Answer:
(4,4)
Step-by-step explanation:
The midpoint is found by using
xm = (x1+x2)/2 = (2+6)/2 = 8/2 =4
ym = (y1+y2)/2 =2 =(6+2)/2 = 8/2 =4
The midpoint (xm,ym) = (4,4)

Answer: The data point 25 lies in the first quartile of the date
Step-by-step explanation: The data point 25 is not in the data set.
Carl has 35 dimes and 90 quarters
Let the number of quarters be q and the number of dimes be d
Total number of coins is 125;
Hence;
q + d = 125 •••••••••(i)
The total value of quarters present = q * 0.25 = 0.25q
The total value of dimes present = d * 0.1 = 0.1d
Adding both gives the total
0.25q + 0.1d =26 ••••••••(ii)
So we need to solve both equations simultaneously;
From i,
q = 125 - d
Substitute this into ii
0.25(125-d) + 0.1d = 26
31.25 -0.25d + 0.1d = 26
31.25 -26 = 0.25d -0.1d
5.25 = 0.15d
d = 5.25/0.15
d = 35
Recall; q = 125 - d = 125 -35 = 90
Hey!
Hope this helps...

Assuming that the sum of all the angles must equal 180°
180 - (27+10) = k
180 - 37 = k
k = 143°
