Cosine of angle A is also x

This is because the sine is opposite over hypotenuse and cosine is adjacent over hypotenuse so both sine and cosine in this example are asking for the same side over the hypotenuse which means cosine of angle A will be the same as sine of angle B

I believe this is correct but I may be wrong, let me know what it ends up being!

In a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10, and the mean is M = 6. If the largest sco

Murrr4er [49]

Answer:

Step-by-step explanation:

Given that in a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10

Mean = 6

Since mean = 6 we get sum of all the 6 scores = $6(6) = 36$

Now II part says 10 is changed to 20

i.e. original sum = 36

Changed value = 10

Adjusted value =26

Add: new value =22

New sum =48

So we have sum = 48

New mean= $\frac{48}{6} =8$

(This can also be done using the formula

old mean + positive change in one score/6)
