Answer: The mean for the probability distribution will be 69.25.
Explanation:
Since we given that





As we know the formula for expectation of x i.e. known as mean for the probability distribution,

So, we apply this formula in our case,


Hence, the mean for the probability distribution will be 69.25.
Answer:2.8 feet
Step-by-step explanation:
length(l)=?
breadth(b)= 1.9 feet
perimeter(p)=7.4 feet
we know,
p=2(l+b)
7.4=2(l+1.9)
7.4=2l+3.8
2l=7.4-3.8 (changing side and bringing 3.8 to 7.4 it gets -3.8)
l=3.6/2
l=2.8 feet
Hence,length is 2.8 feet
-5 1/3, 2 1/2, 3.75 that is all i can see in the picture
