Step-by-step explanation:
the equation for a circle centered at orgin is x^2+y^2=r where r is the radius. multiplying, adding, or subtracting any numbers to the x and y components such as the other choices here causes the circle to be translated about the graph.
Answer:
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 39 - 1 = 38
Now, we have to find a value of T, which is found looking at the t table, with 38 degrees of freedom(y-axis) and a confidence level of 0.99(
). So we have T = 2.0244.
A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
I believe the answer is 17
![y = mx+b\\\\[m is the slope, b is the y-intercept]\\\\y=\frac{2}{3}x+5\\](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb%5C%5C%5C%5C%5Bm%20is%20the%20slope%2C%20b%20is%20the%20y-intercept%5D%5C%5C%5C%5Cy%3D%5Cfrac%7B2%7D%7B3%7Dx%2B5%5C%5C)
That means 2/3 is the slope and 5 is the y-intercept.

Answer:
-20 + 30x
Step-by-step explanation:
-10(1) = -10
-10(-3x) = 30x
new equation
-10 + 30x -10
-10 + -10 = -20
-20 + 30x
