Answer:

Step-by-step explanation:
InO0, mCA=150andAB=CD
What is mBD?
Answer: I’m pretty sure that BD should also be 150
Step-by-step explanation:
The measure of angle O is 75 because the angle is always half of the arc, so knowing that, and also cd and abs are congruent, the other side of o is probably the same as the other, so it’d be 75, multiply by 2 and itll be 150.
HELP ME PLS IF ITS POSSIBLE PLS ANSWER ALL THESE QUESTIONS!! <3
Answer:
1.) the range is 42
2.) mean: 69.4, median:63, mode:none
3.) none since they are numbers that can be high but not low.
4.)The outlier is a greater number like the mean is 69 and the median is 63 which is halfway between 63 and 64 it will affect more the mean than the median since it doesn't matter the actual value of the outlier. it just depends on what the outlier is.
5.) the measure of central tendency best describes the set data with the outlier to which there is no outlier.
Step-by-step explanation:
Make a circle graph for each set of data.

Question:
Find the scale factor of trapezoid [tex]\mathrm{Q}\mathrm{R}\mathrm{S}\mathrm{T}[/tex] if it is dilated to [tex]\mathrm{Q}^{'} \mathrm{R}^{'} \mathrm{S}^{'} \mathrm{T}^{'}[/tex].
Type your result in the empty box provided below.
Answer:
The scale factor is 2
Step-by-step explanation:
Given
See attachment for plots
Required
Determine the scale factor
Using QR and Q'R' as points of reference.
From the attached plot, we have:
[tex]QR = 4\ units[/tex]
[tex]Q'R' = 8\ units[/tex]
The scale factor (k) from [tex]\mathrm{Q}\mathrm{R}\mathrm{S}\mathrm{T}[/tex] to [tex]\mathrm{Q}^{'} \mathrm{R}^{'} \mathrm{S}^{'} \mathrm{T}^{'}[/tex]. is:
[tex]k = \frac{Q'R'}{QR}[/tex]
[tex]k = \frac{8\ units}{4\ units}[/tex]
[tex]k =2[/tex]

16a - 3y = 12
What are the solutions to this system of equations?
Answer:
( 3 , 0 ) ( 0 , − 6)a = 12 + 3y/ 16Step-by-step explanation:
Add 3 to both sides
16a-3y+3y=12+3y
Simplify
16a=12+3y
Divide both sides by 16
16a/16 = 12/16 + 3y/ 16
a= 12+ 3y/16
