What is direct variation?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.

What is the mean and median of the frequency distribution?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;

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

How to find alternate angles?Alternate angles are defined as the angles that occur on opposite sides of the transversal line and have the same size. Thus, Alternate angles are always equal.
These interior alternate angles can be gotten by drawing a Z shape which produces two different types of alternate angles namely alternate interior angles and alternate exterior angles.
Now, we are given that only one known angle in the image which is 80°. However, we see that the angle we want to find which is angle 4 is an alternate angle to the known angle.
Thus, by definition of alternate angles, we can say that ∠4 = 80°

weight of 0.000567 kilogram in the box, find the total weight, in kilogram,
of the box with 940 feathers inside. Write your answer in scientific notation.
Round the coefficient to the nearest tenth.

Answers
The sum of the weight of the empty box and the 940 feathers is approximately [tex]5.90 \times {10}^{ - 1} [/tex] kg.
What is a scientific notation?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 total weight of the box and the feathers = 0.58968 kilograms =
[tex]5.8968 \times {10}^{ - 1} [/tex]
kilograms
Rounding the coefficient to the nearest tenth gives;
The total weight of the box and the feathers is approximately [tex]5.90 \times {10}^{ - 1} [/tex] kilograms

What is the y-intercept? Select the correct choice below and fill in any answer boxes within your choice.
Answers
We have the relation:
y = 4x + 3
Since the slope (4) and the y-intercept (3) were already found, we need now to graph this line.
In order to do so, we can find two points belonging to this line and then draw a line that passes through those points.
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:
y = 4x + 3 , x = 1
y = 4 * 1 + 3
y = 4 + 3
y = 7
So, (1, 7) is another point we can use.
Now, we can select the second button on the toolbox to draw a line through the points (0, 3) and (1, 7):
