What is the mode of these numbers: 10, 13, 800, 24 and 13
OverLord2011 [107]
A mode is the number that appears the most in a set of numbers. (I'm going to put the numbers in order before I solve this) 

10, 13, 13, 24, 800

The answer is 13, because it appears more than any of the other numbers. :)

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

7. If x can be any number, how many solutions are there for the equation? y = 7x – 1 * A. There are two solutions because there
Hitman42 [59]
For the function y = 7x - 1, if you state that the domain(or all the numbers you can substitute in for "x") of that function is the set of all real numbers, then you can assume that there will be an infinite number of solutions for the function.

In other words, if you substitute any real number in for "x" you will find that you will get a corresponding value for "y".  In fact, these "pairs" of corresponding values of x and y are called ordered pairs and represent the various solutions of the equation.  

Your response should be choice D:

Find the area of the shape shown below.
sveticcg [70]

Answer:

A = 15u²

Step-by-step explanation:

Area of a Trapezoid Formula:

\frac{h}{2}*(b_1+b_2)

Plug in our values (h = 3, b1 =  7, b2 = 3)

\frac{3}{2}*(7+3)

Now we evaluate

\frac{3}{2}*(10)

\frac{30}{2} = 15
