Which brand should the store eliminate?
Answer:
Brand D has the highest return rate so they should eliminate that one.
Step-by-step explanation:
brand A - .0481
brand B - .0307
Brand C - .0410
Brand D - .0788
The store should eliminate Brand D.
What is return rate?Return rate refers to the percentage of products or items that are returned to a seller or retailer by customers.
It is calculated by dividing the number of items returned by the total number of items sold and multiplying by 100 to get a percentage.
We have,
To determine which brand to eliminate, we need to calculate the return rate for each brand.
The return rate is the ratio of the number of items returned to the total number of items sold.
The brand with the highest return rate is the most likely to be returned and should be eliminated.
Using the data given in the table, we can calculate the return rate for each brand as follows:
Brand A: 22/457 = 0.048
Brand B: 10/328 = 0.031
Brand C: 21/511 = 0.041
Brand D: 19/241 = 0.079
Therefore,
Brand D has the highest return rate at 0.079 or 7.9%, which means it is the most likely to be returned.
The store should eliminate Brand D.

SOMEONE HELP ME WITH MATH PLEASE !
Answer:
C
Step-by-step explanation:
First, eliminate choice B b/c the max is 28, not 26.
Next, lets find the median.
(12+18+20+20+24+26+28+28) = (20+24)/2 = 22
That leaves us with only A & C as a possible answer.
Q1 = The median of the first half of the data (12, 18, 20, 20)
Q1 = (18+20) / 2 = 19
A & C have the same Q1 values, so we need to compare Q3 values.
Q3 = The median of the second half of the data (24, 26, 28, 28)
Q3 = (26+28) / 2 = 27
The Correct Answer is C b/c A had a different Q3 value.

Answer:
[tex]x=27[/tex]
Step-by-step explanation:
The two angles are set within a right angle, so the sum of the two angles must equal 90 degrees. These two angles are known as complementary angles. Simply subtract 90 from 63 to get the missing angle measure of 27 degrees.
If this helped, a brainliest answer would be greatly appreciated!
if that is a 90 degree angles and it tells you that the bigger angle on the bottom is 63 degrees than the top angle would be 27 degrees.

Use the drawing tools to form the correct answers on the graph.
Plot the zeros of this function:
f(x) = (x – 1)(x – 7).
Answer:
Zeros of the given function are x = 1, 7
Step-by-step explanation:
Given function is,
f(x) = (x - 1)(x - 7)
For zeros of the function,
f(x) = 0
(x - 1)(x - 7) = 0
(x - 1) = 0
x = 1
(x - 7) = 0
x = 7
Therefore, zeros of the given function are x = 1, 7
We can find the zeros by suing a graphing tool.

the shape the object forms in a container
the amount of space the object takes up
9514 1404 393
Answer:
the object’s mass
Step-by-step explanation:
The mass of the object will be the product of volume and density.
The object's mass can be calculated.

Knowing the volume, you know the amount of space the object takes up—no calculation is necessary. However, that is not enough information to calculate the size or shape.
Answer: the objects mass
