On a skydiving trip, Victor boards a plane which immediately takes off and flies 12 minutes as it
climbs to 8,000 feet. The plane remains at this elevation for 5 minutes and then climbs again
over the next 3 minutes to 10,000 feet. The plane remains at this height for 2 minutes until
Victor makes his jump. He then free falls for 45 seconds until he reaches a height of 3,000
and ueploys his parachute. It takes Victor another 8 minutes to slowly make his way back to the
t was the average rate of change (in feet per minute) of Victor's elevation between
time 12 minutes and 20 minutes?

The balance of susu's savings account can be represented by the variable b. the inequality describing her balance b > $30 . which could be a solution to the inequality?

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.

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
