Answer:

The y coordinate of the y-intercept is 0.

Step-by-step explanation:

Consider the provided function.

$y=x^3-9x$

We need to find y coordinate of y intercept.

y intercepts are the point where the x value is 0 or the line cuts the y axis.

To find the y coordinates of y intercept, substitute x=0 in the provided equation.

$y=(0)^3-9(0)$

$y=0$

Therefore, the coordinates are (0,0)

Hence, the y coordinate of the y-intercept is 0

$y = x^{3} - 9x$
$y = 0^{3} - 9(0)$
$y = 0$

Which fraction is equivalent to that number? HELP NEEDED ASAP

solong [7]

Answer:

2/3

Step-by-step explanation:

Let n = the repeating, non-terminating number 0.666...

We now have n = 0.666666...

We want the number n in the form of a fraction.

Since only 1 digit repeats, the 6, use a 1 followed by 1 zero, which means the number 10. Now multiply both sides by 10 and write the original equation below it.

10n = 6.666666...

n = 0.666666...

Subtract the bottom equation from the top equation.

9n = 6

n = 6/9

n = 2/3

Find three points that belong to the graph and use them to sketch the graph of the equation: y = −3 −x

dalvyx [7]

Answer:

To find a point that belongs to the graph, you have to assume the value of one variable and compute the other one. For example, if x = 0, then y = -3 -0 = -3. Similarly:

x y

0 -3

1 -4

2 -5

To make the graph, locate the previous points on the coordinate plane and then draw the line that passes through them (see figure attached)

THIS IS THE COMPLETE QUESTION;

A school creates a histogram representing the individual travel times for students riding the bus to school. The histogram is right-skewed, and the mean time is 25 minutes.

Which statement best describes the possible value of the median time of students riding the bus to school?

The median time is less than 25 minutes.

The median time is exactly equal to 25 minutes.

The median time is approximately equal to 25 minutes.

The median time is greater than 25 minutes.

Answer;

The median time is less than 25 minutes

Step-by-step explanation

✓When the histogram is skewed right, it implies that the mean is greater than the median which means The median time is less than the mean.

This is as a result of few large values that drive as a result of skewed-right data

✓Skewness can be explained as measure of the asymmetry of a histogram When a histogram is symmetrical when it has a normal distribution, i.e when the same amount of data falls on both sides of the mean. Ahistogram has a normal distribution will have a skewness of 0.

✓the skewness can be explained in terms positive/right relationship:

√nonparametric skew implies that the mean is greater than the median, which means it is at the the right.

√A negative/left nonparametric skew can be explained as when the mean is < the median. I e it fall to the left .

Therefore, the median is less than 25 minutes

What is the simplified form of the equation 4/5n - 3/5 = 1/5n?

Oksi-84 [34.3K]

Answer:

n = 1 if you meant "(4/5)n - (3/5) = (1/5)n"

Step-by-step explanation:

There's some ambiguity here. Did you mean (4/5)n or did you

mean --------- ? Please use parentheses to eliminate this ambiguity.

I'm going to assume that you meant to type in (4/5)n - (3/5) = (1/5)n.

Then we have (3/5)n = 3/5, or n = 1
