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.

a rectangle has an area of x2+8x+15 square meters and a width of x+3 what expression represents the length of the rectangle
anzhelika [568]

Answer:

1x + 5

Step-by-step explanation:

Since the area of a rectangle of width w and length l is A = l*w,

length = Area / Width.

Here,                             x^2 + 8x + 15

length of rectangle  = ----------------------

                                            x + 3

Use synthetic division to perform the above.  The coefficients of the quadratic are a = 1, b = 8 and c = 15, and the divisor is -3 (from (x + 3).

-3      /  1        8        15

                    -3        -15

        -------------------------

            1         5        0

Since the remainer is zero (0), -3 is a root and 1x + 5 is a factor of the quadratic.  This factor, representing the length of the rectangle, is 1x + 5.

Next time, kindly share the answer choices.  Thank you.
