Answer:x=13.42

Step-by-step explanation:

from Pythagoras principle we have

x^2=√(18^2-12^2)

x^2=√(18x18-12x12)

x^2=√(324-144)

x^2=√(180)

Take the square root of both sides

x=13.42

Select the correct comparison set a set b O A the typical value is greater is set a the spread is greater in set b

salantis [7]

Answer:

(a)

Step-by-step explanation:

Given

See attachment for sets A and B

Required

The true statement about both sets

First, we calculate the typical values (mean) of set A and set B.

This is calculated as:

$Mean = \frac{\sum fx}{\sum f}$

For A:

$A= \frac{0*1+2*1+5*1+6*1+7*1}{1+1+1+1+1}$

$A= \frac{20}{5}$

$A =4$

For B:

$B = \frac{7 * 1 + 8 *1 + 9 * 2 + 10 * 1}{1+1+2+1}$

$B = \frac{43}{5}$

$B = 8.6$

Here, we can conclude that B has a larger typical value

Next calculate the spread (range) of sets A and B

This is calculated as:

$Range = Highest -Least$

For A:

$A = 7 - 0$

$A = 7$

For B

$B=10 - 7$

$B = 3$

Here, we can conclude that A has a larger spread.

Hence, (a) is true

A plane is at cruising altitude of 10,200 feet. If the angle of depression to the run way is 18 degrees, what is the distance, t

MatroZZZ [7]

Answer: $33,007.9\ ft$

Step-by-step explanation:

Given

The plane is cruising at an altitude of $h=10,200\ ft$

The angle of depression is $\theta=18^{\circ}$

Suppose the distance of the plane to the runway is x

from figure

$\Rightarrow \sin 18^{\circ}=\dfrac{h}{x}\\\\\Rightarrow \sin 18^{\circ}=\dfrac{10,200}{x}\\\\\Rightarrow x=33,007.9\ ft$
