Answer:
2
Step-by-step explanation:
this is a 30-60-90 Δ and the ratio of the sides are 1 : 
: 2
1 / 2 = / x
cross-multiply: x = 2
It would be 2800*0.04*4. Your final answer will be $448
Answer:
so the answer is 95°
Step-by-step explanation:
The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
Answer: The central limit theorem tells us that when random samples are chosen the results tend to approach a normal distribution.
The basic idea is that the more random samples that you select, the closer you should get to the mean. In most cases, 30 or more samples is regarded as a large enough sample to get close to the mean. Our sample is 48, so we should be close to the mean.
As we are given with
we are supposed to simplify this expression. which can be done as below
