What is the slope of the line shown in the graph below?
Answers
Answer:
-2/3
Step-by-step explanation:
Since slope is just rise over run, find the y intercept and see how far it is from the x axis. If it goes down and is above \the x axis, then it is negative and if it is under the x axis, then it is positive. Then count how far the x intercept is. Same concept as the y intercept. Then, you put it as a fraction (y goes on top of x) and simplify to get your slope.

Every triangle has a total of 180 (when you add all three angles together), and the same would be for a straight angle, or two angles formed by am angle bisector (DC). 180-33=147, so the top part of C would be 147, which isn't necessarily needed, but that'd be how to solve that. A+B+C=180. A+2x+C=180. A would be 33 because AB and DC (segments) are parallel, and the segment bisector AE is a straight line, so 33+2x+C=180. 180-33=147/2=73.5, if I did that correctly.

The number of boys is 3/5 of the number of girls. If there are 120 children all together, how many boys are there? PLEASE HELP ME!!!!!!!!
Answers
Answer:
72 boys
Step-by-step explanation:
120 * .60. That's how you solve it! Hope it helps!
Further explanation:
To get .60, you divide 3 by 5 which is .60
Then you multiply 120 times .60 and you'll get 72 which is 72 boys
Bonus: 120 - 72 = 48 girls!
Answer:
There are 45 boys.
Step-by-step explanation:
The best way to easily solvethis is by making equations, see below.
[tex]let \: b \: represent \: number \: of \: boys \\ let \: g \: represent \: number \: of \: girls[/tex]
[tex]b + g = 120 \\ b = \frac{3}{5} g[/tex]
Now we can subtract the secons equation from the first.
[tex]g = 120 - \frac{3}{5} g[/tex]
I'm also goong to multiply the equatipn by 5 to remove the fraction.
[tex]5g = - 3g + 600[/tex]
Now simplify
[tex]8g = 600 \\ g = 75[/tex]
Now we found out there are 75 girls. Now we insert this into our second equation to find how many boys there are.
[tex]b + 75 = 120 \\ b = 45[/tex]
Now we know there are 45 boys.
A guidance counselor wants to determine if there is a relationship between a student’s number of absences, x, and their grade point average (GPA), y. He collects data for 15 randomly selected students and determines the value for r2 was 31%.
Which of the following gives the best interpretation of this value?
31% of the variation in the number of absences is accounted for by the linear relationship with GPA.
69% of the variation in the number of absences is accounted for by the linear relationship with GPA.
31% of the variation in the GPA is accounted for by the linear relationship with number of absences.
56% of the variation in the GPA is accounted for by the linear relationship with number of absences.
Answers
Answer:
C: 31% of the variation in the GPA is accounted for by the linear relationship with number of absences.
Step-by-step explanation:
right on edge
The correct interpretation of the value of r² in this context is 31% of the variation in the GPA is accounted for by the linear relationship with the number of absences.
The interpretation of the value of r² in the context of the relationship between a student's number of absences (x) and their grade point average (GPA) (y).
First, what is r²? The coefficient of determination, denoted as r², is a statistical measure that represents the proportion of the variance (variation) in the dependent variable (GPA) .
That can be explained or predicted by the independent variable (number of absences) in a linear regression model.
Here, the value of r² is 31%. This means that 31% of the total variability in the GPA scores of the 15 randomly selected students can be explained by the linear relationship with the number of absences.
31% of the differences in GPAs among the students can be attributed to the differences in their number of absences.
The remaining percentage (100% - 31% = 69%) represents the unexplained or residual variation in the GPA scores.
This unexplained variation could be due to other factors not considered in the linear relationship, such as individual study habits, natural academic ability,
or other variables that were not part of the data analysis.
The interpretation is that 31% of the variation in the GPA scores can be accounted for by the linear relationship with the number of absences, while 69% of the variation remains unexplained by this relationship.

A line drawn from one side of a circular plate to the other, through the center of the plate, measures 25 centimeters.
What is the approximate area of the plate to the nearest square centimeter?
39 centimeters²
79 centimeters²
156 centimeters²
491 centimeters²
Answers
Answer:
39 centimeters
Step-by-step explanation:
to find the area of a circle you first find the radius which is the disctance from the edge of the plate to the center. you then multiply it by pi to find the total area.
The required area of the given plate with a diameter of 25 centimeters is 491 centimeters². Option B is correct.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
here,
A line drawn from one side of a circular plate to the other, through the center of the plate, measures 25 centimeters.
So, the Diameter of the plate = 25 centimeters,
The area of the plate is given as,
Area of plate = π × [diameter/2]²
= 3.14 × [25/2]
= 491 centimeters²
Thus, the required area of the given plate is 491 centimeters². Option B is correct.

A linear function models the height of a burning candle. Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning. The model for Candle B is h=210−5t, where h is the height in millimeters and t is the time in hours. What are the initial values for each candle? What do the initial values for each candle tell you?
Answers
Given:
Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning.
The model for Candle B is
[tex]h=210-5t[/tex]
where, h is the height in millimeters and t is the time in hours.
To find:
The initial values for each candle and its interpretation.
Solution:
Candle A comes out of the mold at 211 mm, and is expected to be at 187 mm after 8 hours of burning.
So, initial value of candle A = 211 mm
The model for Candle B is
[tex]h=210-5t[/tex]
Putting t=0, we get
[tex]h=210-5(0)[/tex]
[tex]h=210-0[/tex]
[tex]h=210[/tex]
So, initial value of candle B = 210 mm
Initial values for each candle tell you about the height of the candles before they start burning.
Initial value of candle A is greater than B, so the height of candle A is greater than B before they start burning.
Therefore, the initial value of candle A is 211 mm and initial value of candle B is 210 mm.
