3. Greater than
Median is the middle number of the data set. But in this senario, there are 2 numbers in the middle. So you can take 4+5/2=4.5
To find Mean, you can must take all the numbers in the data set divided by the number of data collected.
In this case, (3+3+4+5+5+9)÷6
You will find that the mean is greater than the median.
Answer:
{-9.5, 1,7}
Step-by-step explanation:
For y =f(x)
domain is list of all values of x and range is list of all values of y
Given
ƒ(x) = 3x – 5
domain = {–1.5, 2, 4}.
thus,
range will be value of f(x)
when x = -1.5
x = 2 and x = 4
Thus,
for x = -1.5
ƒ(x) = 3*-1.5 – 5 = -4.5 - 5 = -9.5
\
for x = 2
ƒ(x) = 3*2– 5 = 6 - 5 = 1
for x = 4
ƒ(x) = 3*4– 5 = 12 - 5 = 7
thus,
range of ƒ(x) = 3x – 5 is {-9.5, 1,7}
Remember that the total of the angles always equals 180 degrees
4x + 2 + 8 + 6x + 30 = 180
Now solve
4x + 2 - 2 + 8 + 6x + 30 = 180 - 2
4x + 8 - 8 + 6x + 30 = 178 - 8
4x + 6x + 30 - 30 = 170 - 30
4x + 6x = 140
10x = 140
10x ÷ 10 = 140 ÷ 10
x = 14
Now that we know what x is we can fill in the blanks
4(14) + 2
58 + 2
58
Angle O is 58 degrees
8 + 6(14)
8 + 84
92
Angle R is 92 degrees
To check we can add them all up
30 + 58 + 92 = 180
x = 14
