PLEASE HELP. WILL MARK BRAINLIESTA medical test has a 95% accuracy of detecting a Condition Z if the person has it. It also has a 97% chance to indicate that the person does not have the condition if they really don't have it. If the incidence rate of this disease is 10 out of every 100:1.] What is the probability that a person chosen at random will both test positive and actually have the disease (i.e., get a true positive)?2.] What is the probability that a person chosen at random will test positive but not have the disease (i.e., get a false positive)?

A middle school student studies the amount of time seventh and eighth graders spend playing video games on the weekend by collecting data from a large random sample of students in each grade. Her theory is that seventh graders will spend more time playing video games because eighth graders have more difficult classes and must spend more time on school work. In her samples, the mean time spent playing video games on the weekend is 122.4 minutes for seventh graders and 88.6 minutes for eighth graders. Assuming there are no outliers or skew, do the results support the student's theory? Select from the drop-down menus to correctly complete the statements. Since the samples were large and randomly chosen, we can use the samples to understand the populations. Because the sample mean for seventh graders is the sample mean for eighth graders, the results support the student's theory.

The table below represents the distance of a truck from its destination as a function of time:   Time (hours) x Distance (miles) y          0                   330          1                    275          2                   220          3                    165         4                    110 Part A: What is the y-intercept of the function, and what does this tell you about the truck? Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 4 hours, and tell what the average rate represents. Part C: What would be the domain of the function if the truck continued to travel at this rate until it reached its destination?
