So... what’s the question it only shows answers huh
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: 112 square feet
Step-by-step explanation:
(4*10)+(18*4)= 40+72=112
If the larger angle is x and the smaller angle is y, y=(1/2)x+30 since it's 30 more than 1/2 of it. In addition, x+y=180 since they are supplementary. Plugging y=(1/2)x+30 into that, we get x+x/2+30=180=1.5x+30. Subtracting 30 from both sides, we get 1.5x=150. Next, we can divide both sides by 1.5 to get x=100 and y=(1/2)*100+30=50+30=80
Answer:
585 miles
Step-by-step explanation:
Basically since he drove 715 miles in 11 hours you would have to divide the 2 numbers then you get 63.
63 is the rate so then you multiply by 9 hours then that's your miles.
585 miles
