+3

Part A: What is the correct factorization of p(x)=8x^3+12x^2+2x+3 over the integers?

We need to factorize the term p(x)=8x^3+12x^2+2x+3

Factorizing by grouping:

p(x)=8x^3+12x^2+2x+3

p(x)=(8x^3+12x^2)+(2x+3)

p(x)=4x^2(2x+3)+1(2x+3)

p(x)=(4x^2+1)(2x+3)

So, factors of the term p(x)=8x^3+12x^2+2x+3 are p(x)=(4x^2+1)(2x+3)

Part B: What method is used to factor p(x)=8x3+12x2+2x+3?

The method used to factor the given polynomial is grouping.

We group the terms and then find the common terms in that specific group

So, the answers are:

A: (4x^2+1)(2x+3)

B: grouping
