Answer:
Step-by-step explanation:
If the regular price of a T-shirt is 10 USD and the store sells off its wares at 80% of its regular price, then the price at which the store would still the aforementioned T-shirt would be 80% of its 10 USD price.
80% of $10 =
0.8 * 10 = $8
This means that the price at which the T-shirt will go for, due to the ongoing sales will be $8.
Also, being asked to find the 10% and 20% of $10 is just as simple
10% of $10 =
0.1 * 10 = $1
20% of $10 =
0.2 * 10 = $2
Therefore, the 10% and 20% of $10 is $1 and $2 respectively.

Answer with explanation:</h2>
According to the Binomial probability distribution ,
Let x be the binomial variable .
Then the probability of getting success in x trials , is given by :
, where n is the total number of trials or the sample size and p is the probability of getting success in each trial.
As per given , we have
n = 15
Let x be the number of defective components.
Probability of getting defective components = P = 0.03
The whole batch can be accepted if there are at most two defective components. .
The probability that the whole lot is accepted :
∴The probability that the whole lot is accepted = 0.99063
For sample size n= 2500
Expected value : 
The expected value = 75
Standard deviation : 
The standard deviation = 8.53
<span>Given:
visited museum didn't visit museum Total
visited zoo 9 14 23
didn't visit zoo 5 2 7
Total 14 16 30
Simply look at the table and check the number that corresponds to visitors who visited the museum but did not visit the zoo. The number is 5.
Divide it by the total number of people surveyed. Total is 30.
Probability visited the museum but did not visit the zoo = 5/30 = 0.16666 or 16.67%</span>
{ solution is attached below}
n - 8 < -8
< is similar to = in this case
n < -8 + 8
n < 3
The answer would be bubble #3.
