Brooke decided to ride her bike from her home to visit her friend Adam. Two miles away from home, her bike got a flat tire and s
Naddika [18.5K]

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.

aleksley [76]

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 % .

Please help ASAP first to answer correctly gets brainlyist
Anna11 [10]

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

Hope this helped!
