Answer:
Step-by-step explanation:
<span> 3x^2 − 6x = 24
</span>3x^2 − 6x - 24 = 0
3(x^2 - 2x - 8) = 0
3(x - 4)(x + 2) = 0
x - 4 = 0; x = 4
x + 2 =0; x = -2
answer
<span>C) x = −2, x = 4</span>
Answer: b(-2, 2) c(4,2) d (-6,7)
Step-by-step explanation:
The formula for reflecting over x axis is (x,y) - > (x,-y)
the current points are
-2,-2
4, -2
-6, -7
which turn into -2, 2
4, 2
-6,7
The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
