Answer:
Median. Explanation to each part below.
Step-by-step explanation:
a) Starting with calculating the mean, which is all the values added divided by the number of values (in this case he has 6 scores total).
[tex]mean/average=\frac{81+87+93+89+61+81}{6} =\frac{492}{6} = 82[/tex]
b) To find the median, arrange all the test scores in increasing order and find the middle/median value. We have 6 scores, so we will have 2 middle scores. If we had 7 scores, we would find only 1 score in the middle which would be the median. We will have to find the average of the two scores.
[tex]61,81,81,87,89,93[/tex]
The middle values will be 81 and 87 so find the average of those 2 scores.
[tex]Median: \frac{81+87}{2} =\frac{168}{2} =84[/tex]
c) The mode is the score which occurs the most. In this case, Jack has 2 scores that are 81, which is his mode.
d) The measure that would make his performance sound good would be the median. The mode and mean are below the score of 84 that he gets for the median. He would want to flaunt this measure to show he performs well.

Algebra basic fractions 5:

Answer:
1) x + 4 = 11
Subtract 4 on both sides, to get x = 7 .
2) x + 3 = 24
Subtract 3 on both sides, to get x = 21 .
3) 4x = 12
Divide 4 on both sides, to get x = 3 .
4) 5x + 3 = 33
First subtract 3 on both sides to get
5x = 30, now divide 5 on both sides, to
get x = 6 .
5) 8x + 5 = 3x + 20
First subtract 5 from 20 in order to
move it, now you have 8x = 3x + 15 .
Next subtract 3x from 8x in order to
move it, now you have 5x = 15 . Lastly
divide 5 on both sides, to get x = 3 .
1) 1/2 x = 4
Multiply both sides by 2, to get 1x = 8,
or x = 8 .
2) 4/3 x = 4
Multiply both sides by 3, to get 4x = 12 .
Next divide 4 on both sides to get
x = 3 .
3) 2x + (-4) = 8
Add 4 on both sides, to get 2x = 12 .
Next divide 2 on both sides to get
x = 6 .
4) 1/3 x + 1/2 x = 20
First multiply the denominators to get a
common denominator of 6 and then
add 3 and 2, to get the numerator. Now
you have 5/6 x = 20 . Next multiply 6
on both sides to get 5x = 120 . Lastly
divide 5 on both sides to get x = 24 .
5) 1/3 x = 1/5 x + 10
First multiply the denominator to get a
common denominator of 15 and then
subtract 3 from 5 to get the numerator.
Now you have 2/15 x = 10 . Next
multiply 15 on both sides to get
2x = 150. Lastly divide 2 on both sides
to get x = 75 .

Arrange 13.25 kg, 14560 g, 13.6 kg, 12000 g in descending order ,
Write the following decimals as fractions. Reduce the fractions to lowest
form.
a) 3.6 b) 12.5
i hope u also consider explaining
thank you all .
Answer:
Descending order:
14560g
13.6kg
13.25kg
12000g
a.) [tex]\frac{18}{5}[/tex]
b.) [tex]\frac{25}{2}[/tex]
Step-by-step explanation:
To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.
If we were to put everything into g:
14560g
13600g
13250g
12000g
See how they are still in the correct order?
If we were to put everything into kg:
14.56kg
13.6kg
13.25kg
12kg
Still in descending order!
___________________
Now to find out how to put the decimals into fractions:
Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)
Following this we get:
36
125
Now divide by the same factor (10), we can't change the value of the number, just the way they look!
[tex]\frac{36}{100}[/tex]
[tex]\frac{125}{10}[/tex]
All that's left is it reduce!
[tex]\frac{18}{5}[/tex]
[tex]\frac{25}{2}[/tex]
And as you can see, we are back to the number I had put in the solution!

Find g(f(x)), given f(x)=3x2−x+1,g(x)=2x
Answer:
6x²-2x+2
Step-by-step explanation:
For g(f(x)), we have to first do f(x), and then substitute it into the "x" in g(x)
So, f(x) = 3x²-x+1
We need to substitute the "x" in g(x) with this entire thing
So, g(x) = 2x
When we substitute f(x) into it, it instead becomes 2(3x²-x+1)
Next, we have to expand the brackets, and doing so gives us the following:
6x²-2x+2
So that becomes our final answer!

Step-by-step explanation:
The function g(x) is a transformation of the quadratic parent function, f(x)=x2. What function is g(x)?
Answer:
D.
Step-by-step explanation:
Your graph of f(x)= [tex]x^2[/tex] is the parent function. What you need to know for this graph what the stretch or compression is and what the flip is. When you flip somehting over the x-axis, which is g(x), your [tex]x^2[/tex] is negative. Also, since your graph gets skinnier, the number before the x would be a whole number, with no fractions. The only answer that fulfills this is answer choice D.

The ordinate of a point is twice its abscissa . If its distance from the point (4,3) is √10 units ,then the coordinates of the point are ?
Answer:
(1 , 2) and (3 , 6)
Step-by-step explanation:
the point P : (x , y) -> (x , 2x) ... ordinate of P point is twice its abscissa, y = 2x
√10 = √(x-4)² + (2x-3)²
5x² - 20x + 25 = 10
x² - 4x + 3 = 0
(x-1)(x-3) = 0
x = 1 or x = 3
y = 2 or y = 6

Select the correct line. Which line is perpendicular to AB
Answer:
line 1
Step-by-step explanation:
perpendicular is the opposite so therefore line 1 is the answer
From the given figure, line AB perpendicular to line 1.
We need to check which line is perpendicular to AB.
What are perpendicular lines?In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.
From the given figure we can see that line AB perpendicular to line 1.
The line AB perpendicular to line 1, intersect each other and made an angles 90°.
Therefore, from the given figure, line AB perpendicular to line 1.
