Lily works at a department store and creates a survey to determine how sales affect their business. Choose the survey method(s) that would result in a valid random sample of the community.
The survey methods that would result in a valid random sample of the community include:
Simple random samplingStratified random samplingSystematic samplingCluster samplingOption E. All of the above is correct.
Which survey method leads to a random sample ?Simple random sampling involves selecting a random sample of participants from a larger population using a random number generator or a random sampling software. This method ensures that every member of the population has an equal chance of being selected.
Stratified random sampling involves dividing the population into smaller groups or strata based on certain characteristics, such as age, gender, income, etc. A random sample is then selected from each stratum. This method is useful when the population is heterogeneous and you want to ensure that the sample is representative of the entire population.
Systematic sampling involves selecting participants at regular intervals from a list of the population. This method is useful when the population is ordered, such as a list of customers.
Cluster sampling involves selecting a random sample of clusters or groups from the population, and then sampling individuals within those clusters. This method is useful when the population is geographically dispersed or it's difficult to obtain a complete list of the population. So Lily can use any of these survey methods to come up with a sample of the community.

and the point is (-3, -2). Is this line vertical or horizontal?
HINT: You can find the equation of the line in slope-intercept form by:
1. Use point-slope form, then solve for y.
OR
2. Use y=mx+b: Plug in your point and your slope to find b; then write in
slope-intercept form.
So, The line is a horizontal one, and the equation is y = -2 of a line in slope-intercept form if the slope is 0 and the point is (-3, -2).
Define slope.In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. Slope is computed mathematically as "rise over run" (change in y divided by change in x).
Define line's steepness and direction.Positive slope lines lean to the right, and they become steeper as the slope increases. A line with a negative slope slopes left, and the slope's magnitude determines how steep the line is. Since there is no slope on a horizontal line, it has a slope of zero.
The slope of the line is 0, which means the line is horizontal.
The point-slope form of the equation of a line is: y - y1 = m(x - x1)
With the point (-3, -2) and the slope of 0, we have:
y - (-2) = 0(x - (-3))
y = -2
The slope-intercept form of the equation of a line is: y = mx + b
The y-intercept of the line is -2, so the equation of the line in slope-intercept form is: y = 0x + (-2)
The line is a horizontal one and it's equation is y = -2

A jar contains 4 white chips, 5 purple chips, and 1 black chip. Chips are selected randomly one at a time, and are not replaced.
P(3 whites)
A: 6/43
B: 2/39
C: 5/41
D: 1/36
Answer:1/30 is the correct answer
Step-by-step explanation:

Use a diagram at right to answer the following questions. Parts a-f only
Part (a)
You are correct.Line p can be named as "line RV" or "line AV" since these points are on line p. The order of the lettering doesn't matter.
==============================================
Part (b)
Pick any three non-collinear points in plane W. In other words, we pick three points in the plane that do not fall on the same line.
The following points are located in this plane: S, R, Q, T, Z
Here are some possible names:
Plane STRPlane SZQPlane QTZSomething like "Plane SRQ" isn't valid since those three points are on the same line. Infinitely many planes pass through these three points.
The ordering of the letters doesn't matter. For instance, "plane STR" is the same as "plane RTS".
==============================================
Part (c)
You are correct.As mentioned in part (b) earlier, these points fall on the same straight line. Hence they are considered collinear.
==============================================
Part (d)
Pick any four points that reside in plane W.
You have this list to choose from: S, R, Q, T, Z
Let's say we pick the first four to write S, R, Q, T as the answer
These points are coplanar because they reside in the same plane. The non-coplanar points are A and V since they are outside the plane W.
==============================================
Part (e)
Technically there aren't any line segments shown. Instead the diagram shows lines. But we can focus on a subset of a particular line to form a segment.
For instance, line p has points A and V on it. Therefore we can form segment AV
The symbolic notation for this would be to write [tex]\overline{\text{AV}}[/tex]
==============================================
Part (f)
Answer: Ray RA and Ray RVReason:
A line is composed of opposite rays. For instance, a vertical line consists of a ray pointing north and a ray pointing south. The two rays are glued together at the endpoints.
For line p, we can glue together ray RA and ray RV to form this line. Unlike the other naming conventions, the order does matter. Something like "ray RV" is not the same as "ray VR". The first letter tells us the endpoint that doesn't go on forever.

