Patty's Pavers has determined that a paver measuring 5 inches long has a z-score of +1 and a paver measuring 5.25 inches long has a z-score of +2.
Hi! I need Help!
What is the mean length of the pavers produced at Patty's Pavers?
4.25 inches
5.25 inches
4.75 inches
5.75 inches
Thank you!
Answer:
4.75
Step-by-step explanation: given x=5 inches Z-score =1 let 'X' be the variable in normal distribution z=+1 when x=5 inches.
The mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.
What is Z-score?A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,
[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]
Where Z is the Z-score,
X is the data point,
μ is the mean and σ is the standard variable.
The Z-score of +1 is,
(x-μ)/σ = 1
(5-μ)/σ = 1
5 - μ = σ
The Z-score of +2 is,
(5.25-μ)/σ = 2
(5.25 - μ)/σ = 2
5.25 - μ = 2σ
Substitute the value of the 'σ', therefore, standard deviation from the above,
5.25 - μ = 2(5 - μ)
5.25 - μ = 10 - 2μ
5.25 - 10 = -2μ + μ
μ = 4.75
Hence, the mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

Answer:
Length = 11 1/3 ft; Width = 4 2/3 ft
Step-by-step explanation:
First question:
The length is 2 more than twice the width, so
L = 2W + 2
Second question:
2L + 2W = 32
L = 2W + 2
Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.
2L + 2W = 32
2(2W + 2) + 2W = 32
4W + 4 + 2W = 32
6W = 28
W = 28/6 = 14/3 = 4 2/3
L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3
L = 11 1/3
W = 4 2/3
Answer: Length = 11 1/3 ft; Width = 4 2/3 ft
