Answer:

D. The company's chocolate bars weigh 3.2 ounces on average.

Step-by-step explanation:

We are given that  a company claims that its chocolate bars weigh 3.2 ounces on average.

The company took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.

Definition of 95% confidence level: 95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.

Thus by considering definition we can conclude that The company's chocolate bars weigh 3.2 ounces on average.

Thus Option D is correct.

D. The company's chocolate bars weigh 3.2 ounces on average.

SOMEONE HELP ME PLEASE I NEED HELP

Answer:

Rectangle: 6x4=24

Right triangles: 6x1/2=3

3x2=6

Step-by-step explanation:

If you separate the trapezoid into two triangles and a rectangle you can find the area of the rectangle (length x width) and then to find the area of both of the triangles on the sides you do (leg x leg /2) but since there are two you can multiply by two again (or just do leg x leg).

Hope that helps!

The quadrilateral shown is a rectangle. What is the measure of CE?
aalyn [17]

Answer:

|CE|=2

Step-by-step explanation:

The quadrilateral is shown in the attachment

Recall that the diagonals of a rectangle are congruent.

This implies that:

|AC|=|BD|

We substitute the expressions to get:

2x-6=5x-21

This is now a linear equation in one variable.

Group similar terms to get:

-6+21=5x-2x

Simplify to get:

15=3x

Divide both sides by 3 to get:

5=x

Recall again that the diagonals of a quadrilateral bisect each other.

|CE|=\frac{1}{2}|AC|

|CE|=\frac{1}{2}|2x-6|

Plug x=5

|CE|=\frac{1}{2}|2*5-6| =10-6=\frac{1}{2}*4=2
