The mean absolute deviation is given by the next formula:
Where n is the number of points in the data set and x with a bar on top is the mean.
In our case,
and n=25.
Then,
Finally,
The answer is 1.4 once rounded.
Hey There!
To find the answer subtract 70-56, to find the change, the change is 14.
Have A Brainly Day!
Looking at the graph:
we know that the y-intercept is 4
slope is
we can use (0,4) as point 1 and (6, -4) as point 2 to find the slope
using slope intercept form your answer should be
y=(-4/3)x+4
also, your answers repeat themselves. A and B are the same and so are C and D
Answer:
Step-by-step explanation:
a.=200+50+20+7=277
b.=1000+500+100+30+5=1635
c.=1000+200+20+9=1229
d. =2000+9=2009
Answer:
x= 10
Step-by-step explanation:
A triangle always sums up to 180 degrees. (Remember this)
So, tha equation would be: 73+(4x-1)+(6x+8)= 180.
Step 1- Add common variables.
(4x+6x)+73+8-1= 180
10x+73+8-1= 180
Step 2- Add to simplify.
10x+(73+8-1)= 180
10x+80= 180
Step 3- Subtract 80 to both sides.
10x+80= 180
-80 -80
10x= 100
Step 4- Divide both sides by 10.
<u>10x</u>= <u>100</u>
10 10
x= 10
