Suppose you want to save in order to purchase a new boat. Take the APR to be 6.0%.

Rama09 [41]

Answer:

Amount deposit each month = $365.26

Step-by-step explanation:

Given:

Amount deposit = $15,000

Rate = 6% = 6% / 12 = 0.005

Number of time = 3 x 12 = 36

Find:

Amount deposit each month

Computation:

Amount deposit each month = [(15,000) x 0.005]/[(1.005){(1.005)³⁶-1}]

Amount deposit each month = $365.26

The time it takes to completely tune an engine of an automobile follows an exponential distribution with a mean of 40 minutes.

Mazyrski [523]

Answer: a. P (x<30) = 0.5276

b. P (30<x<35) = 0.0555

Step-by-step explanation: An exponential distribution is a distribution of time in which events happens at a constant average rate.

The rate is calculated as

$\lambda=\frac{1}{\mu}$

with μ as the mean.

The probability density distribution for this type of distribution is

$f(x)=\lambda e^{-\lambda x}$

And probability is calculated as

$P(X$

For tuning of an engine, the rate is

$\lambda=\frac{1}{40}$

λ = 0.025

a. Probability of less than 30 minutes:

$P(X$

P (X < 30) = 0.5276

Probability of tuning in 30 minutes or less is 52.76%.

b. Probability of between 30 and 35 can be described as

$P(30$

$P(X$

P (X < 35) = 0.5831

P (X < 30) = 0.5276

Then:

$P(30$

P (30 < X < 35) = 0.0555

Probability of tuning an engine between 30 and 35 minutes is 5.55%.

Find the area of this circle. Use 3.14 for a 11 ft The area of the circle is about ft2. (Round to the nearest hundredth as neede

Nutka1998 [239]

Answer:

Area of circle is 379.94 feet²

Step-by-step explanation:

Given: 

Radius of circle = 11 feet

To Find: 

Area of circle.

Solution:

Here given that radius of circle is 11 feet. Using the formula of area of circle we will get the required area of circle

Area of circle = πr²

On substituting the required values: 

Area = 3.14 × (11)²

Area = 3.14 × 121

Area = 379.94 feet²

Hence,

Area of circle is 379.94 feet²
