Answer:
(0.4543 ; 0.5057)
Step-by-step explanation:
This is a confidence interval for one sample proportion :
Phat , = 0.48
Sample size = 1450
1 - phat = 1 - 0.48 = 0.52
Zcritical = 95% ; Zcritical at 95% = 1.96
Using the relation :
Phat ± Zcritical *√[phat(1-phat) / n]
√[phat(1-phat) / n] = √(0.48*0.52) /1450) = 0.0131201
Lower boundary :
0.48 - (1.96 * 0.0131201) = 0.4543
Upper boundary :
0.48 + (1.96 * 0.0131201) = 0.5057
(0.4543 ; 0.5057)
14.4/4 is 3.6. Therefore the answer is 3.6.
Answer:
they are adding by 7 because 6 +7=13
Answer:
Perimeter is (width×height) but in this case it would be base×width & height...
First find the with of the triangle,by measureing the points with the base.
Second to find the base simply look equilateral and the half circle. and see how the lines in between it and the triangle collide. and count the spaces to find the base.
Third measure the height with the best estimate.
And finally, multiply by (h×w) and divide by the base.
After following these steps the answer I have come to is: 45
Step-by-step explanation:
I'm sorry if this is wrong I tried my best ❤️Good luck! and have a great day or night!
The given inequality is

First we need to remove the absolute sign , and when we do so , we will get a compound inequality, that is

To solve for x, first we need to get rid of 10. and for that, we have to do subtraction

Now we need to get rid of 9, and for that, we do division

So the required solution is
