Answer:
Triangle
Step-by-step explanation:
cross section through the cone perpendicular will be a triangle with the base of the cone's base diameter.
You should look to units of measure when setting up problems. when math is done correctly, the units cancel out just as numbers and variables do.
(miles / hr) * hr = miles
Speed = (miles / hr)
So if the Train W is traveling at x miles/hr
Then Train E is traveling (x+14) miles/hr
The combined distance they two trains travel is 320 miles
2x + 2(x+14) = 320
2x + 2x + 28 = 320
4x + 28 = 320
4x = 292
x = 292/4
x = 73 miles/hr
remember we set x as the speed for Train W
so Train E is going 73 + 14 = 87 miles/hr
Answer:
That would be a fairly weak positive correlation.
Step-by-step explanation:
If you start in the origin and go up, the correlation is positive.
This would be fairly weak because the points are pretty scattered. If it were strong, you could almost draw the line of best fit by yourself. Here you can't.
Answer:
-19x-14
Step-by-step explanation:
Just distribute. It's simple
Same reasoning as in my previous answer, so the period is 15-1=14
