Answer:
4
Step-by-step explanation:
3*10=10+5s
30 = 10 + 5s
30-10 = 5s
or, 20/5= s
or, 4 =s
therefore the value of s is 4.
thank you
1.25 - 0.5 = 0.75
1.25 hours = 1 hour 15 minutes
0.5 hours = 30 minutes
1 hour 15 minutes - 30 minutes = 45 minutes
Using the <u>Central Limit Theorem</u>, the statement is false, as for the averages of the data values for a sample group, the standard error is
, hence, the formula is:

While for a single value, it is:

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
Hence, the formulas are different, and for an average of the data values for a sample group it is:

Answer:

Step-by-step explanation:
We can solve the equation
by isolating the variable x on one side. To do this, we must simplify the equation.

Combine like terms:

Add 1 to both sides:

Divide both sides by 13:
