Answer: 1,400 calories
Bianca jogged 1.25 miles per day for 8 days. so 1.25*8 would equal 10 miles.
Since she jogged 10 miles and burned 140 calories per mile, if we multiply 10*140, we would get 1,400.
So last month, she lost 1,400 calories.
Answer:
A) Mean = 135 Variance = 62 Standard Deviation = 8
Step-by-step explanation:
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8
