Experimental Probability = 2/3
To find the experimental probability that the tack lands point-up for student 4, we can use the following equation
![\frac{Point-up}{Attempts}\\\frac{4}{6} or\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7BPoint-up%7D%7BAttempts%7D%5C%5C%5Cfrac%7B4%7D%7B6%7D%20or%5Cfrac%7B2%7D%7B3%7D)

Answer:
0.01083 or 1.083%
Step-by-step explanation:
This problem can be modeled as a binomial probability model with probability of success p = 0.56.
The probability of x=13 successes (a college student being very confident their major would lead to a good job) in a number of trials of n=15 is:
![P(X=x) = \frac{n!}{(n-x)!x!} *p^x*(1-p)^{n-x}\\P(X=13) = \frac{15!}{(15-13)!13!} *0.56^{13}*(1-0.56)^{15-13}\\P(X=13) = 0.01083=1.083\%](https://tex.z-dn.net/?f=P%28X%3Dx%29%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-x%29%21x%21%7D%20%2Ap%5Ex%2A%281-p%29%5E%7Bn-x%7D%5C%5CP%28X%3D13%29%20%3D%20%5Cfrac%7B15%21%7D%7B%2815-13%29%2113%21%7D%20%2A0.56%5E%7B13%7D%2A%281-0.56%29%5E%7B15-13%7D%5C%5CP%28X%3D13%29%20%3D%200.01083%3D1.083%5C%25)
The probability is 0.01083 or 1.083%.
Answer: it is linear
Step-by-step explanation: Find the degree of the equation to determine if linear.
Answer:
165 is greater than or equal to 17.75x+5.25; 9 is greater than or equal to x
Step-by-step explanation:
The problem states that they have no more than $165. This means that they either use all the money, or they have leftover money, which means you need to use the 'greater than or equal to' sign. It says that tickets are $17.75 a person, and we're trying to find the number of people (x). You can write this as 17.75x. There is also a parking fee to add on to the equation, which is represented as +5.25. Now, we can solve!
I'm going to use an equal sign to replace the inequality symbol, but make sure to add the symbol at the end of the problem.
165=17.75x+5.25
159.75=17.75x
9=x
Our final answer is 9 is greater than or equal to x. Hope this helps!
