Answer:
A
Step-by-step explanation:
Carlos' score was 2 standard deviations from the mean, so his z-score was 2.0. You can either use the empirical 68-95-98.5 rule, or you can plug it into your calculator as <u>normalcdf(-999, 2) = .977</u>
So 97.7% of people had a score lower than Carlos!
.977 * 1.5 million = 1,465,500 people
Answer:
Step-by-step explanation:
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
Bringing like terms on one side
3 + 9 = 4.5x - 1. 5x
12 = 3x
12/3 = x
4 = x
Answer: Hey there, your answer is 1/12
Step-by-step explanation: Steps to solve (steps will be in numerical order)
1. Find the lcd of the fractions, and the lcd for both problems will be 12.
2. To rewrite you have to multiply the numerator and denominator by three since the lcd is 12. So you're new fraction will be . For the second fraction, since the lcd is 12 you will multiply the numerator and denominator by 4. You're new fraction will be .
3. Since the problem contains the math keyword "Further", you automatically know you have to subtract, now subtract - . First, start of by subtracting the numerators, so subtract 9-8=1 , remember the denominators will always stay the same.
In conclusion, you're answer will be , so Isabel lives farther away from Janet.
Hope This Helps :)
