And evaluate:
In conclusion, our answer is A.
Enlarge means to make bigger
From the information we have, we can conclude that this quadrilateral is a rectangle. The reason behind this is because rectangles have two sets of parallel sides, which makes them different from squares.

Let p = her pay per week.
<span>"Karissa earns $200 per week plus $25 per item she sells."
She earns a fixed amount of $200 per week no matter how much she sells.
Then she earns an additional variable amount that depends on the number of items she sells. It is $25 per item.
p = fixed amount + variable amount
The variable amount is:
If she sells 1 item, she earns 25 * 1
If she sells 2 items, she earns 25 * 2
If she sells 3 items, she earns 25 * 3
If she sells n items, she earns 25 * n
The variable amount she earns is 25n, where n is the number of items she sells.
</span>
<span>p = fixed amount + variable amount
p = 200 + 25n

Answer:
P(X = 3) = 0.1442
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
We have to find P(X = 3).
