If p||q then, m∠1=m∠3

9x = 117
x = 117/9
x = 13

Answer:

answer is 26.6%

Step-by-step explanation:

i first converted the fraction "40/150" to a decimal by dividing 40 by 150

40 divided by 150 is .26 (rounded)

and then i did .26 times 100

which gave me 26.6

The distribution of the amount of a customer’s purchase at a convenience store is approximately normal, with mean $15.50 and sta

viktelen [127]

Answer:

0.42 is closest to the proportion of customer purchase amounts between $14.00 and $16.00

Step-by-step explanation:

Mean = $\mu = 15.50$

Standard deviation = $\sigma = 1.72$

We are supposed to find the proportion of customer purchase amounts between $14.00 and $16.00

P(14<x<16)

Formula : $z=\frac{x-\mu}{\sigma}$

At x = 14

$z=\frac{14-15.50}{1.72}$

$z=-0.8720$

Refer the z table for p value

P(x<14)=0.1922

At x = 16

$z=\frac{16-15.50}{1.72}$

$z=0.290$

Refer the z table for p value

P(x<16)=0.6141

P(14<x<16)=P(x<16)-P(x<14)=0.6141-0.1922=0.42

So, Option C is true

Hence 0.42 is closest to the proportion of customer purchase amounts between $14.00 and $16.00

Question

What is the height of the shape formed by the sectors shown below? A circle is cut into 8 equal sections. The sections are arranged into the shape of a parallelogram with a base of pi r and height of question mark.

a. r

b. d

c. pi times r

d Pi times d

Answer:

a. r

Step-by-step explanation:

In the diagram shown, we can see the sections are divided into 8 and each has a radius of r

The 8 sections from the circle is used to form the a parallelogram.

If we take a look at the diagram of the parallelogram closely, we can see definitely that it still showing the divided 8 equal sections using to form it.

Hence, the height of the parallelogram = the radius of the circle.

Therefore, height of the shape formed by the sectors is r
