Answer:
By using the formula:
*b*h
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1

Answer:
The mean
Step-by-step explanation:
Given :
Miles traveled : 216 210 250 225 209
Ordered data : 209, 210, 216, 225, 250
Mean = Σx / n
Sample size, n = 5
Mean = (216 + 210 + 250 + 225 + 209) / 5
Mean = 222 (mean for the 5 weeka.
The median :
1/2(n+1) th term = 6/2 = 3rd term
.Median = 216
Adding week 6 data:
209, 210, 216, 225, 250, 406
Mean = ( 705/ 6) = 192
Median :
1/2(n+1) th term = 7/2 = 3.5 th term
.Median = (216 +. 225) /2 = 220.5
The mean changes more :
220 - 192 = 28
Median :
220.5 - 216 = 4.5:
