Answer:
C. 30
90/30=3
3x10= 30
SECOND PART
the second year would only have 25 acts
100/4=25
Uhhh I think you have to add 19 and 14 which shall give you the answer to a1 so it should be 33 but then I think you divide 33 and 96 or you will multiply 33 and 96
Sector Area = (central angle / 360) * PI * radius^2
Sector Area = 300 / 360 * PI * 8^2
Sector Area = (5/6) * 64 * PI
Sector Area = 53.3 * PI

The hand turn 1 quarter of a circle (1/4). it turned 90 degrees
Let x be the number of adults (under 50 years old) after a 12-hour fast where X ~ N(85,25)
The problem is missing some parts but here are the answers:
(a) x is more than 60
z(60) = (60-85)/25 = -1
P(x > 60) = P(z > -1) = 0.158655
(b) x is less than 110
z(110) = (110-85)/25 = 1
P(x < 110) = P(z < 1) = 0.841345
