Answer:
$10
Step-by-step explanation:
The question made is How much did I have? This question is about the amount of money that you had before receiving the money from your mom, dad and aunt and uncle. This means that the answer is the $3 you had plus the other $7 you said you had. So, $3+$7=$10. You had $10.
Answer:
Y=3x-6
Step-by-step explanation:
You have to put it in point slope form and then put it into slope intercept
Using the t-distribution, it is found that the 95% confidence interval for the population mean rating for Miami is (5.73, 6.95).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
![\overline{x} \pm t\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%5Cpm%20t%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
In which:
is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a <u>two-tailed 95% confidence interval</u>, with 50 - 1 = <u>49 df</u>, is t = 2.0096.
Considering the given sample, the other parameters are given as follows:
![\overline{x} = 6.34, s = 2.16, n = 50](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%3D%206.34%2C%20s%20%3D%202.16%2C%20n%20%3D%2050)
Hence, the bounds of the interval are:
![\overline{x} - t\frac{s}{\sqrt{n}} = 6.34 - 2.0096\frac{2.16}{\sqrt{50}} = 5.73](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20-%20t%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%20%3D%206.34%20-%202.0096%5Cfrac%7B2.16%7D%7B%5Csqrt%7B50%7D%7D%20%3D%205.73)
![\overline{x} + t\frac{s}{\sqrt{n}} = 6.34 + 2.0096\frac{2.16}{\sqrt{50}} = 6.95](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%2B%20t%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%20%3D%206.34%20%2B%202.0096%5Cfrac%7B2.16%7D%7B%5Csqrt%7B50%7D%7D%20%3D%206.95)

Heh, this is a tricky one. This would get you messed up, thinking it'd be 15 hours. But if they worked together, they would go faster, making it simple subtraction, which means 9-6 = 3.
3 hours. Have a great day.
