A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever)

Function f is an exponential function.

Wewaii [24]

Answer:

The output value increases by a factor of 2 as each input value increases by 1.

Step-by-step explanation:

Given:

Function $f(x)$ is an exponential function.

The factor by which $f(x)$ increases with increase in $x$ is same as finding the ratio of two consecutive output values.

When $x$ increases from -4 to -2, $f(x)$ increases from $\frac{3}{16}\ to\ \frac{3}{4}$ . Therefore, the factor by which the output changes is:

$r=\frac{\frac{3}{4}}{\frac{3}{16}} =\frac{3}{4}\times \frac{16}{3}=4$

The increase in input value for increasing output value by a factor 4 is given as:

$\Delta x=-2-(-4)=-2+4=2$

So, with the increase of input value by 2, the output value increases by a factor of 4.

Therefore, with the increase of input value by 1, the output values increases by a factor $\frac{4}{2}=2$

Thus, the output value increases by a factor of 2 as each input value increases by 1.

Suppose that you have a fair coin and you label the head side as 1 and the tail side as 0. a. Now, you are asked to flip the coi

ValentinkaMS [17]

Answer:

In the explanation

Step-by-step explanation:

a) We need to write down the sample space for two coin flips.

X={HH,HT,TH,TT}

P(HH)=0.25 X=2

P(HT)=0.25 X=1

P(TH)=0.25 X=1

P(TT)=0.25 X=0

Then

X=0, P(0)=0.25

X=1, P(1)=0.50

X=2, P(2)=0.25

b) If we filp the coin 4 times we have

4 H + 0 T X=4 P(X)=1/16=0.0625

3 H + 1 T X=3 P(X)=4/16=0.250

2 H + 2 T X=2 P(X)=6/16=0.375

1 H + 3 T X=1 P(X)=4/16=0.250

0 H + 4 T X=0 P(X)=1/16=0.0625

c) If we flip the coin 10 times

10 H + 0 T X=10 P(X)=1/1024=0.001

9 H + 1 T X=9 P(X)=10/1024=0.0098

8 H + 2 T X=8 P(X)=45/1024=0.0439

7 H + 3 T X=7 P(X)=120/1024=0.1172

6 H + 4 T X=6 P(X)=210/1024=0.2051

5 H + 5 T X=5 P(X)=252/1024=0.2461

4 H + 6 T X=4 P(X)=210/1024=0.2051

3 H + 7 T X=3 P(X)=120/1024=0.1172

2 H + 8 T X=2 P(X)=45/1024=0.0439

1 H + 9 T X=1 P(X)=10/1024=0.0098

0 H + 10 T X=0 P(X)=1/1024=0.001
