It's kinda hard to see the top 2 so I wont answer them only because I can't see it clear enough and I don't want to give the wrong answer because i thought it said something else but i can help with #10, anyway here's what I got it might not be fully right because I'm learning this same thing, but I'm pretty good with it. 

#10. Since a triangle has a total measure of 180 degrees, you have to figure out how to get each angle to equal 180 when all 3 are added together, so here's how you solve it:

Step 1- Figure out what X represents in this question. Let's start with angle W. They already give you part of the equation, which is W= x +6. So now the next angle is X which the equation is X= 5x-12. The 3rd angle is Y= 7x-48.

Step 2- Add/ subtract the equation for each angle, and write what you got for your answer after each equation. 

Step 3- After you have done step 2, try to mess around with each angle (multiply,subtract, etc.) until you got the angles to where they equal to 180 when added together.

Step 4- Write down the value of X in the blank that helped you solve the question. Do the same thing for the 3 angles.

I'm not giving the answer, but do the steps and you will be able to get it. It also helps you so you can do these on ur own.

I don't know if these are the steps u were taught, but this is how my math teacher taught me and the class.

Hope this helps, tell me if it got u the right answer or not!! :-)

never [62]

The graph is attached and the answer to the function g(x) = (1/3)x²

Option A is the right answer.

<h3>What is a Function ?</h3>

A function is a mathematical statement that relates a dependent variable and an independent variable.

It is given that

f(x) = x²

It has been asked to determine the equation of g(x)

It can be seen from the graph the the vertex is same just the graph is scaled.

The point (3,3) is of g(x) , when the value of y at at x =3 is 9

Therefore the scale factor is 1/3

And we can do trial and error on the basis of the options given ,

The graph is attached and the answer to the function g(x) = (1/3)x²

Option A is the right answer.

For a standard normal distribution, find the approximate value of p (negative 0.78 less-than-or-equal-to z less-than-or-equal-to
topjm [15]

The approximate value of P(-0.78 ≤ Z ≤ 1.16) is obtained being 0.6593

<h3>How to get the z scores?</h3>

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have  X \sim N(\mu, \sigma)

(X is following normal distribution with mean \mu and standard deviation \sigma)

then it can be converted to standard normal distribution as

Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

P(Z \leq z) = P(Z < z) )

Also, know that if we look for Z = z in z-tables, the p-value we get is

P(Z \leq z) = \rm p \: value

For this case, we have to find:

P(-0.78\leq Z \leq 1.16)

It can be rewritten as:

P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z < -0.78) \\P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z \leq -0.78)

The p-values for Z = 1.16 and Z = -0.78 from the z-table is found as 0.8770 and 0.2177 respectively, and therefore, we get:

P(-0.78\leq Z \leq 1.16) = P(Z \leq 1.16) - P(Z \leq -0.78)\\P(-0.78\leq Z \leq 1.16) = 0.8770 - 0.2177 = 0.6593

Thus, the approximate value of P(-0.78 ≤ Z ≤ 1.16) is obtained being 0.6593
