Answer:
17
Step-by-step explanation:
4a - 4 = 2a + 30
2a = 34
a = 17
X+y=70
x-y=26
add te equations
x+y=70
<u>x-y=26 +</u>
2x+0y=96
2x=96
divide by 2 both sides
x=48
sub back
x+y=70
48+y=70
minus 48 both sides
y=22
the 2 numbers aer 48 and 22
Answer: 9e
Step-by-step explanation:
18,38,38,40,44,44,44,46,48....
the mean with the outlier (18) included is : 360/9 = 40
38,38,40,44,44,44,46,48
the mean with the outlier (18) excluded is : (360 - 18) / 9 = 342/9 = 38
so when the outlier is removed, the mean is 2 points less
2/3 is the answer
the rise is 10
and the slope is 9
simplified it’ll be 2/3
