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

An initial amount of 250 grows at a rate of 10% every year. Write an

Bingel [31]

Answer:

10% of 250 = 25.

When getting an increase, (using ^ for this example) add 25 to 250, getting 275. That's one increase of 10%. For an increase of 5 years (x = 5) divide 250/10=25, then multiply 25x5=125. That is the increase number. Add 125+250=375. Y=375

X = 5, Y = 375
