a coin is flipped eight times where each flip comes up either heads or tails. how many possible outcomes: 1). are there in total
Ymorist [56]

There are 256 ways in total and 56 possible outcomes contain exactly three heads. The possible outcomes contain at least three heads is 219.

Consider the provided information.

A coin is flipped eight times where each flip comes up either heads or tails.

Part (a) How many possible outcomes are there in total?

Each time we flip a coin it comes up either heads or tail.

Therefore the total number of ways are: 2⁸ = 256

Hence, there are 256 ways in total.

Part (b) contain exactly three heads?

We want exactly 3 heads, therefore,

n=8 and r=3

According to the definition of combination:

To get exactly 3 heads,

n=8 and r=3

(⁸C₃ ) = 8! / 3!(5!) = 56.

Therefore, there are 256 ways in total and 56 possible outcomes contain exactly three heads. The possible outcomes contain at least three heads is 219.

You know the slope of a line and a point on the line that is not the y-intercept. Can you use a graph to write the equation of t
Gnoma [55]
Sure you could as long as you have the point.

for example let's say the slope is 2 and the point we are given is (4,4)

we know that:
y = mx + b
plug in the values given
x=4
y=4
m=2

4 = 2(4) + b
b, the y intercept equals -4.

so:

y = 2x - 4
in this case
