Answer:
B) y = x + 2
Step-by-step explanation:
Coordinates of point C =
Coordinates of point D=
To find the equation of segment CD
Formula : 
Substitute the values in the formula :

y-12=x-6
y=x+6
When two lines are perpendicular to each other the product of their slopes is -1
Let the slope of perpendicular line be x
So, -1 \times x = -1
So, x =1
General equation : y = mx+c
So, Option B has slope = 1
So,the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8) is y = x + 2
Answer:
D)We are 95% confident that the proportion of adults (ages 17‐26) who attended college during the past 4 years and say that alcohol and drug use at their school is a big problem is between 53% and 59%.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% confidence interval is (0.53, 0.59).
This means that we are 95% sure that the true proportion for the population of adults who attended college who say that alcohol is a big problem is between 0.53 and 0.59. This means that the answer is given by option D.
Question asks to estimate.
So do 300/40 to get 7.5
The answer is 41 because all of the them are in the 7 times table .so I deducted 2 from each one of them and 41 was not part
<span>x^2 + 8x = -3
</span><span>x^2 + 8x + 16 = -3 + 16
using a^2 + 2 a b + b^2 = (a+b)^2
</span><span>
</span>x^2 + 8x + 16 = 13
<span>(x +4)^2 = 13
answer : 16 is the number </span><span>you must add to complete the square</span>
