Answer:
0.683
Step-by-step explanation:
We have to find P(-1<z<1).
For this purpose, we use normal distribution area table
P(-1<z<1)=P(-1<z<0)+(0<z<1)
Using normal area table and looking the value corresponds to 1.0, we get
P(-1<z<1)=0.3413+0.3413
P(-1<z<1)=0.6826
Rounding the answer to three decimal places
P(-1<z<1)=0.683
So, 68.3% of the z-scores will be between -1 an 1.
The range of a data set is the greatest value minus the smallest value.
The greatest value here is 32, and the smallest value is 27:
Answer:
It’s 40 I’m pretty sure because of the square. That’s how I was taught.
Answer:
To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.
Answer:
I would try going with 12.2
Step-by-step explanation:
If I'm correct this is very simple.
x=15
So plug that into the equation and you get
11.00+0.08x15
which equals 12.2
So I recommend trying that out :)
