This graph will start at (.5, 0) as the vertex.

To find this, all you need to do if find the point where inside the absolute value sign is equal to 0. Since the graph can never have a negative value, this will be the lowest point.

2x - 1 = 0

2x = 1

x = .5

From there, you can plot each point by going up two and to the left one.

Examples of Points: (1.5, 2) and (2.5, 4)

You can also plot the other side of the graph by going up two and to the right one.

These points can be found using the slope, which is the number attached to x (2).

Example of Points (-.5, 2) and (-1.5, 4).

Janelle and her best friend Carmen go shopping. the function p(t) = 5^4-3x^3 +2^2+24 represents how much money each girl spent b

<h2>Hello!</h2>

The answer is:

They spent $176 together.

We are given an expression which represents the money spent for each girl, it's a function of time and it will show how much they can spend in terms of hours.

Assuming that you have committed a mistake writing the equation, otherwise, the given options would not fit, the expression is:

$p(t)=5x^{4}-3x^{3}+2x^{2}+24$

Now, from the statement we know that the function represents how much money each girl spent, so, if we need to calculate how much money they will spend together, we need to multiply the expression by 2, so we have:

$p(t)=2(5x^{4}-3x^{3}+2x^{2}+24)$

Then, calculating the spent money for 2 hours, we need to substitute the variable "x" with 2.

Calculating we have:

$p(2)=2(5*(2)^{4}-3*(2)^{3}+2*(2)^{2}+24)=2(5*16-3*8+2*4+24)$

$p(2)=2(5*16-3*8+2*4+24)=2(80-24+8+24)=2*88=176$

Hence, we have that they spent $176 together.

Have a nice day!

Assuming that the null hypothesis is true, then _________ is the probability of observing a value of the test statistic that is

vladimir2022 [97]

Assuming that the null hypothesis is true, then<u> p-Value</u> is the probability of observing a value of the test statistic that is at least as extreme as the value actually computed from the sample data.

Step-by-step explanation:

<u>The p-value is the probability that a random sample that is selected produces as the value of the test statistic is at least as extreme as the observed value when H0 is true.</u>

<u>The p-value as measure of how surprising our result is if the null hypothesis is true.</u>

So ,we can state that- Assuming that the null hypothesis is true, then<u> p-Value</u> is the probability of observing a value of the test statistic that is at least as extreme as the value actually computed from the sample data.
