Answer:
A = 3,-1
B = 2, 4
C = -3, 0
D = 1,-1
Step-by-step explanation:
First, you should know that the first number is the x axis, and the second number is the y axis. You ALWAYS find the x axis first. Next, you start from the origin point, 0. 0 is where the two lines meet. Starting from 0, you move the point three spaces to the right, and one down to get to point A. So, the coordinate would be 3,-1. For point B, you would move two points to the right, and 4 down. That brings you to 2,4 the coordinates for point B. Do the same things for C and D. Go three spaces left, and stay there. That would be -3,0. For D, go right 1, and one down. Remember UP and RIGHT = Positive, DOWN and LEFT = Negative. Hope this helped!

<u>Step-by-step explanation:</u>
1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.

Answer: The maximum error = $105.76.
Step-by-step explanation:
Formula to find the maximum error:
, where n= sample size.
= Population standard deviation
z*= Critical value(two-tailed).
As per given , we have
n= 35
For 98% confidence , the significance level = 
By z-table , the critical value (two -tailed) =
Now , the maximum error = 
Hence, With 98% confidence level , the maximum error = $105.76.
The radius is 8.5. It is just the diameter cut in half btw for any future questions.
