Answer:

The probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Step-by-step explanation:

Mean = \mu = 45

Population standard deviation =\sigma = 6

Sample size = n =25

Sample mean = \bar{x} = 52

We are supposed to find  the probability of observing a sample mean of x = 52 or greater from a sample size of 25 i.e.P(x\geq 52)

Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}\\Z=\frac{52-45}{\frac{6}{\sqrt{25}}}

Z=5.83

P(Z<52)=0.9999974

P(Z\geq 52)=1-P(z

Hence  the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

nikklg [1K]

Answer:

61.15 m

Step-by-step explanation:

From trigonometry :

Tan x = opposite / Adjacent

x = 28°

Tan 28 = distance from base to fire / height

0.5317094 = distance from base to fire / 115

distance from base to fire = 115 * 0.5317094

distance from base to fire = 61.15 m
