A student uses data to find the quadratic regression function h= -0.81t? + 19.93t,
which models an object's height, h, in
meters, t seconds after it is launched
upward from the surface of the moon.
Which is the best estimate of the
height of a rock 3.1 seconds after it is
launched?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

the answer to this question depends on certain assumptions.   if the 6-pint jar starts out empty, and the 3-pint jar full, pouring the 3 pints into the 6-pint jar results in a half-full 6-pint jar.   if we refill the 3-pint jar and then pour its contents into the half-full 6-pint jar, then the 6-pint jar will be full.
