Eric has another cube with edge lengths of 8 inches each He said the edge

Trava [24]

Answer:

nope

Step-by-step explanation:

Volume of a cube = a^3

1st cube with edge of 8:

V= 8^3

V= 512 cubic inches

2nd cube

V = (2 X 8)^3

V= 4096 cubic inches

If we multiply by 2 the 1st volume it is equal to 1024 cubic inches only, while the volume ogmf the 2nd cube is 4096

If men's heights are normally distributed with mean 68 and standard deviation 3.1 inches, and women's heights are normally distr

stira [4]

Answer:

the probability that the woman is taller than the man is 0.1423

Step-by-step explanation:

Given that :

the men's heights are normally distributed with mean $\mu$ 68

standard deviation $\sigma$ = 3.1

And

the women's heights are normally distributed with mean $\mu$ 65

standard deviation $\sigma$ = 2.8

We are to find the probability that the woman is taller than the man.

For woman now:

mean $\mu$ = 65

standard deviation $\sigma$ = 2.8

$P(x > 68 ) = 1 - p( x< 68)$

$\\ 1 -p \ P[(x - \mu ) / \sigma < (68-25)/ 2.8]$

= 1-P (z , 1.07)

Using z table,

= 1 - 0.8577

= 0.1423

Thus, the probability that the woman is taller than the man is 0.1423
