The summary stats for Acorn Data from 1995 is as follows:Riverside:Mean = 5.525Stdev = 0.266Var = 0.061N = 20RidgelineMean = 4.456Stdev = 0.799Var = 0.413N = 20Using GraphPad QuickCals, determine what would happen to the t-value if the Riverside group decreased to 2.627? The calculated t value would not change. The calculated t value would most likely be inaccurate. The calculated t value would increase. The calculated t value would decrease.

Me write an equation for the interior angles of this triangle that uses the triangle sum theorem

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

Find the perimeter of the triangle with vertices  d(3, 4),  e(8, 7), and  f(5, 9). do not round before calculating the perimeter. after calculating the perimeter, round your answer to the nearest tenth.
