There are 253,440 inches in 4 miles. If you divide this quantity into the 24 inch strides she takes, you get your answer of 10,560 strides.
Hope this helps! <3
Answer:
1. 6x + 2y = 25.92
4x + 3y = 33.93

This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone
To be able to determine the type of skew exhibited by the distribution of the heights he achieved in each of his attempt we arrange the distribution in order and obtain the frequency of each data in the distribution. Height (meters): 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 Frequency: 2, 1, 1, 2, 2, 3, 1, 2, 1, 1, 1, 1, 1, 1 Calculating the mean gives (11 x 2 + 12 + 13 + 14 x 2 + 15 x 2 + 16 x 3 + 17 + 18 x 2 + 19 + 20 + 21 + 22 + 23 + 24) / 20 = 335 / 20 = 16.75 Since there are more higher frequencies to the left of the mean we conclude that the distribution exhibits a positive skew.
