8 0

Answer:

A. A

Step-by-step explanation:

In a scatter plot, the value of correlation coefficient is represented by values between -1 to 1. The closer any value of correlation coefficient is to "0", the farther the data points on a scatter plot are from the line of best fit.

Invariably, considering the scatter plot shown in the graph above, the point that will MOST DECREASE the value of correlation coefficient is point A. This is because, if point A is added in the scatter plot, it will cause the value of correlation coefficient to be closer to 0, as point A is the farthest from the line of best fit compared to other points. This will make the data points more spread out and less clustered along the line of best fit.

Handsome jack is buying a pony mad of diamonds. The price of the pony is p dollars and jack also has pay 25% diamond pony tax. H
Leona [35]

Answer:

5/4 P dollars

Step-by-step explanation:

Given that,

price of pony =  P

Tax which is to added in the total price of pony = 25% of pony price

so, now total price of pony including its tax = P + 25%P

                                                                        =  P + 25/100 P

                                                                        =  P + 1/4 P

                                                                        = 5/4 P dollars

                                                                        =  1.25 P dollars

What's the error? Jerry says that a cube with edges that measure 10 cm has a volume that is twice as much as a cube with sides t
disa [49]
The quick way to dispute something like this is to simply do the calculation and then create a ratio. 

Cube One (Large Cube)
The formula for a cube is V = e^3 
e = the measurement of an edge. In this case.
e = 10 cm
V = e^3
V = 10^3 = 10*10*10
V = 1000 cm^3

Cube 2 (Small Cube)
V = e^3
e = 5 cm
V = 5*5*5
V = 125 cm^3

Ratio
Large Cube / Small Cube = 1000 / 125 = 8/1.

The difference in size is 8 to 1 not 2 to 1.

Explanation
He's right if he sticks to one side. The ratio of one side of the large cube to the small one is 2 to 1. But once you put that into the formula for volume, three sides are multiplied together and that 2 shows up everytime you multiply the sides together.
