valina [46]

Answer:

444 :) (angel number, haha)

Step-by-step explanation:

it needs 74 times 2 mm which is 148 I think, which will also be the length since 148 is 2 times more than 74

so it's : 74 + 74 + 148 + 148 which is basically just 148 times three, so the answer is 444!

Adult male heights are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The average basketbal

sweet-ann [11.9K]

Answer: First Option is correct.

Step-by-step explanation:

Since we have given that

Mean $(\mu)$ = 70 inches

Standard deviation $(\sigma)$ = 3 inches

Average basket ball player $(\bar{X})$ = 79 inches

Since it is normally distributed assume with 5% significance .

So, it becomes,

$Z>\frac{\bar{X}-\mu}{\sigma}\\\\Z>\frac{79-70}{3}\\\\Z>\frac{9}{3}\\\\Z>3\\\\\therefore\ P(Z>3)=1-0.9987=0.0013$

At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .

Hence, First Option is correct.
