binder: Liquid substance used in paint and other media to bind particles of pigment together.

fresco: Where pigments are mixed with water and then applied to a plaster support, usually a wall or a ceiling.

gouache: A type of watercolor in which white pigment is added creating a duller effect, and a tinted feel.

oil: Painting medium where pigments are binded using oils, usually linseed oil.

painting media: Material made of three components; pigment,vehicle, and binder

pigment: Ground up solids that contain color the color in paint.

tempera: A water based painting medium made with egg yolk, often used to paint frescos and panels.

vehicle: Adjusts the viscosity of the paint.

watercolor: Pigment that is mixed with arabic and gum, and mostly water before it is applied to the paper.

the mean of a set of numbers is 120. if one number is increased by 300, the mean increases to 135. how many numbers are in the s

stiks02 [169]

There are 20 numbers in the set.

Given,

Set of numbers is 120

one number is increased by 300

and, mean increases to 135.

To find the how many numbers are in the set?

Now, According to the question:

Let the number of numbers be 'n'

Then, (sum of numbers)/n = 120

or, old sum = 120n

if one number is increased by 300, the new sum = (old sum + 300)

Then, (new sum)/ n= 135

or new sum = 135n = old sum + 300 = 120n + 300

The equation will be:

135n = 120n + 300

15n = 300

n = 20

Hence, There are 20 numbers in the set.

In the question:

The mean of a set of numbers is 120. if one number is increased by 300, the mean increases to 135.

Which of the following equations could represent the points in the table? Select all that apply.

schepotkina [342]

Answer:

Options (A) and (C)

Step-by-step explanation:

From table attached,

Let the equation of a linear equation that represents the input-output values in the table is,

y - y' = m(x - x')

Where (x', y') is a point lying on the graph.

And m = slope of the line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$

m = $\frac{y_2-y_1}{x_2-x_1}$

Slope of the line passing through (0, 11) and (1, 5) will be,

m = $\frac{11-5}{0-1}$

m = -6

Therefore, equation of the line passing through (0, 11) and slope = -6 will be,

y - 11 = -6(x - 0)

Equation of a line passing through (1, 5) and slope = -6 will be,

y - 5 = -6(x - 1)

Equation of a line passing through (2, -1) and slope = -6 will be,

y + 1 = -6(x - 2)

Equation of a line passing through (3, -7) and slope = -6 will be,

y + 7 = -6(x - 3)

Therefore, Options (A) and (C) are the correct options.
