Answer:
See below.
Step-by-step explanation:
2b + 8 − 5b + 3 = −13 + 8b − 5
Reorder like terms.
2b-5b+8+3=8b-13-5
Combine those like terms. Then solve.
-3b+11=8b-18
-11 -11
-3b=8b-29
-8b -8b
-11b=-29
/-11 /-11
b=2.64

Answer:
Marry's seat is
units far from Betty's seat
Step-by-step explanation:
We are given that Class of Math is mapped on a coordinate grid and center point of the hall is at origin.
Coordinates of Mary's seat are (2,2) and Coordinates of Betty's seat are (6,7). We have to find how far is Mary's seat to Betty's seat. In order words, we have to find the distance between Marry's seat and Betty's seat.
Remember that whenever the coordinates of two points are given, the distance between them is calculated using the distance formula. The distance between two points
and
is given by distance formula as:
![d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E%7B2%7D%2B%28y_%7B2%7D-y_%7B1%7D%29%5E%7B2%7D%7D)
Here, the points with subscript 1 are initial points (2,2) and the point with subscript 2 are final points (6,7). Using these values in the formula, we get:
![d=\sqrt{(6-2)^{2}+(7-2)^{2}} \\\\ d=\sqrt{16+25}\\\\ d=\sqrt{41}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%286-2%29%5E%7B2%7D%2B%287-2%29%5E%7B2%7D%7D%20%5C%5C%5C%5C%20d%3D%5Csqrt%7B16%2B25%7D%5C%5C%5C%5C%20d%3D%5Csqrt%7B41%7D)
This means, Marry's seats is
units far from Betty's seat
Given that a movie producer conducted a survey after a preview screening of her new
movie to find out how the film would be received by viewers from
different age groups.
Given the table that shows the numbers of viewers in
different age groups who rated the film excellent, good, average, and
poor.
Viewer's Age Group Excellent Good Average Poor Marginal Total
16–25 52 42 12 7 113
26–35 33 50 5 9 97
36–45 58 12 28 34 132
46–55 25 17 22 12 76
56+ 12 5 3 8 28
Marginal Total 180 126 70 70 446
<span>The number of viewers from the 46 - 55 age group who rated the film excellent is 25.
Therefore, the percentage of the total survey group who </span><span>rated the film excellent and also was from the 46-55 age group</span> = 25 / 446 x 100% = 5.61%
