A sample of students is taken from the school’s A honor roll. The school estimates that there are actually 360 students on the A honor roll. Using this sample, how many students on the A honor roll are 8th graders?
6thgraders=15
7thgraders=11
8thgraders=14
Answer:
Number of 8th Graders = 360 - X
As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from 8th grade.
As we know:
Total number of students on the A honor roll = 360
We are asked to calculate, number of students from 8th grade on the A honor roll.
So, let's assume that "X" represents all the students who are on the A honor roll except 8th grade.
Mathematical Expression:
Number of 8th Graders = Total number of students on the A honor roll - X
Number of 8th Graders = 360 - X
So, if you know the value of X, you can easily calculate the number of students which are from 8th grade on the A honor roll.

Find the area of each. Use pi = 3.14
I'll give points and brainalist for answer / explanation
Answer:
557.8
Step-by-step explanation:
Because the semi circle on the top and the semi circle on the bottom form a circle with an area of 314.16.
The semicirlces on either side form a circle with an area of 66.48.
Then the rectangle in the middle has an area of 9 times 20 which is 180.
If you add those areas together you get the total area which is about 557.8

The slope is
Find the slope.
m =
help please
Step-by-step explanation:
In order to find the slope, we must know the formula needed.
[tex]\frac{y2}{x2} -\frac{y1}{x1} =m[/tex]
Using 2 given points, we can subtract both and receive our final answer.
Points that are provided:
(4, 3)(1, -1)Substitute the given points into the formula format.
Then, solve.
[tex]\frac{3}{4} -\frac{-1}{1} =\frac{4}{3}[/tex]
m = 4/3
The slope is positive. Meaning that the slope is increasing for the value of y.

[tex] \sf \: 2x + 4 + 62 = 90[/tex]
simplify addition:
[tex] \implies \sf 2x + 66 = 90[/tex]
subtract 66 from both sides:
[tex] \sf\implies 2x + 66 - 66 = 90 - 66 \\ \sf\implies2x = 24[/tex]
divide both sides by 2:
[tex] \sf \implies \: \frac{2x}{2} = \frac{24}{2} \\ \sf \therefore \: x = 12[/tex]
Answer:
Solution given:
62°+2x+4+90=180°[ sum of interior angle of a triangle is 180°]
2x=180-156°
x=24°/2
x=12°

Answer/Step-by-step explanation:
✔️Diagonals of a rhombus bisect each other at 90°.
Therefore,
m<1 = 90°
✔️Since opposite sides of a parallelogram are parallel, therefore:
m<2 = 53° (alternate angles)
✔️Diagonals bisect each angle of a parallelogram, therefore,
m<3 = m<2
m<3 = 53°
✔️m<4 + m<3 + 90° = 180°(sum of triangle)
m<4 + 53° + 90° = 180° (substitute)
m<4 = 180 - 143
m<4 = 37°

Answer:

Step-by-step explanation:
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $8 monthly fee and charges an additional $0.12 for each minute of calls. The second plan has a $18 monthly fee and charges an additional $0.7 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
200 minutes
Step-by-step explanation:
Let us assume the number of minutes be x
Now the two equations are
$8 + 0.12x = 0
And, $18 + 0.7x = 0
In the case when the cost of the two plans is equal
So
$8 + 0.12x = $18 + 0.7x
$8 - $18 = 0.7x - 0.12x
-$10 = -0.05x
x = 200 minutes

How can you use standard deviations to compare the spread of each data set?
Sample A: 2,5,1,2,3,3,4,3
Sample b: 10,5,1,2,3,7,4,3
Calculate the standard deviation for each data set:
Sample A = 1.246
Sample B = 2.924
The smaller the deviation the closer the data set is, the larger the deviation the more widespread the data set is.
Sample B has a larger deviation so the spread of the data is wider.
Daniel puts some wheat flour into an empty bowl. Then he add 2/3 cup rye flour to make a total of 2 5/12 cups of flour. How much wheat flour is in the bowl.
Answer:
1 3/4 cups of wheat flour is in the bowl
Step-by-step explanation:
x + 2/3 = 2 5/12
First, convert the 2/3 to 12ths by multiplying numerator and denominator by 4 = 8/12
Then convert the 2 5/12 to an improper fraction 29/12
x + 8/12 = 29/12
subtract 8/12 from both sides
x = 21/12 = 1 9/12 = 1 3/4

18 girls and 12 boys on a swim team. what is the percentage of boys?
Answer:
40%
Step-by-step explanation:
The first step is to add 18 girls + 12 boys, which gives you the total number of people on the swim team, 30.
Next, you divide the 12 boys by the total swim team members, so:
[tex]\frac{12}{30}[/tex] = 0.4
Then, you multiply 0.4 by 100 to get the percentage:
0.4 × 100 = 40
Therefore, the swim team is made up of 40% boys, and 60% girls.
Answer:
40%
Step-by-step explanation:
30 total kids
12/30 as a decimal is 0.4
to make a decimal into a percent you move the decimal point 2 times to the right
that would be 40
then add the percent to make 40%
