Which statement best illustrates using the vertical line test to determine if the graph below is a function of x? The graph is n

GuDViN [60]

Answer:

The graph is not a function of x because the line x = 0 intersects the graph at two points.

Step-by-step explanation:

This graph is not a function because it fails the vertical line test, since several vertical lines would intersect the graph at 2 points.

This answer choice is correct, as the line x = 0 intersects the graph at 2 points, (0, 2) and (0, -2).

The time college students spend on the internet follows a Normal distribution. At Johnson University, the mean time is 5 hrs wit

netineya [11]

Answer:

The probability that the average time 100 random students on campus will spend more than 5 hours on the internet is 0.5

Step-by-step explanation:

We are given that . At Johnson University, the mean time is 5 hrs with a standard deviation of 1.2 hrs.

Mean = $\mu = 5 hours$

Standard deviation = $\sigma = 1.2 hours$

We are supposed to find the probability that the average time 100 random students on campus will spend more than 5 hours on the internet i.e. P(X>5)

$Z=\frac{x-\mu}{\sigma}$

$Z=\frac{5-5}{1.2}$

Z=0

P(X>5)=1-P(X<5)=1-P(Z<0)=1-0.5=0.5

Hence the probability that the average time 100 random students on campus will spend more than 5 hours on the internet is 0.5

What is an equation of the line that passes through the point (-5,-3)(−5,−3) and is parallel to the line 3x+5y=15

Sunny_sXe [5.5K]

Answer:

y = -3/5x - 6 or 3x + 5y = -30

Step-by-step explanation:

Given line:

3x + 5y = 15

Converting into slope-intercept form:

3x + 5y = 15
5y = - 3x + 15
y = -3/5x + 3

Parallel lines have the same slope, so the parallel line will be:

y = -3/5x + b

Using given point (-5, -3) finding the y-intercept:

-3 = -3/5(-5) + b
-3 = 3 + b
b = -3 - 3
b = -6

So the line is:

y = -3/5x - 6

Or converted into standard form:

y = - 3/5x - 6
3/5x + y = -6
3x + 5y = -30

Multiply and put in simplest form: 2x(4x+5) ANSWER= 8x^2+10x Why is 8x squared?

Ksivusya [100]

Because you're multiplying $2x$ by $4x$ . $2*4$ is $8$ , $x*x$ is $x^2[tex], and [tex]8*x^2$ is $8^2$ . Since you're multiplying them all together, it doesn't matter what order you multiply them in. For example, $2*x=2x$ , $x*4=4x$ , and [2x*4x=8x^2[/tex] (but that's just the same.)

Hope that helps! :)

the distance from the center of a round table top to the edge of the table top is 4 feet what's the area of the table top

jekas [21]

4ft is the radius of the circle (round table)
Use this formula to find the area of the circle:
Area = $\pi r$ ²
so 4²
4² = 16
16 $\pi$ is your answer <3
