Answer:

15.6m

Step-by-step explanation:

FE is the hypotenuse, and we know the leg opposite of the angle, so we have to use the sin

sin = opposite/hypotenuse

hypotenuse * sin = opposite

hypotenuse = opposite / sin

FE = 10/0,64... = 15.6

Alja [10]

Answer: 554

Step-by-step explanation:

Formula we use to find the sample size :

$n=(\dfrac{z_{\alpha/2}\cdot\sigma}{E})^2$

Given : Standard deviation : $\sigma=3\ hour$

Margin of error : E=one quarter hour = 0.25 hour

Two-tailed , Critical value use for 0.95 degree of confidence: $z_{\alpha/2}=1.96$

i.e. $n=(\dfrac{(1.96)\cdot(3)}{0.25})^2=553.1904\approx554$

Hence, the required sample size = 554

i.e. 554 executives should be surveyed.
