C 17. At high school A, the mean score of 50 students on a science test is 75.
At high school B, the mean score of 40 students on the same test is 80.
What is the mean score of the 90 students?
Answer:
Mean score of 90 students = 77.2
Step-by-step explanation:
Mean score of 50 students from school A = 75
Mean score of 40 students from school B = 80
We need to find mean score of the 90 students?
First we will find sum of scores of students from school A
We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]
We have Average = 75, Number of terms = 50, We need to find Sum of terms (scores)
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\75=\frac{Sum\:of\:Terms}{50}\\Sum\:of\:Terms= 75\times 50\\Sum\:of\:Terms=3750[/tex]
So, Sum of scores for School A = 3750
Now, we will find sum of scores of students from school B
We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]
We have Average = 80, Number of terms = 40, We need to find Sum of terms (scores)
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\80=\frac{Sum\:of\:Terms}{40}\\Sum\:of\:Terms= 80\times 40\\Sum\:of\:Terms=3200[/tex]
So, Sum of scores for School B = 3200
Now, We will find mean score of the 90 students?
Mean score of 90 students will be:
[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\Average=\frac{3750+3200}{90}\\Average=\frac{6950}{90}\\Average = 77.2[/tex]
So, mean score of 90 students = 77.2
THE THREE SIDES OF A TRIANGULAR LOT
ARE MEASURED TO BE APPROXIMATELY 100.52
FT, 15.321 FT AND 143.250 FT LONG. FIND THE
APPROXIMATE PERIMETER OF THE LOT
Answer:
259.09 feet
Step-by-step explanation:
Given that,
The three sides of a triangular lot are measured to be 100.52 ft, 15.321 ft and 143.250 ft.
We need to find the perimeter of the lot.
We know that,
Perimeter = sum of all sides
P = 100.52 + 15.321 + 143.250
P = 259.09 feet
So, the required perimeter of the lot is 259.09 feet.

solve the following system of equations y=9x-9 y=9
Answer:
(x, y) = (2, 9)
Step-by-step explanation:
y = 9x - 9
y = 9
Substituting the value of y ( second equation) into the first eqaution, we get:
9 = 9x - 9
18 = 9x
x = 2.
Answer:
(x, y) = (2, 9)
Step-by-step explanation:
y = 9x - 9
y = 9
Substituting the value of y ( second equation) into the first eqaution, we get:
9 = 9x - 9
18 = 9x
x = 2.

A salesperson sold a car for $15,590 and their commission is $623.60. What percentage of the sale price is their commission?
Answer:
4%
Step-by-step explanation:
623.60 deivided by 15,590= commistion
Find the percent error in this situation:
Estimated value: 145
Actual value: 189
Answer:
30.3% im so sorry if this is wrong if it is u can report this :(
Step-by-step explanation:
Answer:
23.3%
Step-by-step explanation:
You have to first take the estimated value - the actual value
= 145-189 = -44
Then you want to take -44 divide the actual value which is 189
= -44 / 189= 0.232804233
Lastly, you want to take 0.232804233 and multiply it by 100
= 0.232804233 x 100= 23.28042328
Round that number to get
=23.3%

The area in square feet of a rectangular garden can be expressed as the product of the garden’s length and width, or A(x) = 3x2 +13x +14. If the width of the garden is (x + 2) feet, what is the length of the garden?
Answer:
3x+7
Step-by-step explanation:
Use long division or synthetic division. (3x^2+13x+14)/(x+2)
The length of the rectangular garden is 3x + 7
The given expression:
[tex]A = 3x^2 + 13x + 14[/tex]
the width of the garden = x + 2
let the length of the garden = y
To find:
the length of the gardenThe area of the rectangular garden is calculated as;
[tex]A = y(x + 2) = 3x^2 + 13x + 14\\\\y(x + 2) = 3x^2 + 13x + 14\\\\y = \frac{3x^2 + 13x + 14}{x + 2}[/tex]
Using long division method:
3x + 7
------------------------------
x + 2 √ 3x² + 13x + 14
- (3x² + 6x)
-------------------------
7x + 14
- (7x + 14)
-------------------------------
0
Thus, the length of the rectangular garden, y = 3x + 7

We defined an argument as a reasoned or thoughtful process. The correct option is A.
What is an argument?An argument is a statement or set of claims known as premises that are designed to assess the degree of truth or acceptability of another statement known as the conclusion. Arguments may be analyzed from three different perspectives: logical, dialectical, and rhetorical.
Since the act or process of arguing, reasoning, or discussing is known as an argument. Therefore, we defined an argument as a reasoned or thoughtful process.
An argument is made up of three parts: the conclusion, the premises, and the assumptions.
THE ConclusionThe conclusion (or theses) is the point of the argument's major idea—what the author is attempting to show.
THE LOCATIONThe premises are the reasoning or evidence provided by the author to justify the conclusion.
THE ASSURANCESThe assumptions support the conclusion, but unlike the premises, they are unsaid and so invisible.
They connect the premises and conclusions.
