Question

a. what number represents the change in weight for each day of hibernation?
b. what number represents the change in weight in ounces for the hedgehog in 115 days of hibernation?

1. a basketball team played six games. in those games, the team won by 7 points, lost by 20, won by 8, won by 11, lost by 3, and won by 9. which was the mean amount by which the team won or lost over the six games?

a -3 points
b 2 points
c 3 points
d 6 points

1. in digging a hole, the construction crew records the location of the bottom relative to ground level. in the first 3 hours, the crew digs at a rate of -2.75

part a
how many feet would the crew record after 3 hours? write an expression representing this situation. 7.ns0.2.2, 7.ns0.2.3
part b
in the next 3 hours, of -2.5 feet each hour, crew slowed to a rate number would they the 8 hours? write

Explanation:

19.

Step1: Define wins and losses as signed - numbers

Wins are positive and losses are negative. So the values are \(7, - 20,8,11,-3,9\).

Step2: Calculate the sum of the values

\[7+( - 20)+8 + 11+( - 3)+9=(7 + 8+11 + 9)+(-20-3)=35 - 23 = 12\]

Step3: Calculate the mean

The mean is the sum divided by the number of games. There are \(n = 6\) games. Mean\(=\frac{12}{6}=2\)

Step1: Identify the rate and time

The rate of digging is \(r=-2.75\) feet per hour and the time \(t = 3\) hours.

Step2: Use the formula \(d=r\times t\)

The distance \(d\) (depth in this case) is given by the product of the rate and time. The expression is \((-2.75)\times3\)
\[(-2.75)\times3=-8.25\]

Answer:

B. 2 points
