A helicopter is hovering over a landing pad 100 m from where you are standing. The helicopter's
angle of elevation with the ground is 15°. What is the altitude of the helicopter? (Round answer to 2
decimal places)
Answer:
26.79 meters
Step-by-step explanation:
tan15 = x/100
x = 100tan15 ≈ 26.79
Answer is 26.79m
Angle of elevation and tan Formula:
The angle of elevation is the angle between the horizontal line of sight and the object.
The tan angle = the length of the opposite side / the length of the adjacent side.
Here, the angle of elevation is 15 degrees.
Let's altitude of the helicopter is h.
The horizontal distance is 100m
tan(15°) = h / 100
0.2679 = h / 100
=> h = 0.2679 * 100
=> h = 26.79m

In the United States, voters who are neither Democrat nor Republican are called Independent. It is believed that 11% of voters are Independent. A survey asked 33 people to identify themselves as Democrat, Republican, or Independent. A. What is the probability that none of the people are Independent? Probability = B. What is the probability that fewer than 6 are Independent? Probability = C. What is the probability that more than 2 people are Independent? Probability =
Answer:
a) 0.0214 = 2.14% probability that none of the people are Independent.
b) 0.8516 = 85.16% probability that fewer than 6 are Independent.
c) 0.8914 = 89.14% probability that more than 2 people are Independent.
Step-by-step explanation:
For each people, there are only two possible outcomes. Either they are independent, or they are not. For each person asked, the probability of them being Independent voters is the same. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
It is believed that 11% of voters are Independent.
This means that [tex]p = 0.11[/tex]
A survey asked 33 people to identify themselves as Democrat, Republican, or Independent.
This means that [tex]n = 33[/tex]
A. What is the probability that none of the people are Independent?
This is P(X = 0). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
0.0214 = 2.14% probability that none of the people are Independent.
B. What is the probability that fewer than 6 are Independent?
This is
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
[tex]P(X = 1) = C_{33,1}.(0.11)^{1}.(0.89)^{32} = 0.0872[/tex]
[tex]P(X = 2) = C_{33,2}.(0.11)^{2}.(0.89)^{31} = 0.1724[/tex]
[tex]P(X = 3) = C_{33,3}.(0.11)^{3}.(0.89)^{30} = 0.2202[/tex]
[tex]P(X = 4) = C_{33,4}.(0.11)^{4}.(0.89)^{29} = 0.2041[/tex]
[tex]P(X = 5) = C_{33,5}.(0.11)^{5}.(0.89)^{28} = 0.1463[/tex]
[tex]P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.0214 + 0.0872 + 0.1724 + 0.2202 + 0.2041 + 0.1463 = 0.8516[/tex]
0.8516 = 85.16% probability that fewer than 6 are Independent.
C. What is the probability that more than 2 people are Independent?
This is:
[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]
In which
[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{33,0}.(0.11)^{0}.(0.89)^{33} = 0.0214[/tex]
[tex]P(X = 1) = C_{33,1}.(0.11)^{1}.(0.89)^{32} = 0.0872[/tex]
[tex]P(X < 2) = 0.0214 + 0.0872 = 0.1086[/tex]
[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.1086 = 0.8914[/tex]
0.8914 = 89.14% probability that more than 2 people are Independent.

Given that a/b=2/5 and b/c= 3/4. Find a:b:c
Answer:
a:b:c = 6:15:20
Step-by-step explanation:
Given;
[tex]\frac{a}{b} = \frac{2}{5} \ \ and \ \ \frac{b}{c} = \frac{3}{4}[/tex]
a:b:c is determined as follows;
a:b = 2:5 and b:c = 3:4
find the common factors in both equation = b = 5 and 3
Then, multiply the first equation by 3 and second equation by 5, so that value of b in both equations will be the same.
a:b = 6:15
b:c = 15:20
Thus, a:b:c = 6:15:20
39 is 5% of what number?
Answer:
780
Step-by-step explanation:
Explanation:
To get from
5% to 100% you multiply by 20, so multiply the number in this case 39 by 20 percent.
39 is 5 percent of 780.
Given that we need to find 39 is 5% of what number,
To find the number that 39 is 5% of, we can use the concept of proportions.
Let's assume the number we're looking for is represented by "x." We can set up the proportion:
39 is 5% of x
Mathematically, this can be written as:
39 = 0.05x
To solve for x, we divide both sides of the equation by 0.05:
39 / 0.05 = x
The result is:
x = 780
Therefore, 39 is 5% of 780.

Answer: p=-10
Step-by-step explanation:
0.5p=p+5
-p -p
-0.5p=5
Multiply by -0.5 on each side
p=-10
The value of p in 0.5p=p+5 is -10.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
0.5p=p+5
Now, solving for p
For which p from Right side should be moved to left side
0.5p - p= 5
-0.5p = 5
Now, Divide both side by (-0.5)
-0.5p/ (-0.5)= 5/(-0.5)
p = -10
Hence, the value of p is -10.

Answer:
4
Step-by-step explanation:
3. Write an equation for the line that is perpendicular to the given line and that passes through the given point. y = 4x + 1 (12,-6)
a)y = -1/4x + 12
b)y = -1/4x - 3
c)y = -1/4x - 6
d)y= -1/4x + 3
Answer:
D. y = -1/4x + 3
Step-by-step explanation:
If the line is perpendicular, it will have a opposite reciprocal slope.
So, the slope will be -1/4.
Plug in this slope and the given point into y = mx + b, and solve for b:
y = mx + b
-6 = -1/4(12) + b
-6 = -3 + b
-3 = b
Plug in the slope and y intercept into y = mx + b
y = -1/4x - 3
So, the correct answer is D. y = -1/4x + 3
Answer:
D. y = -1/4x + 3

Step-by-step explanation:
The area of the largest squares that will fit on it is 441 square meters.
What is the greatest common factor?The greatest number that can divide the numbers in equal parts.
It is called as greatest common factor.
Given:
An area of land measures 735 meters by 756 meters.
That means,
area of land = 735 x 756
area of land = 555660.
It is to be divided up into square plots of equal size.
HCF of (735, 756),
= 21
Now, the area of the largest square,
= (a)², where a is the side of the square.
That means,
A = 21 x 21
