Answer:
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

Answers
Answer: the last one
Step-by-step explanation:
um so the set begins with 40 and ends with 100 (look at that on the number line)
and so the median is essentially that middle line in the box, which is around 80
i assume yk how to calculate medians so I calculated the median of the first and the last answer
the first one was like 70, and the last one was like 78.9 which is close enough to 80
so i think its the last one
Answer:
It is answer number four.
Step-by-step explanation:
40 and 100 represent the outliers so both numbers must be included.
80 must also be included as it is the mean or average test grade.

Answers
Answer: 39
Step-by-step explanation:
D. 39
Explanation:you use the pythagorean theorem which is [tex]a^{2}+b^{2} = c^{2}[/tex]
if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).
so your equation will look like this:
[tex]15^{2} + 36^{2} =c^{2}[/tex]
Solving For The Length Of BC1. [tex]15^{2} + 36^{2} =c^{2}.[/tex] (solve for [tex]15^{2} and 36 ^{2}[/tex])
2. C= 225+1296 (add)
3. C= 1521 (find the square root of 1521)
4. [tex]\sqrt{1521} = 39[/tex]
Therefore, 39 is your answer

Answer:
Step-by-step explanation:
Given: i. AB||DE

Prove: ΔABC≅ΔDEC
From the two triangles, it can be observed that;
m<BAC≅m<EDC (alternate angles)
m<ABC≅m<DEC (alternate angles)
m<BCA≅m<ECD (vertically opposite angles)
m<BAC + m<ABC + m<BCA = m<EDC + m<DEC + m<ECD = [tex]180^{o}[/tex] (sum of angles in a triangle)
Since the three angles of the triangles are congruent respectively, then;
ΔABC≅ΔDEC (AAA congruence property)

What is the equation of the line that passes through the points 1/2/3 and (-1,-1
a.y=-6x+5
b.Y=5/6X-1/6
C.Y=2/3X+1/5
D.y=6/5x+1/5
Answers
Answer:
(1, 2/3) (-1, -1) are the points. use the slope formula to find the slope y2-y1/x2-x1
(-1 - 2/3) / (-1 -1) (answer both sides of the division side)
-5/3 / -2 (divide)
slope = 5/6 (the slope)
plug in values you know into point-slope form (y -y1) = m(x-x1)
y - (-1) = 5/6 (x - (-1) (i chose the easier point to plug in. two neg. make a pos. )
y +1 = 5/6 (x +1) (use the distributive property)
y +1 = 5/6x+5/6 (subtract 1 from both sides)
y = 5/6x - 1/6 or B (this is the equation)

Lake Michigan is one of five great lakes in north america.In summertime, lake Michigan recedes about 1/4 foot per hour. Lake Michigan is about 279 ft. In depth.
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, a possible question is "calculate the depth of the lake after certain number of hours (say 2 hours)"
Given
[tex]Rate = \frac{1}{4}ft/hr[/tex]
[tex]Depth = 279ft[/tex]
First, we calculate the depth receded.
If the rate is 1/4ft per hour
Then
The Depth receded in 2 hours is:
[tex]Receded = \frac{1}{4} * 2[/tex]
[tex]Receded = \frac{2}{4}[/tex]
[tex]Receded = 0.5ft[/tex]
The new depth is then calculated as:
[tex]New\ Depth = 279ft - 0.5ft[/tex]
[tex]New\ Depth = 278.5ft[/tex]

x = 10√3
Step-by-step explanation:
The Pythagorean theorem tells you ...
FB^2 = BC^2 +CF^2
FA^2 = FB^2 +BA^2
Substituting for FB^2, we have ...
FA^2 = BC^2 +CF^2 +BA^2 = x^2 +x^2 +x^2
FA^2 = 3x^2
FA = x√3 = 30 . . . . take the square root and substitute for FA
x = 30/√3

===================================================
Explanation:
The combination of angle x and the 93 degree angle forms x+93. This obtuse angle is congruent to 130 because these two angles are alternate interior angles and because line L is parallel to line M.
So,
x+93 = 130
x+93-93 = 130-93 .... subtracting 93 from both sides
x = 37

find the angle p (add a explanation too)
Answers
Step 1: Find the sum of the interior angles
Use this formula: 180 x (n - 2)
n is the number of sides of the polygon
Work:
180 x (4 - 2)
180 x 2
360
Step 2: Find the angle right above the 94 degree angle
The entire angle (a circle) is equal to 360 degrees. To find the part we're looking for (inside of the polygon), we need to subtract the angle we already know from 360.
Work:
360 - 94
266
Step 3: Set up an equation to find the missing angle p
We now know every angle except p! And we know the sum of the interior angles. Knowing this information makes it really easy to set up an equation.
360 = 12 + 75 + 266 + p
360 = 353 + p
p = 7 degrees
Does this answer make sense?
Yes! Although the drawing may not be to scale, it is very possible that angle p could be 7 degrees because of how 12 degrees looks on this graph.
Hope this helps!! :)
