Answer:
in a group of numbers (2,4,7,9,7,5,7,8,3)
The mean would be 5.2
The mode would be 7
The median would be 7
Explanation:
Say we have a group of numbers (2,4,7,9,7,5,7,8,3)
Lets start by finding the Median! *Remember, the median is the MIDDLE!
So, if the median is the middle, it would be 7.
Lets do the mode now. *Remember the mode is the one that happens the MOST!*
If we take a look at the numbers, we see that 7 occurs the most (it appears 3 times)
Our mode would be 7.
Lastly, lets do the mean. *You add and divide for the mean*
So, we start by adding all of the numbers together.
Basically, ( 2 + 4 + 7 + 9 + 7 + 5 + 7 + 8 + 3) you then get 52.
Next, we divide 52 by all the numbers that we added together (9)
And we get our mean: 5.2

A - Show that perimeters are the same.
B - Show that 16+9=25.
C - Show that 3+4=5.
D - Take the square root of 16.
Step-by-step explanation:
i think the answer is D but as i said . the base of so many right triangles sides are 3 ,4,5 so if you divide the biggest of them by 5 and divide the medium one by 4 and divide lowest one by 3 you should see a same number i think . but here you cant see
Fill in the blanks to explain how Harry can check whether his solution is correct
Answer is in bold
Harry can first substitute 30 for t. He can then multiply [tex]\frac{1}{3}[/tex] by 30 to get a product of 10. Since 15 is equal to 30 × 1/2, Harry's solution is not correct.

1. x = 31
2x + x - 3 = 90
3x - 3 = 90
3x - 3 + 3 = 90 + 3
3x + 93
3x / 3 = 93 / 3
x = 31
2.
NPO =
90 - (x - 3) = 2x
90 - (31 - 3) = 2 * 31
90 - (28) = 62
62 = 62
KPN =
90 - 62 = KPN
28 = KPN

(a) 34 is 85% of what number?
(b) What is 15% of 80?
Answer:
A. 40. B.12
Step-by-step explanation:
40/34=.85
80*.15=12
Answer:
Part A: 40
Part B: 12
Step-by-step explanation:
Given the following question:
Part A:
34 is 85% of what number?
[tex]\frac{85\times40}{100} =85\times40=3400\div100=34[/tex]
85% of 40 is 34.
Part B:
15% of 80
[tex]\frac{15\times80}{100} =15\times80=1200\div100=12[/tex]
15% of 80 is 12.
Hope this helps.

24x - 17 x ≥ 13x +15
Pls solve and add the equation if you can thank you :)
Given :-
[tex]24x - 17 x ≥ 13x +15[/tex]
Solving it,
[tex](24 - 17)x \geqslant 13x + 15[/tex]
[tex] = > 7x \geqslant 13x + 15[/tex]
[tex] = > 7x - 13x \geqslant 15[/tex]
[tex] = > (7 - 13) x \geqslant 15[/tex]
[tex] = > - 6x \geqslant 15[/tex]
[tex] = > x \leqslant - \frac{15}{6}[/tex]
By reducing to lowest terms, we get,
[tex]x \leqslant - \frac{5}{2}[/tex]
So, Value of x is [tex] - \frac{5}{2}[/tex]

A vintage wheel needs to be banded with an iron strip. If the wheel’s radius is 11 inches, how long must the iron strip be to go all the way around the wheel? Complete the steps below to answer the question.
Answer:
Step-by-step explanation:
first lets find the circumference of the wheel:
[tex]C=\pi *d[/tex]
we have to find the diameter out of the radius:
[tex]d=r*2[/tex]
because the radius is half of the diameter, intrhis case i have to findf the diameter so i do multiply it with 2:
[tex]r=11\\d=??\\d=11*2\\d=22[/tex]
we found the diameter now we are going to find the circumference :
[tex]C=\pi *d\\C=\ 3.14*22\\C= 69.08[/tex]
Another way (easier)to find the circumference is:
[tex]C=2\pi *r\\C=2(3.14)*11\\C=69.08[/tex]
At the end it will hav ethe same answer.
Answer:
69.08 inches
Step-by-step explanation:
substitute the values of r (11 inches) and pi (3.14) in the formula c = 2πr to find c:
c = 2 × 3.14 × 11 inches
c = 69.08 inches.
the circumference of the wheel is about 69.08 inches.

PLEASE HELP!!!!!!
Answer:
slope is -3
y-intercept is 3
Step-by-step explanation:
Answer:
y-intercept: 3
Slope: -3
Step-by-step explanation:
y-intercept
To find the y-intercept, see what point on the y-axis (vertical bold line on the graph) the line passes through.
Slope
To find slope, find 2 points (from left to right) on the line and and put the height difference over the width difference in a fraction (simplify if possible). At points (0,3) and (1,0) there is a height drop of 3 (so -3) and a width of 1 and [tex]\frac{-3}{1}[/tex] gives you a slope of -3.
evaluate 36 / x + 9 when x equals 3
Answer:
3.Step-by-step explanation:
Given equation:
36 ÷ x + 9Given variables:
x = 3.Solve:
36 ÷ x + 9= 36 ÷ 3 + 9= 36 ÷ 12= 3.7b - 15 = 5b - 3
5c + 16.5 = 13.5 + 10c
20 + 3y = 10 - 2y
17 + 4h + 2 = 1 - 5h
1. 7b-15=5b-3
move 5b and 15
7b - 5b = -3 + 15
2b=12
b=6
2. 5c + 16.5 = 13.5 + 10c
5c=3
c=3/5
3. 20 + 3y = 10 - 2y
-5y=10
y=-2
4. 17 + 4h + 2 = 1 - 5h
19 + 4h = 1 - 5h
-9h=18
h=-2
Miles owes one of his friends $8. If he borrows $15 from his parents, which of the following expressions could be used to find how much money he owes?
Can you please help me
Answer:
x= 55
Step-by-step explanation:
Before we begin, the question tells us that angle JKL is a right angle. A right angle means the angle is 90 degrees. It tells us that one of the angle is 35 degrees and another is x. Since they make up a right angle, 35 plus x should equal to 90. To find x, subtract 35 from 90 and you get 55.

1/2 (6x - 2) - (2x + 1)
He does the following:
1/2 (6x - 2) - (2x + 1)
3x - 1 - x + 1/2 =
3x + x - 1 + 1/2 =
4x - 1/2
Is this correct? If not, show the correct procedure and explain where Thomas made his mistake.
Answer:
Thomas is not correct, x-2 is the correct answer
Step-by-step explanation:
Thomas made his mistake by multiplying the 1/2 by both (6x-2) and -(2x+1). Thomas should have multiplied the 1/2 by just the (6x-2).
Correct procedure:
1/2 (6x-2)-(2x+1)
(3x-1)-(2x+1)
3x-1-2x-1
x-2
