Nina [5.8K]3 years ago
5 0
Pearson mode skewness, also called Pearson's first coefficient of skewness, is a way to figure out the skewness of a distribution. The mean, mode and median can be used to figure out if you have a positively or negatively skewed distribution. If the mean is greater than the mode, the distribution is positively skewed.

Answer:

y = 120x

Step-by-step explanation:

y=mx + b is what we need where m is the slope and b is the y-intercept.

the train travels at about 120km/hour, thus the slope is 120.

y= 120x +b. to find the y intercept plug in any coordinate.

240 = 120(2) +b. you find that the y-intercept is 0.

final equation: y= 120x

Free_Kalibri [48]

Answer:

2 : 5

Step-by-step explanation:

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

We are to determine the ratio of dimes to nickels

total sum of nickels = 3 + 12 = 15

total sum of dimes = 4 + 2 = 6

6 : 15

three can divide each of the numbers

2 : 5

Yvonne is solving the quadratic equation 6x2 + 24x + 7 = 0 by completing the square. Her first four steps are shown in the table
vladimir1956 [14]

The step in which Yvonne first makes an error while solving the quadratic equation by completing the square in step 1.

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation in which the highest power of the variable is two.

Yvonne is solving the quadratic equation, which is,

6x² +24x +7 =0

He is solving the above equation by completing the square.

The first step to solving this quadratic equation by completing the square is, Take the constant value 7 at the opposite side of the equation as,

6x² +24x = -7

Here, the number seven was a positive number, which we have changed to negative because this number brings the other side of the equation.

In the image attached below, the first step of  the Yvonne while solving the equation by completing the square is,

6x² +24x = 7

Here, Yvonne does not change the sign of the number 7 while taking it to another side of the equation.

Hence, the step in which Yvonne first makes an error while solving the quadratic equation by completing the square is step 1.

The table is attached with the answer below
