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.

Choose all of the correct statements.
Answer:
1. The diameter is 2 times the Lenght of the radius.
2. C = πd
3. π = C/d
4. d = C/π
5. The circumference is 3.14 times the diameter.
Step-by-step explanation:
Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:
d = 2r
From:
d = 2r
Divide both side by 2
r = d/2
The radius is half the diameter.
Circumference (C) of a circle is given by:
C = 2πr
C = π2r
Recall:
d = 2r
C = πd
C = πd
Divide both side by d
π = C/d
C = πd
Divide both side by π
d = C/π
C = πd
π = 3.14
C = 3.14 × d
Thus, the circumference is 3.14 times the diameter.
SUMMARY:
The correct statement from the above illustration is given below:
1. The diameter is 2 times the Lenght of the radius.
2. C = πd
3. π = C/d
4. d = C/π
5. The circumference is 3.14 times the diameter.
