You sell 200 laptops per month at $499 per laptop. You sell 350 smartphones per month at $399 per phone. Which
tatuchka [14]

Answer:

B) Smartphones

Step-by-step explanation:

In order to answer this question we need to find the total revenue for the laptops and smartphones.

Let's start with the laptops.

Given:

  • 200 laptops/month
  • $499 per laptop

To find the total revenue of all these laptops we need to multiply 200 by 499.

(200) *(499) = 99,800

Therefore, the total revenue of the laptops alone is $99,800.

Now, let's do the smartphones.

Given:

  • 350 smartphones/month
  • $399 per smartphone

To find the total revenue of all these smartphones we need to multiply 350 by 399.

(350) * (399) = 139,650

Therefore, the total revenue of the smartphones alone is $139,650.

Comparing the two revenues we see that the smartphones generate more sales in dollars.

Hope this helps!

A random sample of 121 students from the University of Oklahoma had a sample mean ACT score of 23.4 with a sample standard devia
Grace [21]

Answer:

(22.74,24.06) is the required 95% confidence interval for the population mean ACT score of University of Oklahoma students.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 121

Sample mean = 23.4

Sample standard deviation = 3.65

Level of significance = 0.05

Degree of freedom

= n - 1 = 120

95% Confidence interval:  

\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Calculation of critical value:

t_{critical}\text{ at degree of freedom 120 and}~\alpha_{0.05} = \pm 1.9799  

Putting the values, we get,  

23.4\pm 1.9799(\dfrac{3.65}{\sqrt{121}} )\\\\ = 23.4 \pm 0.6569\\\\ = (22.7431 ,24.0569)\approx (22.74,24.06)  

(22.74,24.06) is the required 95% confidence interval for the population mean ACT score of University of Oklahoma students.

Margie has 5 times as many nickels as quarters. She has a total of $2.00.
stich3 [128]

Answer:

<u>Part A: </u>

<u>n = 5q (1st equation)</u>

<u>0.05n + 0.25q = 2 (2nd equation)</u>

<u>Part B:</u>

<u>q = 4 ⇒ n = 5 * 4 = 20</u>

<u>Part C:</u>

<u>Margie has 20 nickels and 4 quarters, for a total of $ 2.00</u>

Step-by-step explanation:

Let's recall that a nickel has a value of $ 0.05 and a quarter a value of $ 0.25.

Let n represent the number of nickels and q represent the number of quarters.

Part A:

Write a system of equations to represent the situation.

n = 5q (1st equation)

n * 0.05 + q * 0.25 = 2

0.05n + 0.25q = 2 (2nd equation)

Part B:

Replacing n in the 2nd equation to solve for q:

0.05n + 0.25q = 2

0.05 * 5q + 0.25q = 2

0.25q + 0.25q = 2

0.5q = 2

q = 2/0.5

<u>q = 4 ⇒ n = 5 * 4 = 20</u>

<u>Part C:</u>

<u>Margie has 20 nickels and 4 quarters, for a total of $ 2.00</u>
