\sin(\alpha) =  \dfrac{\text {opp}}{\text{hyp}}

\sin(\alpha) =  \dfrac{\text {1}}{\text{2}}

\alpha =  \sin^{-1} \bigg ( \dfrac{1}{2}  \bigg)

\alpha = 30 \textdegree

Answer: 30°

You are researching the average emails received per day. You want to know how many employees you should survey if you want to kn
IrinaK [193]

Answer:

The value is  n =29 \ employees

Step-by-step explanation:

Generally the number of employee to survey(sample size) is mathematically represented as

       n = [ \frac{z *  \sigma }{E} ]^2

Here E is the margin of error which is given as E = 47

So substituting 1.645 for z and   155 for  \sigma

     n = [ \frac{1.645 *  155 }{47} ]^2

=>    n =29 \ employees

HELP!!!!!!!!!!!!!!!!!!!!!!!!! Which scatter plot shows a negative association and an outlier?
sweet [91]

A negative association shows that the points are decreasing, as one variable increases, the other variable decreases. The outlier will be a point that strays away from the other points

Option D is your answer, it would not be C because the point is still close to the other points while the point in D is not even close
