Answer: y ≈ 10.6 cm
Step-by-step explanation:
The cosine function relates the adjacent side to the hypotenuse in a right triangle. The side adjacent to the 20° angle is 10 cm.
cos(20°) = (10 cm)/y
y = (10 cm)/cos(20°)
y ≈ 10.6 cm
<span>The first person can have any birthday. That gives him 365 possible birthdays out of 365 days, so the probability of the first person having the "right" birthday is 365/365, or 100%.The chance that the second person has the same birthday is 1/365. To find the probability that both people have this birthday, we have to multiply their separate probabilities. (365/365) * (1/365) = 1/365, or about 0.27%.</span>
Answer:
70
Step-by-step explanation:
Ok so we first add 4.75 and 5.25. 4.75+5.25=10. So 10 hours each day so 10 x 7 = 70. 70 hours in 7 days

Answer:
1 / 7
Step-by-step explanation:
Number of sections on spinner = 7
Section is numbered 1 to 7
Since the probability of landing on each section is the same:
Probability that spinner lands on 4 :
Probability, p = Required outcome / Total possible outcomes
Required outcome = landing on 4 = 1
Total possible outcomes = (1 to 7) = 7
P(landing on 4) = 1 /7
