The annual increase in height of cedar trees is believed to be distributed uniformly between five and ten inches. Find the proba

gayaneshka [121]

Answer: 0.6000

Step-by-step explanation:

Given : The annual increase in height of cedar trees is believed to be distributed uniformly between 5 and 10 inches.

Then the probability density function:-

$f(x)=\dfrac{1}{10-5}=\dfrac{1}{5}$

Then , the probability that a randomly selected cedar tree will grow less than 8 inches in a given year will be :-

$P(x\leq8)=\int^8_5f(x)\ dx\\\\=\int^8_5(\dfrac{1}{5})\ dx\\\\=\dfrac{1}{5}[x]^8_5\\\\=\dfrac{1}{5}\times(8-5)=\dfrac{3}{5}=0.6000$

Hence, the probability that a randomly selected cedar tree will grow less than 8 inches in a given year =0.6000

Step-by-step explanation:

According to PEMDAS, the Parentheses comes first so we have to solve what is in the Parentheses first.

(20 - 2) = 18

$\frac{1}{3}$ (18)

So now we divide 18 by $\frac{1}{3}$ = 6