A rainstorm in Portland, Oregon, has wiped out the electricity in about 10% of the households in the city. A management team in Portland has a big meeting tomorrow, and all 6 members of the team are hard at work in their separate households, preparing their presentations. What is the probability that none of them has lost electricity in his/her household? Assume that their locations are spread out so that loss of electricity is independent among their households.
Answer:
The probability that a given household has lost electricity is 10%, or 0.1. So the probability that a given household has not lost electricity is 1 - 0.1 = 0.9.
Since the loss of electricity is independent among the households of the management team, we can find the probability that none of them has lost electricity by multiplying the probability of no loss in any one household (0.9) by itself 6 times, since there are 6 members of the team:
0.9 * 0.9 * 0.9 * 0.9 * 0.9 * 0.9 = 0.54
So the probability that none of the management team members has lost electricity in his or her household is 54%.

The second function 100(.1593)^t decays faster than the first function 100(.2661)^t.
How to determine the function that decay fastestTo find which function decays the fastest, we need to compare the decay rates of the two functions.
The decay rate of a function is determined by the exponent in the function. In this case, the exponent is t.
The smaller the exponent, the faster the decay rate.
So, in the first function 100(.2661)^t, the exponent is t.
In the second function 100(.1593)^t, the exponent is also t.
We can compare the decay rates of the two functions by comparing the values of the bases, .2661 and .1593.
The base of a function represents the rate of decay, the smaller the base the faster the decay rate.

principles of dalton atomic theory
Dalton's Atomic Theory (1804)
From his experiments and observations, as well as the work of peers of his time, Dalton proposed a new theory of the atom. This later became known as Dalton's atomic theory. The general tenets of this theory were as follows:
All matter is composed of extremely small particles called atoms.Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.Atoms cannot be subdivided, created, or destroyed.Atoms of different elements can combine in simple whole-number ratios to form chemical compounds.In chemical reactions, atoms are combined, separated, or rearranged.According to Dalton’s atomic theory, all matter, whether an element, a compound, or a mixture is composed of small particles called atoms.
Dalton based his theory on two laws: the law of conservation of mass and the law of constant composition.

There is 25 pounds of dog food in a bag. There are approximately 2.2 kilograms in 1 pound. PLEASE HELP ME !! THANK YOU SMM!!
Which statement is true?
A. There is approximately 55 kilograms of dog food in the bag, because 1/2.2 = 55/22.
B. There is approximately 11.36 kilograms of dog food in the bag, because 1/2.2 = 25/11.36
C. There is approximately 55 kilograms of dog food in the bag, because 1/2.2 = 25/11.36
D. There is approximately 11.36 kilograms of dog food in the bag, because 1/2.2 = 11.36/25
The statement that is true is D. There is approximately 11.36 kilograms of dog food in the bag, because 1/2.2 = 11.36/25
To convert between pounds and kilograms, we use the conversion factor of 1 pound = 2.2 kilograms. This means that 1 pound is equal to 2.2 kilograms, and 2 pounds is equal to 4.4 kilograms, and so on.
In this case, we are given that there is 25 pounds of dog food in a bag, and we want to convert this to kilograms. To do this, we can multiply 25 pounds by the conversion factor of 1 pound = 2.2 kilograms.
25 pounds * (1 kilogram / 2.2 pounds) = 25/2.2 = 11.3636363636 kg.
So, there is approximately 11.36 kilograms of dog food in the bag.
The other options are incorrect. In option A, 1/2.2= 55/22 which is not equal to 25 pounds and the same case in option C. In option B the calculation is not correct as well because 1/2.2 = 25/11.36 doesn't make sense.
Therefore, the only true statement is D. There is approximately 11.36 kilograms of dog food in the bag, because 1/2.2 = 11.36/25

