Answer:

Answer: n is 110

Step-by-step explanation:

Formular:

[tex]mean = \frac{ \sum(n_{1}, \: n _{2}, \: ...n_{n} ) }{n} \\ [/tex]

therefore:

[tex]140 = \frac{(120 + 145 + 130 + 80 + 95 + 100 + 340 + n)}{8} \\ \\ (8 \times 140) = 1010 + n \\ 1010 + n = 1120 \\ n = 1120 - 1010 \\ n = 110[/tex]

Answer:

5 + 8 × 4

Step-by-step explanation:

Answer:

36 tiles

Step-by-step explanation:

Since there is 1 extra tile on each side of the 8x8 pool, we can say that the entire area of the picture is 10x10.

Subtracting 8x8 from 10x10 we get

(10x10) - (8x8) = ?

100 - 64 = 36

36 tiles are around the 8x8 pool

Answer:

XV < XW < WV

Step-by-step explanation:

The side lengths are proportional to angles they see

The side that sees the largest angle has longest measurement and the one that sees smallest angle would be shortest therefore we can order sides from  shortest to longest like this :

XV < XW < WV

Answer:

245 is the answer if you do the math easy

We have the graph of a function (say f(x)).

We have to determine which of the given statements are correct w.r.t this graph of f(x).

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

According to the question, we have the equation of this line as -

y = -5.

The value of y is constant for every value of x. Therefore, the range of the function is Set → {- 5}.

The function has same value → y= -5 for all values of x, ranging from →

- ∞ to + ∞, Therefore, its domain is the set of all Real numbers.

A function can have same value of y for different values of x.

Hence, Option B and D are correct.

Answer:

C. –135

Step-by-step explanation:

Answer:

y = -135

Step-by-step explanation:

y = 15 • 3x

Let x=-3

y = 15 * 3(-3)

y = 15 * -9

y = -135

Step-by-step explanation:

6)

[tex]\boxed{perimeter \: of \: rectangle = 2(length + breadth)}[/tex]

60= 2[½(n -6) +2n +5]

Expand:

60= 2(½)(n -6) +2(2n) +2(5)

60= n -6 +4n +10

Simplify:

60= 5n +4

Minus 4 on both sides:

5n= 60 -4

5n= 56

Divide both sides by 5:

n= 56 ÷5

n= 11.2

Thus, option F is correct.

7)

[tex]\boxed{area \: of \: rectangle = length \: \times breadth}[/tex]

13q +2= 9(q +6)

Expand:

13q +2= 9q +54

Bring q terms to one side, constant to the other:

13q -9q= 54 -2

Simplify:

4q= 52

Divide both sides by 4:

q= 52 ÷4

q= 13

Thus, option B is correct.

Answer:

Step-by-step explanation:

Consider the function and its inverse shown in the second attachment. The function is ...

  f = {(a, 3), (b, 1), (c, 2)}

The inverse function is ...

  f^-1 = {(3, a), (1, b), (2, c)}

You will notice that the "x" and "y" of each pair are swapped between the function and its inverse. That is the point of an inverse function. It gives you the input that caused the function to create the output. For example, the pair (3, a) in the above inverse function tells you that the output 3 was the result of an input of 'a' to the original function.

__

On a graph, the swapping of input and output is essentially equivalent to relabeling the axes. If we keep the same x- and y-axis labels, it is equivalent to reflecting the function graph across the line y=x. That reflection is represented by the transformation (x, y) ⇒ (y, x).

__

The point of the exercise here is for you to identify some ordered pairs of one of the functions and realize that the inverse function reverses their order. You are to see that the graph of the function and its inverse are reflections of each other across the diagonal line y=x.
