Answer:

(5,3)

Step-by-step explanation:

If you graph the equation y=x-2 and plot all the points given as options, you can see that (5,3) lies on the line, while all others don't. This means that option D (5,3) would get generated by the equation.

Another way to do this is to substitute 'x' and 'y' for the points given. If they satisfy the equation, then it would be correct.

<h3>Option A (5,7):</h3>

7=5-2\\\boxed{7\neq3}

Option A is incorrect.

<h3>Option B (7,14):</h3>

14=7-2\\\boxed{14\neq5}

Option B is incorrect.

<h3>Option C (7,9):</h3>

9=7-2\\\boxed{9\neq5}

Option C is incorrect.

<h3>Option D (5,3):</h3>

3=5-2\\\boxed{3=3}

Option D is correct.

Option D should the the correct answer.

Which graph represents the exponential function below f(x)=5(3)^x-1
castortr0y [4]

Answer:

Given Exponential Function is :

f(x)=5\times3^x-1

We have check which graph represent given Exponential Function,

let, y=5\times3^x-1

Put x = 0, we get

y=5\times3^0-1

y = 5 × 1 - 1 = 4

One of the passing through point = ( 0 , 4 )

Now, Put y = 0, we get

0=5\times3^x-1

3^x=\frac{1}{5}

log\,(3^x)=log\,(0.2)

x\:log\,3=log\,0.2

x=\frac{log\,0.2}{log\,3}

x=\frac{log\,0.2}{log\,3}

x = -1.465

Another passing through point is ( -1.465 , 0 )

So, Clearly No Given Option in attached is correct.

Correct Graph is attached.

Suppose a basketball player has made 223223 out of 406406 free throws. If the player makes the next 22 free throws, I will pay y
makkiz [27]

Answer:

Expected value E = $0.45

Step-by-step explanation:

Expected value E = P×w - P'×l

Where;

P = probability of making the next 2 throw.

P = 223/406 × 223/406 = 0.3017

P' = probability of not making a throw.

P' = 1 - P = 1 - 0.3017

P' = 0.6983

w = expected win = $20

l = Expected loss = $8

Substituting the values;

E = 0.3017 × $20 - 0.6983 × $8

E = $0.4476

Expected value E = $0.45
