Answer:

Step-by-step explanation:
From the figure attached,
ΔABC is an equilateral triangle.
Therefore, by the property of the equilateral triangle,
Measure of each angle = 60°
By applying tangent rule in the right triangle ADC,





Answer:
10.6 ounces
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
Given information:
Σ(x − M) = 44
where, M is mean.
Sample size = 12
The computational formula for sample variance is

where, M is sample mean and N is sample size.
Substitute Σ(x − M) = 44 and N=12 in the above formula.



The sample variance is 4.0.
Therefore, the correct option is B.
Answer:
yes, that is very correct
