B.the circumference of C is pi*r
C: the circumference of C is 2pi*r
D. One quarter of the circle has length (pi*r)/4
E. One quarter of the circle has length(pi*r)/2

Answers

Answer:

A and C and E are correct

Step-by-step explanation:

Circumference = 2*pi*r

C is a circle with a radius r. The correct statements are; A. The diameter of C is 2r , C: The circumference of C is 2pi*r, E. One-quarter of the circle has a length(pi*r)/2.

What is the area of the circle?

Supposing that a considered circle has its radius of 'r' units.

Then, its area and circumference are given as:

[tex]Area = \pi r^2 \: \rm unit^2\\ \\Circumference = 2\pi r \: \rm units[/tex]

The radius of a circle is half of its diameter.

Therefore, the correct statements are;

A. The diameter of C is 2r

C: The circumference of C is 2pi*r

E. One-quarter of the circle has a length(pi*r)/2

The weights of baskets of strawberries are normally distributed with a mean of 3.8 ounces and a standard deviation of 1.1 ounces. One grocery store advertises that the weight of their strawberries is in the 97.5th percentile. How many ounces do their strawberries weigh?
A 3.8 ounces
B 4.9 ounces
C 6 ounces
D 7.1 ounces

Answers

Answer:

6 ounces

Step-by-step explanation:

this one is mainly elimination. 3.8 and 4.9 cant be because they're too close to the mean. and 7.1 is too far. you can also use z-score. the z score of .975 is 1.96 we can plug that into out formula so

1.96=(x-3.8)/1.1

multiply both sides by 1.1 and then add 3.8

you can also use scientific calculator.

second vars, 3, the area is your percent so .975, the u is mean so 3.8, the o is standard deviation so 1.1

Amanda financed a new living room set at the furniture store for $2,700. The store offered no interest for 6 months or 20 percent annually if the balance was not paid in full prior to the end of the interest free period. How much interest will she need to pay if she lets the account go for 6 months and 1 day before paying the bill?

Answers

Answer:

She will need to pay $269.36 in interest if she lets the account go for 6 months and 1 day before paying the bill.

Step-by-step explanation:

Given that Amanda financed a new living room set at the furniture store for $ 2,700, and the store offered no interest for 6 months or 20 percent annually if the balance was not paid in full prior to the end of the interest free period, to determine how much interest will she need to pay if she lets the account go for 6 months and 1 day before paying the bill, the following calculation must be performed:

((2,700 x 0.2) / 365) x 182 = X

(540/365) x 182 = X

1.48 x 182 = X

269.36 = X

Therefore, she will need to pay $ 269.36 in interest if she lets the account go for 6 months and 1 day before paying the bill.
