why are conclusions about a population more likely to be correct when they are based on random samples that are not random.

Answers

Answer 1

Answer:

1) Sampling error leads to mostly variability, nonsampling errors lead to bias. 2) Because of nonsampling error, a sample is often more accurate than a CENSUS.

Step-by-step explanation:

Answer 2
Conclusion’s about a population are more likely to be correct because there is less variability then there is in a random sample

If you had a set of numerical data and you wanted to see what was typical for that set of data, what type of graph should you use? bar graph pictograph line plot line graph. I searched and did not find it

Answers

Hey there! :)

(1) I would say bar graph because on bar graphs, you can separate all the data into different bars and compare all the different data.

(2) For finding mean, you have to add all the numbers and divide by how many numbers there are.

0 + 1 + 2 + 3 + 4 + 5 + 6 = 21

There are 7 numbers.

21 ÷ 7 = 3

The mean is 3

It is given that: all the three cylinders are identical, means their radii and heights are equal.

Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

First Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 2.

Second Question: Screenshot the following image and attach a photo after you dilate by a scale factor of 1/3.

Please help! If you help with this please do my other questions!! (They are very similar!)

Answers

Answer: See in the explanation, screenshot attached

Step-by-step explanation:

SQUARE QRTS

Step 1: Label all of  the coordinates

Step 2: Find the coordinates of the points

Q: (-2, 1)

R: (2, 1)

T: (-2, -2)

S: (2, -2)

Step 3: Know what it means to dilate

To dilate is to make a shape bigger or smaller. For example, when it says to dilate by a scale factor of 2, you multiply each coordinate by 2 to get coordinate pairs that are twice the original amount (in this case you make it bigger). However, if it says to dilate by a scale factor of a fraction, for example 1/2, you'd multiply the coordinates by 1/2 and hence make it smaller (1/2 its size).

Step 4: Dilate by a scale factor of 2--multiply by 2

*x stands for the x coordinate, and y stands for the y coordinate*

Q: -2, 1

x: -2x2= -4

y: 1x2= 2

[Dilated] Q: -4, 2

R: 2, 1

x :2x2= 4

y: 1x2= 2

[Dilated] R: 4, 2

T: -2, -2

x: -2x2= -4

y: -2x2=-4

[Dilated] T: -4, -4

S: 2, -2

x: 2x2= 4

y: -2x2= -4

[Dilated] S: 4, -4

Step 5: Plot the new pairs

(See screenshot)

SQUARE ABCD

Step 1: Label all the coordinates

Step 2: Find the coordinate pairs of the points

A: -3, 3

B: 3, 3

C: 3, -3

D: -3, -3

Step 3: Remember what it means to dilate

(See 1st explanation)

Step 4: Dilate by a scale factor of 1/3

**Since 1/3 is a fraction, we are making the square smaller, or making it ⅓ of its original size. You will see that the numbers of the coordinates get smaller once you dilate them.**

A: -3, 3

x: -3x1/3= -1

y: 3x1/3= 1

[Dilated] A: -1, 1

B: 3, 3

x: 3x1/3 = 1

y: 3x1/3= 1

[Dilated] B; 1, 1

C: 3, -3

x: 3x1/3= 1

y: -3x1/3= -1

[Dilated] C: 1, -1

D: -3, -3

x: -3x1/3= -1

y: -3x1/3= -1

[Dilated] D: -1, -1

Step 5: Plot the new pairs

(see screenshot)

Hope this helps :))

The experimental probability of the event is
Choose... 20, 30, or 32

Hey need some help, I don't really under stand, I see that every one of them can be divided by 8 though. Thanks for the help!

Answers

Answer:

the answer should be 1:8 or 1/8 either way it tells you in the scale factor and in the fraction so remember we need to divide first the sculpture then the model since the sculpture has highest numbers and then the mode so as shown below here are the results of each one.

56/7=8

40/5=8

72/9=8

so the scale factor should be 1:8 since 8 units is 8 units in real life since and the fraction should be 1/8 so hopefully those are the correct answer and tell me if i am wrong so i can correct the answer to make it better.
