Answer:
The missing number would be 22.
Step-by-step explanation:
The missing number would be, lets say <em>x</em>.
(<em>x</em> - 8) / 7 = 2
First, lets multiply 2 by 7.
2 * 7 = 14
Next, lets add 8 to 14.
8 + 14 = 22
The missing number would be 22.
To check this answer, subtract 8 from 22 which would be 14.
Then divide by 7 which would be 2. This answer is correct.
Therefor, the missing number, or x, would be 22.
Hope this helps!

Step-by-step explanation:
One hack that I used is I looked at all of the options in the first row and added the number one less 6 times
I basically did
5+(5-1)+(5-2)+(5-3)+(5-4)
5+4+3+2+1

2 1/2 yards = 7.5 ft
1 foot and 6 inches = 1.5 ft
7.5-1.5 = 6
6 ft = 72 inches

Answer: (30.49 years, 42.31 years)
Step-by-step explanation:
The formula to find the confidence interval is given by :-
, where 
= Sample mean
z* = Critical value.
= Population standard deviation.
n= Sample size.
As per given , we have
n= 40
We know that the critical value for 99% confidence interval : z* = 2.576 (By z-table)
A 99 percent confidence interval for µ, the true mean age of guests will be :
∴ a 99 percent confidence interval for µ, the true mean age of guests = (30.49 years, 42.31 years)
