Because in our sample of 40 days, the Hob has had fewer than 20 customers 25/40=5/8 of the time, the best estimate of the probability that there will be fewer than 20 customers the next day is 5/8. If the Hob had fewer than 20 customers 5/8 of the days, then it had at least 20 customers 3/8 of the days, so the best estimate of the probability that it has at least 20 customers the next day is 3/8.
If B is a complement of A this means that the sum of the measures of A and B is 90 degrees.
mA + mB = 90
mB =90 - mA
mB = 90 - 40 = 50
Thus, the measure of angle B is 50 degrees.
If C is a supplement of B then, the sum of the measures of B and C is 180 degrees.
mC + mB = 180
mC = 180 - mB
mC = 180 - 50 = 130
Therefore, the measure of angle C is 130 degrees.
Answer:
y = 496
Step-by-step explanation:
62 - 1/8y = 0
8 (62 - 1/8y ) = 8×0
496 - y = 0
496 = y
y = 496
