Michael is 17 years older than John. In 4 years, the sum of there ages will be 49. Find Michaels present age.
Crank
Answer:

29

Explanation:

Let John be x years old.

Michael is <span>x+17</span> years old.

In four years time, the sum of their ages will be 49:

<span>x+x+17+2<span>(4)</span>=49</span>

<span>2x=24</span>

<span>x=12</span>

So Michael is <span>12+17=29</span> years old now.

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.

A toaster oven usually sells for $68. If the toaster oven is 20% off, and sales tax is 6%, what is the total price of the toaste
sertanlavr [38]

Answer:


Step-by-step explanation:


20% discount is 1/5 x 68 = 13.60


So pre-tax price is 68 - 13.60 = 54.40


Add sales tax:


54.40 x 1.06 = 57.66


so the answer is C

Hurry When solving a system of equations, Jared found y = x 10 for one equation and substituted x 10 for y in the other equation
Aloiza [94]
I can say that Jared and Nicole are correct because they manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. They can also write the equation as x as a function of y and substitute it to x in the other equation and solve for y. For both solution, they will still obtain the same answers.
