Answer: d. np(1 - p).
Step-by-step explanation:
Let x be any binomial variable which represents the number of success such that , where n is the sample size or the total number of trials and p is the probability of getting success in each trial .
Then, the mean E(x) and the variance Var(x) for the binomial distribution is given by equation :
where n is the sample size or the total number of trials and p is the probability of getting success in each trial .
Therefore , the correct option is option d. np(1 - p) .
Step-by-step explanation:
do 21×3.14= 65.94
then divide by 2 since its a semicircle
equals: 32.97
than find perimeter altogether
21+28+28+32.97= 109.97ft
So if they are similar then just try to figure out which two sides correspond to each other from the first and then the second triangle.
See how in the above example I did 20 and 5 not 20 and 14 or 20 and 3.5 because they do not correspond with one another.
Then figure out, is x on the mama or baby shape and either multiply the number received from all proportions or divide.
Multiply : small to big ( # missing on the bigger one )
Divide : big to small ( # missing on the smaller one)
