Numbers 100 to 125 are written on separate slips (one number on one slip), kept in a box and mixed well. One slip is chosen from

Wittaler [7]

Step-by-step explanation:

The numbers are given as;

100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125

What is the probability of getting;

a) A number 108?

Probability = Number of favorable outcomes / Total number of outcomes

Number of favourable outcome = 1

Total number of outcomes = 26

Probability = 1 / 26

B) a number less than 107

Probability = Number of favorable outcomes / Total number of outcomes

Number of favourable outcome = 100, 101, 102, 103, 104, 105, 106 = 7

Total number of outcomes = 26

Probability = 7 / 26

c) A number greater than 120

Probability = Number of favorable outcomes / Total number of outcomes

Number of favourable outcome = 121, 122, 123, 124, 125 = 5

Total number of outcomes = 26

Probability = 5 / 26

Gary and Richard are practicing tying knots. Richard already has 3 knots tied when Gary starts.

Artyom0805 [142]

In graphs of linear relationships, you can always determine a proportional linear relationship by observing where the line crosses the y axis. If the line crosses through the origin, then the relationship is proportional. This means that the independent data(in this case time) can be multiplied by a constant factor to always get it's related dependent piece of data.

From the graph you might notice some data points for Gary: At 2mins he completes 1.5 knots or the ordered pair (2, 1.5). We see another data point at 4mins he completes 3 knots or the ordered pair (4,3). How about the ordered pair (6, 4.5)? Notice that if I multiply the "x" coordinate of all these ordered pairs by 0.75, I get the "y" coordinate. Or maybe another way to look at it, the "y" coordinate of each point on the line divided its corresponding "x" coordinate will always produce the same number, 0.75. This number, 0.75, is called the constant of proportionality.

So, the answer to this problem is choice "D"

Summary: To identify proportional linear relationship from a graph, look for the line that goes through the origin. To find the constant of proportionality, determine the coordinates of a convenient point on the line and divide the y coordinate by the x .
