Answer:
Equation: y - 3x/4 + 4
Step-by-step explanation:
using the formula:
- y = mx + b ................where m is slope and y-intercept is b
So using the formula:
Answer:
No the evidence is not sufficient
Step-by-step explanation:
From the question we are told that
The sample size is ![n = 900](https://tex.z-dn.net/?f=n%20%20%3D%20%20900)
The sample proportion is ![\r p = 0.75](https://tex.z-dn.net/?f=%5Cr%20p%20%20%3D%200.75)
The population proportion is ![p = 0.72](https://tex.z-dn.net/?f=p%20%20%3D%200.72)
The Null hypothesis is
![H_o : p = 0.72](https://tex.z-dn.net/?f=H_o%20%20%3A%20p%20%3D%20%200.72)
The Alternative hypothesis is
The level of significance is given as ![\alpha = 0.05](https://tex.z-dn.net/?f=%5Calpha%20%20%3D%200.05)
The critical value for the level of significance is ![t_{\alpha } = 1.645](https://tex.z-dn.net/?f=t_%7B%5Calpha%20%7D%20%20%3D%20%201.645)
Now the test statistic is mathematically evaluated as
![t = \frac{\r p - p }{ \sqrt{\frac{p(1-p)}{\sqrt{n} } } }](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7B%5Cr%20p%20-%20%20p%20%7D%7B%20%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7B%5Csqrt%7Bn%7D%20%7D%20%7D%20%7D)
substituting values
![t = \frac{ 0.75 - 0.72 }{ \sqrt{\frac{0.72 (1-0.72)}{\sqrt{900} } } }](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7B%200.75%20-%20%200.72%20%7D%7B%20%5Csqrt%7B%5Cfrac%7B0.72%20%281-0.72%29%7D%7B%5Csqrt%7B900%7D%20%7D%20%7D%20%7D)
![t = 0.366](https://tex.z-dn.net/?f=t%20%3D%20%200.366)
Since the critical value is greater than the test statistics then the Null hypothesis is rejected which there is no sufficient evidence to support the claim
Answer:
6x = 54; x = 9 times older

Answer:
B. You have to pay interest on charge cards but not on credit cards.
Step-by-step explanation:
Answer:
3^3 = 27
27 * 3.14 = 84.78
84.78 * 4/3 = 113.04 is your answer.
Formula of volume of sphere is:
4/3 x π(3.14 or 22/7 whatever they tell you to use for pi) x r^3(your radius being cubed)
You get your radius by finding out what is half of your diameter or your given radius.
