Answer:
f = -4
Explanation:
Subtract The Numbers: -2 - 2 = 4
f = -| -4|
Apply Absolute Rule (|-a| = a): |-4| = 4
f = -4
I'd go with Checking account B because its cheaper .
To get the answer for this problem your going to have to show us the frequency table
First, let's convert X into 4
(3*4 - 4)ft, (4*2 - 1)ft, (2*4*2 - 15)ft
Now lets simplify this a little
(12 - 4)ft, (8 - 1)ft, (16 - 15)ft
Awesome now lets finish up
8 x 9 x 1 / 2 = 36
The answer should be 36ft. Unless I did my math wrong.
The expression relating the distance and the time is:
velocity = distance / time
We are given the velocity as 12 km/h
Part a:
for t = 3.5 hours
velocity = distance / time
distance = velocity x time
distance = 12 x 3.5 = 42 km
Part b:
for s = 30 km
velocity = distance / time
time = distance / velocity
time = 30 / 12 = 2.5 hours
