If your decimal is 1/2 or more u round up if it is less than half u round down
Answer:
a)y=3/2x+6 b) y= -4/3x-2
Step-by-step explanation:
a)using the points given (-2,2) and (0,6)
we use rise over run formula and get 3/2
and we get y intercept by looking at when the line touches the y line in this case 6
using y=mx+b formula when m is slope and b is y interecpt we plug the numbers in
so we get y=3/2x+6
b) For this we use the points given which are (-3,2) and (0,2)
we use the rise over run formula and get 4/3 but since the line is going down it means the slope is negative so we get -4/3
and the y intercept we get by looking at when it touches the y line in this case it touches at -2
so using the same formula as the first question
but since the y interecpt is negative we change the plus sign for a minus
we get y=-4/3x-2
Answer:
455.
Step-by-step explanation:
Yes. You require the number of combinations of 3 from 15.
15C3
The formula for this is 15! / 12! 3! or you can do itr as follows
15C3 = 15*14*13/3*2*1
= 5*7*13
= 35*13
= 455.
Your proportion would be 13/3 =x/4,000.
