In correlation coefficient analysis, the value of r represents the degree of correlation. The closer the value is to 1, the more likely that a direct positive correlation exists. The closer the value is to -1, the more likely that a direct negative correlation exists. However, if the value of close to 0, then there is likely no or very low correlation. Therefore, the value representing low or no correlation in the given values is -0.001.

r-ruslan [8.4K]

Answer:

The point-slope equation of the line is $y = -2x +2$ or $2x+y = 2$

Solution:

Let us assume that the slope is m and the y intercept of the line is b

Hence, $y=m x+b$ --------- (i)

y intercept means we need to find the value of y when x is 0

Here the line passes through point (4,-6) and slope m = (-2)

Now putting the point (4,-6) in equation (i) we get,

$\Rightarrow-6 = m\times4 +b$

$\Rightarrow-6 = (-2)\times4 +b$

$\Rightarrow-6 = -8 +b$

$\Rightarrow-6+8 =b$

$\Rightarrow b = 2$

So, the equation of the line will be will be $y = -2x +2$ or $2x+y = 2$

A pile of 37 coins consists of nickels and dimes. The total value

tensa zangetsu [6.8K]

Answer:

25 dimes & 12 nickels

Step-by-step explanation:

Let there be "n" nickels and "d" dimes

Total, there are 37 of them, so we can write:

n + d = 37

Also, valueof nickel is 0.05 and value of dime is 0.10 (in dollars) and total value of these 37 coins is 3.10, so we can write:

0.05n + 0.10d = 3.10

Now we can write first equation as:

n + d = 37

n = 37 - d

Replace this into equation 2 and solve for d:

0.05n + 0.10d = 3.10

0.05(37 - d) + 0.10d = 3.10

1.85 - 0.05d + 0.10d = 3.10

0.05d = 3.10 - 1.85

0.05d = 1.25

d = 1.25/0.05

d = 25

Now, n = 37 - d, n = 37 - 25 = 12

So,

There are 25 dimes & 12 nickels
