Letter B is the correct answer
Answer:
the value of X is 122
Step-by-step explanation:
First, all triangle angles add up to 180 so to find the missing angle we subtract 51 and 71 from 180 and get 58
Now we know straight lines always equal 180 as well so we subtract 58 from 180 and get 122 and that is the value of x
Answer:
0.044
Step-by-step explanation:
n=9,p=0.9, x =6.
Apply Binomial probability we get
Sum P(x)=C(n,x)
for x=6
Putting in the formula ,
we get
P(x) = C(9,6) 
84 X 0.531441 X 0.001
= 0.044
Step-by-step explanation:
=


if the denominator is a root then multiply itself by itself to get an integer
