Not only are giraffes tall, the giraffe is one of the worldâs heaviest animal. A wildlife biologist believes that, on average, giraffes in Kenya weigh more than 2000 pounds. Twenty giraffes in Kenya were weighted and their average weight was 2075 pounds. Assume this data is normally distributed, the sample is random, and a population standard deviation of 174 pounds.

Go through the six steps of hypothesis testing to see if there is evidence to support the biologist's claim at a=0.04.

John makes $10.50 pers hour what expression represens how much he will make if he works h hours

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Aye asap pls ! markin da brainiest too ! btw da step choices are all add, distribute, divide, n subtract
