Answer:True
Step-by-step explanation:
Question 1:
Sub the coordinates in for x and y
Y=-6x + b
1=-6(-4) +b
1= 24 +b
-23=b
Final answer: Y=-6x -23
Repeat for question 2
Question 3:
Slope = y2-y1/x2-x1
8-11/2- -4
-3/6= -0.5
Slope is -0.5
Sub x and y into equation
Y=-0.5x +b
11=-0.5(-4) +b
11=2+b
9=b
Y=-0.5x +9
Repeat for question 4
Answer:
x = 14
Step-by-step explanation:
This problem requires and understanding about interior sum of angles.
This is an irregular hexagon. so Total angle sum = 180*(6 - 2) = 720 degrees.
...
80 + 56 + 61 + 43 + 92 + 2x = 360
332 + 2x = 360
2x = 360 - 332
2x = 28
x = 14
or... 6*180 - (332 + 2x) = 720
748 - 2x = 720... x= 14
I think it’s the first one.
Hope this helps :)
Answer:
And replacing the info from the problem we have:
So then the best estimator for the true proportion p is given by or equivalent to 3.2 %
Step-by-step explanation:
We want to find a confidence interval for a proportion p who represent the parameter of interest.
The confidence interval would be given by this formula:
For this case the 90% confidence interval is given by (1.8%=0.018, 4.6%=0.046) after apply the last formula
Since the confidence interval is symmetrical we can estimate the point estimator of the true percentage with this formula:
And replacing the info from the problem we have:
So then the best estimator for the true proportion p is given by or equivalent to 3.2 %
