Answer: -1/8
Step-by-step explanation:
3/4 + -3/8 + -1/4
Find the LCM of 4, 8, and 4
That's 8 so you make an equivalent fraction for all fractions so the denominator is 8.
3/4 = 6/8
-3/8 = -3/8
-1/4 = -4/8
Now the expression looks like this:
6/8 + - 3/8 + -4/8
6/8 - 3/8 - 4/8
6/8 - 7/8
-1/8

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.
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

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]

B) 7x^2y^4(x−y)
C) 7(x^3y^4−x^2y^5)
D) x^2y^4(7x−7y)
Answer:

Step-by-step explanation:
when we factor completely, we take a look at what is the biggest common factor of 7x³y⁴ and 7x²y⁵. In this case it is 7x²y⁴.
7x³y⁴-7x²y⁵ = 7x²y⁴(x-y) which is B.
In a survey of school students, 64 had taken mathematics course, 94 had taken chemistry course, 58 had taken physics course, 28 had taken mathematics and physics, 26 had taken mathematics and chemistry, 22 had taken chemistry and physics course, and 14 had taken all the three courses. Find how many had taken one course only by using Venn diagram.
Answer:

Step-by-step explanation:
The number of students taken only one course is 106
What is Venn diagram?A Venn diagram exists as an illustration that utilizes circles to illustrate the relationships among things or finite groups of things. Circles that overlap include a commonality while circles that do not overlap do not share those traits. Venn diagrams permit visually illustrating the similarities and contrasts between two concepts.
Let M =sets of students who had taken mathematics
C= sets of students who had taken chemistry
P= represent sets of students who had taken physics
From the given information, we have
n(M) = 64 , n(C) = 94, n(P) = 58,
n(MnP) = 28, n(MnC) = 26, n(CnP) = 22
n(MnCnP) = 14
No. of students who had taken only Math :
= n(M) - [n(MnP) + n(MnC) - n(MnCnP)]
= 64 - [28+26-14]
= 64 - 40
= 24
No. of students who had taken only Chemistry
= n(C) - [n(MnC) + n(CnP) - n(MnCnP)]
= 94 - [26+22-14]
= 94 - 34
= 60
No. of students who had taken only Physics
= n(P) - [n(MnP) + n(CnP) - n(MnCnP)]
= 58 - [28+22-14]
= 58 - 36
= 22
Total no. of students who had taken only one course
= 24 + 60 + 22
= 106

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]

Answer:
−31π/36 = -15.5°
Step-by-step explanation:
We need to convert −31π/36 to degrees.
The conversion from radian to degrees is calculated as follows :
[tex]\text{Degrees}=\dfrac{180}{\pi }\times \text{radian}\\\\=\dfrac{180}{\pi}\times \dfrac{-31\pi }{360}\\\\=-15.5^{\circ}[/tex]
So, −31π/36 is equal to -15.5 degrees.

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.
