Find the x-and y-intercepts of this equation. k(x)=-5x+1

Students in a college algebra class were given a final exam in May and subsequently retested montly with an equivalant exam. The average score $(\bar{x})$ for the class is given by the human memory model $\bar{x}=86-15\log (t+1)$
where t is the time in months after the final exam. What is the average score 5 months after the final exam? Give your answer correct to the nearest hundreth.

To calculate: The probability that the selected student received an "A" in the course.
Given Information:
A table depicting the grade distribution for a college algebra class based on age and grade.

To calculate: The probability that a student chosen randomly from the class is going to college if the number of students in a high school graduating class is 128, out of which 52 are on the honor roll, and out of these, 48 are going to college. The number of students who are not on the honor roll is 76, out of these 56 are going to college.

To state:Null hypothesis and alternative hypothesis.

A hybrid course is one that contains both online and classroom instruction. In a study performed at Middle Georgia State University, a software package was used as the main souce of instruction in a hybrid college algebra course. The software tracked the number of hours it took for each student to meet the objectives of the course. In a sample of 45 students, the mean number of hours was 80.5, with a standard deviation of 51.2.
a. Construct a 95% confidence interval for the mean number of hours it takes for a student to meet the course objectives.

Find the x-and y-intercepts of this equation.
${\displaystyle -2x+5y=20}$

To draw: The conclusion and internet the decision.
