A ski run is 1200 yards long with a vertical drop of 308 yards.  Find the angle of depression from the top of the ski run to the
balu736 [363]

Answer:

The vertical drop created an angle of 90 degrees.

Therefore, you have a right triangle.

Let's name the ski run AB, and the vertical drop BC.

Angle B would be 90 degrees.

We have two measurements AB = 1200 and BC = 308 so we can find the third measurement AC by doing pythagoras:

1200^2 + 308^2 = 1239 yards

now with the sine law

1239/sin90 = 308/sin(angle of depression)

angle of depression = sin-1(308 x sin90/ 1239) = 14.4 degrees

Answer:

\bar{x}=61.98

Step-by-step explanation:

The sample mean \bar{x} is a point estimate of the population mean μ.

Given the heights of the 6 tomato plants sample below:

55.6, 59.4, 59.9, 62.9, 64.9, 69.2

Point Estimate,

\bar{x}=\dfrac{55.6+59.4+59.9+62.9+64.9+69.2}{6} \\=\dfrac{371.9}{6} \\\bar{x}=61.98
