Hey there!
We simply have to do 182/2.8, and you will get the area (65m^2).
We know that the formula for area is length x width, and the formula for volume is length x width x height. In the volume formula, we can see it can also be area x height to get volume. So, we know that area x height = volume, right? And in this equation, we are given volume and height. If V = ha, with V = volume; h = height; a = area, we can divide "h" on both sides, and we get V/h = a, or volume divided by height is area. To solve for the above equation, we can plug the numbers in the formula: 182/2.8 = a, or 65 = a.
Hope this helps! Have an amazing day, and remember, you've got this!
a college says it admits only people with sat scores among the top 10%. how high an sat score does it take to be g
Full question:
Suppose SAT scores among students are normally distributed with a mean of 500 and a standard deviation of 100.
If a college says it admits only people with sat scores among the top 10%. how high a sat score does it take to be eligible?
Answer and explanation:
To find where SAT score of student falls in the test given mean and standard deviation of scores, we can calculate: x-500/100 where x is number of SAT score of students
A sat score in the top 10% region would have a score better than 90% of other SAT scores. Therefore 0.90 has a z score of 1.28
We use algebra to find the score to be eligible thus:
1.28=x-500/100
x-500=128
x=128+500
x=628
Therefore to be eligible, a student needs to score at least 628, and be in the top 10% of scores

Roulette is a casino game that involves players betting on where a ball will land on a spinning wheel. An
American roulette wheel has 38 numbered slots - half of the slots from 1 to 36 are red and the other half are
black. Slots 0 and 00 are both green.
Suppose that a player bets $1 on the color red. If the ball lands in a red slot, the player gets their initial $1 back
plus a payout of $1. If the ball doesn't land in a red slot, they lose their $1 bet. Let X = the player's net gain
from a $1 bet on a the color red. Here is the probability distribution of X:

IS 7 7 Solve for a = √[? [] a a = 4 Enter the number that goes beneath the radical symbol 4 Enter
Answer:
[tex]a=\sqrt{33}[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know b and c we can plug that in to find out what a could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\a^2+4^2=7^2\\a^2+16=49\\a^2=33\\\sqrt{a^2}=\sqrt{33}\\a=\sqrt{33}[/tex]
So a would equal whatever the square root of 33 is.
A library has five copies of a certain textbook on reserve of which two copies (1 and 2) are hardcover books and the other three (3, 4, and 5) are softcover books. A student examines these books in random order, stopping only when a softcover book has been selected. One possible outcome is 5, and another is 213. (Enter your answers as a comma-separated list. Enter Ø for the empty set.)
Required:
a. List the outcomes in S
b. Let A denote the event that exactly one book must be examined. What outcomes are in A?
c. Let B be the event that book 5 is the one selected. What outcomes are in B?
d. Let C be the event that book 1 is not examined. What outcomes are in C?
Answer and Step-by-step explanation:
(a) Since the student have to stop when he gets to w softcover book, then the sample space should always stop at either 3 or 4 or 5. If the students examines the books randomly and stops at a softcover book, here are the possible ways he could carry this out,
S = {3, 4, 5, 13, 14, 15, 23, 24, 25, 123, 124, 125, 213, 214, 215}
2. Since only one book is to be examined then the student must check only one softcover book and end the examining. To do this, either he examines just 3 or 4 or 5. Therefore,
A = {3, 4, 5}
3. We need to pick the possibilities from the sample space that shows that the examining ended at book 5. Therefore,
B = {5, 15, 25, 125, 215}
4. We need to pick possibilities from the sample space that shows that book 1 was not examined. Therefore,
C = {3, 4, 5, 23, 24, 25}
Which of the following is a linear function?
0 x= 1/3x=y - 3
Oy = x^3 + 2
Oy = 6x^2
Oy = 2/3х
The linear functions are 1/3x=y-3 and y=2/3x. Therefore, options A and D are the correct answer.
What is a linear function?A linear function is a function that represents a straight line on the coordinate plane. The highest power of the variable is one.
Given are some equation, from the options, we need to identify which is a linear function.
1/3x=y-3 is the linear function in two variables.
y=x³ is the cubic function.
y=6x² is the quadratic function.
y=2/3x is the linear function in one variable.
Therefore, the linear functions are 1/3x=y-3 and y=2/3x.

C. 41.0, θ = 77.3°
D. 97.6, θ = 24.2°
9514 1404 393
Answer:
C. 41.0, θ = 77.3°
Step-by-step explanation:
The sum is ...
5(8, 4) -3(-3, -4) +8(-5, 1) = (5·8-3(-3)+8(-5), 5·4-3(-4)+8·1)
= (40+9-40, 20+12+8) = (9, 40)
The magnitude is ...
√(9² +40²) = √1681 = 41
The angle is ...
arctan(40/9) ≈ 77.3°
The resultant magnitude and direction is 41∠77.3°.

How far does he travel in 6 hours?
How many hours does it take to 52 miles?
Answer:
It took Markus half an hour to drive home from work. He averaged 34 miles per hour. How far does Markus live from his work?
Solution
We are given that it takes 1/2 an hour for the trip. This is a time:
t = 1/2
We are given that he averages 34 miles per hour. This is a rate:
r = 34
We are asked how few he has traveled. This is a distance. We use the d=rt equation:
d = rt
= (34)(1/2)
= 17
Markus lives 17 miles from work.

Complete the table of values for y=3-2x
Answer:
1) y = -1
2) y = 3
3) y = 5
4) y = 9
Step-by-step explanation:
1) when x = -2
y = 2x + 3
y = 2(-2) +3
y = -1
2) when x = 0
y = 2x + 3
y = 2(0) +3
y = 3
3) when x = 1
y = 2x + 3
y = 2(1) +3
y = 5
4) when x = 3
y = 2x + 3
y = 2(3) +3
y = 9
A sample of 173 students using Method 1 produces a testing average of 88. A sample of 127 students using Method 2 produces a testing average of 53.5. Assume the standard deviation is known to be 12.22 for Method 1 and 13.59 for Method 2. Determine the 95% confidence interval for the true difference between testing averages for students Method 2.
Answer:
43 < μ₁ - μ₂ < 49
Step-by-step explanation:
Sample 1:
Mean x₁ = 88
Sample size n₁ = 173
Sample standard deviation s₁ = 12,22
Sample 2:
Mean x₂ = 53,5
Sample size n₂ = 127
Sample standard deviation s₂ = 13,59
CI 95 % α = 5% α = 0,05 α/2 = 0,025
We need to find:
( x₁ - x₂ ) - tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂) < μ₁ - μ₂ < ( x₁ - x₂ ) + tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂)
v = degree of fredom
v = [ ( s₁²/n₁ + s₂²/n₂)² / (s₁²/n₁)² /n₁-1 + (s₂²/n₂)²/n₂-1
v = [ (0,86 + 1,45 ) / 0,0043 + 0,017
v = 2,31 / 0,0213
v = 108
Then t 0,025, 108 from t table is: We will take v = 100
t = 1,984
Now
√ (s₁²/n₁ ) + (s₂²/n₂) = √ 0,86 + 1,43
√ 2,3 = 1,51
Then: CI:
(173 - 127 ) - 1,984*1,51 < μ₁ - μ₂ < ( 173 - 127 ) + 1,984*1,51
46 - 3 < μ₁ - μ₂ < 46 + 3
43 < μ₁ - μ₂ < 49
