Answer:
Range = 7
Mean = 7.75
Assumption: Most students will have 7 or 10 letters in their last name
Step-by-step explanation:
Range = Largest - Smallest
= 10 - 3
= 7
Mean = Add the total numbers up to get a total / numbers in the series
= (3+5+2(6)+2(9)+5(7)+4(8)+5(10)) / (1+1+2+5+4+2+5)
= 7.75
Answer:x = (5 + 3/7) - (2 + 1/5)*x
112x = 190
x = 95
56
≈ 1.696429
Answer:
y = 1/4x + 7
Step-by-step explanation:
A perpendicular line will have an opposite reciprocal slope, so the slope will be 1/4
Plug in the given point and slope into y = mx + b, then solve for b
y = mx + b
5 = 1/4(-8) + b
5 = -2 + b
7 = b
Plug in b and the slope into y = mx + b
y = 1/4x + 7
So, the equation of the line is y = 1/4x + 7
