Answer:
Mean= 13.38
Median= 15
Step-by-step explanation:
The mean can be calculated by getting the sun of the 8 scores and then dividing it by the number of students
Mean= 7 + 18 + 18 + 15 + 17 + 10 + 15 + 7/8
= 107/8
= 13.38
The median can be calculated by first rearranging the numbers from the lowest to the highest and then calculating the average of the two middle numbers
7 , 7, 10, 15, 15, 17, 18, 18
Median = 15+15/2
= 30/2
= 15
Hence the mean is 13.38 and the median is 15
Answer:
Vertex: (5, -9)
Step-by-step explanation:
fix = (x-8)(x-2)
fix = x^2 - 2x - 8x + 16
fix = x^2 - 10x + 16
a = 1, b = -10, and c = 16
To find vertex:
x = -b/2a
x = -(-10)/2(1)
x = 10/2
x = 5
y = 5^2 - 10(5) + 16
y = 25 -50 + 16
y = -9
Vertex: (5, -9)
When x is 1 and y is 10
x(10) = y
When x is 2 and y is 12
x(6) = y
when x is 4 and y is 16
x(4) = y
When x is 6 and y is 20
x(4) - 4 = y
hope this helps
<u>Answer</u>
C = 12
<u>Explanation</u>
Ratio is a division. For the two ratios to be proportional, then they must be the same after been simplified to their simplest form.
7/C = 35/60
35 has been divided by 5 to get 7. 60 must also be dived by 5 for the ratios to be proportional.
60 ÷ 5 = 12
∴ C = 12.
7/12 = 35/60
