Answer:

2200 feet

Step-by-step explanation:

1. Find necessary angles

45˚ + 45˚ = 90

so airplane and height is 45˚ in between

d = distance

cos 45 = 2200/d

d = 2200/cos 45

d ≈ 3111.27 > all of the answers

If it is from ground to house then its 2200 ft, same as plane to ground

prohojiy [21]

Answer:

Sample = 1046

Population = All adults.

In Statistics, a sample can be defined as a set of items, objects or individuals collected, selected or drawn from a population. Thus, a sample is a subset of a population. In this scenario, the sample is 1046.

On the other hand, population can be defined as the total number of individuals in a survey. Thus, all the adults are a population.

The best way to solve this is by giving a visual idea of the glass ornaments. so We will have letter G represent Green, O for Orange, B for Brown, P for Purple.
Sample 1:G,O,B,P
Sample 2:G,P,O,B
Sample 3:P,G,O,B
Sample 4:O,G,P,B
Sample 5:G,O,P,B
This is what you can do this should be the right amount of ways to arrange them.

<em>Answer:</em>

∠WVR = 156

<em>Step-by-step explanation:</em>

Angles in a triangle add up to 180

∴ ∠SRT + RST + RTS = 180

∴ ∠SRT + 109 + 47 = 180

∠SRT = 24

Alternate Angle Theorem

∠SRT = 180 - ∠WVR

24 = 180 - ∠WVR

24 - 180 = - ∠WVR

-156 = - ∠WVR

∠WVR = 156

Have a beautiful day.
