Answer:
1. predicted attendance: 141.35
2. residual: 18.65
Step-by-step explanation:
1. Predicted attendance is ...
y = -5.9·5 +170.85 = 141.35
__
2. As the problem statement tells you, ...
actual value - predicted value = residual
160 - 141.35 = 18.65 . . . the residual
In the deck of cards, there is a total of 52 cards which
comprises of: kings, queens, jacks, 10, 9, 8, 7, 6, 5, 4, 3, 2, and aces.
In the problem, we were asked the probability of less than
5, so it would be Ace, 2, 3, and 4. 5 is not included since the problem didn’t
ask less than or equal to.
So 4 cards and we have 4 suits in the deck. So 4 x 4 = 16.
16/ 52 = .31 is the probability.
Answer:
The correct answer is D) 243
Step-by-step explanation:
In step two. If we look on the left side of the equation in the first step, it reads 4(2x-4). When a number is multiplying an expression in brackets, we have to multiply every term in the brackets by the number in front of the brackets. In this case, it would be 4*2x + 4*(-4), which is 8x - 16. So the correct option would be the second (8x-16=16+2x) (the right side of the eqtn was 8+2x+8 and if we combine like terms we get 16+2x)
