Explain how to use the standard normal table to find the probability associated with the shaded
area under the curve.
A
^
-3
-2.
0
1
2
3
0.4
1.9

Step-by-step explanation:

First, go to a z-table and find the value associated with .4 (.6554). Then go find the value assocaited with 1.9 (.9713) and you just subtract them (.9713-.6554)= .3159 which is equal to 31.59%

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
