Answer:
Hi again
4/x-1
Step-by-step explanation:
Same thing
4÷x is 4/x
Less 1
4/x-1
To find the mean, you add all the numbers together and then divide by the number of numbers (6).
4 + 12 + 20 + 24 + 32 + 40 = 132
132/6 = 22
To find the mean absolute deviation, you will find the distance between each number and the mean and then divide this by 6 as well.
(22-4) +(22-12)+(22-20)+(24-22)+(32-22)+(40-22)
18 + 10 + 2 + 2 + 10 + 18 = 60
60/6 = 10
The mean absolute deviation is 10.
The correct answer is that Stefano should have divided by 6 when finding the mean absolute deviation.
We know that ratios can be shown with both fractions and colons.
20:705
or
It also looks like we can simplify this by dividing by 5.
20/5 = 4
705/5 = 141.
This means that for every 4 teachers, there are 141 students.
The ratio for teachers to students is:
4 : 141
It will take 250 seconds for it to reach the bottom. To find this I did 17.5 divided by .07.
Answer:
X intercept is -7 and Y intercept is 7.
Step-by-step explanation:
In order to find X intercept of an equation ,we put y =0
and for Y intercept we put x =0
therefore Y intercept of given equation y = x+7 is
plugging x =0 in the equation ,we get
y = 0 +7 = 7
y = 7 ,Y intercept is 7
For X intercept ,we plug y =0
0 = x+7
x = -7
So X intercept is -7
And Y intercept is 7
