Answer:
0.3745
Step-by-step explanation:
Data
mean (
): 80
standard deviation (
): 4
Normal distribution table is in figure attached
.
Z = (85 - 80)/4 = 1.25
Area below curve = 0.3944
Z = (82 - 80)/4 = 0.5
Area below curve = 0.0199
Proportion of exam scores between 82 and 85?
0.3944 - 0.0199 = 0.3745
What grade is this? can you maybe break it down
First do any exponents: 3 to the 0 power would equal 1. Then multiply and divide in order: 2x1=2, 2/2=1. Then subtract: 23.6-1=22.6 :)
Answer:
Step-by-step explanation:
I can't read it very well. If it says
5(6n-4)+2=68
30n-20+2=68
30n=86
n= 43/15 or 2 13/15
If it says
5(6n-4)-2=68
30n-20-2=68
30n=90
n= 3
Answer:
![p(x)=\sqrt[3]{2-x}](https://tex.z-dn.net/?f=p%28x%29%3D%5Csqrt%5B3%5D%7B2-x%7D)
Step-by-step explanation:
we know that
The parent function of the graph is equal to
![f(x)=\sqrt[3]{-x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B3%5D%7B-x%7D)
The rule of the translation is equal to
The translation is 2 units to the right
so
applying the transformation
f(x)------> p(x)
The function of the graph is equal to
![p(x)=\sqrt[3]{-(x-2)}](https://tex.z-dn.net/?f=p%28x%29%3D%5Csqrt%5B3%5D%7B-%28x-2%29%7D)
