Step-by-step explanation:
65% were sold in the afternoon.
Number sold = 65% of 60
![\sf \longmapsto{= 0.65×60 = 39}](https://tex.z-dn.net/?f=%20%5Csf%20%5Clongmapsto%7B%3D%200.65%C3%9760%20%3D%2039%7D)

Answer: b. (.54, .71)
Step-by-step explanation:
Confidence interval for population proportion is given by :-
![\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%5Cpm%20z%5Csqrt%7B%5Cdfrac%7B%5Chat%7Bp%7D%281-%5Chat%7Bp%7D%29%7D%7Bn%7D%7D)
,where
= sample proportion
z= Critical z-value
n= sample size.
Let p be the proportion of people who support additional handgun control.
As per given , we have
n= 80
![\hat{p}=\dfrac{50}{80}=0.625](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cdfrac%7B50%7D%7B80%7D%3D0.625)
Critical z-value for 90% confidence interval is 1.645
Now , a 90% confidence interval for the population proportion of those who support additional handgun control will become:
![0.625\pm (1.645)\sqrt{\dfrac{0.625(1-0.625)}{80}}](https://tex.z-dn.net/?f=0.625%5Cpm%20%281.645%29%5Csqrt%7B%5Cdfrac%7B0.625%281-0.625%29%7D%7B80%7D%7D)
![=0.625\pm (1.645)\sqrt{0.0029296875}](https://tex.z-dn.net/?f=%3D0.625%5Cpm%20%281.645%29%5Csqrt%7B0.0029296875%7D)
![=0.625\pm 0.089\\\\=(0.625-0.089, 0.625+0.089)\\\\=(0.536,\ 0.714)\approx(0.54,\ 0.71)](https://tex.z-dn.net/?f=%3D0.625%5Cpm%200.089%5C%5C%5C%5C%3D%280.625-0.089%2C%200.625%2B0.089%29%5C%5C%5C%5C%3D%280.536%2C%5C%200.714%29%5Capprox%280.54%2C%5C%200.71%29)
So the correct answer is : b. (.54, .71)
Los tres puntos son (-3,0), (3,0), (0,4).
Por lo tanto, la respuesta es A, espero que esto ayude, que tenga un buen día.
3/4 hours is equal to (60 minutes divided by 4) times three. [15*3 = 45]
Macy finished in 45 minutes. Now we have to find 4/5 of 45. So (45 divided by 5) times 4. [9*4 = 36]
See the pattern? So the answer for 45 minutes divided by 4/5 is 36 minutes.
Answer:
2x-6=-16 and 3x- 10=8
Step-by-step explanation:
2x=-16+6 and 3x=8+10
2x=-10 and 3x=18
2x/2=10/2 and 3x/3=18/3
x=5 and X=6
