Answer:
.99815
which is about
99.815%
Step-by-step explanation:
we are looking for 35<x<77
We need to find (what I think is called) the z score which is acheieved through what I'm pretty sure is called standardizing
What we do is subtract the mean and then divide by the standard deviation
so for 35 we have
(35-56)/7= -3.29
due to the fact that the normal distribution is symmetric this is equal to 1-p(3.29)
to find p(3.29) grab a ztable and get p(3.29)= .9995
1-.9995= .0005
For 77 we have
(77-56)/7=3
grab a ztable and find the 3= .99865
Finally subtract these two to get the final answer
.99865-.0005= .99815
Answer:
11 + (5 + 2)² = 11 + 7²
= 11 + 49
= 60
Step-by-step explanation:
Star with the brackets.
5+2=7
7² = 49
11 + 49 = 60
Answer:
Just combine the x

Answer:
20,000,000
Step-by-step explanation:
An easy way of looking at this is just adding the non-zero digits, which in this case would be 1 and 1. After we do that, we just add the remaining amount of zeros that we did not sum:
1 + 1 = 2
Now we add 7 zeros:
20,000,000

i know this because 10 divided by 2 is 5
added to 10 because 20 divided by 2 is 10.
5+10=15
