Step-by-step explanation:
Step 1
Subtract the mean from your score. For example, if you scored 33 and the mean is 24, you would get a difference of 9.
Step 2
Divide the difference found in Step 1 by the standard deviation of the data to find the z-score, which is the number of standard deviations away from the mean that your score is. For example, if the standard deviation was 4.5, you would have a z-score of 2.
Step 3
Convert the z-score to a percentile using a z-score chart or converter available online (see Resources section). When converting, be sure to use a one-sided test. For example, a z-score of 2 would be in the 98th percentile.

453 have a nice night
Step-by-step explanation:
Answer: 32 divided by 4 = 8
Step-by-step explanation:
If the diagram is 8 ovals with 4 squares each, and we know that this is a division, then we have that an unknown number X is such that:
X/4 = 8
this is because we know that the division is by 4 (the number of squares in each oval) and the solution of the division is the number of ovals.
Then we can solve the equation for X.
X/4 = 8
We multiply each side of the equality by 4
X = 4*8 = 32
Then the diagram represents the division:
32/4 = 8 or " 32 divided by 4 = 8"
Answer:
88 cm²
Step-by-step explanation:
w = x
l = x + 3
P = 38
We know that 
, so we substitute known values:
Therefore, we know that the width (x) is 8 cm and the length (x + 3) is 8 + 3 = 11 cm. To verify, we can check that the perimeter equals 38:
8 + 11 + 8 + 11 = 38. <em>Check.</em>
Thus, the area of the rectangle is:
Therefore, the area is 88 cm².
V=hpir^2
r=10
v=6283
6283=hpi10^2
6283=100hpi
divide both sides by 100
62.83=hpi
aprox pi=3.141592
divide both sides by pi
19.9994143=h
so about 20 inches
