Hello!
Slopes of perpendicular lines are opposite reciprocals of each other, which the slope of line perpendicular to a line with a slope of 7/8 is -8/7.
Answer:
D. -8/7
Hope this helps!
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
Answer: The percentile rank for Park Street's revenues for the week is 60th.
The percentile rank for Bridge Road's revenues for the week is 73rd
Step-by-step explanation:
Given data:
Park street revenue = $7,500
Mean = 6611
SD = 3580
N = 36
Bridge road revenue = $7,100
Mean = 5989
SD = 1794
N = 40
Solution:
where X = observation, µ = mean, σ = standard deviation.
Zscore = (X – µ) /σ
For Parker street
Zscore = (X – µ) /σ
= 7500 – 6611 / 3580
= 0.25
Percentile rank
P(Z < 0.25 ) = 0.5987
= 60%
Percentile rank for the week is 60%
For Bridge road
Zscore = (X – µ) /σ
= 7100 – 5989/ 1794
= 0.62
Percentile rank
P(Z < 0.62) = 0.7324
= 73%
Percentile rank for the week is 73%
