HELP Barry weighed 145 lbs in 2006 and weighs 190 lbs today (2020). What was the rate
of change in weight?

45lbs

Step-by-step explanation:

Because 190lbs (2020 weight) - 145lbs (2006 weight) = 45lbs

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
