Answer:

volume = 10m^3

Step-by-step explanation:

This shape is called a rectangular prism. The formula for finding the volume of this prism is: volume = L * W * H

All you do is plug the values into the formula.

The length is 2m

The width is 1m

the height is 5m

Volume = (2m)(1m)(5m)

Volume = 10m^3

How many gallons of pure water should be evaporated from 160 gallons of a solution containing 12% salt so that the remaining sol
algol [13]

Answer:  It is asking the amount of pure water.

Amount of  pure water evaporated is 64 gallons .

Step-by-step explanation:

Let x gallons  be the amount of evaporated water.

Amount of water before evaporation

      =12% of 160

      = 0.12(160) = 19.2 gallons .......(1)

amount of solution after x gallon water evaporation  = 160-x

amount of salt in 160-x  solution =   20% of 160-x

                                                     =0.2 (160-x) ........... (2)

Since amount of salt will be same before and after evaporation

  from (1 )  and (2)

0.2(160-x) = 19.2

32-0.2x = 19.2

  -0.2x = 19.2-32

 -0.2x = -12.8

       x = -12.8/(-0.2)

       x   = 64  gallons

HighTech Inc. randomly tests its employees about company policies. Last year in the 560 random tests conducted, 26 employees fai
Tanzania [10]

Answer:

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

560 random tests conducted, 26 employees failed the test. This means that n = 560, \pi = \frac{26}{560} = 0.046

98% confidence level

So \alpha = 0.02, z is the value of Z that has a pvalue of 1 - \frac{0.02}{2} = 0.99, so Z = 2.33.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 - 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.025

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 + 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.067

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).
