10 POINTS!!! NO LINKS!! I WILL REPORT BUT PLEASE SOMEONE HELP ME The table below shows the number of students in four schools with grade
point averages in various ranges. The grade point averages of the students in
which school represent a U-shaped distribution?
Answer:
School C.
Step-by-step explanation:
The answer is school C. A u-shaped distribution would have to have values that when plotted, make a "u". In this case, the first and last values have to be the highest, the second and fourth values have to be in the "middle" and the third value has to be at the bottom. This is the case for school C.
Answer:
B. School C
Step-by-step explanation:
Having a U-shaped distribution means that the school would have the least number in the middle value/values and the most at the ends.
School C exhibits this trend because it has the most on the outermost ranges (82 for between 1.5 and 2, and 78 for between 3.5 and 4.0), as well as the least number for the middle value (26 for 2.5-3.0
The numbers inbetween also follow the trend, as you can see if you read down the column of school C, the numbers decrease as you get to 2.5-3.0 and increase again to 4.0

Answer:
x=54, acute scalene triangle
Step-by-step explanation:
1st Question:
Triangle SRT has two congruent sides, making it an isosceles triangle.
In isosceles triangles, the two base angles are congruent.
This means that in the question, ∠SRT equals ∠STR, so let's call them both x.
The sum of the interior angles of a triangle add to 180, so
∠RST+∠SRT+∠STR=180
Substitute ∠RST for 72 and ∠SRT+∠STR for x
72+2x=180
2x=108
x=54
2nd Question:
Again, using the sum of the interior angles of a triangle, we can say
42+88+∠DFE=180
∠DFE=50
All the angles in the triangle are less than 90°, meaning they are all acute. Also, none of the sides are labeled as congruent, so it is an acute scalene triangle
Last year Tyler used 60 feet of fencing to enclose a rectangular garden with an area of 200 ft². This year Tyler plans to use 120 feet of fencing to enclose a garden similar in shape. What will be the area of the garden?
Answer:
Area of new garden = 800 ft²
Step-by-step explanation:
Given:
Old fencing = Parameter of old garden = 60 ft
Area of old garden = 200 ft
Find:
Area of new garden if Parameter of new garden is 120 ft
Computation:
Assume;
Length of old garden = l
Width of old garden = b
So,
2[l + b] = 60
l + b = 30
l = 30 - b
Area of old garden = 200 ft
l x b = 200
So,
(30 - b)b = 200
b² - 30b + 200 = 0
b² - 20b - 10b + 200
b(b-20) - 10(b-20)
(b-20)(b-10)
So,
Width of old garden = 10 ft
Length of old garden = 20 ft
New parameter is double
So,
Width of new garden = 10 x 2 = 20 feet
Length of old garden = 20 x 2 = 40 feet
Area of new garden = l x b
Area of new garden = 20 x 40
Area of new garden = 800 ft²

Four friends are told that the average (mean) of their grades for their favorite class is 84.5%.
Anthony got 86%, Jasmine got 92%, and Kaitlyn got 70%.
Jonathan's grade was not revealed.
What grade did Jonathan get?
PLEASE HELP SOON
Multiply the average by number of people:
84.5 x 4 = 338
This means the total of the 4 grades need to equal 338
To find Jonathan’s grade subtract the other 3 grades from 338:
338 - 86 - 92 -70 = 90
Jonathan’s grade was 90

To buy a PS5 bundle, Amir borrowed $850 for 2 years at a simple interest rate of 2.5%. How much did he have to pay back in all? A.$42.50 B.85.00 C.$850 D.$892.50
Answer:
d.
Step-by-step explanation:
Answer:
D. $892.50
Step-by-step explanation:
First we find out the interest:
850 * 2.5% = 21.25
Since this is 2 years we multiply the interest by 2.
21.25 * 2 = 42.50
Now we add the interest with the amount borrowed.
850 + 42.50 = $892.50
So, the answer is $892.50 in total.
Hope this helps! :)
