Answer:
Step-by-step explanation:
8 .) Probability of students has no pets in senior = No. of outcomes favourable / Total no.of outcome
= 15 / 24
9.) Probability of students has pets in junior = No.of outcomes favourable / Total no. of outcomes
= 37/52
The value would be $2.53 million.
Set up a proportion to solve this:
7.6/78 = x/(78-52)
[7.6 million for 78 years; x million for 78-52 years remaining]
Cross multiply:
7.6(78-52) = x*78
7.6(26) = 78x
197.6 = 78x
Divide both sides by 78:
197.6/78 = 78x/78
2.53 = x
Cos(x) = 32/40 = 0.8 ⇒ x ≈ 37°
The smallest angle that the terminal side with a given angle makes with the x-axis
