Martinez town is building a volleyball court based on a scale drawing that is 40cm by 80cm and uses the scale 1 cm :22.5cm
Answers
The proportional relationship between drawing court lengths x in centimeters and court lengths in y centimeters is y = 22.5x
Your question is not complete, it seems to be missing the following information;
"write an equation for the proportional relationship between drawing court lengths x in centimeters and court lengths in y centimeters"
The drawing court length is given as;
x = 40 cm or 80 cm
drawing scale = 1 cm : 22.5 cm
The corresponding length of the court is calculated as;
when x = 40 cm;
[tex]y = \frac{22.5}{1} \times 40 cm = 900 \ cm[/tex]
when x = 80 cm;
[tex]y = \frac{22.5}{1} \times 80 \ cm = 1,800 \ cm[/tex]
The proportional relationship between drawing court lengths x in centimeters and court lengths in y centimeters is calculated as;
[tex]\frac{y}{x} = \frac{900}{40} = \frac{1800}{80} \\\\\frac{y}{x} = 22.5\\\\y = 22.5 x[/tex]
Thus, the proportional relationship between the lengths is y = 22.5x

The typing speeds for the students in a typing class is normally distributed with mean 44 words per minute and standard deviation 6 words per minute. What is the probability that a randomly selected student has a typing speed of less than 38 words per minute
Answers
Answer:
15.87%
Step-by-step explanation:
*Probability-Below 15.87%
Z1=-1
*x-1 38
*µ 44
*σ 6
The probability that a randomly selected student has a typing speed of less than 38 words per minute is 15.87%.
What is z-score?The Z-score, or standard score, is the number of standard deviations a given data point lies above or below mean.
Formula for z-scorez = (x -μ)/σ
Where,
Z is standard score.
x is observed value.
μ is mean of the sample.
σ is standard deviation of the sample.
What is probability?The area under the normal distribution curve represents probability.
According to the given question.
Mean, μ = 44
Standard deviation, σ = 6
Observed value, x = 38
Therefore, z-score = [tex]\frac{38-44}{6}= -1[/tex]
So, the are P(z > -1) = 15.87%
Hence, the probability that a randomly selected student has a typing speed of less than 38 words per minute is 15.87%.

Solve the equation for y. Then find the value of Y for each value of X.
y+7x=9;x=-1,0,2
y=?
x=?
(help i hate this math hw)
Answers
Answer:
y=9-7x
If x= -1, y=16
If x= 0, y=9
If x=2, y= -5
Step-by-step explanation:
Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.
y+7x=9
-7x -7x ---> y=9-7x
The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.
y=9-7(-1) ----> y=16
y=9-7(0) ----> y=9
y=9-7(2) ----> y=-5

XY=32, YZ=7d, and XZ=74
Answers
The value of d = 6 and the value of YZ = 42
Since XY=32, YZ=7d, and XZ=74
Based on this question, it should be noted that the addition of XY and YZ will equal to the value of XZ. Therefore,
XY + YZ = XZ
32 + 7d = 74
Collect like terms
7d = 74 - 32
7d = 42
Divide through by 7
7d/7 = 42/7
d = 6
Since d is 6, the value of YZ will be:
= 7d = 7 × 6 = 42
In conclusion, the value of d = 6 and the value of YZ = 42.
