Answer:
D. 157°
Step-by-step explanation:
∠EFB and ∠AFB form a linear pair, so are supplementary.
∠EFB = 180° - ∠AFB = 180° -23°
∠EFB = 157°
Use a unit rate! You can use the rate assignments/hour, meaning how many assignments will you do every hour. This can be written as 8/5 (assignments/hours), or 8/6 (depending on how many hours you give yourself. If you wanted to simplify. you could divide the fractions.
8/5 would become 1.6 (1.6 assignments per hour)
8/6 would become 4/3 (4/3 assignments per hour)

Answer: 0.6763 cm∧2
Step-by-step explanation: Variance is one of the measures of dispersion which is the the second central moment in probability. It is defined as a measure of by how much the values in a data set differs from the mean of the values. Thus it is the average of the squares of the deviations from the mean as this ensures that both the negative and positive deviations do not cancel each other out.
The sample variance would be calculated as follows:
Population size is 7 (5.6 4.9 6.0 5.1 5.5 5.1 7.5)
Mean: Sum of samples / population size ;
(5.6 4.9 6.0 5.1 5.5 5.1 7.5) / 7 = 5.67
Applying the formula for variance: [ Summation (x - mean) ] / population size =( |5.6 - 5.67| + |4.9 - 5.67| + |6.0 - 5.67| + (|5.1 - 5.67|) * 2 + | 5.5 - 5.67| + |7.5 - 5.67|) / 7 = 0.6763 cm^2
