Answer:
8 - i
General Formulas and Concepts:
<u>Algebra I</u>
<u>Algebra II</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(3 - 4i) + (5 + 3i)
<u>Step 2: Simplify</u>
- Combine like terms (Z): 8 - 4i + 3i
- Combine like terms (i): 8 - i
3(4m-2)-2(m+5)
Distribute.
12m-6-2m-10
12m-2m= 10m
-6-10= -16
10m-16
I hope this helps!

Answer:
0.8041 = 80.41% probability that a given battery will last between 2.3 and 3.6 years
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
A certain type of storage battery lasts, on average, 3.0 years with a standard deviation of 0.5 year
This means that 
What is the probability that a given battery will last between 2.3 and 3.6 years?
This is the p-value of Z when X = 3.6 subtracted by the p-value of Z when X = 2.3. So
X = 3.6



has a p-value of 0.8849
X = 2.3



has a p-value of 0.0808
0.8849 - 0.0808 = 0.8041
0.8041 = 80.41% probability that a given battery will last between 2.3 and 3.6 years
