Here we can see that the blue line cuts exactly half way through the angle that the black line makes with x axis

That is all the x values are halved

Which implies all the x value of the black line are divided by 2 to form the points on the blue line

so that give us the function

y=\frac{1}{2} x

Answer:

Option D.

Step-by-step explanation:

It is given that black line is the graph of y=x.

We need to find the equation of blue line.

Both lines passes through (0,0) it means y is directly proportional to x.

y\propto x

y=kx

where k is constant of proportionality.

From the given graph it is clear that the black line is steeper than the blue line. It mean k<1.

If k is a very small number then the line is equivalent to x-axis. So, k≠0.001.

It means the possible value of k is 1/2. So the equation of blue line is

y=\dfrac{1}{2}x

Therefore, the correct option is D.

Hi there,
Mrrafil [7]
We have 7 people which result ----> 7 * <u />2 = <u>14 legs</u>

Also, the table has <u>4 legs</u>

The number of the big cats is 7 *7 =49 (big cats)

For every big cat we have ---> 49 * 4= <u>196 legs</u>

For every big cat we have 7 small cats which means --> 49 * 7= 343 (small kittens)

The number of legs for small kittens is 343 * 4 = <u>1372 legs</u>

The number of legs is:
<u />
<u>14+4+196+1372= 1586 legs are in total</u>

Flip a coin three times. You will win $2 for each heads. What is the expected winning (expectation of your winning)
Romashka [77]

The three coins could land any these 8 ways:

HHH, HHT, HTH, HTT, THH, THT, TTH, TTT

P(3 heads) = 1 way out of 8  or 1/8

P(2 heads) = 3 ways out of 8 or 3/8

P(1 head) = 3 ways out of 8 or 3/8

P(0 heads) = 1 way out of 8 or 1/8

x=Winnings  P(x)  E(x)=x�P(x)

    $3      1/8      $.375

    $2      3/8      $.75

    $1      3/8      $.375

  -$10      1/8     -$1.25

---------------------------

Total expectation =   $ .25
