From this point go UP (rise) another 3 units, then 1 unit to the RIGHT (run), and put another point. This is the second point. Connect the points and it should look like this:----- EXAMPLE 2: y = -3x + 2 SOLUTION: Y-intercept = 2, slope = Start by graphing the y …

Going down the river a boat went 11 mph. Going up the river it only went 3 mph. What is the speed of the current? How fast would the boat go if there were no current?: Let s = speed in still water Let c = speed of the current: Two equations, use elimination here s + c = 11 s - c = 3-----Addition eliminates c find s 2s = 14 s = 7 mph in still water

The average stock price for companies making up the S&P 500 is $30, and the standard deviation is $8.20. Assume the stock prices are normally distributed. a) What is the probability a company will have a stock price of at least $40? Find the z-score of 40. Formula: z(x) = (x-u)/s z(40) = (40-30)/8.2 = 1.2195

We don't have to add up the digits since 9 is a multiple of 3, sums of 9 will also get us a multiple of 3. If you solved this equation 9,999,999 = 1,000,002 + 3(n-1) then you would get the result n = 3,000,000 = 3 million I'll let the student handle the scratch work. Answer: 3,000,000 aka 3 million

Question 884189: Going Round-Trip with the World’s Fastest Land Animal According to the Travel Almanac, the world’s fastest land animal is the cheetah. It can travel at up to 70 mph. Think of this scenario: A cheetah sitting under a tree sprints toward its prey at 70 mph. It runs back to its initial spot by the tree at a modest 40 mph.

Since d = rt, after 2 minutes (120 seconds), the robber would be (42)(120) or 5040 meters ahead of the cop. The cop's approach rate to the robber is then 42-40 or 2 m/s. So since t = d/r, it would take the cops an additional 5040/2 = 2520 seconds to catch up.

A motorboat takes 5 hours to travel 200km going upstream. The return trip takes 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current? *** let x=rate of boat in still water let c=rate of current x+c=rate of boat downstream x-c=rate of boat upstream travel time *rate=distance.. 5(x-c)=200 4(x+c ...

You can put this solution on YOUR website! First, determine how many hours it took to go 162 miles. Since the car left at 7:30 and arrived at 10:30, we know it took 3 hours to travel 162 miles.

Focus only on the "A" column. Cover up everything else. There are 23 people who got an A. Of those 23 people, there are 15 males.
