Step-by-step explanation:
3х + 2y = 14
3х - 2y = 10
6x=24
x=4
3×4+2y=14
12+2y=14
2y=14-12
2y=2
y=1
60.38 is the answer to this
Answer:
slope: -1/2
Y-intercept: -1
Step-by-step explanation:
Get Y by itself by subtracting x on both sides
2y= -x -2
Now divide both sides by 2 to cancel the two connected to the y:
Y = -1/2x -2/2
So y= -1/2x -1
Y=mx+b so m is the slope and b represents the y-intercept
Answer:
Follows are the solution to this questrion:
Step-by-step explanation:
In point a:
Nominal -scale
Qualitative -Variable
In point b:
Table of frequency
Frequency of results
early =22
On time =68
Late =7
Lost= 1
In point c:
Relative list of frequencies (about two decimal places)
Frequency of results
Early =0.23
On time =0.69
Late = 0.07
Lost = 0.01
In point d:
Early or early packing packets =92%
packages missing= 1%
6(2x-3) = 72+8x
12x-18=72+8x
12=72+8x
4x=90
4/4 90/4
x=22.5
x=22.5
