Answer:

**Answer:**

538 books should be tested.

**Step-by-step explanation:**

We have that to **find **our level, that is the subtraction of 1 by the confidence interval divided by 2. So:

**Now**, we have to find z in the Ztable as such z has a pvalue of .

So it is z with a pvalue of , so

**Now**, find the margin of error M as such

In which is the standard deviation of the population and n is the size of the sample.

**How many books should be tested to estimate the average force required to break the binding to within 0.08 lb with 99% confidence?**

n books should be tested.

n is found when

We have that

Rounding up

538 books should be tested.

2) Predict the number of tips that would be collected if 100 costumers were served at the restaurant on a given day. Explain your reasoning.

3)EXPLAIN how to use the regression calculator to make a reasonable prediction given a data table

(I don't know how to attach more than 1 picture by the way )

**Answer:**

1) y = 1.8741176487x + 3.655964863

2) About $191 using the equation, about $180 or more using the data you are given.

3) I can use the regression calculator by using the largest number of customers you have in the data set and lowest number of customers and compare them to see if the numbers are in ascending or descending order.

I think the answer is 30.

the anwser is 34 because 5 and up would round up

**Answer:**

1 cup of blue paint required 5 cups of yellow paints

**Step-by-step explanation:**

**Given**

2 cups of blue = 10 cups of yellow

**Required**

Determine the number of cups of yellow for 1 cup of blue paint

**The given parameter shows a linear relationship between paints of blue and paints of yellow**

**We have:**

2 cups of blue = 10 cups of yellow

**Multiply both sides by 0.5**

0.5* 2 cups of blue = 0.5* 10 cups of yellow

1 cup of blue = 5 cups of yellow

**Hence;**

*1 cup of blue paint required 5 cups of yellow paints*

**Answer:**

y" = -24 / y³

**Step-by-step explanation:**

6x² + y² = 4

Take the derivative of both sides with respect to x.

12x + 2y y' = 0

Again, take the derivative of both sides with respect to x.

12 + 2y y" + y' (2y') = 0

12 + 2y y" + 2(y')² = 0

Solve for y' in the first equation.

2y y' = -12x

y' = -6x/y

Substitute and solve for y":

12 + 2y y" + 2(-6x/y)² = 0

12 + 2y y" + 2(36x²/y²) = 0

12 + 2y y" + 72x²/y² = 0

6y² + y³ y" + 36x² = 0

y³ y" = -36x² − 6y²

y" = (-36x² − 6y²) / y³

Solve for y² in the original equation and substitute:

y² = 4 − 6x²

y" = (-36x² − 6(4 − 6x²)) / y³

y" = (-36x² − 24 + 36x²) / y³

y" = -24 / y³
