<u>old:</u> $16
<u>new:</u> $20
<u>percent increase</u>
-> formula: (new-old / old) x 100
(20-16 / 16) x 100
4/16 x 100
0.25 x 100
answer: 25% increase
90 attempts are made and only one third are successful. Multiply the attempts by successes and you get 30 successful shots (90 x 1/3= 30).
Answer:
Step-by-step explanation:
Here is one example:
Answer:
(0.30, 0.42)
Step-by-step explanation:
Given the sample proportion is = 0.36
Number of trials required for determining the margin of the error = 100
Sample size, n = 50
The point estimate = 0.36
The minimum sample proportion form the simulation = 0.28
The maximum sample proportion from the simulation = 0.40
Also the margin of the error of population proportion is found by using the half of the range.
Therefore, the interval estimate for the true population proportion is = (0.30, 0.42)
Answer:
The approximate value of the investment in one year is 4183.
Step-by-step explanation:
The formula for finding the compound interest for one year that compounded quarterly is :
Here,
P - Principal = 4000
r - 4.5%
t - 1
Therefore,
= 4183.08
Hence, the approximate value of the investment in one year is 4183.
