A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
17p + 8p3 – 4 – 5(p3 – 2). Don't solve, I just need the simplest form
Answer:
26p+6
Step-by-step explanation:
17p+8p3-4-5(p3-2)
opening the bracket and multiply by -5
=17p+8p3-4-5p3+10
taking a common factor p
=p[17+(8×3)-(5×3)]+6
solve the simple mathematical calculation
=26p+6

Answer:
12) x= 29 ; (4+5x) = 149° ; (x+2) = 31°
15) x=29 ; (2x+1) = 59° ; (x+2) = 31°
16) x=17 ; (4+2x) = 38° ; (3x+1) = 52°
Step-by-step explanation:
So for each problem you follow the same steps.
1) See what the angles should measure up to. (#12 is 180°, and #15 & 16 is 90°
2) Write your equation. (I'm going to use #12 as an example). 4+5x+x+2=180
3) Simplify the equation. 6x+6=180
4) Solve the equation. x=29
5) Then replace each x with the 29, and solve.
6) To double-check the angles, add both angles together and they should be 180° (or whatever you decided you were solving for on step 1)

Step-by-step explanation:
The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?
160 ml
400 ml
1,600 ml
4,000 ml
Answer: 1,600 ml
Step-by-step explanation:
You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).
2,800 ml - 1,200 ml = 1,600 ml
I hope this helps :)
Answer: 1,600 mL
Step-by-step explanation:
1. convert the 1,200 mL to L, which is 1.2 L.
2. Subtract that value from 2.8 L, equaling 1.6 L
3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

Answer:
draw a line that makes a triangle and rectangle.
hypotenuse= 30
3k-4k-5k triangle
18-24-30
so the short part of triangle is 18 cm
10+10+18+24+30 equals 92
sorry for language I am not familiar with English
the perimeter of this shape is
24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm

what is the value of x?
Answer:
x=4
Step-by-step explanation:
8×4=12°
20×4=80°
17×4=64
12+80+64=180
8x+20x+17x=180
add all together,
20+8=28+17=45
180/45=4
your answer is 4
to check sub x for 4
8x4=32
20x4=80
17x4=68
68+32=100
100+80=180
X=4

Can someone help or like explain this to me? i’ve been confused on this for weeks!
In order to match these up, you first need to understand the basics and the definitions of each term. You also will need to know how to solve for each term. These are the definitions and how to solve for them:
Mean: This is the average of all the numbers. In order to find this, you need to add up all the numbers and divide the answer by the amount of numbers you added together.
Ex. 3, 8, 9, 3, 5, 7, 7 Mean is: (3+8+9+3+5+7+7) ÷ 7 = 6
Median: This is the middle number. In order to find it, you need to put all the numbers in numerical, or number, order. You then find which number is in the middle, and that is your median.
Ex. 3, 8, 9, 3, 5, 7, 7 Median: 3, 3, 5, 7, 7, 8, 9 median is 7 because it is the number in the middle.
Range: This is the difference between the smallest and biggest numbers. To find it, you subtract the smallest and biggest numbers.
Ex. 3, 8, 9, 3, 5, 7, 7 Range: 9 - 3 = 6. Range is 6.
Interquartile Range (IQR): This is the difference between Q3 and Q1. In order to find this, you need to first order the numbers in numerical order and find the median.
Ex. 3, 8, 9, 3, 5, 7, 7 IQR: 3, 3, 5, 7, 7, 8, 9
7 is the median, so we are now going to find the median of all the numbers before the 7 and all the numbers after the 7.
3, 3, 5 median(Q1) = 3 7, 8, 9 median(Q3) = 8
Now, we are going to subtract the Q1 by the Q3. Since 8 - 3 = 5, the IQR is 5.
Mean Absolute Deviation (MAD): This is the average distance between the mean of two separate data sets. In order to find this, you need to find the mean of each data set, then find the difference between them.
Ex. Data set A: 2, 2, 4, 4 Data set B: 1, 1, 6, 4
Mean: 3 Mean: 3
We are now going to figure out how far from the mean each point is.
Data set A: | 2-3 | + | 2-3 | + | 4-3 | + | 4-3 | ÷ 4(amount of numbers in data) = 1
Data set B: | 1-3 | + | 1-3 | + | 6-3 | + | 4-3 | ÷ 4(amount of numbers in data) = 2
MAD of data set A = 1 MAD of data set B = 2
Remember, in MAD, negative and positive don't matter. What matters is how far away from the mean each point is.
Now that you know what each of these terms are, you should be able to complete this worksheet. Please let me know if you need any more help or clarification. I hope this isn't too confusing. Good luck!
The approximate weights of the two animals are 5.12 x 102 lbs. and 6.8 x 102 lbs. Find the total weight of the two animals. Write the final answer in scientific notation with the correct number of significant digits. Can you please help me and stop deleting my question :(
these are the answers
1.2 x 103 lbs.
1.19 x 103 lbs.
11 x 102 lbs.
5.8 x 102 lb
Answer: Option A is the correct answer
Step-by-step explanation: I took the test and got it right
The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.
Given approximate weights of the two animals are as:
1. 5.12 x 10² lbs
2. 6.8 x 10² lbs
We need to find the total weight of the two animals.
Step 1: Add the weights together:
5.12 x 10² lbs + 6.8 x 10² lbs
Step 2: Perform the addition:
(5.12 + 6.8) x 10² lbs
11.92 x 10² lbs
Step 3: Express the result in scientific notation with the correct number of significant digits:
The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:
11.9 x 10² lbs
This matches option 2 from your provided answers:
2. 1.19 x 10³ lbs.
So, the correct answer is: 1.19 x 10³ lbs.
