Answer:

F(8,6)

Step-by-step explanation:

(x₁,x₂) --> E (-7, 2)

F(x₂,y₂)

Midpoint M(0.5 , 4)

Midpoint = $(\frac{x_{1}+x_{2}}{2},\frac{+y_{1}+y_{2}}{2})$

$(\frac{-7+x_{2}}{2},\frac{2+y_{2}}{2}) = (0.5, 4)\\\\$

Compare x,coordinates and y-coordinates,

$\frac{-7+x_{2}}{2}= 0.5 \ ; \ \frac{2+y_{2}}{2}=4\\\\$

-7 + x₂ = 0.5*2 ; 2+y₂ = 4*2

-7+ x₂ = 1 ; 2 +y₂ = 8

x₂ = 1+ 7 ; y₂ = 8 - 2

x₂ = 8 ; y₂ = 6

F(8,6)

A shipment of beach balls with a mean diameter of 28 cm and a standard deviation of 1.3 cm is normally distributed. By how many

dlinn [17]

Answer: D.) 3

Step-by-step explanation:

Given: Mean diameter: $\mu=28\ cm$

Standard deviation: $\sigma=1.3\ cm$

The required number of standard deviations is given by :-

$z=\frac{X-\mu}{\sigma}\\\\\Rightarrow\ z=\frac{31.9-28}{1.3}\\\\\Rightarrow\ z==3$

Hence, a beach ball with a diameter of 31.9 cm is 3 standard deviations differ from the mean.