Find the perimeter of triangle ABC. Round your answer to two decimal places.
(9,-2) (5,1) (9,-3)
Answer: To find the perimeter of a triangle, we need to add the length of all three sides of the triangle.
To find the length of each side, we can use the distance formula which is the square root of (x2-x1)^2 + (y2-y1)^2.
The distance between point A (9,-2) and point B (5,1) is: √((9-5)^2 + (-2-1)^2) = √16 + 9 = √25 = 5.
The distance between point B (5,1) and point C (9,-3) is: √((9-5)^2 + (-3-1)^2) = √16 + 16 = √32 = 5.66.
The distance between point C (9,-3) and point A (9,-2) is: √((9-9)^2 + (-3- -2)^2) = √1 + 1 = √2 = 1.41
The perimeter is the sum of the length of all three sides:
Perimeter = 5 + 5.66 + 1.41 = 12.07
Round the answer to two decimal places, the perimeter of the triangle is 12.07.

Use the shell method to find the volume of the solid generated by revolving the regions bounded by the curves and lines about the y-axis.
y=x2, y=5−4x, x=0 for x≥0
The volume of the solid generated by revolving the regions bounded by the curves and lines about the y-axis is 8.90 unit³.
How do you find the volume of a solid?Since the region is the one for then the intersection we are interested on is x=1 as it can also be seen in the graph.
Where h(x) is the height of the shell which here is the distance between the parabola and the line, so (since the line is on the top we subtract from it the parabola
Notice the limits of the integral are the x-axis (x=0) and the intersection of the parabola and the line that we found before (x=1)
We want the volume generated when the area bounded by the curves :
v = x2 v = 8 —7x , and
x = 0 for x > 0 is revolved about the y axis using the cylindrical shell method .
The intersection of y = x2 and y = 8 —7x is :
y= x2 = 8 — 7x x2 + 7x —8 = 0
(x + 8)(x — 1) = 0 x = —8 or
x = 1 .
We thus have for x > 0 the two curves intersect at x = 1 and y = 12 = 1 .
The limits for integration are --- 0 <x < 1 .
The upper curve is --- y2 = 8 —7x ,
and the lower curve is --- yi = x2 .
The height of the shell is --- h = y2 -yi = 8 —7x — x2 •
The radius of the shell is --- R = x •
[tex]$$The surface area of the shell is :$$A=2 \pi \mathrm{Rh}=2 \pi x\left(8-7 x-x^2\right)=2 \pi\left(8 x-7 x^2-x^3\right) .$$The differential of volume which is the cylindrical shell is :$$\mathrm{dv}=\mathrm{Adx}=2 \pi\left(8 x-7 x^2-x^3\right) \mathrm{dx}$$[/tex]

Anthony wants to plant a garden but is worried that rabbits will eat his crop so he decides to put up a fence around his plot. one side of the garden will be adjacent to a barn which is 22 feet long. he wants to be 176 square feet
Answer:
Step-by-step explanation:
.
The best way for Anthony to plan his garden is to create a rectangular plot. He can use the side of the barn as one side of the rectangle, and then measure out the other three sides. The total length of the three sides will be 176 feet. He can divide this into two sides that are 88 feet long and two sides that are 44 feet long. This will give him a rectangular plot that is 176 square feet.
Once Anthony has the dimensions of the plot, he can build a fence around it to protect it from rabbits. He can use a variety of materials such as wood, wire, or plastic mesh to build the fence. The fence should be at least four feet tall and buried at least six inches deep to be effective. If he chooses to use wire, he should use thick, galvanized wire to make sure that the rabbits cannot chew through it.
Once the fence is in place, Anthony can begin planting his garden. He should also consider adding a layer of mulch or straw around the outside of the fence to discourage the rabbits from digging underneath it. With the right planning and protection, Anthony should be able to enjoy a successful garden.

