ABC measures 140° and is bisected
by BD. What is mDBC= ?
Answers
Answer:
angle abc =140°
and bd bisected by bd so, bd divede angle abc.
angle dbc= angle abc / 2
angle dbc=140°/2
angle dbc=70°
The measure of angle DBC from the given figure is 70°.
The measure of angle ABC is 140°.
What is an angle bisector?The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.
Angle bisector BD is bisecting angle ABC equally, which is
∠ABC=∠ABD+∠DBC
⇒ 140°=∠DBC+∠DBC
⇒ 2∠DBC=140°
⇒ ∠DBC=70°
Therefore, the measure of angle DBC from the given figure is 70°.

A business school is conducting a study to investigate whether a students’ scores on a placement test can be used to predict students’ starting salaries. Based on a random sample of 200 graduates of the business school, a 98 percent confidence interval for the slope of the linear regression line relating placement scores and starting salary is calculated to be (315,336). Assume the conditions for inference are met.
Which of the following is a correct interpretation of the confidence interval?
a. There is a 98 percent probability that the slope of the population regression line is between $315 per point and $336 per point.
b. Ninety-eight percent of the time, a 10-point increase in placement score will result in an average increase between $3,150 and $3,360 in starting salary.
c. We are 98 percent confident that a 10-point increase in placement score will result in a predicted increase in starting salary of between $3,150 and $3,360.
d. We are 98 percent confident that predicted starting salaries will be between $315,000 and $336,000.
e. We are 98 percent confident that the regression equation can be used to make accurate predictions for placement scores between 315 and 336.

1. Rearrange terms.
12x-15=6-3x
12x-15=-3x+6
2. Add 15 to both sides.
12−15=−3+6
12−15+15=−3+6+15
3. Simplify
If you add the numbers you will get:
12x=-3x+21
4. Add 3x to both sides of the equation.
12x=-3x+21
12x+3x=-3x+21+3x
5. Simplify
If you combine the like terms you will get,
15x=21
6. Divide both sides of the equation by the same term.
15x=21
[tex]\frac{15x}{15}[/tex] = [tex]\frac{21}{15}[/tex]
7. Simplify
If you cancel terms that are in both of the numerator and denominator, then divide the numbers you will get:
x= [tex]\frac{7}{5}[/tex]

AB = ?
Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)
AB² = 7² + 6² - 2(7)(6)*Cos(59)
AB² = 85 - 43.26

Polina’s math scores are shown in the table. Polina’s Math Scores Math Scores 72 65 75 88 90 What is the mean absolute deviation of her math scores? 5.4 6.4 7.8 8.8
Answers
The mean absolute deviation of Polina's math scores is 8.8.
The answer is D) 8.8.
What is the mean absolute deviation?
The mean absolute deviation (MAD) is a measure of variability that quantifies the average difference between the observations in a dataset and the dataset's mean. It is calculated by finding the average of the absolute deviations of the data points from their mean.
To find the mean absolute deviation (MAD) of Polina's math scores, we first need to find the mean of the scores:
Mean = (72 + 65 + 75 + 88 + 90)/5
Mean = 78
Next, we find the absolute deviation of each score by finding the difference between each score and the mean, taking the absolute value of the difference, and then adding up the absolute differences:
|72 - 78| = 6
|65 - 78| = 13
|75 - 78| = 3
|88 - 78| = 10
|90 - 78| = 12
Sum of absolute deviations = 6 + 13 + 3 + 10 + 12
Sum of absolute deviations = 44
Finally, we find the MAD by dividing the sum of the absolute deviations by the number of scores:
MAD = 44/5
MAD = 8.8
Therefore, the mean absolute deviation of Polina's math scores is 8.8.
The answer is D) 8.8.
