Answer:
2 2/3 projects
Step-by-step explanation:
First disect the statement.
2/3 of a project in 1/4 of an hour.
This means that she does not completely finish grading a project in a quarter hour.
We want to know how much she gets done in one whole hour, however all we know is how much she gets done in 1/4 of that time. Luckily, 1/4 times 4 is a whole hour. Since 2/3 of a project gets done in 1/4 that means if we multiply 2/3 by four we should also get how much she completes in one hour.
2/3 x 4 = 8/3
8/3 = 2 2/3 projects
You can also right these as ratios:
(2/3)/(1/4) = x/1
x = 8/3
How much change did she receive?

Determine the intercepts of the line.
9514 1404 393
Answer:
y-intercept (0, -6)
x-intercept (-8, 0)
Step-by-step explanation:
You're writing the coordinates of the points where the line crosses the axes.
The y-intercept is where the line crosses the y-axis. The y-coordinate there is -6. Because it is the y-axis, the x-coordinate is 0. Written as an ordered pair, the y-intercept is (0, -6).
The x-intercept is where the line crosses the x-axis. The x-coordinate there is -8. Because it is the x-axis, the y-coordinate is 0. Written as an ordered pair, the x-intercept is (-8, 0).

The volume of this cylinder is approximately 416,992 cubic inches.
The height is ___ inches.
Use ≈ 3.14.
Answer:
83
Step-by-step explanation:
height = [tex]\frac{volume}{\pi *r^{2} }[/tex]
height = [tex]\frac{416992}{3.14*(40)^{2} }[/tex]
height = 83
Answer:
Step-by-step explanation:
V = pi * r^2 * h
V = 416992
r = 40 inches.
pi = 3.14
416992 = 3.14 * 40^2 * h
416992 = 3.14 * 1600 * h
416992 = 5024 * h
416992 / 5024 = h
h = 83
Three boys were playing balls. Ben's ball bounced eight more times than Menard's . Menard's ball bounced half as many times as Diego's. Diego's ball bounced eight times. How many times did Ben's ball bounced?
Answer:
12 bounce
Step-by-step explanation:
Let :
Number of Menard's bounce = x
Ben's bounce = x + 8
Diego's bounce = 2x
If Diego's bounce = 8
Then ;
2x = 8
x = 8/2
x = 4
Ben's bounce = x + 8
Ben's bounce = 4 + 8 = 12

What is the solution to the equation 6x+2=9x-1?
O X=-3
O x=-1
Ox=1
O X=3
Answer:
x=1
Step-by-step explanation:
6x+2=9x-1
You first want to isolate the variable to one side, so subtract 6x and 9x
2=9x-1
-6x
2=3x-1
Now you want to get rid of the constant, so add 1 to the other side
2=3x
+1
3=3x
Now divide both sides by 3 to remove the 3 from x.
3/3=3x/3
1=x

Answer:
f(8) = 195
Step-by-step explanation:
When the x if f(x) is replaced with an 8, this just means that it is the eighth term. All you really have to do is replace every X in the function to find the answer.
f(8) = 3 + 3(8)²
f(8) = 3 + 3(64)
f(8) = 3 + 192
f(8) = 195

A high school basketball coach is selecting his team. The minimum and maximum height requirements are as follows:
Point Guard: Small Forward: Center:
6’2" – 6’6" tall at least 6’6" tall at least 6’8" tall
The heights of the Lincoln High School boys have a normal distribution with a mean height of 70 inches and the standard deviation of 4 inches.
Which statement is true?
A. About 16% of the boys are eligible to be a point guard on the team. B. About 2% of the boys are eligible to be a small forward on the team. C. About 48% of the boys are eligible to be a small forward on the team. D. About 34% of the boys are eligible to be a point guard on the team.
Answer:
B. About 2% of the boys are eligible to be a small forward on the team
Step-by-step explanation:
Recall : 1 feets = 12 inches
Point guard = 6’2" – 6’6" tall = 74 - 78 inches
Mean = 70 ; Standard deviation = 4
Z = (x - mean) / standard
P(x < 74) = (74 - 70) / 4 = 1
P(x < 78) = (78 - 70) / 4 = 2
0.97725 - 0.84134 = 0.13591
Small forward : 6'6" = 78 inches
P(x ≥ 78) = (78 - 70) / 4 = 2
P(z ≥ 2) = 0.02275 = 2.275% about 2%
Centre : 6'8" = 80
P(x ≥ 80) = (80 - 70) / 4 = 2.5
P(z ≥ 2.5) = 0.0062097 = 0.62%
About 2% of the boys are eligible to be a small forward on the team. Then the correct option is B.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
A high school basketball coach is selecting his team.

The heights of the Lincoln High School boys have a normal distribution with a mean height of 70 inches and a standard deviation of 4 inches.
The value of the z-score will be
[tex]z = \dfrac{x - \mu }{\sigma}[/tex]
[tex]P(x < 74) = \dfrac{74-70}{4} = 1 \\\\P(x < 78) = \dfrac{78-70}{4} = 2[/tex]
0.97725 - 0.84134 = 0.13591
Small forward: 6'6" = 78 inches
