Answer:
30 yards per minute.
Step-by-step explanation:
Unit rate is basically when the denominator is 1. In this case, 450 is divisible by 15, so if you divide that, you get 30.

Answer:
8 miles
Step-by-step explanation:
I'm going to assume the question said that she "couldn't" repair the tire and was forced to walk back home, that makes more sense.
With that in mind:
She rode her bike 2 miles.
She walked 4 miles on the way there, and 6 miles on the way back.
You can deduce that it was a 6 mile walk back because of the 2 mile bike ride, then the 4 mile walk that it took to get there.
All in all that rounds out to 10 mile walking, and 2 mile biking. That is 8 miles more walking than biking.
Answer:
Step-by-step explanation:
z value of 14.9 = (16.3 - 14.9) / 2
= 0.7
= .7580
z value of 12.9 = (16.3 - 12.9) / 2
= 1.7
=.9554
Required probability = .9554 - .7580
= .1974
or 19.74 % .
Median means middle. How you solve this is by first putting the numbers in order from least to greatest:
36 41 43 45 46 48 48 51 51 52
Now that it is in order in each "level" take away the smallest and largest number until you get to the middle
36 41 43 45 46 48 48 51 51 52
41 43 45 46 48 48 51 51
43 45 46 48 48 51
45 46 48 48
46 48
Now this is a bit tricky because there isn't one number to signify the exact middle. When you have two numbers left you must take the mean of those two numbers. This means that you add the two numbers left and then divide the answer by 2:
46 + 48 = 94
94 ÷ 2 = 47
