Answer:
$21.25
Step-by-step explanation:
1. Convert the 15% to a decimal by dividing by 100. 15 ÷ 100 = 0.15
2. Multiply the $25 by the decimal of 15%. 25 × 0.15 = 3.75
3. Subtract your previous answer (3.75) from the original price of the game station. 25 - 3.75 = 21.75
4. Therefore the price of the game station after the discount is $21.75.
Looks like the PMF is supposed to be

which is kinda weird, but it's not entirely clear what you meant...
Anyway, assuming the PMF above, for this to be a valid PMF, we need the probabilities of all events to sum to 1:

Next,





If

, then

, where we take the positive root because we know

can only take on positive values, namely 1, 2, and 5. Correspondingly, we know that

can take on the values

,

, and

. At these values of

, we would have the same probability as we did for the respective value of

. That is,

Part (5) is incomplete, so I'll stop here.
Answer:
88 inches ^2
Step-by-step explanation:
Well find the side of a triangle first.
4*9=26
26/2=18
There are 4 identical triangles
18*4= 72
Now the bottom square
4*4=16
16+72= 88
88 inches ^2
