There are many possible solutions to this problem.

Area (A) = Length (L) x width (w)

200 = L x w (any two numbers whose product is 200 is acceptable)

I am going to choose L=20 and w=10, then A = 20 x 10 = 200

Perimeter (P) = 2L + 2w

= 2(20) + 2(10)

= 40 + 20

= 60

Answer: one possible solution is L=20, w=10, P=60

Dvinal [7]
This is quite simple. We will first add the amount of miles walked together.
3.25+5.5=8.75
Then we will divide 175 by the number of miles walked which in this case is 8.75.
Then we get 20 which is the amount of money that his parents donated for every mile that he walked.

The standard deviation for actuary salaries has a standard deviation of $36,730 . You collect a simple random sample of n=36 sal
Yanka [14]

Using the z-distribution, it is found that the lower limit of the 95% confidence interval is of $99,002.

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

\overline{x} \pm z\frac{\sigma}{\sqrt{n}}

In which:

  • \overline{x} is the sample mean.
  • z is the critical value.
  • n is the sample size.
  • \sigma is the standard deviation for the population.

In this problem, we have a 95% confidence level, hence\alpha = 0.95, z is the value of Z that has a p-value of \frac{1+0.95}{2} = 0.975, so the critical value is z = 1.96.

The other parameters are given as follows:

\overline{x} = 111000, \sigma = 36730, n = 36

Hence, the lower bound of the interval is:

\overline{x} - z\frac{\sigma}{\sqrt{n}} = 111000 - 1.96\frac{36730}{\sqrt{36}} = 99002

The lower limit of the 95% confidence interval is of $99,002.

Y=x+2<br> x-y=2<br> What is the solution
Alisiya [41]

Answer:

No solutions.

Step-by-step explanation:

x - y = 2   <Start with an equation

x - (x + 2) = 2   <Plug in the given y value and solve for x

x - x - 2 = 2   <Combine like terms

0 - 2 = 2   <There are no values of x

No solutions.
