Which of the following are true of the sample of 40 voters? Check all that apply.
The sample is not randomly chosen.
The sample should be larger to give more reliable information.
The sample size is too large to make inferences.
The sample size is too small to represent the population.
The sample size is too small and will show larger variation.
The sample is invalid because it randomly chooses voters.
The sample size is too small and can lead to false inferences.
Makayla can type 360 words in 8 minutes. At
this rate, how many words can she type in
3 minutes?
Answer:
135
Step-by-step explanation:
360/8=45
so she can type 45 words a minute
45 x 3=135 words in 3 minutes
Step-by-step explanation:
no. of words she can write in 8 mins = 360
no. of words she can write in 1 min = 360/8
no. of words she can write in 3 mins = 360/8*3 = 135 words

What is the area of the triangle whose vertices are (-4,0), (-10, 0) and (-7,-6)?
Step-by-step explanation:
From the point -10 to -4, there is a difference of 6 units. Base = 6
From the x-axis to the furthest point, there is a difference of 6 units. Height = 6
6*6 = 36
36/2 = 18
Area = 18
Determine whether the following equation represents a direct variation If it does, find the constant of variation
2x + 3y = 0
Given:
The equation is
[tex]2x+3y=0[/tex]
To find:
Whether the equation represents a direct variation. If it does, find the constant of variation.
Solution:
The general equation of direct variation is
[tex]y=kx[/tex] ...(i)
Where, k is the constant of variation.
The equation of direct variation is always true for (0,0).
The given equation is
[tex]2x+3y=0[/tex]
It can be written as
[tex]3y=-2x[/tex]
[tex]y=-\dfrac{2}{3}x[/tex] ...(ii)
For x=0,
[tex]y=-\dfrac{2}{3}(0)[/tex]
[tex]y=0[/tex]
The given equation is true for (0,0). So, it represents a direct variation.
On comparing (i) and (ii), we get
[tex]k=-\dfrac{2}{3}[/tex]
Therefore, the constant of variation is [tex]-\dfrac{2}{3}[/tex].

Answer:
x = 1 y = -3 (1, -3)
Step-by-step explanation:
Use the Substitution Method
First, you have to turn the equations into slope intercept form (y = mx + b)
First equation
x - y = 4
subtract x from both sides
-y = -x + 4
divide each side by -1
y = x - 4
Second Equation
4x + y = 1
subtract 4x from both sides
y = -4x + 1
Turn the two new equations into one equation like so
-4x + 1 = x - 4
add 4x to both sides
1 = 5x - 4
add 4 to both sides
5 = 5x
divide each side by 5
x = 1
Fill in x in one of the original equations in order to find the value of y
4(1) + y = 1
4 + y = 1
subtract 4 from both sides
y = -3
The solution is (1, -3)hope this helps :)

Executive leadership wants to survey employees at a grocery store that is open 24 hours a day. They are interested in getting surveys from people from every job title (cashier, stocker, manager, etc.) Which of the following uses systematic random sampling?
Survey 3 randomly chosen cashiers, then repeat that process with the stockers, managers, etc.
Randomly select 1 of the 3 shifts (morning, afternoon, or night), and survey all the employees who work that shift.
List all of the employees by their employee ID number. Have the computer randomly select 25 of the numbers, and survey those employees.
List all of the employees by their employee ID number. Survey the 11th person on the list (with the number 11 being randomly chosen), then survey every 10th person on the list after that.
Answer:
(D) List all of the employees by their employee ID number. Survey the 11th person on the list (with the number 11 being randomly chosen), then survey every 10th person on the list after that.

Explanation:
This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.
The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.
Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.

Which expression is equivalent to the given expression?
(3m-4) (375)
9514 1404 393
Answer:
D. 81/m^7
Step-by-step explanation:
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b
__
Using these, your expression simplifies to ...
[tex](3m^{-4})^3(3m^5)=(3^3)(3)(m^{-4\cdot3+5})=81m^{-7}=\boxed{\dfrac{81}{m^7}}[/tex]

Answer:
C) 4(5c -2d)
Step-by-step explanation:
You would need to find the greatest commen factor in the equation.
it would end up being 4 since it is the biggest number that can divide between 8 and 20.
20/ 4 = 5
8/4 = 2
so you would leave the varibles since you can't take them out and put 4 on the outside of the parantheses.
4(5c -2d)
Answer:
Option C: 4(5c -2d)
