STatiana [176]

Answer:

C.

Mean= 4.9

Mean Absolute Deviation (MAD): 4.099173553719

Step-by-step explanation:

An outlier is a value that is very different from the other data in your data set. This can skew your results. As you can see, having outliers often has a significant effect on your mean and standard deviation. Because of this, we must take steps to remove outliers from our data sets.

outlier: 21

Please give me correct answer and fast answer it if know answer only
Stolb23 [73]

Answer:

Approximatley 5.8 units.

Step-by-step explanation:

We are given two angles, ∠S and ∠T, and the side opposite to ∠T. We need to find the unknown side opposite to ∠S. Therefore, we can use the Law of Sines. The Law of Sines states that:

\frac{\sin(A)}{a}=\frac{\sin(B)}{b} =\frac{\sin(C)}{c}

Replacing them with the respective variables, we have:

\frac{\sin(S)}{s} =\frac{\sin(T)}{t} =\frac{\sin(R)}{r}

Plug in what we know. 20° for ∠S, 17° for ∠T, and 5 for <em>t</em>. Ignore the third term:

\frac{\sin(20)}{s}=\frac{\\sin(17)}{5}

Solve for <em>s</em>, the unknown side. Cross multiply:

\frac{\sin(20)}{s}=\frac{\sin(17)}{5}\\5\sin(20)=s\sin(17)\\s=\frac{5\sin(20)}{\sin(17)} \\s\approx5.8491\approx5.8
