Help me with this problem
ryzh [129]

Answer:

Looking at the given points we know that it is going to be a triangle because it only have 3 points.  Therefore the figure is a triangle and the area formula would be A=\frac{1}{2}*b*h.

You can look at the attached graph and what we see is that our height of the triangle is from y=-3 to y=4 which means that our height is 7 units high.  We can also see that our base starts at x=-4 and ends at x=4 making us have a base of 8 units.

<u>We then plug in the values and solve</u>

A = \frac{1}{2}*7\ units * 8\ units

A = \frac{1}{2}*56\ units^2

A = 28\ units^2

Therefore, the area of our triangle is 28\ units^2

Hope this helps!  Let me know if you have any questions

Daniel wanted to know his approximate score on the final exam for his mathematics class. His professor hinted that his score was
Marizza181 [45]

Answer:

The raw score for his exam grade is 99.69.

Step-by-step explanation:

Given : The professor announced that the mean for the class final exam was 88 with a standard deviation of 7. Given Daniel's z score of 1.67.

To find : What is the raw score for his exam grade?

Solution :

The formula use to find the z-score is

z=\dfrac{x-\mu}{\sigma}

Where, z=1.67 is the z-score

\mu=88  is the means

\sigma=7 is the standard deviation

x  is the raw score for his exam grade

Substitute the values,

1.67=\dfrac{x-88}{7}

1.67\times 7=x-88

11.69=x-88

x=88+11.69

x=99.69

Therefore, the raw score for his exam grade is 99.69.

The graph of 15x + 7y = 15 is shown on the grid. Which ordered pair is in the solution set of 15x + 7y ≥ 15?
elena55 [62]

Answer:

The correct option is c.

Step-by-step explanation:

The given equation is

15x+7y=15

The given inequality is

15x+7y\geq 15

A point will contained in solution set if the above inequality satisfied by that point.

Check the point (0,-3),

15(0)+7(-3)\geq 15

-21\geq 15

This statement is false, therefore option a is incorrect.

Check the point (-3,0),

15(-3)+7(0)\geq 15

-45\geq 15

This statement is false, therefore option b is incorrect.

Check the point (3,3),

15(3)+7(3)\geq 15

66\geq 15

This statement is true, therefore option c is correct.

Check the point (-3,-3),

15(-3)+7(-3)\geq 15

-66\geq 15

This statement is false, therefore option d is incorrect.

a traveler has 7 pieces of luggage . how many ways can the traveler select 3 pieces of luggage for a trip
7nadin3 [17]
Well, you could assign a letter to each piece of luggage like so...

A, B, C, D, E, F, G

What you could then do is set it against a table (a configuration table to be precise) with the same letters, and repeat the process again. If the order of these pieces of luggage also has to be taken into account, you'll end up with more configurations.

My answer and workings are below...

35 arrangements without order taken into consideration, because there are 35 ways in which to select 3 objects from the 7 objects.

210 arrangements (35 x 6) when order is taken into consideration.

*There are 6 ways to configure 3 letters.

Alternative way to solve the problem...

Produce Pascal's triangle. If you want to know how many ways in which you can choose 3 objects from 7, select (7 3) in Pascal's triangle which is equal to 35. Now, there are 6 ways in which to configure 3 objects if you are concerned about order.
