Since the y-intercept is -3, plot a point at -3 on the y-axis (vertical). Then, continue to make points by following the slope down.
Remember, slope is written as y/x
A slope of -1/2 could be interpreted as -1 over 2. So, each time you move down 1 space, you move to the right 2 spaces.
So, following the slope down, you'd plot another point at (2,-4). Then, another at (4,-5), and so on. Understand?

A radio station claims that the amount of advertising per hour of broadcast time has an average of 10 minutes and a standard dev

podryga [215]

Answer: -0.36

Step-by-step explanation:

Given: Mean : $\mu=10\text{ minutes}$

Standard deviation : $\sigma=5\text{ minutes}$

We know that the formula to calculate the z-score is given by :-

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

For x=8.2 minutes, we have

$z=\dfrac{8.2-10}{5}=0.36$

Hence, the z-score for this amount of advertising time = -0.36

What is the area of the trapezoid above?

icang [17]

Answer:

26 square meters (the first option)

Step-by-step explanation:

The area of a trapezoid is (b1+b2)/2*h.

b1=one of the bases (one of the bases that are parallel to each other)

b2= the other base (that is parallel to base 1)

h=height

In this picture, b1=5, b2=8, h=4

So, the area is

(5+8)/2*4

=13/2*4

=6.5*4

= 26 square meters
