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
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!

Consider that a population of fruit flies grew in a 40-day experiment. Average rate of change: 9 flies/day. Find the average growth rate from day 30 to day05
Answer: Average Growth Rate is 24.19%
Step-by-step explanation:
Given that;
Average rate of change = 9 flies/day
Average growth rate of change = ?
we can determine the average growth rate of change from the expression;
Average Annual Growth Rate = [((Present Value - Past Value)^1/N) - 1 ] × 100%]
Now our present value; 30th day = 9 × 30 = 270
past value; 05th day = 9 × 05 = 45
the value of N = 30 - 5 = 25
so we substitute
Average Annual Growth Rate = [((270 - 45)^1/25) - 1 ] × 100%]
= ([1.2419 - 1) × 100]
= 24.19%
Therefore Average Growth Rate is 24.19%

which integer is the smallest?
A: 0
B: 29
C: -30
D: -1
Answer:
-30
Step-by-step explanation:
0 is greater the -30 and -1 but less then 29
29 is greater then 0, -30, and -1
-1 is less the 0 and 29 but greater then -30
-30 is less then 0, 29, and -1

given the grph of the function F(x) below, what happens to F(x) when x is a negative number with a large absolute value?
Answer:
F(x) is a large positive value
Step-by-step explanation:
If it is a negative number with a large absolute value say |-250| it would become positive 250 so f(x) would also be a large positive number

Divide each side by 12 (the GCF).
Answer:
9: 16 for 9 to 16; is the simplest form for 9/16 cuz nothing can go into 9 and 16
5 : 6 for 10 to 12; cuz 10 divided by 2 is 5 and 12 divided by 2 is 6!
5: 4 for 20 to 16; cuz 20 divded by 4 is 5 and 16 divded by 4 is 4
lastly is 2:3 for 24 to 36; why? well it's ciz 24 divided by 12 is 2 and 36 divedde by 12 is 3

Step-by-step explanation:
Replacing the maximum value of the data set with a smaller number will also affect the mean. A:always B:sometimes C:never
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.

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

two students have examined the scatter plot shown in have created in line best fit for the data. student A believes that the line of best fit for the data is y= -2x + 24, while student B believes that the line of best fit for the data is y = 1.5 + 23
*Determine which student created a better line of best fit given the data in the graph.
Answer:
Step-by-step explanation:
im pretty sure its student a not 100% sure tho
The line of best fit is simply the trending line of a graph
Student A creates a better line of best fit
The linear equations are given as:
[tex]\mathbf{y = -2x + 24}[/tex]
[tex]\mathbf{y =1.5x + 23}[/tex]
The given graph shows a negative linear association.
This is so because, as the x-values increases, the y-values decreases.
This in other words means that:
The slope of the graph is negative
A linear graph is represented as:
[tex]\mathbf{y = mx + c}[/tex]
Where: m represents slope
By comparison
m = -2 and m = 1.5 for the equations of the two students.
Because the slope of the graph is negative, then
m =-2 is correct
Hence, student A creates a better line of best fit

There exists a similarity transformation that maps AABC to AA'B'C'. The measure
of ZAis 68°, and the measure of ZBis 46°. What is the measure of ZC'in
degrees?
Answer:
∠C' = 66°
Step-by-step explanation:
Because triangles ABC and A'B'C' are similar, their angles are still the same; only their side lengths are different, though still proportionate.
Hence, ∠A = ∠A', ∠B = ∠B', and ∠C = ∠C'.
Here, we're given that ∠A = 68, which means ∠A' = 68; we also know that ∠B = 46, so ∠B' = 46.
We want to find C', so remember that all angles in a triangle sum to 180:
∠A' + ∠B' + ∠C' = 180
68 + 46 + ∠C' = 180
114 + ∠C' = 180
∠C' = 66°
Answer:
∠C' = 66°
Step-by-step explanation:
∠A' + ∠B' + ∠C' = 180
68 + 46 + ∠C' = 180
114 + ∠C' = 180
∠C' = 66°
