Step-by-step explanation:
Median: First write in ascending order. If number of data's is odd, median is the middle data.
If number of data's is even, then median = average of n/2th and (n+2)/2th term.
1) 1 , 3 , 5 , 5 , 6
Median = 5
2) 3,4,10,2,1
Ascending order: 1,2,3,4,10
Median = 3
3) 4, 5,7,11
Median = (5+7)/2 = 12/2 = 6
4) 1,1,2,6
Median = (1+2)/2 = 3/2 = 1.5
5) 2,2,3,3,,5,7
Median = 3+3/2 = 6/2 = 3
6)1,2,4,6,7,7
Median = (4+6)/2 = 10/2 = 5
7) 2,2,3,6,7,8
Median = (3+6)/2 = 9/2 = 4.5
8)1,2,3,14,17,18
Median = (3+14)/2 = 17/2 = 8.5
Mean= Sum of all the items÷ number of items
1)Mean = (1+2+3+2)÷4 = 8÷2 = 4
2)Mean=(4+3+2+4+2)÷5 = 15÷5 = 3
3)Mean = (5+4+6+1)÷4 = 16÷4 = 4
4)Mean = (2+5+1+4+7+5)÷6 = 24÷6 = 4
5)Mean =(10+11+9+12+8)÷5=50÷5 = 10
6)Mean = (1 + 2 + (-2)+1+(-2) )÷5 = -2÷5 = -0.4
7)Mean = (4+(-2)+3+(-3)+3)÷5 = 5÷5 = 1
8)Mean = (4+5.5+3+5.5)÷4=18÷4 = 4.5
Answer:
Median
1) 5
2) 3
3) 5+7=12/2=6
4)1+2=3/2=1.5
5)3+3=6/2=3
6) 4+6=10/2=5
7) 3+7=10/2=5
8)14+3=17/2=8.5
Mean
1) 2
2) 3
3)4
4)4
5) 10
6) 0
7) 1
8) 4.5
Step-by-step explanation:
Median is the middle number, make sure the list of in order from smallest to highest.
2) 1, 2, 3, 4, 10
if you have two numbers in the middle add them together then divide by 2
4) 1, 1, 2,6
5)2, 2, 3, 3, 5, 7
6) 1, 2, 4, 6, 7, 7
7)2, 2, 3, 7, 6,8
8)1, 2, 3, 14, 17, 18
Mean is when you add all the numbers together and divide by how many there are.
1) 1+3+2+2=8/4=2

Jeff, Lauren, and Sarah finished their meal, and their total for the three dinners before tax was $21.65. If the tax on their meal was 8.5%, how much was the total cost of their meal with tax? Round to the nearest hundreth.
Answers
Answer: The total cost of their meal with tax= $23.49
Step-by-step explanation:
Given: Cost of the three dinners before tax = $21.65
Tax = 8.5%
Tax amount = 8.5% of ( Cost of the three dinners before tax)
= (0.085) x 21.65 [0.085 = 8.5%]
= $1.84025 ≈ $ 1.84
The total cost of their meal with tax = Cost + Tax amount
= 21.65 + 1.84
= $23.49
Hence, the total cost of their meal with tax= $23.49

The diagram shows the graph of y = ax + b. Find the values of a and b *
Answers
Answer:
The values of a and b are:
a = 2b = 2Step-by-step explanation:
We know that the slope-intercept form of the line equation
y = ax+b
where
a is the slopeb is the y-interceptFrom the diagram of the line graph, we can fetch the two points
(0, 2)(-1, 0)Determining the slope between (0, 2) and (-1, 0)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:2\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)[/tex]
[tex]a=\frac{0-2}{-1-0}[/tex]
[tex]a=2[/tex]
Thus, the value of a = 2
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept b = 2
now substituting a = 2 and b = 2 in the slope-intercept form of the line equation
y = ax+b
y = 2x + 2 ∵ a = 2 , b = 2
Thus, the line of equation is:
y = 2x+2
now comparing with y = ax+b
Here:
a = 2
b = 2
Therefore, the values of a and b are:
a = 2b = 2Kobe, Amari, and DJ raised $125.45 for their football team. Kobe collected $24.55 more

If y varies directly with x and y = -3 when x = 6, find y when x = 14.
We know if y varies directly with x, we get the equation
y ∝ x
y = kx
k = y/x
where k is called the constant of variation.
we are given y = -3 when x = 6
so substitute y = -3 and x = 6 to determine 'k'
k = y/x
k = -3/6 = -1/2
Now we have to find y when x = 14
so substituting x = 14 and k = -1/2 to find y
y = kx
y = -1/2 × 14 = -7
Therefore, the value of y = -7 when x = 14
10) If y is directly proportional to x and y = 4 when x = 3, find x when y = -12.
we are given y = 4 when x = 3
so substitute y = 4 and x = 3 to determine 'k'
k = y/x
k = 4/3
Now we have to find x when y = -12
so substituting y = -12 and k = 4/3 to find x
y = kx
x = y/k
x = [-12] / [4/3] = [-12×3] / [4]
x = -36/4
x = -9
Therefore, the value of x = -9 when x = 3
11)
If y varies directly with x and y = -6 when x = 2, find the constant of variation.
We are given
y = -6
x = 2
so substitute y = -6 and x = 2 in the equation
k = y/x
k = -6/2
k = -3
Therefore, the value of the constant of variation will be:
k = -3Plllllllllllllllllllllllzzzzzzzzzzzz help me out I’m confused 25 points

Answer:
y = 7/4x
Step-by-step explanation:
All you have to do is find the slope by using the formula change in y divided by change in x of the two points. You can see that y goes up by 14 when x goes up by 8. This means that the slope is 14/8, or 7/4.
The equation would then be y = 7/4x

Answer:
The value of x = 12.
Step-by-step explanation:
We know that two angles are termed as supplementary when the sum of the measure of their angles is 180°.
We also know that a straight line angle measures 180°.
It is clear that the angles 72° and 9x° line on a straight line. Thus, the sum of the measure of their angles is 180°.
Therefore,
9x° + 72° = 180°
9x° = 180° - 72°
9x° = 108
divide both sides by 9
9x/9 = 108/9
x = 12
Therefore, the value of x = 12.

Tameka pilots a hot air balloon. She lowers the balloon
five times, going down an equal distance each time. In
all, Tameka lowers the balloon 75 m.
What integer represents the change in the hot air
balloon’s elevation each time Tameka lowers it?
What does this integer tell you?
Answers
Answer:
15 m
Step-by-step explanation:
Given that :
Change in distance is the same each time Ballon is lowered ;
Number of times Ballon is lowered = 5 times ;
Total change in distance = 75 m
Change in distance per time lowered equals ;
(Total change in elevation / Numbe rof times Ballon is lowered)
75m / 5
= 15 m
Hence, Ballon height changes by 15 m each time it is lowered.
The integer gives the lowering rate.
