4 glue sticks cost $7.76 Which equation would help determine the cost of 13 glue sticks?
2 answers:
Answer:
13 glue sticks cost $25.22.
Step-by-step explanation:
4 blue sticks cost $7.76, this means that one glue stick costs
$7.76/4 = $1.94.
Let be the cost of the glue sticks, and
be the number of glue sticks; then
We can use this equation to find the cost of 13 glue sticks; we just put into our equation and it gives:
So 13 glue sticks cost $25.22.

Answer:
P(X=0)=0.000008
P(X=1)=0.00176
P(X=2)=0.057624
P(X=3)=0.941192
Step-by-step explanation:
Probability of correct classification = p = 0.98
Probability of incorrect classification = q = 1 - p = 0.02
The probability of success and failure is the same for all the trials. The trials are independent of each other and the number of trials is fixed i.e. n = 3.
This satisfies all the conditions of a Binomial Experiment. So we can use Binomial experiment to model the probability mass function.
The general formula of a binomial probability is:
Here x denote the number of successes, which can be {0, 1, 2, 3}. So we need to evaluate the above equation for each value of x to determine the probability Mass function of X, as shown below:
