A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled. Which statement shows the meaning of the driver’s equation? Select two options. Three dollars added to $0.50 is the same as $9.50. Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents. Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents. The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50. The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

According to a research study, parents with young children slept 6.4 hours each night last year, on average. a random sample of 18 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.8. this data has a sample standard deviation of 0.9. (assume that the scores are normally distributed.) researchers conduct a one-mean hypothesis at the 5% significance level, to test if the mean amount of time parents with young children sleep per night is greater than the mean amount of time last year. the null and alternative hypotheses are h0: μ=6.4 and ha: μ> 6.4, which is a right-tailed test. the test statistic is determined to be t0=1.89 using the partial t-table below, determine the critical value(s). if there is only one critical value, leave the second answer box blank.
