Which equation is represented by the graph?

The median number of calls is 235.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

Given;

The data;363, 311, 276, 222, 253, 235, 244

Now to find the median arrangement will be

222,235,244,253,276,311,363

Therefore, the median will be 253

Answer:

The first choice.

Step-by-step explanation:

Domain = x value (first value in a coordinate pair: (x,y))

Range = y value

A function cannot have a repeating Domain value.

This eliminates the last option since -4 is used twice.

The second option has 11 as a y value but it is not in the range.

The third option has 10 as an x value but it is not in the domain.

Slope Formula (Between 2 points)

[tex] \displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }[/tex]

Let these be the following:

[tex] \displaystyle \large{(x_1,y_1 )= (8, - 5)} \\ \displaystyle \large{(x_2,y_2 )= (8 ,- 2)} [/tex]

Substitute these points in.

[tex] \displaystyle \large{m = \frac{ - 2 - ( - 5)}{8 - 8} } \\ \displaystyle \large{m = \frac{ - 2 + 5}{0} }[/tex]

Since the denominator is 0. The slope is undefined. However, we can still find the equation of a line but not in y-isolated form.

Since for all y-values give same x-values. This means that the line will always pass at (8,y) where y is set of real numbers.

The line has to be vertical since a x-value can export many y-values.

Hence, the equation of a line would be x = 8

Answer:

[tex]\huge\boxed{\sf f(4x + 5) = 16x\² + 40x + 25}[/tex]

Step-by-step explanation:

Given that:

f(x) = x²

Put x = 4x + 5

f(4x + 5) = (4x + 5)²

f(4x + 5) = (4x + 5)(4x + 5)

f(4x + 5) = 4x(4x + 5) + 5(4x + 5)

f(4x + 5) = 16x² + 20x + 20x + 25

f(4x + 5) = 16x² + 40x + 25

Answer:

v=-14.4

Step-by-step explanation:

Isolate v.

add - 3.1 to the other side

-7.9+3.1=-4.8

Now the problem is:  -4.8 = v/3

Next, multiply both sides by 3

-4.8 times 3 = -14.4

v = -14.4

Answer:

-14.4

Step-by-step explanation:

-7.9 = -3.1 + (v/3)

- 4.8 = v/3

v = -14.4

Answer:

A triangular prism

Explanation:

The 2 triangles will be the 2 bases and the 3 rectangles will be the 3 sides.

Answer:

First, start by applying the distributive law property to the given equation:  

8x^8(-6x^3+5x^2+5x)

So, it'll go like this --> x (a + b + c) = xa + xb + xc

After you have the equation in this form you will then simplify.  

See the steps below for better understanding.

The amount borrowed from the first and second bank is 19000 and 2000 respectively.

Recall :

Simple interest = P×R×T

Total principal, P = 21000

Bank 1 :

Let, Principal, P = x

Rate, R = 5%

Time, T = 3

Bank 2 :

Principal, P = (21000 - x)

Rate, R = 6.5%

Time, T = 3

Total interest paid = 3240

Bank A interest + Bank B interest = total interest paid

[x × 5% × 3] + [(21000-x) × 6.5% × 3)] = 3240

0.15x + 4095 - 0.195x = 3240

-0.045x = 3240 - 4095

-0.045x = - 855

x = 19000

Hence,

19000 was borrowed from Bank 1

(21000 - 19000) = 2000 was borrowed from bank 2

Answer:

[tex]-3(t+1)(8t-3)[/tex]

Step-by-step explanation:

First, factor both the denominators completely:

[tex]9-24t\\= 3(3-8t)\\= 3(-8t+3)\\= -3(8t-3)[/tex]

[tex]8t^2+5t-3\\= 8t^2+8t-3t-3\\= 8t(t+1)-3(t+1)\\= (8t-3)(t+1)[/tex]

Now, we can see that the factors of the first denominator are -3 and 8t-3.

The factors of the second denominator are t+1 and 8t-3.

To find the LCD, multiply all of these factors together:

[tex]-3(t+1)(8t-3)[/tex]

Notice how we only multiply 8t-3 in the equation once. This is because it was present in both denominators, unlike the other factors.

Answer:

The triangle is isosceles so the two angles in red are equivalent.

This also means that the sides measuring 10 and x are equivalent.

10 = x

Answer:

k(x) = |x - 4| - 2

Step-by-step explanation:

So we know that k(x) is shifted 4 untis to the right and 2 units down. In an absolute value function, the value you move to the left will be positive and the value you move to the right will be negative. Since we are moving to the right, our value will be negative.

When you shift the function up or down, you will either subtract or add that value out side the absolute value. Since we are shifting down 2 units, that means we will be subtracting by 2.

Rational: a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.

A rational number is a number that can be expressed as a fraction with an integer numerator and a positive integer denominator. Two different fractions may correspond to the same rational number. 1/2 = 2/4. Every whole number is a rational number. These can be written as N/1 = N, so they are rational numbers.

Using formula:

[tex]\to \bold{rational\ value =\frac{a+b}{2}}[/tex]

Given:

a=-8

b=-9

Calculating the rational number:

[tex]\to \bold{rational\ number=\frac{-8+(-9)}{2}}[/tex]

                                   [tex]\bold{=\frac{-8-9}{2}}\\\\ \bold{=\frac{-17}{2}}\\\\ \bold{=- 8.5}\\\\[/tex]
