Answer:
* 60 -$60 <- answer
* 45- $45 <- answer
94.5- $94.50 <- answer
Step-by-step explanation:
40%= 0.4 ×150=60
30%=0.3×150=45
60 +45= 105
(105*10)/100= 10.50
105-10.50=$94.50 <- answer
Okay. What you have to do is add all of the numbers shown.
103+36+33
Once you have gotten your answer(172) you must subtract that number with 180.
The answer is 8.
Answer:
64c15 - 0.027.
Step-by-step explanation:
That would be 64c15 - 0.027
= 4c^5 - 0.3.
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98
<h3>What is a sample size?</h3>
The sample size is a term used in market research for defining the number of subjects included in a sample size. By sample size, we understand a group of subjects that are selected from the general population and is considered a representative of the real population for that specific study.
Empirical rule states that for a normal distribution, 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean.
For a population mean of 20.15 and a standard deviation of 3.7
68% are within μ ± σ/√n,
hence,
68% = 20.15 ± 3.7/√20 = (19.32, 20.98)
For a sample size of 20 players, 68% of the sample means fall within 19.32 and 20.98.
