Jeremy is a snowboarder. One of his best tricks is catching big air, jumping off the ramp while holding on to the snowboard. Jer
emy did this trick 20 times, the heights (in meters) of which were {18, 23, 15, 16, 15, 17, 22, 16, 19, 11, 24, 14, 12, 16, 20, 18, 14, 13, 21, 11}. What is the median value of Jeremy’s big air trick?
Write down all of the #'s on a piece of paper 18,23,15,16,15,17,22,16,19,11,24,14,12,16,20,18,14,13,21,11
Put them in order 11,11,12,13,1414,15,15,16,16,16,17,18,18,19,20,21,22 Cross em off on eah side until you reach the middle 16, 16 Since there's 2 instead of 1 middle # Add up the 2 (16+16 = 32) Then divide by 2 (32/2 = 16)
We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period
.
To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:
Commutative property of multiplication states that we can multiply numbers in any order.
Upon switching the order while multiplying, we will get:
Therefore, our required equivalent expressions would be and .
The reciprocal is the fraction flipped. To make sure it is a reciprocal though, multiply the original and the reciprocal. If it is the correct reciprocal, you will get 1 as your answer.
