Which graph shows a dilation of the rectangle with a scale factor of 2?

the first one is part of the question not an answer iption

The graph that shows the dilation of the rectangle in the attached figure

Step-by-step explanation:

we know that

A dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

In this problem we have that the scale factor is equal to 2

Remember that

If a scale factor is greater than 1, then the dilation is a enlargement

To find out the dimensions of the dilated figure multiply the original dimensions by the scale factor

The original dimensions of rectangle are

The dimensions of the dilated rectangle are

therefore

The graph that shows the dilation of the rectangle in the attached figure

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
