8x = 44 -4
8x = 40
x = 40/8
x = 5
Answer:
64 and 81
Step-by-step explanation:
<span>The variance method is as follows.
-Sum the squares of the values in data set, and then divide by the number of values in data set
- From that, subtract the square of the mean (add all values and divide by number of values in the data set)
Our variance is
<span>
Since variance has to be 14, we set
and solve for m
quadratic formula
-4 doesnt' work as it is not a positive integer
m = 11

Answer:
6.33 m
Step-by-step explanation:
Total length of the rope = 8 m
Cut length of the rope = 1.67 m
We need to find the remaining piece of the rope.
Remaining piece = Total length - cur length
= 8 m - 1.67 m
= 6.33 m
So, 6.33 m is the remaining piece of the rope.
Answer: q = -13
Step-by-step explanation:
(q+5)/4 = -2 first you multiply 4 to remove denominators
(q+5) = -8 then subtract 5
q = -13
