I’m pretty sure that I’m pretty sure that question 2 is 1 minute and 40 seconds. And for number 3 I got B. 0.25 because if you look at where the line makes a direct cross between pounds and dollars that first one is 8 pounds for 2 dollars. If you divide 8 by 2 you will get 0.25. Hope this helped :)
The number of ways that the company can choose four workers is 40920 ways.
<h3>How to calculate the number?</h3>
From the information, the building company employs 3 laborers 12 joiners 8 electrician 4 plumbers. The total number of workers will be:
= 3 + 12 + 8 + 4
= 27 workers
It should be noted that combination will be used to choose the 4 workers. This is illustrated as
Combination formula
ⁿCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
where n = 33
r = 4
ⁿCr = n! / ((n – r)! r!)
³³C₄ = 33! / (33 - 4)! 4!
= 33! / 29! 4!
= 33 × 32 × 31 × 30 / 4 × 3 × 2
= 40920 ways

-1 x + 2y = 4
<u>Explanation
</u>
The first step is to get the gradient of the line.
The two points in the line are; (4,0) and (0,2).
slope = (2 - 0)/(0 - 4)
= 2/-4
= -1/2
To get the function we use one of the point (0,2) and a general point (x,y).
1/2 = (y - 2)/(x - 0)
1/2 = (y - 2)/x
(1/2)x = y -2
x = 2y - 4
x - 2y = -4
-1 x + 2y = 4
