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

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.

"It is a triangle in which one of the angle measures 90° "

"It is the longest side of the right triangle."

"For a right triangle, [tex]x^{2}+ y^{2}=z^{2}[/tex], where z is the hypotenuse and x, y are other two sides of the right triangle."

"In a right triangle, csc of angle is the ratio of the hypotenuse to the opposite side of angle."

For given question,

First we find the hypotenuse of the right triangle.

Using Pythagoras theorem,

[tex]\Rightarrow 9^{2} + 12^{2}= r^{2}\\\\ \Rightarrow 81 + 144=r^2\\\\\Rightarrow r=\sqrt{225}\\\\ \Rightarrow r=15[/tex]

so, the hypotenuse is r = 15

Now we find the csc of angle [tex]\theta[/tex]

[tex]\Rightarrow csc(\theta)=\frac{hypotenuse}{opposite~side~of~\theta} \\\\\Rightarrow csc(\theta)=\frac{15}{12}[/tex]

Therefore, the value of [tex]csc(\theta)[/tex] is [tex]\frac{15}{12}[/tex]

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),

Step-by-step explanation:

Answer:

mmmm. give it to. meeee.

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.

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

Answer:

25.47, 25.09

Step-by-step explanation:

looking at only the tenths they round down to 25.

The numbers that would round off to 25 when rounded to the nearest whole number are 25.09 and 24.49.

When one is to round off to the nearest whole number, the numbers after the decimal point are to be eliminated.

To round off to the nearest whole number, if the tenth figure is equal to 5 or greater than 5, 1 would be added to the unit term, if this is not the case, zero would be added to the unit term.

When 25.09 and 24.49 are rounded off to the nearest whole number, it becomes 25

Answer: p=-10

Step-by-step explanation:

-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.

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
