Mountain climber Joe climbed to a mountain peak that
was 1200 feet above its base and 1500 feet east of its
base. Mountain climber Bob climbed to a mountain peak
that was 900 feet above its base and 1000 feet east of its
base.
Who climbed a steeper mountain? Explain.

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%

what shape is

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
