the weight of an organ in adult males has a bell-shaped distribution with a mean of 320 grams and a standard deviation of 20 grams. us
(a) about 68% of organs will be between what weights?
(b) what percentage of organs weighs between 280 grams and 360 grams?
(c) what percentage of organs weighs less than 280 grams or more than 360 grams?
(d) what percentage of organs weighs between 300 grams and 360 grams?

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

answer: the correct answer is -32

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392

2: 10
