Answer:
46.22
Step-by-step explanation:
Class A total= 23 x 13= 299
Clas B total= 57 x 28= 1596
total score= 299 + 1596 = 1895
total mean= 1895 ÷ (13+28) = 1895 ÷ 41
= 46.22
It would be 2m because each ticket is 2 dollars and then you have to multiply it by the number of tickets you are buying M
Answer:
3x + 12
Step-by-step explanation:
Distribute the 3
Finding the sample size for estimating a population proportion.
The formula is:
n = (z/m)^2 p~(1−p~)
where:
Z is the z value of the confidence level where 95% is equal to 1.96
M is the margin of error where 0.05
And p~ is the estimated value of the proportion where it is 0.50
Solution:
n = (1.96/0.05)^2 (0.5) (1-0.5)
= 1.536.64 (0.5) (0.5)
= 768.32 (0.5)
= 384.16
This is the minimum sample size, therefore we should round it up to 385. The answer is letter c.
The interest due on the first payment is
.. I = Prt
.. I = 110,000*.055*(1/12)
.. I = 504.17
Then the decrease in principal resulting from the first payment is
.. 568.00 -504.17 = 63.83
and the new balance is
.. $110,000.00 -63.83 = $109,936.17
