The mean absolute deviation of the data set is 1.6
Data obtained from the question0, 0, 0, 5, 0
Determination of the mean Data => 0, 0, 0, 5, 0Summation of data = 0 + 0 + 0 + 5 + 0 = 5Number of data = 5Mean =?Mean = Summation of data / Number of data
Mean = 5 / 5

Answer:
-2
Step-by-step explanation:
You can see that when x goes up by 1, y goes down by 2. This means the rate of change is -2
Answer:
The rate of change is -2
Step-by-step explanation:
Take any two points from the graph. (0,-4) and (-2,0). Plug them into the equation y2-y1/x2-x1. In this case the equation would be 0--4/-2-0. Simplify this and get 0+4/-2-0. Simplify again and get 4/-2 which is -2
Therefore the rate of change is -2

Answer:
987650Step-by-step explanation:
The largest 6-digit number is:
999999We need all digits different and the last one 0 or 5 because the number is the multiple of 5.
9876 are the first 4 digits and the last two 50 or 45, we'll chose 50 as 45 is smaller.

Are these triangles similar? Why?
A. Yes, SSS~ Postulate
B. Yes, SAS~ Postulate
C. Yes, AA~ Postulate
D. No, they are not similar.
Answer:
Step-by-step explanation:
<Q is common to both triangles.
130 / 40 = 3.25
Call DQ = x
40/130 = x / (x + 72) Cross multiply
40*(x + 72) = 130*x
40x + 2880 = 130x Subtract 40 x from both sides
2880 = 90 x Divide by 90
x = 32
(72 + 32)/32 = 104/32 = 3,25
The ratios are the same.
Therefore the triangles are similar by SAS
An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
Find the term of the sequence that has value -93?
Answer:
n = 50
Step-by-step explanation:
Let a be the first term and d be the common difference.
An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
[tex]a_n=a+(n-1)d[/tex]
According to the given condition,
[tex]a_2=3\\\\a_{10}=-13[/tex]
or
[tex]a+(2-1)d=3\\\\a+d=3\ ...(1)\\\\a+(10-1)d=-13\\\\a+9d=-13\ ...(2)[/tex]
Subtract equation (1) from (2).
a+9d-(a+d) = -13-3
8d = -16
d = -2
Put the value of d in equation (1).
a+(-2) = 3
a = 3+2
a = 5
Now,
[tex]a+(n-1)d = -93\\\\5+(n-1)(-2)=-93\\\\5-2n+2=-93\\\\7+93=2n\\\\2n=100\\\\n=50[/tex]
So, 50th term has the value of -93.

Answer:
n = 2
Step-by-step explanation:
Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4
This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.
We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.
-n = -2,
n = 2

A taxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. The rule c = 0.40m + 1.75 describes the relationship between the number of miles m and the total cost of the ride c.
a. What is the charge for a 1-mile ride?
b. What is the charge for a 2.7-mile ride?
A. $2.15; $2.83
B. $0.40; $5.13
C. $0.40; $1.08
D. $1.75; $2.15
Answer:
A. $2.15; $2.83
Step-by-step explanation:
2.83
c = 0.4. * 2.7 + 1.75
=> c = 2.83
4(2.7)+1.75
1.08+1.75=2.83
$2.83 is correct.
c=0.40(2.7)+1.75
c=1.08+1.75
c=2.83
Answer:
2.83 dollars
Step-by-step explanation:
Fixed charges made by the taxi company for a ride =
Additional charge for each mile travelled =
Hence equation for cost is given by
where m is thenumber of miles travelled.
To find out the charge for a 2.7 mile ride substitute m = 2.7
Total cost for 2.7 mile ride is 2.83 dollars

Given the equation of a line: y = (2/3)x + 1. Select the equation of the line PARALLEL to this line
Answer:
y = (2/3)x + K, where K is any number except 1
Step-by-step explanation:
In the slope-intercept form of the linear equation, y = mx +b, the 'm' is for the slope, m = 2/3.
Any line that also has a slope of 2/3 will be parallel.
y = (2/3)x - 10 will be parallel
y = (2/3)x + 12 will be parallel
y = (2/3)x - (1/2) will be parallel
y = (2/3)x + 5,391 will be parallel

Linda is paid double her normal hourly rate for each hour she works over 40 hours in a week. Last
week she worked 52 hours and earned $544. What is her hourly pay?
Answer:
her hourly pay is £8.50
Step-by-step explanation:
h= hourly pay
n = number of hours worked over 40 hours in a week
week pay = 40h + (n x 2 x h)
544 = 40h + 2nh
52 - 40 = 12, so n = 12
544 = 40h + 2 x 12 x h
544 = 40h + 24h
544 = 64h
544/64 = 8.5 h=8.5 (£8.50)
just to check:
£8.50 x 40 = £340
£8.50 x 2 x 12 = 204
340 + 204 = 544 yayy the answer is correct
hope this helps x

What is the area of the figure below?
The perimeter of the triangular park shown on the right is 11x - 7. What is the missing length?
Answer:
6x-4
Step-by-step explanation:
the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter
11x-7 = 4x+2 + x-5 + y
solve for y
11x-7 = 5x -3 + y
11x-4 = 5x + y
6x-4 = y
