The given study is observational study

To gauge how strongly two variables are related to one another, correlation coefficients are used.

A statistical indicator of the strength of the association between the relative movements of two variables is the correlation coefficient. The values are in the -1.0 to 1.0 range. There was a measurement error in the correlation if the estimated value was larger than 1.0 or lower than -1.0. Perfect negative correlation is shown by a correlation of -1.0, and perfect positive correlation is shown by a correlation of 1.0. A correlation of 0.0 indicates that there is no linear link between the two variables' movements. Finance and investing can benefit from the usage of correlation statistics.

Alexander is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Ale
andrezito [222]

Answer:

2 three points shots and 4 two points shots

Step-by-step explanation:

Let x be the number of three points shots.

Alexander  made twice as many two points shots as three points shots, so the number of two points shots is 2x.

Amount earned in three points shots =3\cdot x

Amount earned in two points shots =2\cdot (2x)=4x

Total score =3x+4x=7x

Alexander scores a total of 14 points, then

7x=14\\ \\x=2\\ \\2x=2\cdot 2=4

Find the sum of the first 5,000 odd numbers
Nata [24]

Step-by-step explanation:

this is an arithmetic sequence :

a1 = 1

an = an-1 + 2 = a1 + (n-1)×2

the sum of n terms of an arithmetic sequence is

S = n×(a1 + an)/2

n = 5000

an = a1 + 4999×2 = 9999

S = 5000×(1 + 9999)/2 = 5000×5000 = 25,000,000

6x^2-15x+8x-20

Collect like terms:

6x^2+(-15x+8x)-20

Simplify:

6x^2-7x-20
