Using the slope concept, it is found that the balloon's vertical distance above the ground is of 437.4 feet.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem:
- The vertical change is x.
- The horizontal change is of 602 ft.
Hence, applying the concept:
tan (36º) = x/602
x = 602 x tan(36º)
x = 437.4.

The answer is 16, the square root of 256 is 16
Answer:
B. x <u>></u> 3
Step-by-step explanation:
-4x - 10 <u><</u> 2
add 10 on both sides
-4x <u><</u> 12
divide by -4
x <u><</u> 3
flip the sign because of the negative is no longer here
x <u>></u> 3
Answer:
0.9985
Step-by-step explanation:
The population standard deviation is:
s² = 64
s = 8
The sample standard deviation is:
σ = s/√n
σ = 8/√39
σ = 1.28
The z-score is:
z = (x − μ) / σ
z = (128.2 − 132) / 1.28
z = -2.97
The probability is:
P(Z > -2.97) = 1 − P(Z < -2.97)
P(Z > -2.97) = 1 − 0.0015
P(Z > -2.97) = 0.9985
