Answer:
y = -4x + 17
Step-by-step explanation:
Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.
Answer:
1.1 mph
Step-by-step explanation:
Step one:
John swims a distance of 5/12 miles
time taken = 3/8 of an hour
Required
The speed with which John swims
Step two:
speed= distance/time
substituting we have
speed= 5/12/3/8
multiply the numerator by the inverse of the denominator
speed= 5/12*8/3
speed= 40/36
speed= 1.1 mph
Answer:
Mean = 12.85714
Median = 15
Range = 15
Step-by-step explanation:
Mean:
5 + 15 + 10 + 20 + 15 + 10 + 15 = 90
90 / 7 = 12.85714
Median:
5, 10, 10, 15, 15, 15, 20
Median = 15
Range:
20 - 5 = 15
