Answer:
3g = x - 2
Step-by-step explanation:
x = 3g + 2
3g + 2 = x
3g + 2 - 2 = x - 2
3g = x - 2
Answer:
2 1/2
Step-by-step explanation:
Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.
4 3/4
4 * 4 + 3 = 19
19/4
2 1/4
2 * 4 + 1 = 9
9/4
Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.
19/4 - 9/4 = 10/4
Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:
4 * 2 = 8
10 - 8 = 2
2 1/2
The answer is Compound Quarterly
The sample mean is approximately normally distributed with mean $75.00 and standard deviation $15.00/sqrt(64)
1) The z-score for $70.00 is
(70 - 75)/(15/8) = -2.66667 = -2.7 to the nearest tenth.
2) The probability corresponding to this z-score is 0.0035 (use standard normal tables), or 0.35%, which rounded to tenths is 0.4%
I will leave the rest to you. The instruction in step 5 is wrong; you do not add the probabilities from steps 1 and 3. (If you do add them, you will get 1, which is clearly the wrong answer.)
P(70 < sample mean < 80) = P(sample mean < 80) - P(sample mean < 70)
so you should subtract the result in step 1 from the result in step 3.
The correct answer is 0.993, or 99.3%
