Answer:
Now we can calculate the absolute deviations from the mean for each value:
|0.4-0.4|=0
|0.2-0.4|=0.2
|0.4-0.4|=0
|0.6-0.4|=0.2
And adding these 4 values and dividing by 4we got the MAD on this case:
Step-by-step explanation:
We have the following dataset given:
0.4,0.2,0.4,0.6
In order to calculate the MAD we need to calculate the sample mean first with this formula:
Replacing we got:
Now we can calculate the absolute deviations from the mean for each value:

Answer: B, $4.41 per shirt
Step-by-step explanation:
To figure this out you want to first take the 200 shirts and multiply them by the cost of $2.80. This gives you a total of $560, without tax. The tax is 5%, so you want to take 560 and multiply it by .05 to find the amount of tax. This leaves you with $28 of taxes. Add that onto the already cost of $560, and it gives you a grand total of $588. She wants to sell the shirts with a 150% markup, so all you do is first find what Michelle really paid for each shirt with tax. Take the total cost of 588 and divide it by the number of total shirts which is 200. 588/200=$2.94 per shirt that Michelle paid. Times that by 1.5% and you get $4.41 per shirt that Michelle is selling.

Answer:
0.3125
Step-by-step explanation:
When a fair coin is tossed we find that
there are only two outcomes
Each toss is independent of the other
Hence if Xis no of heads then X is binomial with n = 5 and p = 0.5
Using binomial formula we can find probability for getting 3 heads exactly.
Required probability
= P(X=3)
=
