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:
a=-16, b=11, c=23
Step-by-step explanation:
The function whose table is drawn is
To find the value of a, we substitute x=-5.
To find the value of b, we substitute x=4.
To find the value of c, we substitute x=8,
The area is 12.57
Formula: PieR^2
Answer:
Step-by-step explanation:
The driveway has the shape of a cuboid. The formula for determining the volume if a cuboid is expressed as
Volume = L × W × H
Where
H represents the thickness of the gravel to be added to the driveway.
W represents the width of the driveway.
L represents the length of the driveway.
From the information given,
L = 15 yards
W = 3 yards
H = 6 inches.
36 inches = 1 yard
6 inches = 6/36 = 0.167 yard
Therefore, the volume of gravel required would be
V = 15 × 3 × 0.167 = 7.515 cubic yards
I believe the correct answer is true. <span>When solving a system of linear equations, try to algebraically form one equation that has only one variable. In this way, you can solve the value of that variable and eventually solve the other variables. Hope this answers the question. Have a nice day.</span>
