Answer:
z = -0.816
Step-by-step explanation:
z = (x-μ)/σ
z = (4-6)/2.45
<u>z = -0.816</u>
Answer:
Step-by-step explanation:
We are given the two functions:
And we want to find:
This is equivalent to:
Then by substitution:
Evaluate:
Therefore:
Answer:
-1331
Step-by-step explanation:
Just ask. :)
If the cos A = .83 then the arc cosine of .83 equals the angle
arc cosine (.83) = 33.901 degrees
Similarly, we look up the arc cosine of .55
arc cosine (.55) = 56.633 degrees
NOW we can look up the sine of 33.901 degrees and find it is the
sine of A and it equals 0.55776
the sine of 56.633 degrees = 0.83516 and that is the sine of B
