Answer:

Exponents seem pretty straightforward, right? Raise a number to the power of 1 means you have one of that number, raise to the power of 2 means you have two of the number multiplied together, power 3 means three of the number multiplied together and so on.

Find x when y=6 in the literal equation 5x+4y=39<br><br>A. 12.6<br>B. 15<br>C. 2.25<br>D. 3

muminat

Answer:

y=6

then,

5x+4y=39---> plug y in to the function

5x+4(6)=39

5x+ 24=39

5x= 39-24

5x= 15

x= 15/5

x= 3

So, the value of x when y=6 in that function is 3 (D)

Susan plans to rent a bike in New Orleans to tour the city. The cost of the rental is $20 per day. The cost of a helmet is $7 fo

krek1111 [17]

Answer:

No, she does not.

Step-by-step explanation:

Using the words here, we can create the expression $20d + 7$ where d is the number of days.

We can now substitute 15 in as d, to see how much this will cost.

$20\cdot15 + 7\\\\300+7\\\\307$

So the total cost will be $307.

Since $307 is more than $250, she does not have enough money.

Hope this helped!

James Desreumaux, VP of Human Resources of American First Banks (AFB), is reviewing the employee training programs of AFB banks.

BartSMP [9]

Answer: (24.02,25.98)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given : Sample size : n= 100

Sample mean : $\overline{x}=25\text{ hours}$

Standard deviation : $\sigma=5\text{ hours}$

Significance level : $\alpha: 1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

The confidence interval for population mean is given by :-

$\overline{x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=25\pm(1.96)\dfrac{5}{\sqrt{100}}\\\\=25\pm0.98\\\\=(25-0.98,\ 25+0.98)=(24.02,25.98)$

Hence, the 95% confidence interval for the population mean of training times is (24.02, 25.98).
