If there are 44 successful outcomes in a sample with a size of 80, what is the
sample proportion?
O A. 0.55
OB. 0.45
O C. 0.36
OD. 0.44
Answer:
The sample proportion is 0.55
Step-by-step explanation:
Given that:
Successful outcomes = 44
Size of sample = 80
We will divide the number of successful outcomes by size of sample to find the sample proportion.
Sample proportion = [tex]\frac{Successful\ outcomes}{Size\ of\ sample}[/tex]
Sample proportion = [tex]\frac{44}{80}\\[/tex]
Sample proportion = 0.55
Hence,
The sample proportion is 0.55
Answer:
0.55

Find the measure of one interior angle in each regular polygon.
Answer:
108°
Step-by-step explanation:
Polygon has n sides.
Each interior angle = 180° - (360/n)°
n = 5 ⇒ interior angle = 180° - (360/5)° = 108°

Complete the missing value in the solution to the equation.
(8,____)
Answer:
The missing value is 5.
Step-by-step explanation:
Since we already have x-value for the equation. What we need to do is to substitute the value of x in the equation.
Substitution
[tex]5x - 2y = 30[/tex]
Then we substitute x = 8 in the equation.
[tex]5(8) - 2y = 30 \\ 40 - 2y = 30 \\ 40 - 30 = 2y \\ 10 = 2y \\ \frac{10}{2} = y \\ 5 = y[/tex]
Answer Check
It is better to check the answer before jumping to the conclusion. We can check if the answer is right by substituting both terms in the equation. If the equation is true then the answer is correct. If the equation is false then one of the term is incorrect.
[tex]5x - 2y = 30[/tex]
Substitute x = 8 and y = 5 in the equation.
[tex]5(8) - 2(5) = 30 \\ 40 - 10 = 30 \\ 30 = 30[/tex]
The equation is true for (8,5)
Therefore, the missing value is 5.
The larger of two numbers is 10 less than twice the smaller number. If the sum of the two
numbers is 38, find the two numbers.
Answer:
Let the larger number = y and the smaller number = x.
The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,
y = 2x - 10
The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,
x + y = 38
Since y = 2x - 10, we rewrite the lower equation as:
x + (2x - 10) = 38
Solving:
3x - 10 = 38
3x = 48
x = 16
The lesser number is 16 and the greater number is 2(16) - 10 or 22.

A researcher is comparing three new formulas for grass killer. To conduct the experiment, the researcher purchases 30 pieces of sod from various vendors to use in the study. The 30 pieces of sod are laid out in three different areas. The researcher places three slips of paper in a bowl labeled formula 1, formula 2, and formula 3 and randomly picks a piece of paper to apply that formula to the sod in the first area. Then the researcher picks again and applies that formula to the second area. Finally, the last formula is used on the last area.
Which component is missing from the researcher’s process?
A The researcher should not have laid out the pieces of sod in different areas.
B The researcher did not randomly assign the pieces of sod to the treatment groups.
C The researcher did not randomly pick the vendors when purchasing the pieces of sod.
D The researcher did not use randomization when selecting the pieces of sod from the vendors.
Answer:
The researcher did not randomly assign the pieces of sod to the treatment groups.
Step-by-step explanation:
Edge 2020/2021
Answer:
The researcher did not assign the chosen pieces of sod to treatment groups.
Step-by-step explanation:
The researcher needs to create three treatment groups, each containing 10 pieces of sod, and assign the chosen pieces of sod to these groups. Without this step, it is not clear how the three formulas will be applied to the pieces of sod.

Answer:
[tex]y = \frac{1}{2}x - 2[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Determine the linear equation
First, we need to calculate the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph, the following relationships exist:
[tex](x_1,y_1) = (4,0)[/tex]
[tex](x_2,y_2) = (10,3)[/tex]
So, the expression for calculating slope becomes:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \frac{3-0}{10-4}[/tex]
[tex]m = \frac{3}{6}[/tex]
[tex]m = \frac{1}{2}[/tex]
Next, we calculate the equation using:
[tex]y - y_2 = m(x - x_2)[/tex]
This gives:
[tex]y - 3 = \frac{1}{2}(x - 10)[/tex]
Open bracket
[tex]y - 3 = \frac{1}{2}x - 5[/tex]
Make y the subject:
[tex]y = \frac{1}{2}x - 5+3[/tex]
[tex]y = \frac{1}{2}x - 2[/tex]

The vertices of the image of GHJK after a translation are given. Choose the vector that describes the translation.
Answer:
Option B
Step-by-step explanation:
Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,
From the graph attached,
Coordinates of G → (-5, 5)
Coordinates of the image point G' after the translation → G'(-5, 5)
Let the point G is translated 'a' units to the right and 'b' units down,
Rule for this translation,
G(x, y) → G'(x + a, y - a)
By this rule,
G(-5, 5) → G'(-5 + a, 5 - a)
-5 + a = -5 ⇒ a = 0
5 - a = 5 ⇒ a = 0
Therefore, vector that defines the translation will be,
<0, 0>
Option B is the the correct option.
The vector that describes the translation of the image is: b. (0, 0).
Recall the rules of translation:
The image attached below shows how an image is translated using a rule.In the image, since we are down to the right, the rule for the translation is given as: [tex](x + x_1, y - y_1)[/tex], where [tex]a[/tex] = units moved to the right, and [tex]b =[/tex] units moved downwards.Thus, from the image given to us showing the image of GHJK, using one of the vertex J' (-3, 3) and the translation rule, [tex](x + a, y - b)[/tex], the vector describing the translation can be determined as follows:
The coordinates of vertex J = (-3, 3)
[tex]x = -3 \\\\ y = 3[/tex]
Substitute[tex]J(-3, 3) = (-3 + a, 3 - b)\\\\-3 = -3 + a\\\\-3 + 3 = a\\\\\mathbf{0 = a} \\\\\\3 = 3 + b\\\\3 - 3 = b\\\\\mathbf{0 = b} \\\\[/tex]
Therefore, the vector that describes the translation of the image is: b. (0, 0).

The ratio of the change in the y and x values, in the table gives the slope
graph of the linear function.
Correct response:
The slope of the linear function is -6Method used for finding the slopeFrom the given table, we have;
The first difference of the y-values = 2 - 8 = -6 = Constant
The rate of change of the x-values = 1 = Constant
Therefore;
The function is a linear function;
The slope, m, is given by the formula;
[tex]Slope, \ m = \mathbf{ \dfrac{y_2 - y_1}{x_2 - x_1}}[/tex]
Taking a pair of points as follows;
(0, -4) = (x₁, y₁)
(2, -16) = (x₂, y₂)
We have;
[tex]m = \dfrac{-16 - (-4)}{2 - 0} = \dfrac{-16 + 4}{2} = \dfrac{-12}{2} = \mathbf{ -6}[/tex]
