Answer:
3(3x^2 + 5)
Step-by-step explanation:
step 1: find out the greatest common factor (GCF) of the number 9 and 15
ex: 9x^2 + 15x (3 * 3x^2 + 3 * 5)
step 2: factor out the common term 3
ex: 3 * 3x^2 + 3 * 5 (3 * 3x^2 + 5)
step 3: simplify the equation
3 * 3x^2 + 5 [3(3x^2 + 5)]
Answer:
You can use dots, tallys or pictures
Step-by-step explanation:
Answer: (3.46, 3.62)
Step-by-step explanation:
The formula to find the confidence interval for population mean is given :-
, where n = sample size.
= Two-tailed t-value for significance level of and degree of freedom df= n-1.
= sample standard deviation.
As per given , we have
mm
s= 0.20 mm
n= 25
Significance level
Since population standard deviation is not given , it means the given problem has t- distribution.
Two-tailed t-value for significance level of and degree of freedom df= 24:
95% Confidence interval for population mean:
Hence, the 95% two-sided confidence interval for the mean glass thickness = (3.46, 3.62)
Answer:
19ft
Step-by-step explanation:
The answer is 19 ft.
You would multiply 5 and 6 which equals 30
Then, divide 570 by 30 which equals 19.
