iranda is conducting a poll to determine how many students would attend a students-only school dance if one was held. Which sample is most likely to yield a representative sample for the poll? twenty names from each grade pulled blindly from a container filled with the names of the entire student body written on slips of paper every tenth person walking down Main Street in town at different times of the day all of the students who write into the school newspaper every student from all of Miranda’s classes
Answer: 20 names from each grade
Step-by-step explanation:
The two answers it comes down to are between every student from all of her classes and 20 students from each grade, however since the poll wants to determine how many people across the entire student body would attend, pulling from just Miranda's classes would add a grade level bias to the dance and would not be entirely random. 20 students from each grade is completely unbiased and properly represents the entire student body.
Answer:
20 names each grade
Step-by-step explanation:
in a controlled laboratory environment a random sample of 10 adults and a random sample of 10 children were tested by a psychologist to determine the room temperature that each person finds most comfortable. The data are summarized below.
Simple Mean Simple Variance
Adults(Population 1) 77.5°F 4.5
Childerns(Population 2) 74.5°F 2.5
If the psychologist wished to test the hypothesisthat children prefer warmer room temperature than adults, which hypothesis would he use?
Answer:
F distribution test
Step-by-step explanation:
He would use the F distribution test. This test is used in comparing the variances of two categorical variables if they are equal. The null hypothesis is rejected if after carrying out the test the results states otherwise.
Match the equivalent expressions 3x+5x+8, 4x+4x, 4x+4x+4x+4x, -7x + 4 + 3x, 8x, 16x, -4x + 4 and 8x + 8
Answer:
Combine like terms; 3x + 5x= 8x
Since you don't have any like terms for +8, it's going to remain the same and not change.
Answer : 3x + 5x + 8 = 8x + 8
Again with combining like terms, 4x + 4x = 8x
Answer: 4x + 4x = 8x
The third expression is going to be very similar to the last problem. 4x + 4x + 4x + 4x. We're going to add the terms together. 4+4+4+4 is equal to 16. Bring the x down and you get...
Answer: 16x
Lastly, we have -7x + 4 + 3x. Do the exact same thing we did to the other problems, combining like terms, shocking, I know. -7x + 3x= -4 and since there's no other like terms for +4, it stays the same. Therefore
Answer: -7x + 4 + 3x = -4 + 4

Hi my lil bunny!

Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14 or 22/7.
` OR `
Plug the given value of the diameter into the formula and solve.[2]
Example problem: You have a circle tub with a diameter of 8 feet, and you want to build a white fence that creates a 6-foot wide space around the tub. To find the circumference of the fence that has to be created, you should first find the diameter of the tub and the fence which will be 8 feet + 6 feet + 6 feet, which will account for the entire diameter of the tub and fence. The diameter is 8 + 6 + 6, or 20 feet. Now plug it into the formula, plug π into your calculator for its numerical value, and solve for the circumference:
C = πd
C = π x 20
C = 62.8 feet

If the following data files were stored as raster data, what data would be considered discrete and which would be continuous: rainfall, soil type, voting districts, temperature, elevation, and vegetation type? Justify each choice.
Answer:
Rainfall: Continuous
Soil type: Discrete
Voting districts:Discrete
Temperature:Continuous
Elevation: Continuous
Vegetation type:Discrete
Step-by-step explanation:
Discrete data is one that involves round, definite numbers that can be determined by just counting whereas continuous data is one that involves complex numbers that are usually measured across a specific time interval. In a nutshell, we can say that discrete data is one that is counted while continuous is one that is measured.
Rainfall: This will be considered as a continuous data because it can't be counted in a definite number but can only be measured over a long period of time.
Soil type: This is Discrete because it can be counted. We can count the number of soil types we have in different areas.
Voting districts: This is Discrete because we can count the number of districts we have at any given time.
Temperature: This is Continuous because temperature cannot be counted but measured by the use of a thermometer.
Elevation: This continuous because it can't be counted as a number but measured.
Vegetation type: This is Discrete as we can count the number of places that have a particular vegetation type.

Graph the system of equations. Then determine whether the system has no solution, one solution, or infinitely many solutions. If the system has one solution, name it.y=-6x+6 y=-3x-3
Hey there! :)
Answer:
Has one solution.
(Graphed below)
Step-by-step explanation:
***The equations are graphed below, but this can also be solved algebraically.***
Set each equation equal to each other:
-6x + 6 = -3x - 3
Add 6x to both sides:
6 = 3x - 3
Add 3 to both sides:
9 = 3x
x = 3.
Plug in the value of x into an equation to solve for y:
y = -6(3) + 6
y = -18 + 6
y = -12.
The system of equations only has ONE solution at (3, -12).
On the graph, as well, the point of intersection is at (3, -12). This is the solution.
Find the gradient of the line 2y = 8x + 1
Find the y-intercept of the line 4y + 8x = -8
Bonus = Does the point (1 ,12) lie on the line y = 3x + 8 ? =
Does the point (-2 ,10) lie on the line y = 14 + 2x
Answer:
gradient=4 y intersept: B(0;-2) Point (1;12) doesn't lie on y=3x+8
(-2,10) lies on the line y=14+2x
Step-by-step explanation:
2y=8x+1 => divide both sides by 2=> y=4x+1/2 => gradient = 4
4y+8x= -8 => 4y= -8-8x => y=-2-2x . -2 - I indicated this number with the bold ( this ratio is the y coordinate of y- intersept. x coordinate=0
So the y-intersept is (0;-2)
We have a point (1;12) 1 is x coordinate of the point and 12 is y coordinate.
Put 1 and 12 instead x and y in the given formula. If we get the correct expression => the point lies on the line, if the expression is false=> doesn't lie on the line.
Now lets check !
12=3*1+8
12= 11 - false => the point (1;12) doesn't lie on y=3x+8
Similarly proceed: 10=14+2*(2)
10=14-4
10=10 - right ! Point (-2;10) lies on y=14+2x
