You sell 200 laptops per month at $499 per laptop. You sell 350 smartphones per month at $399 per phone. Which
generates more sales in dollars for you?
a) Laptops
b) Smartphones
Answers
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 laptopTo find the total revenue of all these laptops we need to multiply 200 by 499.
[tex](200) *(499) = 99,800[/tex]
Therefore, the total revenue of the laptops alone is $99,800.
Now, let's do the smartphones.
Given:
350 smartphones/month$399 per smartphoneTo find the total revenue of all these smartphones we need to multiply 350 by 399.
[tex](350) * (399) = 139,650[/tex]
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!

Replacing the maximum value of the data set with a smaller number will also affect the mean. A:always B:sometimes C:never
Answers
Answer:
B: sometimes
Step-by-step explanation:
Let's look at two examples.
Example A.
2, 3, 5: mean is 3
Replace 5 with 1. Now you have 1, 2, 3: mean is 2.
In this case, it affected the mean.
Example B.
2, 3, 5: mean is 3
Replace 5 with 4. Now you have 2, 3, 4: mean is 3.
In this case, it did not affect the mean.
As you can see, replacing the maximum value of the data set with a smaller number may or may not change the mean.

Carlos can run 5 miles in 45 minutes, Kelly can run 10 miles in 80 minutes, and Mick can run 30 miles in 170 minutes
Answers
Answer:
Mick can run farther in less time if that's the question
Step-by-step explanation:
Mick's speed is faster.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
Carlos can run 5 miles in 45 minutes.
45 minutes = 45/60 = 0.75 hours
Speed.
= 5/0.75
= 6.66 miles per hour.
Kelly can run 10 miles in 80 minutes.
80 minutes = 1.33 hours
Speed.
= 10/1.33
= 7.5 miles per hour.
Mick can run 30 miles in 170 minutes
170 minutes = 2.8 hours
Speed.
= 30/2.8
= 10.7 miles per hour
Thus,
Mick's speed is faster.

Answer:
The right answer is A
Step-by-step explanation:
The value of the exponential equation is y = 3ˣ and the graph is plotted
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
y = 3ˣ be equation (1)
Now , the y intercept of the equation is when x = 0
So , when x = 0
y = 3⁰
y = 1
Now , when y₁ = 3^1.2
The value of y₁ = 3.7
Therefore , the y intercept of the equation is 1 and the graph is plotted
Hence , the exponential equation is y = 3ˣ
