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.
Answer: log(x)+log(y)
Step-by-step explanation:
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:
In which:
is the sample mean.
is the standard deviation for the population.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.96.
The other parameters are given as follows:
Hence, the lower bound of the interval is:
The lower limit of the 95% confidence interval is of $99,002.

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
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.
