10 yards. The amount of yards is 1 third the amount of feet so you just divide 30 by 3 to get the amount of yards
Answer:
The approximate length of the diagonal walkway is 21.21 meters
Step-by-step explanation:
we know that
Applying the Pythagorean Theorem in the square park, find out the the approximate length of the diagonal walkway
so
where
c is the diagonal of the square
a and b are the length sides of the square
we have
substitute
therefore
The approximate length of the diagonal walkway is 21.21 meters
The answer is Letter D - 84%
68% of the data is within +/- 1 SD from the mean = 59 to 7195% of the data is within +/- 2 SDs from the mean = 53 to 7799.7% of the data is within +/- 3 SDs from the mean = 47 to 83
The whole 68% (59 - 71) scored below 71. Since the data are evenly distributed, we'll get the 32% (100 - 68) outside the range of 68% and divide it by 2 and add the quotient to the original 68% so that we'll get the total data below 71.
100 - 68 = 32
32 / 2 = 16
16 + 68 = 84
