Before we begin, let's make the fractions and percents a decimal. 100% as a decimal is 1, 45/40 as a decimal is 1.125, and 2/3 as a decimal is 0.666. Now, we have 1, 1.125, 0.4, and 0.666. You asked to order them from greatest to least. Here is the order it should be in. 45/40, 100%, 2/3, 0.4

Can someone please write an equation to model this scenario which relates to the first two questions. I need it ASAP!
Vika [28.1K]

Answer:

y = 50x + 200

Step-by-step explanation:

the 200 is the y intercept because it is where his pay starts, so even if Matt doesnt make any sales he will still get 200 that week

the slope (50) is determined because that is what will change

if he makes 2 sales he will make 100 + 200 that week, and if he makes 4 sales he will make 200 + 200 that week and so on

Each of 5 boys randomly chooses a watch from 12 different styles. What is the probability that at least 2 boys choose the same t
aleksley [76]

Answer:

Ok. So we have 12 different styles of watches to choose from, so that means that the total number of combinations of styles for 5 boys is 12*12*12*12*12, since each boy has his pick of 12 options.

The way to answer this question is by way of the complementary rule: We want the number of ways that the boys can all have different styles. So the first boy to pick has 12 options available to him, the second boy has 11 options available to him, the 3rd boy has 10 options available to him, so on and so forth.

So the probability that the boys all have different watches is (12*11*10*9*8)/12^5= .3819.

To find the probability that at least two boys have the same style would just be 1 -.3819 = 6181
