If sin(6m-8) = cos (2m), find the value of m.
Gala2k [10]
   
We believe that the angles are in quadrant 1.

<span>sin(6m-8) = cos (2m)

</span>⇒  6m-8 = 90 - 2m
<span>
6m + 2m = 90 + 8

8m = 98

m = 98 / 8 = 12.25

3. The Round Rock Express has a pitcher with an impressive winning record. Opposing teams are attempting to analyze his pitches.
Maurinko [17]

Answer:

0.66

Step-by-step explanation:

Given:

Let P(Throwing strike) = 0.35

So,

P(S') = 1 - 0.35 = 0.65

P(A / B) = P(A and B) / P(B)

P(Throwing fastball and thrown strike) = P(F / S) = 40% = 0.4

P(Throwing fastball  not thrown  strike) = P(F / S') = 80%

P(Throwing fastball  not thrown  strike) =0.8

So,

P(F and S) = 0.8 x 0.65

P(F and S) = 0.52

P(F) = [P(F / S) x P(S)] + [P(F / S') x P(S')]

= (0.4 x 0.35) + (0.8  x 0.65)

= 0.14 + 0.52

= 0.66
