Answer:
C
Step-by-step explanation:
He had 0 then he added 227.11 and so he had 227.11 in his bank account then he took out the money so he was back at 0 so the answer is c
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:
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 25 - 1 = <em>24 df</em>, is t = 2.0639.
The other parameters are given by:
.
Hence, the bounds of the interval are given as follows:
The 95% confidence interval is (29.6, 44.4).

Answer:
y = -2x - 6
Step-by-step explanation:
Use slope-intercept form to start the equation. y2 - y1 / x2 -x1
-6 - 0 / 0 - (-3) = -6 / 3 = m = -2
Then plug m (-2) into your y=mx+b equation.
y = -2x + b
substitute -6 for y value and 0 for x value to find value of b.
-6 = -2(0) + b
simplify
-6 = 0 +b
subtract 0 from both sides
-6 = b
plug b value back into the equation
final equation of line is: y = -2x -6
