You flip a coin 8 times and record the results using 0 for heads and 1 for tails. you find the variance. is investigating this sample variance the same as investigating the sampling distribution of the variance? a. no, the sample only contains 8 coin flips. the sample needs to be much larger b. yes, only one person is necessary to flip the coin and find the variance. c. no, the sampling distribution of the variance is the distribution of the means from all samples, not just one. d. yes, the probability of getting heads and the probability of getting tails is the same

The table represents a linear function. what is the slope of the function? –6 –4 4 6

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
