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>

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.
