Answer: The width is the square root of 40 or 6.32
Step-by-step explanation:
9^2 + b^2 = 11^2 where b squared is the width
81 + b^2 = 121
-81 -81
b^2 = 40
b= 6.32
Answer:
Students deliver catalogues and leaflets to houses.
One day, they have to deliver 480 catalogues and 1520 leaflets.
Each student can deliver either 15 catalogues or 80 leaflets in 1 hour. Each student can only work for 8 hours. All students hired are paid £50.40 per day, even if they don't work a full day.
If the minimum number of students are hired, how much will the wage bill be?
X*.04 = 56
x = 56/.04
x = 1400
(* means "times")
Answer:The probability of the complement of an event is one minus the probability of the event. Since the sum of probabilities of all possible events equals 1, the probability that event A will not occur is equal to 1 minus the probability that event A will occur.
Step-by-step explanation:Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.
