"on the richter scale, the magnitude r of an earthquake can be measured by the intensity formula
r=log(i/io)
where i is the intensity of the shock wave. compare the intensity of an earthquake measuring 4.5 with the intensity of an earthquake measuring 3.0 on the richter scale. round your answer to the nearest whole number."
a) the earth quake measuring 4.5 on the richter scale is about 1.8 times more intense than an earthquake measuring 3.
b) the earth quake measuring 4.5 on the richter scale is about 32 times more intense than an earthquake measuring 3.
c) the earth quake measuring 4.5 on the richter scale is about 9 times more intense than an earthquake measuring 3.
the earth quake measuring 4.5 on the richter scale is about 63 times more intense than an earthquake measuring 3.

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:

Marco has $38.43 dollars in his checking account. his checking account is linked to his amazon music account so he can buy music. the songs he purchases cost $1.29. part 1: write an expression to describe the amount of money in his checking account in relationship to the number of songs he purchases. part 2: describe what the variable represents in this situation.

Me! i will mark brainliest! i don't get polynomials and all that other stuff. so this question is really hard. multiply and simplify.(x - 4) (x^2 – 5x – 6)show your
