Answer:
Step-by-step explanation:
recall law of Sines Sin(A) /a = Sin(B) / b
for this question
F = A = 105 and a = 37
E = B and b = 28
then plug those into our law of Sines equations
Sin(105) / 37 = Sin(B) / 28
0.025846 = Sin(B) / 28
28 * 0.025846 = Sin(B)
0.72369 = Sin(B)
arcSin(0.72369) = arcSin ( Sin ( B ) )
46.3599 = B
E = 46° ( rounded to the nearest degree)
Step-by-step explanation:
First, find the degrees of freedom:
df = n − 1
df = 49
To find the p-value manually, use a t-score table. Find the row corresponding to 49 degrees of freedom. Then find the α column that corresponds to a t-score of 1.421. You'll find it's between α = 0.10 (t = 1.299) and α = 0.05 (t = 1.677). Interpolating, we get an approximate p-value of 0.084. For a more accurate answer, you'll need to use a calculator.

I'm guessing this is the question you meant to ask:
Eight hundred tickets were sold for a movie production and the receipts for the performance wear $8600. The tickets for adults and students sold for $12.50 and $7.50, respectively. How many of each ticket were sold?
Answer:
a
Step-by-step explanation:
the equation for a circle centered at orgin is x^2+y^2=r where r is the radius. multiplying, adding, or subtracting any numbers to the x and y components such as the other choices here causes the circle to be translated about the graph.
The answer is 18 equal line segments are needed to make 6 triangles.
