For a binomial distribution the Mean is equal to np and the Variance is npq.
If n = 346 and p = 0.2 , what is the Standard Deviation?

7.44

Step-by-step explanation:

formula for SD is since we dont have q, we find q by (1-p)

so now its or

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
