Answer:
-3
Step-by-step explanation:
X+-4x=3
The first step will be to add 6 on both sides
Answer:
20 riders can ride per minute.
Step-by-step explanation:
The picture says to divide to find the number of riders. If we apply this here, we can see that 1200 ÷ 60 is 20.
The reasoning behind this is:
There are 60 minutes in an hour.
If the park ride lasts a minute, then the ride can have 60 rides per hour.
The question states that the ride can have up to 1200 riders per hour, so you need to divide 1200 by 60.
1200 ÷ 60 = 20.
Answer:
The answer is "This direct variant (-4,2) is part of it".
Step-by-step explanation:
The equation expresses its direct variation relation
![y = mx ........ (1)](https://tex.z-dn.net/?f=y%20%3D%20mx%20........%20%281%29)
Where x and y vary directly, and k vary continuously.
Now so the point (4,-2) is in the direct relation of variation, so from equation (1) we are given,![-2 = 4m](https://tex.z-dn.net/?f=-2%20%3D%204m)
![\to m=-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cto%20m%3D-%5Cfrac%7B1%7D%7B2%7D)
The equation (1) is therefore converted into
![\to y=-\frac{1}{2}x \\\\\to x + 2y = 0 ......... (2)](https://tex.z-dn.net/?f=%5Cto%20y%3D-%5Cfrac%7B1%7D%7B2%7Dx%20%5C%5C%5C%5C%5Cto%20x%20%2B%202y%20%3D%200%20.........%20%282%29)
Then only the point (-4,2) satisfies the connection with the four possibilities (2). Therefore (-4,2) is a direct variant of this.
Answer:
C) Mean, Skewed.
Step-by-step explanation:
The mean is easily influenced by outliers in a distribution. So if a Distribution of scores is skewed, then it will mislead the readers. In a skew distribution, either positive or negative, the Median will turn to be the central value. Usually, the mean is used besides other statistical parameters.
In a Normal distribution, the mean is right in the middle, symmetrically dividing the "bell shape" curve. The Mean, in this case, coincides with the mode, and the Median.
On the other hand, the Median is way more trustable central tendency measure, more resistant to outliers. So in a Skewed distribution, a Median is preferred over the Mean and use alongside the Mode.
