Answer:
Mean = 4.8875
Median = 4.6
Mode = 4.5 and 7.7
Step-by-step explanation:
Mean is the sum of total of data divided by the sample size
Sum total = 1.5 + 4.7 + 6 + 7.7 + 7.7 + 4.5 + 2.5 + 4.5
Sum total = 39.1
Sample size = 8
Mean = 39.1/8
Mean = 4.8875
To get the median we need to first rearrange
1.5, 2.5, 4.5, 4.5, 4.7, 6, 7.7, 7.7
Median = 4.5 + 4.7/2
Median = 4.6
Hence the median is 4.6
Mode is the value occuring the most. Since 4.5 and 7.7 both occurs twice, hence the mode of the data is 4.5 and 7.7
Answer:
x=-5 or x=3
Step-by-step explanation:
when multiplying anything by 0, the answer will be zero
In this case, one of the two factors has to be equal to 0
start by splitting into
(x+5) = 0
solve the equation
subtract 5 from both sides
x = -5
now, repeat for the other binomial
x-3 = 0
add 3 to both sides
x=3
Answer:
15x
Step-by-step explanation:
9x + 6x = 15x
-4 +4 = 0

Answer:
- short leg: x; long leg: 12; hypotenuse: y
Step-by-step explanation:
The sides of the triangle can be read from the figure:
- short leg: x
- long leg: 12
- hypotenuse: y
The ratios tell you ...
long leg = x√3 = 12
x = 12/√3 = 4√3 . . . . . divide by √3. (same as multiply by (√3)/3)
2x = 2·4√3 = 8√3
Then the missing sides are ...
- short leg: 4√3
- long leg: 12
- hypotenuse: 8√3
The equation of line perpendicular to given line passing through (8,-5) is:
Step-by-step explanation:
Given equation of line is:
Let m1 be the slope of given line
then
m1 = 4/3
Let m2 be the slope of line perpendicular to given line
As we know that the product of slopes of two perpendicular line is -1
Equation of line is given by:
Putting the value of the slope
Putting the point (8,-5) in equation
Putting the value of b in equation
Hence,
The equation of line perpendicular to given line passing through (8,-5) is:
