For the given table of ordered pairs, the quadratic function is represented in equation in standard form is equal to  y = x² - 14x + 48 .

As given in the question,

From the table of ordered pairs, it is observed that the zeros of the quadratic function are at x = 6 and x = 8. The zeros are the points where the y value of the function becomes zero.

An equation of the function in the standard form is given by :

y = (x - 6)(x - 8)

⇒y = x (x - 8) - 6 (x - 8)

⇒ y = x² -8x -6x +48

⇒ y = x² -14x + 48

The quadratic function is represented as the product of the zeros of the graph when plotted on a Cartesian plane.

Therefore, for the given table of ordered pairs, the quadratic function is represented in equation in standard form is equal to  y = x² - 14x + 48 .

Based on the given ratio, the total number of chocolate chip and oatmeal raisin cookies in the cookie box is 10.

The ratio refers to the numerical relationship that one value or number bears to another.

Ratios are fractional values, showing how much a value is contained in another, or in relation to another.

Ratios are depicted using the ratio sign (:), fractions, decimals, or percentages, like proportions.

The ratio of chocolate chip cookies to oatmeal raisin cookies = 1:4

The sum of ratios = 5 (1 + 4)

The number of chocolate chip cookies in the cookie box = 2

Using the above ratio, there will be 8 oatmeal raisin cookies, that is 2/1 x 4

The total number of cookies (both types) in the cookie box = 10 (2/1 x 5).

Answer:

Josie can by 4 dish sets.

Step-by-step explanation:

Josie’s best friend is getting married and she wants to buy her something from her online wedding registry. She wants to buy some sets of dishes (d) that cost $35 each. Because she’s buying online, she must pay a shipping fee of $10. Josie wants to spend $150 or less. How many sets of dishes can Josie buy?

can be represented by equation:

35d + 10 = 150

subtract 10 from both sides:

35d + 10 - 10 = 150 - 10

35d = 140

divide both sides by 35:

35d/35 = 140/35

d = 4

Josie can by 4 dish sets.

check:

35(4) + 10 = 150

( 2 ) If p and q is 16 then the direct variation is 1

Any time one quantity directly affects the other, such as when one quantity rises relative to the other and vice versa, there is a direct variation between the two variables. It is the relationship between two variables where one of the variables is a fixed multiple of the other. Since the two variables are directly correlated, they are also known as directly proportional.

There are two kinds of proportionalities: direct variation and inverse variation. When two quantities are multiplicatively connected by a constant, the relationship is said to be proportional. In a direct variation, the ratio of the two quantities stays the same, whereas in an inverse variation, the product of the two quantities stays the same.

A number is expressed using scientific notation when it contains a number larger than 1 but less than 10, that multiplies a power of 10

The empty weight of the box = 56.7 grams

The number of feathers added = 940 feathers

Mass of one feather (unit weight) = 0.000567 kilogram

The total weight of the box with the 940 feathers is found as follows;

56.7 grams = 0.0567 kilograms

Mass of the empty box in kilograms = 0.0567 kilograms

Total mass of the 940 feathers 0.000567 × 940 = 0.53298 kilograms

The total weight of the box with the 940 feathers inside is; 0.0567 kilograms + 0.53298 kilograms = 0.58968 kilograms

The mean of the number of shoes according to the obtained results is; 8.49.

The median of the number of pairs of shoes obtained is; 9.

It follows from the complete task content that the mean and median of the data set are to be evaluated;

Since the mean is the average of all obtained data values, it follows from the mean formula;

Mean = Sum Total/Total Frequency

Mean = { ( 8 × 4 ) + ( 4 × 5 ) + .......+ (13 × 4) } / 65

Mean = 552/65

Mean = 8.49.

Also, the median of the set of 65 data values can be guessed to be the 33rd term.

On this note, the data value which corresponds to a cumulative frequency of 33 upon orderly arrangement is the median term.

Hence, since; 8 + 5 + 4 + 4 + 7 = 28; Hence, upon addition of 14, we have; 42.

It is important to note that the sum of angles in a triangle is supplementary.

Also, supplementary angles are defined as pair of angles that sum up to 180 degrees.

Two angles are termed supplementary when they add up to give 180 degrees.

Since, we have that the sum of the interior angles of a triangle are supplementary, then,

Angle A + Angle B + Angle C = 180 degrees

Given the values as;

Now, put or substitute the values into the formula

3x + 10 + 6x + 2x + 5 = 180

collect like terms

3x + 6x + 2x = 180 - 15

Add or subtract like terms

11x = 165

Make 'x' the subject by dividing both sides by the coefficient of x, we have;

11x/11 = 165/11

Find the quotient

x = 15

But we have to find the angles by substituting the value of x

m∠ A = 3x + 10 = 3(15) + 10 = 55 degrees

m∠ B = 6x = 6(15) = 90 degrees

m∠ C = 2x + 5 = 2(15) + 5 = 35 degrees

The first point can be (0, 3), since we know that the y-intercept is 3, i.e., y = 3 for x = 0.

Now, to find a second point we can choose a value for x, let's say x = 1, and use it in the equation of the line to find the corresponding value of y:
