The odometer readings on a random sample of identicle model sports cars are normally distributed with mean of 120000 miles and a

Nat2105 [25]

Answer:

We are given that random sample of identical model sports cars are normally distributed with mean of 120000 miles and standard deviation of 30000 miles.

$\mu=120000, \sigma = 30000$

We have to find approximately how many sports cars will have less than 150000 miles on the odometer.

We will first find the z-score for 150000.

$z=\frac{x-\mu}{\sigma}$

$=\frac{150000-120000}{30000}$

$=1$

Now using the standard normal table, we have:

$P(z$

Now there will be approximately $0.8413 \times 6000=5047.8 \approx 5048$ sport cars will have less than 150000 miles on the odometer.

Find the balance in an account with $4,250 principal earning 3% interest compounded quarterly after 12 years. Round your answer

Marat540 [252]

X = principle ( 1 + rate/compound rate) ^ years

x = 4250[1+(0.3/4)]^12
x = 4250(1+0.075)^12
x = 4250(1.075)^12
x = 4250(2.38178)
x = $10,122.23
