The point Estimate is 0.645 , the confidence interval is (0.525 ,0.764).
<h3>What is Point Estimate ?</h3>
The point estimate is the proportion of success in the sample.
From the data given
p = 40/62
p = 0.645
The point Estimate is 0.645
(b) Confidence interval for true proportion is
For 95 % Z = 1.96
p =0.645
1-p = 0.355
putting the values
(0.525 , 0.764)
Lower Limit = 0.525
Upper Limit = 0.764

Answer:
28
Step-by-step explanation:
all adds up to 180 degrees
so 4x+3+2x+9=180
=6x+12=180
6x=168
x=28
Answer: You will have points plotted at +3 on the y axis, and +3 on the x axis.
The attachment shows what your graph should look like.
Step-by-step explanation:
The intercept is where the graphed line crosses an axis.
To find the y-intercept, substitute 0 for x and solve for y:
0 + y = 3. Subtracting 0, you have y = 3
So you can plot a point at +3 on the y axis.
To find the x- intercept, substitute 0 for y, and solve for x
x + 0 = 3 Again, subtracting 0, x = 3
So plot a point on the x-axis at +3
Use the line tool to connect the two points.
Answer:
5n^2 - 3n - 8
Step-by-step explanation:
4n.5n - 4n.8 + 4.5n - 4.8
= 20n^2 - 32n + 20n - 32
= 20n^2 - 12n - 32
= 4 ( 5n^2 - 3n - 8 )
= 5n^2 - 3n - 8 [ answer ]
