Answer:
122
Step-by-step explanation:
the real answer is 121.53846153846153, but you wanted to round to nearest percent
The median of the original set is 17 (the two middle numbers are both 17) and the median of the new set is also 17. I could stop here, because only one option says that the median stays the same, but I'll show how the mean increases. The mean of the original set is (10+15+17+17+19+20)/6, which is 98/6, which is 16 and 1/3. The mean of the new set is (10+15+17+17+19+20+200)/7, which is 298/7, which is 42 and 4/7. Therefore, the mean increases and the median stays the same, meaning answer A is correct.
Answer:
y=-2x+16
Step-by-step explanation:
since you are given the slope, you can plug it into the equation y=mx+b where m= slope and b= y intercept
you now have y=-2x+b
to find b, you have to plug in the coordinate you are given into the equation
6=-2(5)+b and solve for b
6=-10+b
b=16
since you now have both the slope & y intercept, you can plug them both back into the original equation, y=mx+b and you get
y=-2x+16
