In order to do this you must use what is called a discipline to get your answer
Answer:
I took the test!!
Step-by-step explanation:
Pit this in your calculator exactly like this 4,000(1.05)^5 and you get the answer 5,105.12625. So round your answer to the nearest dollar, which is 5,105.
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.
Answer:
A)25
B) 14
Step-by-step explanation:
A) a/5 + 3 = 8
a/5 = 8 - 3
a = 5 x 5
a = 25
B) 3b/7 -1 =5
3b/7 = 5+1
3b = 6 x 7
b = 42/3
b = 14
1. Linear
2. Quadratic
