Question 1 of 10, Step 1 of 1 Correct
The Magazine Mass Marketing Company has received 18 entries in its latest sweepstakes. They know that the probability of receiving a magazine subscription order with
an entry form is 0.5. What is the probability that more than 4 of the entry forms will include an order? Round your answer to four decimal places.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
