Answer: The answer would be B) 9% Decrease!

275 - 250 = 25.

25/275 = 0.0909090909

0.0909090909 x 100 = 9.09090909091

Finally you'd round it to 9%.

Therefore there was a 9% decrease in the amount of large pizzas.

Hope this helps (: Stay safe.

Help can u answer this
umka21 [38]

Answer:

c) 82

d) - 11

g)27

h)1000

k)11

l) 8

Step-by-step explanation:

{9}^{2}  + 1  \\  = (9 \times 9) + 1 \\  = 81 + 1 \\  = 82

{6}^{2}  -  {5}^{2}  \\  = (6 \times 6) - (5 \times 5) \\  = 36 - 25 \\  =  - 11

(1 + 2 {)}^{3}  \\  =  {3}^{3}  \\  = 3 \times 3  \times 3\\  = 27

(2 + 8 {)}^{3}  \\  =  {10}^{3}  \\  = (10 \times 10 \times 10) \\  = 1000

\sqrt{4}  +  {3}^{2}  \\  = 2 +  {3}^{2}  \\  = 2 + (3 \times 3) \\  = 2 + 9 \\  = 11

2 \times 5 -  \sqrt{4}  \\  = 10 -  \sqrt{4}  \\  = 10 - 2 \\  = 8

The height of a women in the united states are normally distributed with a mean of 64 inches and a standard deviation of 2.75 in
Tatiana [17]

Answer:

The area under the curve that represents the percent of women whose heights are at least 64 inches is 0.5.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X, or the area under the curve representing values that are lower than x. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X, which is the same as the area under the curve representing values that are higher than x.

In this problem, we have that:

\mu = 64, \sigma = 2.75

Find the area under the curve that represents the percent of women whose heights are at least 64 inches.

This is 1 subtracted by the pvalue of Z when X = 64.

Z = \frac{X - \mu}{\sigma}

Z = \frac{64 - 64}{2.75}

Z = 0

Z = 0 has a pvalue of 0.5.

1 - 0.5 = 0.5

The area under the curve that represents the percent of women whose heights are at least 64 inches is 0.5.

Someone helppp! This is due the day after tomorrow!!
PilotLPTM [1.2K]

Step-by-step explanation:

Given

(2x + 3 )² - (2x + 3) (x - 5)

= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))

= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )

= 4x² + 6x + 9 - 2x² + 10x - 3x + 15

= 2x² + 13x + 24

Hope it will help :)

Which shows how to determine the volume of the pyramid?<br><br>​
Fudgin [204]

Answer:

d would be correct

Step-by-step explanation:

A pyramid is a polyhedron formed by connecting a polygonal base and an a a p e x. The basic formula for pyramid volume is the same as for a cone: volume = (1/3) times  base area times height, where height is the height from the base to the a p e x. That formula is working for any type of base polygon and oblique and right pyramids.
