Answer:
dang nice
Step-by-step explanation:
Answer:
Mean $1060
Standard error $34.69
Step-by-step explanation:
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, which is also called standard error,
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Population:
Mean $1,060 and standard deviation $190.
Sampling distriution of samples of size 30:
Mean $1060
Standard deviation ![s = \frac{190}{\sqrt{30}} = 34.69](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B190%7D%7B%5Csqrt%7B30%7D%7D%20%3D%2034.69)
Here are three ratios that equivalent to 18:4
9:2
36:8
54:12
hope this helped!
p.s. may i please have the branliest answer?
9n + 27 = 7n -3
2n + 27 = -3
2n = -30
n = -15
The following integer values of x satisfy the given inequality,
4, 5, 6, 7, 8
What is an inequality?
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made using inequality.
Solving the Inequality
The given inequality is,
5x + 4 > 19
5x > 19 - 4
5x > 15
x > 15/5
x > 3
So, the required values of x must be greater than 3 in the given interval, [2,8]
Thus, the integer values of x in the the interval [2,8] that satisfy the given inequality are 4, 5, 6, 7 and 8 (∵ Square brackets of an interval denote inclusion of the terminal values).
