Answer:
Step-by-step explanation:
Cindy is correcy because on "Step 1:" the multiplication was correctly distributed over the subtraction in paranthesis 5(x-2) = 5*x- 5*2 = 5x-10.
Henry was wrrong because he distributed 5 only over x and not over -2 as well 5(x-2) ≠ 5*x-2

- Sum of Angles: 180(n - 2)
Step-by-step explanation:
<u>Step 1: Define</u>
Number of sides <em>n</em> = 10
<u>Step 2: Find</u>
- Substitute: 180(10 - 2)
- Subtract: 180(8)
- Multiply: 1440°
<u>Step 3: Find 1 angle</u>
<em>We have 10 sides.</em>
- Divide: 1440/10 = 144
Answer:
P(number greater than 3) = 
Step-by-step explanation:
The Probability of getting a number greater than 3 means the possibility of getting 4 or 5 or 6
That is
P(number greater than 3) = P(getting 4) + P(getting 5) + P(getting 6)
On substituting the values from the table ,
we get
P(number greater than 3) = 
P(number greater than 3) = 
Thus if the number cube is tossed once, P(number greater than 3) is
