Scott did an experiment in which he flipped a coin 100 times. His coin landed on heads 40 times and tails 60 times. What conclusions could your draw from Scott’s experiment? Select all that apply:

A. Scott did not do the experiment right.
B. The experimental findings are close to the theoretical probability of 50%.
C. There must have been a mistake in Scott’s data since the experimental probability is not close to the theoretical probability.
D. You cannot draw a conclusion about the experiment unless you do it yourself.
E. If Scott performed more trials and flipped the coin 1000 times, the experimental probability would be expected to be closer to the theoretical probability of 50%

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

its a, i had the same answer, its from study island right
