PLEASEEEEE HELP THIS IS FOR AP STATS
Many colleges and universities require applicants to submit scores on standardized tests such as the SAT Writing, Math, and Critical Reading (Verbal)
tests. The college your little sister wants to apply to says that while there is no minimum score required, the middle 50% of their students have
combined SAT scores between 1530 and 1850. You'd feel confident if you knew her score was in their top 25%, but unfortunately she took the ACT
test, an alternative standardized test.
How high does her ACT score need to be to make it into the top quarter of equivalent SAT scores?
To answer this question you'll have to standardize all the scores, so you'll need to know the mean and standard deviations of scores for some group
on both tests. The college doesn't report the mean or standard deviation for their applicants on either test, so we'll use the group of all test takers
nationally. For college-bound seniors, the average combined SAT score is about 1500 and the standard deviation is about 250 points. For the same
group, the ACT average is 20.8 with a standard deviation of 4.8.

Name the shaded angle in three different ways.
Answer:
The answers would be:
- ZYX
- XYZ
- Y
Step-by-step explanation:
This is because they will all make up the angle.
If you look at the other angles, such as:
XZY and YZX
It is crossing over from X to Z this is not possible as it not only doens't make any sense, but would not be creating the same angle as what is presented.
This also goes for, YZX instead of going in the correct angle, it would cross over from Z to X.
I need the answer for this question it is too difficult for me
Answer:
b
Step-by-step explanation:
Use the formulas.
The formula for sphere is volume = 4πr³/3
We are using 3.14 for pi,
So its volume is about 7234.56.
The formula for cone is volume = πr²h / 3
r is the radius and h is the height.
So the volume of the cone is about 3617.28
Now, subtract.
You get 3617.28.
Choice D is the answer.
Pls help me soon! :)
Answer:
x=32
y=35
Step-by-step explanation:
x= 32 degrees by vertical angles
y= 35
180-90-23-32= 35
< HG =180
<GOE = 23
<EOA = x = 32
<HOC = RIGHT ANGLE = 90

On 31st August 2018, Musk Traders purchased a machine on credit for a cost price of R402 500 (including VAt at 15 percent). Machinery is depreciated over six years according to the straight line basis and there is no residual value on this machine as it is highly specialised. Musk Traders has a 30 June year-end.
Calculate the depreciation and accumulated depreciation for 2019 and 2020
Answer:
The depreciated asset price has to be independent of VAT;
= 402,500/1.15
= $350,000
Annual Depreciation = 350,000/6 years
= $58,333
Musk Trading has a 30 June year end so;
2019September to June = 10 months
Depreciation;
= 58,333 * 11/12
= $48,611
Accumulated Depreciation = $48,611
2020Depreciation = Annual depreciation of $58,333
Accumulated depreciation
= 2019 depreciation + 2020 depreciation
= 48,611 + 58,333
= $106,944

6. A landscaping company ordered 13 plants and 4 trees for a total of $487. If plants are $8 each write and solve a linear equation to find the cost for each tree
Answer:95.75
Step-by-step explanation:
13x + 4y = 487
13*8 + 4y = 487
4y = 487 - 13*8
y = (487 - 13*8)/4
y = dollars per tree = 95.75
Answer:
trees are $95.75
Step-by-step explanation:
13(8) + 4t =487
104 + 4t= 487
104 -104 + 4t = 487 -104
4t = 383
4/4t = 383/4
t = 95.75
question 2 I mark as brainliest
Answer:
D: 3x(4+6)
Step-by-step explanation:
it tells you that you need to add 4 and 6 and then multipy the SUM of that by 3. so you would need to have the 4+6 in parenthesis and then multiply the 3 later
Segment HK is divided by point J at a ratio of 3.4. If H(6,9) and J(12, 18), what are the coordinates of point K?
Answer:
Step-by-step explanation:
[tex]x=\frac{mx2+nx1}{m+n}\\let~coordinates ~of~K~be~(x,y)\\12=\frac{3x+4*6}{3+4}\\12*7=3x+24\\3x=84-24\\3x=60\\x=60/3=20\\18=\frac{3y+4*9}{3+4}\\18*7=3y+36\\3y=126-36\\3y=90\\y=90/3=30\\so~K~is~(20,30)[/tex]
If f(x) = 6x +5 and g(x) = 2x – 7 find (fºg)(x)
Answer:
f(g(x)) = 12x - 37
Step-by-step explanation:
Step 1: Define
f(x) = 6x + 5
g(x) = 2x - 7
Step 2: Find f(g(x))
f(g(x)) = 6(2x - 7) + 5
f(g(x)) = 12x - 42 + 5
f(g(x)) = 12x - 37

Which numbers are a distance of 6 units from 2 on the number line
Answer:
{-4, 8}
Step-by-step explanation:
If 2 is the right-most number, the other one is ...
2 -6 = -4
If 2 is the left-most number, the other one is ...
2 +6 = 8
The numbers -4 and 8 are 6 units from 2 on the number line.
What value(s) of x make the following equation true?
2x - 6 = 3x + 1 - 2x - 7
Answer:
x = 0
Step-by-step explanation:
2x−6=3x+1−2x−7
Step 1: Simplify both sides of the equation.
2x−6=3x+1−2x−7
2x+−6=3x+1+−2x+−7
2x−6=(3x+−2x)+(1+−7)(Here we Combine Like Terms)
2x−6=x+−6
2x−6=x−6
Step 2: Subtract x from both sides.
2x−6−x=x−6−x
x−6=−6
Step 3: Add 6 to both sides.
x−6+6=−6+6
x=0
What is the value of X?
Answer:
11.5
Step-by-step explanation:
4x+14=60

The volume of a cube is 27 in^3 How long is each side ? Show and explain your work for full credit.
Answer:
a = 3 inch
Step-by-step explanation:
Given that,
The volume of a cube is 27 cubic inches.
We need to find the side of the cube.
We know that, the formula for the volume of the cube is given by :
[tex]V=a^3[/tex]
a is the side of the cube
[tex]a=(V)^{1/3}[/tex]
Put V = 27
so,
[tex]a=(27)^{1/3}\\\\a=(3\times 3\times 3)^{1/3}\\\\a=3\ \text{inch}[/tex]
So, the side of each side of a cube is 3 inches.

2n - 7 = 5?? help pleases
Answer:
n=6
Step-by-step explanation:
2n-7=5 (add 7 to -7 and 5)
2n=12 (divide both sides by two)
Solution:
n=6
Answer:
N = 1
Step-by-step explanation:
1.- 2n - 7 = 5
Subtract 5 on both side of the equal sign
2.- 2 = 2n
Divide 2 on both side to get the "n" by itself
