in may there were 157 people living in Kristins neighborhood, by august the population had increased 21% how many people were in kristins neighborhood by august

Step-by-step explanation:

It’s B because 21% of 157 is 32.97 which then you would then add with the 157 people already there and get 189.97 and since you cannot have .97 of a person you round it up to 190

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
