Answer:
use your calculator
Step-by-step explanation:
To calculate the Linear Regression (ax+b): Press [STAT] to enter the statistics menu. Press the right arrow key to reach the CALC menu and then press 4: LinReg(ax+b). Ensure Xlist is set at L1, Ylist is set at L2 and Store RegEQ is set at Y1 by pressing [VARS] [→] 1:Function and 1:Y1.
A theorem called "inscribed angle theorem," states that angle θ is half of that of angle 2θ that subtends an identical arc on the circle.
So, ∠ABC = center angle * 1/2
The center angle is 192°, so substitute with that number and solve.
∠ABC = 192 * 1/2
∠ABC = 96°
Therefore, the answer is 96°
Best of Luck!

Answer: 8/12% 6/11%
Step-by-step explanation: so 4 red marbles and 8 blue marbles so in total that's 12 marbles so if you have 8 blue marbles you have a 3/4 chance of getting blue but only 1/4 chance of red
So 5 green marbles and 6 yellow marbles so in total that's 11 marbles so if you have 6 yellow marbles you have a 3/4 chance of getting yellow but only 1/4 chance of green
2y+x-2y+3x=180
x=45
2x-15=-2y+3x
y=30
