Answer:
the bin 60-69 contain the most data values
F
Triangle equals 180
42+42=84
What is 180-84
That would be the next angle
Answer:
Step-by-step explanation:
Definition of negative exponent:
In our case, a = 3 and -n = -2.
Now we just evaluate the power in the denominator.
Answer:
m=6
Step-by-step explanation:
38+8m+4=90
42+8m=90
8m=90-42
8m=48
m=6
This one is best done by elimination:
We need to start 4 meters away, so B is clearly wrong.
We first move towards Mr. Wilson (i.e. distance is decreasing) so A is wrong.
Our speed is faster on the way back, so the two sloped section must have differing slopes, so D is wrong.
(D also doesn't start at 4, it's wrong for two reasons.)
Only C is left.
We can check each part to make sure. First we start at 4m, then move away, then stay still (zero slope) for three seconds, then move back faster (higher slope). All parts check out ok.
