Combine powers. 2^5/2^3 = 2^(5 - 3):

2^(5 - 3)

Ket [755]

Answer:

The probability that a randomly chosen light bulb will last less than 900 hours is 0.1587.

Step-by-step explanation:

The life span of these light bulbs is normally distributed with a mean of 1000 hours and a standard deviation of 100 hours

Mean = \mu = 1000 hours

Standard deviation =\sigma = 100 hours

We are supposed to find the probability that a randomly chosen light bulb will last less than 900 hours.i.e. P(x<900)

So, Z=\frac{x-\mu}{\sigma}

Z=\frac{900-1000}{100}

Z=-1

P(x<900)=P(z<-1)=0.1587

Hence the probability that a randomly chosen light bulb will last less than 900 hours is 0.1587.

Nimfa-mama [501]
Paybeginning $1,032 - $150 = $882.56* 1.00938 = $ 890.84
Pay end $1,032.56 * 1.00938 = $1042.25- $150 = $892.25

The difference is in interest in the first month 892.25−890.25=2


Note: 11.25 / 12 = 0.00938 interest per month

Dafna11 [192]
You would do 10.5×8 since it is the area of a rectangle. That would get you 84.

You then do 84×1.25 since there is 84 square feet. That would get you 105.

It would cost her $105.
