Answer:
2.15%
Step-by-step explanation:
If you were to get the z-score for both 500 and 550 and then get the probability of both those z-scores. After getting the probability you would subtract both probability and get your answer.
Z-score:
550-400/2=3
500-400/2=2
Probability:
3 (from the Z-table) is .9987
2 (from the Z-table) is .9772
.9987-.9772= .0215
.0215 as a percentage is 2.15%
Answer:
I'm pretty sure it's 1,1.
Step-by-step explanation:
Answer:
170,070 residents
Step-by-step explanation:
Original population = 1500 residents
Total population after 6 years is calculated using the formula
A = P(1+r)^t
r is the rate = 120% = 1.2
t is the time = 6 years
P is the original population
A = 1500(1+1.2)^6
A = 1500(2.2)^6
A = 1500(113.379904)
A = 170,069.856
The cost will be <u>$20.40</u>
<h3>
EXPLANATION</h3>
10% of $28 = $2.80
10% x 2 = $5.60 = 20%
$5.60 + $2 = $7.60
$28 - $7.60 = <u>$20.40</u>
Hope this helps!
