Please help me I don't understand this at all
saveliy_v [14]

Answer:

a) θ = \frac{4}{3}\pi     b) r = 31.27 inch

Step-by-step explanation:

(a)

area of sector: \frac{1}{2} * r² * θ

384 = \frac{1}{2} * r² * θ

384 = \frac{1}{2} * (24)² * θ

θ = 384/288

θ = \frac{4}{3}\pi

(b)

384 = \frac{1}{2} * r² * \frac{\pi }{4}

r² = 384 * 2 * \frac{4}{\pi }

r² = 977.848

r = √977.848

r = 31.27 inch

If there are 100 students in a Masters Degree program at OU, and there`s a 5% failure rate, how many students are left after 12
Leviafan [203]
5% fail
so 100-5=95% are left

percent means parts out of 100
95% of 100 is \frac{95}{100} times 100=95

95 students are left assuming that the 5% that fail fail within 12 months
