Answer:
61.5%
Step-by-step explanation:
Let's find all the demographics first:
Sophomores in the class(total 15):
Female: 5
Male : 10
Freshmen in the class(total 11):
Female: 3
Male: 8
There are 11 freshmen(male and female) and 5 female sophomores. Thus, the probability of choosing one of these 16 people in a class of 26 is 16/26 or 61.5%.
Answer:
a) θ = 
b) r = 31.27 inch
Step-by-step explanation:
(a)
area of sector: 
* r² * θ
384 = * r² * θ
384 = * (24)² * θ
θ = 384/288
θ =
(b)
384 = * r² * 
r² = 384 * 2 * 
r² = 977.848
r = √977.848
r = 31.27 inch
The number is -2 // Math [n is equivalent to number]: 2n -10 = 7n
2n = 7n + 10
-5n = 10
-n = 2
n = -2
