1. A spinner is divided into 4 uneven sections and labelled 1, 2, 3, 4. It is 4 times more likely to land on a 3 than any other numbers. [3/2]
a) Create a table and a graph representing the probability distribution of the spinner.
b) Find the expected value of the spinner.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20
