Answer: 2.460
Step-by-step explanation:
The formula of Margin of Error for (n<30):-
Given : Sample size : n= 18
Level of confidence = 0.90
Significance level :
Using the t-distribution table ,
Critical value :
Standard deviation:
Then, we have
Hence, the margin of error (ME) of the confidence interval with a 90% confidence level = 2.460
Answer:
x = 8
Step-by-step explanation:
13 - 5 = 8
x = 8
hope this helps...
That's a monomial; it has one variable, one coefficient, and one degree.
You would have to use fractions
Firstly, foil 2(4z - 1) and 3(z + 2):
Next, subtract 3z on both sides:
Next, add 2 on both sides:
Lastly, divide both sides by 5, and your answer will be
