Evaluate the expression. 5^2. what is the value of the expression?​
vovangra [49]

Answer:

25

Step-by-step explanation:

Any numbers to the 2nd powered are always squared. Whenever you are given an exponent, the base is the number that you multiply, and the power is one more than how many times you multiply the base number together. In this case, you multiply five by itself once to get 25 as your answer.

Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of 2,250,000 and a mean
Svet_ta [14]

Answer: 0.1357

Step-by-step explanation:

Given : Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of \sigma^2=2,250,000 and a mean life span of \mu=13,000 hours.

Here , \sigma=\sqrt{2250000}=1500

Let x represents  the life span of a monitor.

Then , the probability that the life span of the monitor will be more than 14,650 hours will be :-

P(x>14650)=P(\dfrac{x-\mu}{\sigma}>\dfrac{14650-13000}{1500})\\\\=P(z>1.1)=1-P(z\leq1.1)\ \ [\because\ P(Z>z)=1-P(Z\leq z)]\\\\=1-0.8643339=0.1356661\approx0.1357

Hence, the probability that the life span of the monitor will be more than 14,650 hours = 0.1357
