The best answer to the statistics question above would be letter A. The r-value that represents the strongest negative correlation among the given choices would be -0.7. This is because the magnitude of the correlation ranges from .7 to .9 which indicates a strong correlation. The negative sign connotes the negative relationship.

Montano1993 [528]

Answer:

<u>c. no solution</u>

Step-by-step explanation:

This system of equations has no solution because when graphed, the lines are parallel to each other. Meaning they will never intersect. Since they will never intersect, there are no solutions.

Long division 12p^5+20p^4+18p^2+45p+25/3p+5

lina2011 [118]

Answer:

$4p^4+6p+5$

Step-by-step explanation:

Given

$\frac{12p^5+20p^4+18p^2+45^p+25}{3p+5}$

Step 1:

Now Dividing the above Equation our first quotient will be $4p^4$ and First remainder will be $18p^2+45p$

Step 2:

Now Dividing the First remainder $18p^2+45p$ with $3p+5$

now our second Quotient will be $4p^4+6p$ and Second remainder will be $15p+25$

Step 3:

Now Dividing Second remainder $15p+25$ with $3p+5$

now our third Quotient will be $4p^4+6p +5$ and Remainder will be 0.

$\therefore$ Our Final Answer is $4p^4+6p +5$ with remainder 0

The Richter Scale gives a mathematical model for the magnitude of an earthquake in terms of the ratio of the amplitude of an ear

Alexeev081 [22]

Answer:

The magnitude of the claimed earthquake would be 13.67.

Step-by-step explanation:

The 1906 earthquake had a intensity of A and a magnitude of 7.8.

S is going to have the same value, so i am going to write as 1. So:

$\log{A} = 7.8$

$A = 10^{7.8}$

$A = 63095734.448$

Many pundits claim that the worst is yet to come, with an earthquake 748,180 times as intense as the 1906 earthquake ready to hit San Francisco.

So $A = 748180*63095734.448$

So

$R = \log{A} = \log{748180*63095734.448} = 13.67$

The magnitude of the claimed earthquake would be 13.67.
