PLEASE HELP 1. The mass of potatoes sold loosely in a supermarket bin are normally distributed with a mean of 372 grams and a standard deviation of 6.3 grams. The bin contains 164 potatoes. (a) How many of the potatoes in the bin are expected to have a mass of 380 grams or more? Round your answer to the nearest whole number. (b) What percent of the potatoes in the bin are expected to have a mass of less than 360 grams? Round your answer to the nearest tenth of a percent. (c) What is the probability that a potato randomly selected from the bin will have a mass of at least 370 grams? Round your answer to the nearest tenth of a percent.

2. A and B are two events. P(A)=0.45, P(B)=0.2 and P(A and B)=0.65
Are the events independent?
Use the concept of conditional probability to support your answer.

understand that i don't know the answers

will someone answer his question

table 3 represents a direct variation function. : )

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
