Answer:
(C) Elijah’s prediction is high because 180 times one-fourth = 45.
Step-by-step explanation:
Because the spinner is divided into 4 equal sections, they all have an equal chance of being landed on. Therefore, you must do 180*1/4 which is 45. This means that's Elijah's prediction of 60 of the spins will result in 3 is too high.
Answer
After 13.15 years the population of both towns will become equal.
Step-by-step explanation:
Population of the city Anville is given by using the compound interest formula
The formula of compound interest
A = p( 1+r/n)^n*t
using this we get
P1 = 16000 (1 +
) ^1*t
Population of the city of Brinker will be
P2 = 11000( 1 + 
) ^1*t
now to make equal population in both towns
P1=P2
16000 (1 +) ^1*t = 11000( 1 + ) ^1*t
t = 13.15 years
Exactly 10,000 it’s hard to explain though it’s really complicated
