Answer:
<u>Jamie's mistake</u>: The last term and not . Jamie multiply the signs incorrectly.
<u>Advice to avoid this mistake in the future</u>: Jamie should remember that when two negative numbers are multiplied, the result is a positive number.
Step-by-step explanation:
The correct procedure is the one shown below:
You can identify that the last term is actually and not , so Jamie multiply the signs incorrectly.
To avoid that mistake in the future, Jamie must remember the mulitplication of signs:
So when two negative numbers are multiplied, the result is a positive number.
Answer:
4.32% of the bottles will have more than 12.86 ounces.
Step-by-step explanation:
This is a normal distribution problem with
Mean = μ = 6 ounces
Standard deviation = σ = 0.4 ounce
Let the z-score of 4.32% of the bottles be z' and the corresponding ounces be x'
The z-score for any is the value minus the mean then divided by the standard deviation.
z' = (x' - μ)/σ
P(x > x') = P(z > z') = 0.0432
Using the normal distribution table
P(z > z') = 1 - P(z ≤ z') = 0.0432
P(z ≤ z') = 1 - 0.0432 = 0.9568
z' = 1.715
1.715 = (x' - 6)/0.4
x' - 6 = 4(1.715)
x' = 6 + 6.86 = 12.86 ounces.
4.32% of the bottles will have more than 12.86 ounces.

Answer:
4%
Step-by-step explanation:
The simple interest formula can be used.
I = Prt
where r is the annual rate and t is the number of years.
1/5 = 1·r·5
(1/5)/5 = r = 1/25 · 100% = 4%
The rate is 4%.
The variable is the number of hours Adi studied, the operation is addition, and the constant is 3. You can write the expression as h + 3 or 3 + h. To evaluate, substitute 8 in for the variable, h, and simplify. 8 plus 3 is 11. So Adi studied for 11 hours.
hope it helped !!!!!!!!!!1
