Answer:
3/5
Step-by-step explanation:
I did this on the test and I got this specific answer correct :)
The required mean of the data set is 3/5, or approximately 0.6 inches.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
Here,
To find the mean of the data set, we need to add up all the values and divide by the total number of values.
1/4 + 1 1/3 + 2/3 + 1/4 + 1/2 = 1/4 + 4/3 + 2/3 + 1/4 + 1/2 (we convert all fractions to have a common denominator)
= 2/3 + 4/3 + 1
We need to convert these mixed numbers to improper fractions:
= 3
Now we divide by the total number of values:
= 3 ÷ 5
= 3/5
Therefore, the mean of the data set is 3/5, or approximately 0.6 inches.

Is the average amount spent on textbooks per semester by accounting majors significantly
different from the average amount spent on text books per semester by management majors?
Answer this question with a 90% confidence interval using the following data from random
samples of students majoring in accounting or management. Discuss the assumptions
A confidence interval is simply the range of estimates for an unknown parameter, which is defined as an interval with a lower bound and an upper bound.
What is a confidence interval?
Your information is incomplete as the data is not given. Therefore, an overview of the confidence interval will be given.
A 90% confidence interval means that the researcher is 90% confident that the values of the results will simply fall between the upper and lower limits if the procedure is repeated again.
You can find a confidence level for data by simply taking half of the size of the confidence interval, then multiplying it by the square root of the sample size, and then dividing by the sample standard deviation.
Finally, look up the resulting Z or t score in a table in order to find the level.

10 CDs
Step-by-step explanation:
First, let's round the cost of each CD to the nearest whole number.
6.98 ≈ 7.00The closest multiple of 7 to 75 is 77.
Then, it would make sense that Sean can buy 11 CDs. However, he has a little bit under 77 dollars, so he can only buy 10 CDs.(If we were to do the actual calculations, 75/6.98 is 10.744.. and so on, so we can confirm he can buy no more than 10 CDs)

The solution to f(x)=g(x) is 0. Therefore, option B is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, f(x)=g(x)
f(x)=-(x+2)(x-2) and g(x)=2|x+2|
Now, -(x+2)(x-2)=2(x+2)
-(x-2)=2
x-2=-2
x=-2+2
x=0

A carpenter wants to cut an 84 inches long board into two -pieces such that one piece is twice as long as the other piece. Set an equation and find the length of each piece.
Answer:
The shorter piece is 28 inches
The long piece is 56 inches
Step-by-step explanation:
First, we need to write an equation:
-> Let x be the shorter piece after they are cut.
84 inches = x + 2x
84 inches = 3x
28 inches = x
x = 28 inches
Now we will find the length of each piece,
-> The shorter piece is 28 inches
[] x = 28 inches
-> The long piece is 56 inches
[] 2x = 2(28) = 56 inches
Checking work:
56 + 28 = 84
-> This solution should work

ABC DEF. The area of DEF is given. Find the area of ABC.
Answer:
C. 240 in^2
Step-by-step explanation:
is it stated that two triangles are similar.
If they are similar then their area must be proportional too.
The side lengths' proportion is :
12/60 = 1/5 this can be used to find the area of the smaller triangle, ABC
Let x represent the are of triangle ABC
1/5 = x/1200 cross multiply both sides
5x = 1200 divide both sides by 5
x = 240 since the area is indicated with square value so the answer is

The rule for triangles is that their angles must add up to 180. 30+50=80 and 180-80=100 so the angle next to 4 is 100. Since they are on a straight line the angle is 180 and 180-100 is 80
