Answer:
480
Step-by-step explanation:
You would add 5 and 17 and that would equal 22
Now it would be 22=J-14
Then add 14 on both sides so it cancels out 22 plus 14 is 36
So J would equal 36
Answer:130 85/288 ok check my explaination if its reasonable
Step-by-step explanation:
ok youre figuring out the volume right? base times height. 5x25 1/12=125 5/12. 125 5/12x 25 inches=260 85/144 /2=130 85/288. you have to divide it by 2 because i figured it out as a rectangle.
Answer:
100.75 liters
Step-by-step explanation:
Data provided in the question:
t (min) 0 0.5 1 1.5 2 2.5 3
r (l/min) 44 40 37 34 30 27 23
Now,
left endpoint approximation
= 0.5 × ( 44 + 40 + 37 + 34 + 30 + 27 )
= 0.5 × 212
= 106
Right endpoint approximation
= 0.5 × ( 40 + 37 + 34 + 30 + 27 + 23 )
= 0.5 × 191
= 95.5
Therefore,
the average of the left- and right-endpoint approximations
= [ 106 + 95.5 ] ÷ 2
= 100.75 liters
Answer:
The number of people surveyed was 330.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the population proportion is:
The margin of error for this interval is:
The information provided is:
The critical value of <em>z</em> for 94% confidence level is, <em>z</em> = 1.88.
*Use a <em>z</em>-table.
Compute the value of <em>n</em> as follows:
![n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}](https://tex.z-dn.net/?f=n%3D%5B%5Cfrac%7Bz_%7B%5Calpha%2F2%7D%5Ctimes%20%5Csqrt%7B%5Chat%20p%281-%5Chat%20p%29%7D%7D%7BMOE%7D%5D%5E%7B2%7D)
![=[\frac{1.88\times \sqrt{0.37(1-0.37)}}{0.05}]^{2}\\\\=(18.153442)^{2}\\\\=329.5475\\\\\approx 330](https://tex.z-dn.net/?f=%3D%5B%5Cfrac%7B1.88%5Ctimes%20%5Csqrt%7B0.37%281-0.37%29%7D%7D%7B0.05%7D%5D%5E%7B2%7D%5C%5C%5C%5C%3D%2818.153442%29%5E%7B2%7D%5C%5C%5C%5C%3D329.5475%5C%5C%5C%5C%5Capprox%20330)
Thus, the number of people surveyed was 330.
