rAnswer:
50%
Step-by-step explanation:
7 nurses
3 doctors
4 offices
14 in total
7/14 or 50% is the probability
Answer: $45451
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 25000
r = 3% = 3/100 = 0.03
n = 4 because it was compounded 4 times in a year.
t = 20 years
Therefore,
A = 25000(1+0.03/4)^4 × 20
A = 25000(1+0.0075)^80
A = 25000(1.0075)^80
A = $45451
Answer:
5.6
Step-by-step explanation:
Given :
Quality rating for 8 movies :
5.6, 7.9, 7.0, 5.9, 7.8, 6.2, 6.4, 5.2
Let rating for the 9th movie = x
Average quality rating olfor the 9 movies = 6.4
To find x :
Sum of all ratings / number of ratings = 6.4
(5.6 + 7.9 + 7.0 + 5.9 + 7.8 + 6.2 + 6.4 + 5.2 + x) / 9 = 6.4
(52 + x) / 9 = 6.4
52 + x = 57.6
x = 57.6 - 52
x = 5.6
