Students surveyed boys and girls separately to determine which sport was enjoyed the most. After completing the boy
survey, it was determined that for every 3 boys who enjoyed soccer, 5 boys enjoyed basketball. The girl survey had a
ratio of the number of girls who enjoyed soccer to the number of girls who enjoyed basketball of 7:1. If the same
number of boys and girls were surveyed and 90 boys enjoy soccer, how many girls each sport?

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:
m<S' = 115
Step-by-step explanation:
A translation is when one shifts the image over on a coordinate plane. A translation doesn't affect the image itself. Hence m<S is the same as m<S'. Therefore m<S' = 115

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.
Tanya is paid an hourly rate. One week she earned $157.50 by working 30 hours. If she works 35 hours the next week, how much will she earn?
Answer:
183.75
Step-by-step explanation:
157.50
÷30
=5.25
×35
=183.75
Answer: $183.75
Step-by-step explanation: You divide $150.50 by the number of hours worked, 30 hours, to find the hourly rate. Then, you multiple the hourly rate by 35 hours.
[tex]$157.50/30 hours = $5.25/hour \\$5.25/hour * 35 hours = $183.75[/tex]
