Answer:
27.9135
Step-by-step explanation:
2 minutes 30 seconds - 3 minutes
A) 19m because 3 times 6 is 18 then you add m, which would be 19m
You first need to determine the total number of possibilities with a 4-color
spinner and a 6-sided die.
The way to do this is using the counting principle.
You can match each color with each number so you can get 4 * 6 different combinations, or 24.
There will only be 1 combination of P(5,Blue).
So P(5,Blue) = 1/24
Answer:
y=3x.........1
y=x^2-10.......2
substituting value of eq 1 to 2
3x=x^2-10
x^2-10-3x=0
x^2-3x-10=0
x^2-5x+2x-10=0
X(x-5)+2(x-5)=0
(x-5)(X+2)=0
then
X=5 or X=-2
again
y=??
when X=5
y=3×5=15
when X=-2
y=-6
