Answer: The distance between the birds is about 77.78 yards.
This is a trigonometry problems, so it helps to draw a right triangle between the birds. The length between them is the hypotenuse and we have a angle of 40 degrees by the sparrow. The side opposite the sparrow is the difference in heights of the birds, 50 yards.
Therefore, we can write and solve the following sine relationship.
sin(40) = 50/x
0.6428 = 50/x
x = 77.78 <span />
Answer:
(MAD) mean absolute deviation: 114.2
Step-by-step explanation:
Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164
164 - 62 = 102
164 - 71 = 93
164 - 83 = 81
164 - 110 = 54
164 - 501 = 337
164 - 94 = 70
164 - 227 = 63
Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 = 114.2
Answer: well if p= $1000 and t=6 and r-11 % then 6k+11=1000 then 11- 1000 is 6k=989 divide 6/ 164.83 i think
