Answer:
The scale factor is 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional , and this ratio is called the scale factor
Let
z----> the scale factor
x ----> the corresponding side of the resulting image
y-----> the corresponding side of the first rectangle

we have


substitute

Calculate the z-score of the given by the equation,
z-score = (x - m)/s
where x is the data point, m is the mean, and s is the standard deviation. Substituting the known values,
z-score = (11 - 8)/ 3 = 1
This translates to 0.84.
ANSWER: 0.84.
Answer:
its B
Step-by-step explanation:
first calculate the perimeter then the area of the base
perimeter 15
area of base 10.8250
then mutiply by the hight
(1/2x15x4.33)+10.8250=43.3000000
The midpoint between points A and B is :
M = ( 1 , −4 )
