Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want this probability:

And we can use the probability mas function and we got:
16+9 is 25 so that's he answer
Answer:
<em>Their total sales (revenue) when they break-even is $250,000</em>
Step-by-step explanation:
<u>Linear Modeling</u>
Some situations can be mathematically represented as linear functions. If we are in a situation where a linear model is suitable, then we need two independent data to build it up.
The linear function can be expressed in the slope-intercept format:
y = mx + b
Where m and b are constant values.
The total cost function for Rally Co.'s to produce x toy trucks is:
C(x) = 200,000 + 4x
Given they sell each truck for $20, the revenue function is:
R(x)= 20x
The break-even condition is when the costs and the revenue are equal:
20x = 200,000 + 4x
Subtracting 4x:
16x = 200,000
Dividing by 16:
x = 200,000/16
x = 12,500 toy trucks
The revenue at this production level is:
R(x)= 20*12,500=250,000
Their total sales (revenue) when they break-even is $250,000
