If a fair coin is tossed, the probability that it will land heads up is ½. Olivia tosses a coin 4 times, and it lands on heads 4

consecutive times. Which statement below is true?
A. If Olivia tosses the coin a fifth time, it will land on heads, because the experimental probability of landing on heads is 100%.
B. If Olivia tosses the coin a fifth time, it will most likely land on heads because the fifth toss is dependent on what happened during the first 4 tosses.
C. If Olivia tosses the coin a fifth time, there is a ½ probability that it will land on heads, because it is an independent event, and it does not matter what happened during the first four tosses.
D. If Olivia tosses the coin a fifth time, there is a 0% chance that the coin will land on heads.

Step-by-step explanation:

Volume of a cylinder = πr²h

Volume = 3207

Radius, r

Height, = 5

320π = π * 5 * r²

320 = * 5 * r²

320 = 5 * r²

r² = 320/ 5

r² = 64

r = 8 m

The lateral surface area of a cube is

LSA = 4s²

Where s = edge length

36 = 4s²

s² = 36/4

s² = 9

s =. sqrt(9)

s = 3

Look at the table of values below.
Natalka [10]

Answer:

A. y = 1 - 2x

The equation y = 1 - 2x is represented by the table.

Step-by-step explanation:

In this question you are trying to find out which is the right equations that belongs to the table of values.

For any streight line, you need the minimum of two points (x,y) to be able to draw a line that accounts for all points on that line...

If you substitute x = 1 in any of the equations, the outcome should be -1 because that is given in the table.

So try it and you will you find solely based on one of the first value that, the equations in A. and C. could be valid, because the point with coordinates (1, -1) is on the line A. and also on C.

At this time you can totally discard equations B an D because the value of y = -1 is not the outcome if you substitute x = 1. You can absolutely cross out answers B an D. Please understand what a timesaver this is; for the next substitution you only need to subsymtitue one extra coordinate (x,y) and you only have to substitute it only in equations A and C.

Try one more point, to choose between answer A and answer C. Just pick the easiest value in the table.

Please understand that you could pick eighter the x value OR YOU COULD choose the y value. It just does not matter, because the coordinate (x,y) is a pair of two numbers which are bound together by the equation given and also by all values in the table... The question remains, how fast can you distinguish which is the right equation....

After substituting another value from the table, you find that only equation A. is valid and not C (and you already discarded answers B an D remember)....

So the equation y = 1 - 2x is represented by the table, which is answer A.

Although this is a lot of text explaining the simple steps of substituting a value of the table an checking if the coordinate is a member of the equation, I hope it will save you a lot of time in the future!
