yes sure, i learned this before so
1. a. make a proportion here, of percentage.
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again,
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
Answer:
D. p = 6.25h
Step-by-step explanation:
6.25 (2) = p 12.50
6.25 (4) = p 25.00
6.25 (6) = p 37.50
6.25 (8) = p 50.00
Answer:
The mean is 95 and the standard deviation is 2
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Population:
Mean 95, Standard deviation 12
Samples of size 36:
By the Central Limit Theorem,
Mean 95
Standard deviation ![s = \frac{12}{\sqrt{36}} = 2](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B12%7D%7B%5Csqrt%7B36%7D%7D%20%3D%202)
Answer:
5.291 feet
Step-by-step explanation:
I used pythagorus thoery
Answer:
$6,400.00
Step-by-step explanation:
Following the rule of PEMDAS,
exponents go first in this scenario.
10^7 = 10000000
2.56*10000000 = 25600000
Then, divide the amount of money by the number of employees.
25600000/4,000 = 6400
Each employee would receive $6,400.00
