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.

Find the value of x [tex]\frac{3}{2}x+5=14.[/tex]
Answer:
x=6
Step-by-step explanation:
bc 3/2 x 6 = 18/2 = 9 9+5=14
Answer: 6
Step-by-step explanation:
(3/2)x + 5 = 14
(3/2)x = 14 - 5
(3/2)x = 9
x = 9 / (3/2)
x = 9*2/3
x = 18/3
x = 6
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
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
Hope this helps :)

Answer:
[tex]V_{composite\: figure} =678.24\: in^3[/tex]
Step-by-step explanation:
For a single cylinder:radius (r) = 3 in (Given)height (h) = 8 in (Given)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.[tex]\implies V_{composite\: figure} =3(\pi r^2 h)[/tex][tex]\implies V_{composite\: figure} =3(3.14\times (3)^2 \times 8)[/tex][tex]\implies V_{composite\: figure} =3(226.08)[/tex][tex]\implies V_{composite\: figure} =678.24\: in^3[/tex]Answer:
Step-by-step explanation:
For a single cylinder:
radius (r) = 3 in (Given)
height (h) = 8 in (Given)
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.

The dot plots below show the scores for a group of students for two rounds of a quiz:
Which of the following inferences can be made using the dot plots?
A. The range of each round is the same.
B. There is no overlap between the data.
C. Round 1 scores were higher than round 2 scores.
D. Round 2 scores were lower than round 1 scores.
Answer: A. The range of each round is the same.
Step-by-step explanation:
Below shows the total score for both rounds. As you can see the totals for both rounds are very close so their range is most likely the same.
Round 1
(2 x 2) + (3 x 3) + (4 x 2) + 5 = 26
4 9 8
Round 2
(3 x 2) + (4 x 3) + (5 x 2) + 2 = 30
6 12 10
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!)
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 :))
Also I worked pretty hard on this so brainiest would be appreciated :D
A figure shows a triangle drawn inside a trapezoid. The area of the triangle is 445 in², and the area of the trapezoid is 2225 in². A point on the figure is randomly selected, and its location is recorded.
After 150 trials, the randomly selected point was in the triangle 48 times.
How does the experimental probability of a randomly selected point being in the triangle compare to the theoretical probability of the event?
The experimental probability of the event is
Choose... 20, 30, or 32
and the theoretical probability of the event is
Choose...20, 30, or 32
Therefore, the experimental probability is
Choose... equal to, greater than, or less than.
the theoretical probability.
1) 70%
2) 62.5
3) GREATER THAN
Answer:
32%
20%
greater than
Step-by-step explanation:
The experimental probability of the event is 32% and the theoretical probability of the event is 20%. Therefore, the experimental probability is greater than the theoretical probability.

Not my work, but it was expert verified if that help! Have a lovely day!
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!
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.

Patricio deposits $500 in a savings account that pays 1.5% simple interest. He does not withdraw any money from the account, and he makes no other deposits.
How much money does Patricio have in the savings account after 5 yr?
Answer:
$537.50
Step-by-step explanation:
Initial Deposit = $500at a 1.5% interestSo . .
500.00 ×1.5 =7.5Then . .
7.5 is for 1 year so
7.5 × 5 = 37.5Then just add 37.50 to 500
Final outcome = $537.50Answer: He will have 3750 in 5 years.
Step-by-step explanation: You need to do 500x1.5x5. 500 dollars is the amount in the account. 1.5 is the interest. 5 is the amount of years.

Find the approximate volume of a cylinder that has a diameter of 16 in. and a height of 10 in. Use 3.14 for π.
You may use your formula sheet and a calculator.
Question 4 options:
502.4 in³
2009.6 in³
251.2 in³
8038.4 in³
The answer is option C( 2009.6)
[tex] {in}^{3} [/tex]
Answer:
2009.6 in^3
Step-by-step explanation:
The formula for finding the volume of a cylinder is:
V=Bh
B= area of the base
h= height
Diameter= 16 radius= 16/2=8
V= (3.14*8^2)10
V= (3.14*64)10
V= 200.96(10)
V= 2009.6 in^3
