Answer:

1

Step-by-step explanation:

A coin only has two outcomes. Meaning that she has a 50/50 chance of landing on each side. So, 50% of 20 is 10. According to the theoretical  probabilty, the coin would have landed on heads 10 times and tails 10 times. So, for that to be true Maria would have had to land on tails one more time.

When the bridge is fully raised, tan⁡ θ=5/12. What is sec ⁡θ? PLEASE HELP
lbvjy [14]

Answer:

sec Ф = 13/12

Step-by-step explanation:

If tan Ф = 5 / 12, we can find the third side of this triangle (that is, the hypotenuse) by applying the Pythagorean Theorem:  

hyp² = 5² + 12² = 169.  Thus, the hyp is 13.

Thus, cos Ф = adj / hyp = 12/13.

The secant function is the reciprocal of the cosine function, so

sec Ф = 13/12.
