Answer:
The kitchen requires 288 sq. ft. of tile
The master bathroom requires 180 sq. ft. of tile
In total, we will spend $1170
Step-by-step explanation:
The area of the kitchen is length * width:
Area of Kitchen = sq. ft.
The area of the master bathroom is length * width:
Area of Master Bathroom = sq. ft.
- <u>Question 1: "How many square feet of tile do I need for the kitchen?"</u>
The kitchen requires 288 sq. ft. of tile
- <u>Question 2: " How many square feet of tile will I need for the bathroom?"</u>
The master bathroom requires 180 sq. ft. of tile
- <u>Question 3: "If the tile costs $2.50 per sq ft, how much money will I spend on tile?"</u>
In total, <u><em>we require sq. ft. of tiles</em></u>. If $2.50 is charged per square feet, in total we will spend:
dollars

Answer:
Step-by-step explanation:
Sample variance when large number of samples are drawn we have tend to become a normal distribution.
Variance of the sample is different since variance
Var(x) = E(x^2)-{E(x)}^2
is the formula used for finding the variance of any sample.
But sampling distribution of variance requires repeating this process with the different samples several times.
So option A is not right
B is also not correct, C is wrong
D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.
is correct
Out of 90 reservation made, 77 diners are expected to show up. And the standard deviation of this binomial distribution is 3.39
We have been given that
Percentage of people who make reservation and didn’t show up = 15% = 0.15
Number of reservation made = 90
Now we have to calculate number of people expected to show up that is we have to calculate mean. As this a binomial distribution in which we have been given
n = 90 and q = 0.15
Thus, µ = np = 90*(1-0.15) = 90*0.85
µ = 76.5 ≈ 77
Thus it is expected to have 77 diners to show up.
Now standard deviation is given as:
σ = √npq
σ = √90*0.15*0.85
σ = 3.39
Hence the standard deviation is 3.39

I believe the answer is $14.25
I took $.46 and multiplied it by 23, then I added $3.67 to that. Hope this helps :)
