Hi there!
Since angles 3 and 7 are corresponding angles, they are also congruent. This means that angle 3 is equal to angle 7. Therefore, the correct answer is C, 120 degrees.
Answer:
A. A binomial distribution with n=25 and p=0.58
Step-by-step explanation:
We're looking at the number of tails, not the proportion. The probability of tails is 0.58, and the number of tosses is 25.
Answer:
E. 1/2
Step-by-step explanation:
Divide by 2, then make use of the Pythagorean identity for sine and cosine.
sin(x)^2 +cos(x)^2 = 2a
1 = 2a . . . . . . . sin²+cos²=1
1/2 = a
