Can a set of data having two modes have two points of central tendency

Fynjy0 [20]

Answer:

The Measure of Central Tendency are

1. Mean

2. Median and Quartiles

3. Mode

4. Geometric Mean

5. Harmonic Mean

→When all the five Measure of Dispersion are Same, it means the two data sets have Identical Variate.

→Now consider the two data sets,

A=3,4,4,5

B=1,4,4,7

Both the Data set have , same mean, median, and Mode,which is equal to 4.

→When you will consider, First three as Measure of central tendency ,then it becomes incorrect statement ,that Data Set are same.

Two cars leave at the same time from points A and B, the distance between them is 280 km. If the cars meet each other, they’ll m

kykrilka [37]

Set up the following equations:

$2x + 2y = 280$

$14x - 14y = 280$

x represents car A's speed, and y represents car B's speed.

We'll use elimination to solve this system of equations. Multiply the first equation by 7:

$(2x + 2y = 280) * 7 = 14x + 14y = 1960$

$14x - 14y = 280$

Combine both equations:

$28x = 2240$

Divide both sides by 28 to get x by itself:

$x = 80$

The speed of car A is 80 mph.

Since we now know the value of one of the variables, we can plug it into the first equation:

$2(80) + 2y = 280$

$160 + 2y = 280$

Subtract 160 from both sides.

$2y = 120$

Divide both sides by 2 to get y by itself:

$y = 60$

The speed of car B is 60 mph.

John paid 5% sales tax on his television, which cost $769 before taxes. What did the television cost in total?

zheka24 [161]

For this case we can make the following rule of three:
$ 769 ---------> 100%
x --------------> 105%
From here, we clear the value of x.
We have then:
x = (105/100) * (769)
x = 807.45 $
Answer:
the television did cost 807.45 $ in total

I'm going to assume that the glasses' units are centimeters, so the volume of Glass 2, the cone is 78.28, that would mean the area of the other glass, Glass 1 is 121.72. Since I know the Diameter, Radius, and Area of the Glass, I can just use it to find out the height, it equates to 4.04 as the height, which is shown there as one of the answers.
