Which is the graph of f(x)=3(2/3)x?
anyanavicka [17]

we have that

f(x)=3(\frac{2}{3})^{x}

Step 1

<u>Find the y-intercept</u>

we know that

The y-intercept is the value of f(x) when the value of x is equal to zero

For x=0

f(0)=3(\frac{2}{3})^{0}=3

Point A(0,3)

Step 2

<u>Find the value of f(x) for x=1</u>

f(1)=3(\frac{2}{3})^{1}=2

Point B(1,2)

Step 3

<u>Graph the point A and B to find the solution</u>

therefore

the answer in the attached figure

P(z=1.85) what is the area to the left of z= 1.85
Kisachek [45]
0.84(because 20% of the observations are about 0.84)
You've found the 80th percentile! The 80th percentile of the standard normal distribution is 0.84. That's because 80% of the observations fall below 0.84. (Note: The 80th percentile of every normal distribution is 0.84 times the standard deviation above the mean.)

In the equation 6x – 2 = –4x + 2, Spencer claims that the first step is to add 4x to both sides. Jeremiah claims that the first
Sergeeva-Olga [200]
If you would like to know who is correct, you can find this using the following step:

<span>6x - 2 = -4x + 2

Spencer: 
</span>6x - 2 = -4x + 2       /+4x
6x - 2 + 4x = -4x + 2 + 4x
10x - 2 = 2

Jeremiah:
6x - 2 = -4x + 2      /-6x
6x - 2 - 6x = -4x + 2 - 6x
-2 = -10x + 2

They both are correct. But in Jeremiah's version of solving the equation, we would have to multiply equation by -1 (or add 10x to both sides), which we don't have to do in the Spencer's version.
