Answer:slope =7/10
Step-by-step explanation:
slope=(y-y0) ➗ (x-x0)
Slope=(8-1) ➗ (4-(-6))
Slope=7 ➗ (4+6)
Slope=7 ➗ 10
Slope=7/10
Answer:
7m
Step-by-step explanation:
Let m be the miles he jogs each day
No. of days in a week = 7
He jogs in 1 day = m miles
He jogs in 7 days = m times 7 = 7m
Answer:
mean = 77
Step-by-step explanation:
We have a confidence interval of (59, 95) with a confidence of 99.7 percent
99.7 is 6 standard deviations from the mean, 3 on each side of the mean
mean - 3 sigma = 59
mean + 3 sigma = 95
We can use elimination to eliminate sigma. Add these equations together
mean - 3 sigma = 59
mean + 3 sigma = 95
---------------------------------
2 * mean = 154
Divide each side by 2
2 * mean/2 = 154/2
mean = 77
