Answer:
c) skewed to the right.
Step-by-step explanation:
We need to remember that is a distribution is skewed to the right then we have the following condition satisfied:
And if is skewed to the left then we have:
If the distribution is symmetric we need to satisfy:
For this case since we have most of the values between 200000 and 500000 when we put atypical values like 15000000 that would affect the sample mean and on this case the sample mean would larger than the sample median because the median is a robust measure of central tendency not affected by outliers.
So for this special case we can say that the 
. And probably the median would be higher than the mode so then we can conclude that the best answer for this case would be:
c) skewed to the right.
Answer:
It will take 20 minutes to pump out 1000 unit milk tank
Step-by-step explanation:
The pump on the milk tank pumps milk out at a rate of 50 units per minute,
1 minute = 50 units
x minutes = 1000 units
Using the unitary method x= = 1000*1/50= 20 minutes
It will take 20 minutes to pump out 1000 unit milk tank
It’s called the associative law you can add numbers in any order you want
Answer:
1 day: 4480
2 days: 8960
3 days: 13440
---- function inverse
Step-by-step explanation:
Given
Solving (a): The amount present after 1 day.
Here, 
So:
Solving (b): The amount present after 2 days.
Here, 
So:
Solving (c): The amount present after 3 days.
Here, 
So:
Solving (d): The inverse function of:
Replace f(x) with y
Swap x and y
Rewrite as:
Divide by 4
Take square roots
Replace y with function inverse
