If it’s only reflected over the y axis then only the x values change
Answer:
x = 75
Step-by-step explanation:
x/5 = 15
x = 75 Multiply 5 on both sides
Answer:
Tobias did best on the aptitude test.
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For Emilio
Emilio got a score of 76; this version has a mean of 70.6 and a standard deviation of 9.
z = (x-μ)/σ
z = 76 - 70.6/9
z = 0.6
For Alissa
Alissa got a score of 298.8; this version has a mean of 282 and a standard deviation of 24.
z = (x-μ)/σ
z = 298.8 - 282/24
z = 0.7
For Tobias
Tobias got a score of 8.04; this version has a mean of 7.2 and a standard deviation of 0.4.
z = (x-μ)/σ
z = 8.04 - 7.2/0.4
z = 2.1
Looking at the calculated z score above, we can see that Tobias did better on his aptitude test because he had a higher z score compared to Emilio and Alissa.
First, I will add up the know amount of points Chef Curry scored
45 + 48 + 32 + 40 = 165
To find the mean, add up all the numbers and divide that by how many values you had
I know 210 / 5 = 42, so I will subtract:
210 - 165 = 45
Cheer Curry scored 45 points
