Answer:
1731 ft
Step-by-step explanation:
The tangent relation is useful in this problem.
Tan = Opposite/Adjacent
The height of the light is found to be ...
tan(11°) = height/(639 ft)
height = (639 ft)·tan(11°) . . . . . solve for height
Then the distance from the light to point B is ...
tan(3°) = height/(B distance)
B distance = height/tan(3°) = (639 ft)·tan(11°)/tan(3°) ≈ 2370 ft
Then the distance from point A to point B is ...
2370 ft -639 ft = 1731 ft . . . AB distance
Step-by-step explanation:
2x-y= -1
x-2y= -8
eqn2*2=2x-4y= -16
eqn3- eqn1
-3y=- -15 y=5
2x-5= -1
2x=4 x=2
The answer is A LOL good luck;)
Hello!
We know that there is a 1/2 chance of selecting either color. Let's say that the numerator represents red and the denominator represents black. We have a 1/2 chance of picking a red card overall. In this scenario, we have the event of 2/3. If we multiply these fractions we get 2/6, which is equal to 1/3.
The probability is 1/3.
I hope this helps!
The correct answer is A. The 200 randomly selected students
Explanation:
In most studies, the complete population is not surveyed or studied instead, a specific number of individuals are selected, this group is known as the sample. Additionally, the sample represents the population, and due to this, their answers are used to make inferences about all the population.
According to this, the population is all the students in the school, while the sample is the 200 randomly selected students because this is the group that is going to be studied to make conclusions and inferences about all the population.
