The answer is Relational operators, they are binary operators that evaluate the truthhood or falsehood of a relationship between any two arguments, and that produce  value of true (1) or false (0) as a result.

This is usually done by checking whether a variable is true or false. True values ​​are true values. For example Non-zero numbers, strings, and objects. Incorrect values ​​are the values ​​that correspond incorrectly. lets take 0, empty strings and undefined. By testing whether a variable is true or false, we can also determine whether it equals 1 or 0 without explicitly comparing it to 1 or 0.

This is a useful way to determine the value of a variable without having to write a comparison statement and useful way for determining the value of any variable without being written any comparison statement.

To find 4f(-2) + 5f(1), we need to first find the values of f(-2) and f(1). Using the given equation, we have:

An easy definition of a function

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

f(-2) = -(-2) - 11 = 9

f(1) = -1 - 11 = -12

So, 4f(-2) + 5f(1) = 4 * 9 + 5 * -12 = 36 - 60 = -24.

To find 3f(5) * 2, we need to first find the value of f(5). Using the given equation, we have:

f(5) = -5 - 11 = -16

So, 3f(5) * 2 = 3 * -16 * 2 = -96

To find -5f(12) - 2f(-9), we need to first find the values of f(12) and f(-9). Using the given equation, we have:

f(12) = -12 - 11 = -23

f(-9) = -(-9) - 11 = 2

So, -5f(12) - 2f(-9) = -5 * -23 - 2 * 2 = 115 + 4 = 119

To find f(9)/f(-6), we need to first find the values of f(9) and f(-6). Using the given equation, we have:

f(9) = -9 - 11 = -20

f(-6) = -(-6) - 11 = 5

So, f(9)/f(-6) = -20 / 5 = -4.

The best discrete variable of measurement for the situation is an interval.

Finding the scale of measurement for the variables is the next step in selecting a statistical test after identifying the independent and dependent variables. The dependent variable must be measured using an interval or ratio scale for each of the parametric tests that we have covered so far. Many psychologists also subject variables with roughly interval scales of measurement to parametric tests. You must decide whether to use "scale" or "interval" scores when performing parametric tests of means.

Given the condition about whether the race of the defendant has an impact on jury verdicts,

and measure on a 1 (not at all) to 7 (very) scale how guilty the defendant,

The best scale of measurement for the condition is an interval.

Although the interval scale has characteristics of nominal and ordered data, it also allows for the quantification of data point differences. The variables' actual positions in the order as well as their differences are both displayed by this form of data. They can be combined or split, but not added to or subtracted from. 

The fact that zero is an existing variable adds another characteristic to this scale. Zero in the ordinal scale indicates that there is no data.

Answer:

Step-by-step explanation:

You want the domain and range of the function ...

  F(x) = (x -6)/(x² -3x -18)

We can simplify the function to ...

  [tex]F(x) = \dfrac{x-6}{x^2-3x-18}=\dfrac{x-6}{(x-6)(x+3)}\\\\F(x)=\dfrac{1}{x+3}\quad x\notin\{-3,6\}[/tex]

The domain is the set of x-values for which the function is defined. It is undefined where the denominator is zero. So, x=-3 and x=6 are excluded from the domain, which would otherwise be all real numbers.

The range is the set of values that the function may have. Here, the function can have any y-value except 0 (the value of the horizontal asymptote), and 1/9, the location of the "hole" at x=6.

The range is all real numbers except 0 and 1/9.

Step-by-step explanation:

If Carlos is 6ft tall and looks up at the tree that is 275 ft tall, subtract those two.

275 - 6 = 269

Use tangent with the given angle and the new height. The distance is x.

tan15 = 269/x

x = 269/tan15

x = 1004ft

The distance from Carlos to the tree, given he is 6 feet tall and looks up at a 15° angle of elevation to see the top of a 275-foot tall tree located in Sequoia National Park, is 1026.

Hence option C is correct.

According to the information given,

We can set up a right triangle with Carlos's eye level, the top of the tree, And the base of the tree as the three points of the triangle.

Carlos's height of 6 feet can be used as one side of the triangle,

And we can use the tangent function to find the length of the adjacent side.

A tangent of 15 degrees is equal to the opposite side (height of the tree) divided by the adjacent side (distance from Carlos to the tree).

So, we can solve for the adjacent side by multiplying the height of the tree by the tangent of 15 degrees:

tan(15) = height of the tree / distance from Carlos to the tree

Distance from Carlos to the tree = height of the tree / tan(15)

Plugging in the values given:

Distance from Carlos to the tree = 275 / tan(15)

                                                      ≈ 1026

Therefore,

The nearest foot to the distance from Carlos to the tree is option C. 1026.

Answer:-0.696

Step-by-step explanation:Let the total daily pocket money of the 35 pupils in the other class "A" and the total daily pocket money of all 80 pupils "B".

The mean daily pocket money of the 35 pupils in the other class is m cents, so:

A = 35 * m

The mean daily pocket money of all 80 pupils is 72.25 cents, so:

B = 80 * 72.25

Since we know the total pocket money of both classes, we can use this information to solve for m:

A + B = 115 * m

35 * m + 80 * 72.25 = 115 * m

35 * m = 115 * m - 80 * 72.25

35 * m = 115 * m - 5780

5780 = 115 * m - 35 * m

5780=80 * m

Finally, we can solve for m:

m = 5780/80

m = 72.25

DIVIDE BY 2 to get 50 WOULD GIVE:

20-5x=50-17.5x

Answer:

Yes

Step-by-step explanation:

solve the equation for x , then evaluate and compare both sides

20 - 5x = 50 - 10x ( add 10x to both sides )

20 + 5x = 50 ( subtract 20 from both sides )

5x = 30 ( divide both sides by 5 )

x = 6

then

left side = 20 - 5x = 20 - 5(6) = 20 - 30 = - 10

right side = 50 - 10x = 50 - 10(6) = 50 - 60 = - 10

since both sides are equal then

20 - 5x = 50 - 10x is true
