To find a mean, you total all numbers, then divide by the quantity of numbers.
=(14+14+12+16+6+11+8)/7
=81/7
=11.571 = 11.6 lbs. rounded
Hope this helps! :)
Answer: B. (1,1)
Step-by-step explanation: If you find slope with the points (0,-1) and (1,1) you will get a slope of 2.
the formula you can use is y2-y1/x2-x1
substitute the values with the 2 points i mentioned
1-(-1)=2
1-0=1
divide 2/1
and you get 2
So B, (1,1) would be your answer.

Arc length is equal to radius multiplied by the central angle in radians not degrees
In order to identify the mean distance jogged by Jim for 6 days, we add up all of the distances and divide the sum by 6. That is,
sum = 6.5 + 5 + 3 + 2 + 3.5 + 4 miles
sum = 24 miles
Dividing the sum by 6 will give us an answer of 4 miles. Thus, Jim jogged an average of 4 miles for 6 days.
