Answer:
Mean Deviation = 5
Step-by-step explanation:
The numbers are given as;
8, 12, 12, 25, 10, 14, 4, 3, 22, 10
Mean = Sum of numbers / Population = 120 / 10
Mean = 12
mean deviation involves finding the sum of the absolute values of the differences between the individual elements and the mean. Then divding by the population.
Mean Deviation = |(8 - 12) + (12 - 12) + ( 12 - 12) + (25- 12) + (10- 12) + 14- 12) + (4- 12) + (3 - 12) + (22- 12) + (10- 12)
| / 10
Mean Absolute Deviation = 5
Answer:
The cost has been reduced by approximately 33%.
Step-by-step explanation:
1% of 120 is 1.2.
80 divided by 1.2 is 66.66666666...
Meaning that $80 is about 66% of the original cost. Therefore, about 33% of the cost was removed.
Hope this helps
Answer:
5/13
Step-by-step explanation:
Cosine ratio for an angle is defined as the ratio of Adjacent side to Hypotenuse.
We have to find the cosine ratio for angle F. The side adjacent to angle F is side GF and the hypotenuse of the triangle is side FH. The side opposite to the right angle is always the hypotenuse.
So, we can write:
Therefore, the cosine ratio of angle F is 5/13
Answer:
A
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 100 = 256
a^2 = 156
a = 12.48
a = 12.5