Answer: Lena walks 63 miles in 10 days.
Step-by-step explanation:
To find out how many miles Lena walks in 10 days, you need to add up all the distances she walks each day.
From the information provided, it seems that the distances walked each day are:
23 miles, 11 miles, 10 miles, 19 miles and the remaining days is not given.
So, to find the total miles Lena walks in 10 days, you would add up the distances walked each day:
23 + 11 + 10 + 19 = 63 miles
So, Lena walks 63 miles in 10 days.
The total miles in 10 days will bed 14 miles. The closest option is OD, which is 19 miles.
How to calculate the distance covered?To find the total distance Lena walks in 10 days, we need to add up all the distances on the line plot:
Starting from day 1, we can count the distances and add them up:
On day 1, Lena walks 1 mile
On day 2, Lena walks 2 miles
On day 3, Lena walks 1 mile
On day 4, Lena walks 1 mile
On day 5, Lena walks 2 miles
On day 6, Lena walks 1 mile
On day 7, Lena walks 2 miles
On day 8, Lena walks 1 mile
On day 9, Lena walks 1 mile
On day 10, Lena walks 2 miles
Adding up all these distances, we get:
1 + 2 + 1 + 1 + 2 + 1 + 2 + 1 + 1 + 2 = 14
Therefore, Lena walks a total of 14 miles in 10 days.
Thus, the closest option is OD, which is 19 miles.

Cornell drives 3 times the hours that Deborah does. Cornell and Deborah drive for a total of 8 hours. How long did each person drive?
Answer: Let's call the number of hours Deborah drives "d" and the number of hours Cornell drives "c".
We know that:
c = 3d (because Cornell drives 3 times the hours that Deborah does)
and
c + d = 8 (because they drive for a total of 8 hours)
We can use the first equation to substitute the value of c in the second equation:
3d + d = 8
4d = 8
d = 2
So Deborah drives 2 hours.
Now we can use the first equation to find the number of hours Cornell drives:
c = 3d
c = 3(2) = 6
So Cornell drives 6 hours.

true or false? a percentage can be converted to a decimal number by multiplying the percentage by 100, then using that result in a calculation
Answer:
False
Step-by-step explanation:
False. That is how a decimal is converted to a percent.
A percent is converted to a decimal by taking the percent and dividing by 100%
For example:
56% is converted to a decimal by dividing by 100%
56%/100% The percents cancel out and when you divide by 100, you move the decimal two places to the left. .65
Suppose f left parenthesis x right parenthesis equals x squared plus 4 and g left parenthesis x right parenthesis equals 2 x plus 1.
Find the value of f(-2)g(-2).

Answer:
C) -24
Step-by-step explanation:
We have two functions here:
[tex]f(x) = x^{2} + 4[/tex]
and
[tex]g(x) = 2x + 1[/tex]
Now, both of these functions will be multiplied together after they are figured out (since they are next to each other), and they will have -2 replace x. For function f, we get:
[tex]-2^{2} + 4[/tex]
For function g, we get:
[tex]2 * -2 + 1[/tex]
Simplifying these two gives us:
[tex](4 + 4) * (1 - 4)[/tex]
Simplifying further gives us:
[tex]8 * -3 = -24[/tex]
So, the value of f(-2)g(-2) is C) -24.
Hope this helped!
Answer:
B) -24
Step-by-step explanation:
Given functions:
[tex]\begin{cases}f(x)=x^2+4\\g(x)=2x+1\end{cases}[/tex]
To find f(-2)g(-2), substitute x = -2 into both functions and multiply them:
[tex]\begin{aligned}\implies f(-2)g(-2)&=\left((-2)^2+4\right)\left(2(-2)+1\right)\\&=\left(4+4\right)\left(-4+1\right)\\&=8 \cdot -3\\&=-24\end{aligned}[/tex]
