The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 2135 miles, with a variance
stiv31 [10]

Answer:

0.36878

Step-by-step explanation:

Given that:

Mean number of miles (m) = 2135 miles

Variance = 145924

Sample size (n) = 40

Standard deviation (s) = √variance = √145924 = 382

probability that the mean of a sample of 40 cars would differ from the population mean by less than 29 miles

P( 2135 - 29 < z < 2135 + 29)

Z = (x - m) / s /√n

Z = [(2106 - 2135) / 382 / √40] < z < [(2164 - 2135) / 382 / √40]

Z = (- 29 / 60.399503) < z < (29 / 60.399503)

Z = - 0.4801364 < z < 0.4801364

P(Z < - 0.48) = 0.31561

P(Z < - 0.48) = 0.68439

P(- 0.480 < z < 0.480) = 0.68439 - 0.31561 = 0.36878

= 0.36878

A population p of migrating butterflies changes over time it is represented by the equation p=100,000*4/5 where w is the number
Trava [24]

Given that,

A population p of migrating butterflies changes over time it is represented by the equation

p=100,000\times (\dfrac{4}{5})^w Where w is number of weeks.

To find,

The population after 2 weeks.

Solution,

We have,

p=100,000\times (\dfrac{4}{5})^w

Put w = 2 in the above equation.

p=100,000\times (\dfrac{4}{5})^2\\\\=100,000\times \dfrac{16}{25}\\\\=64000

So, the population after 2 weeks is 64000 .
