Answer:
principle or amount your account starts with. this could be a starting investment, or the starting about amount of a loan. interest, in its most simple form, is calculated as a percent of the principal. for example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then amount of interest you would pay would just pay would just be 5% of 100: $100(0.05)= $5. the total amount you would you would repay would repay would be $105, the original principal plus the interest.

Answer:
3/4
Step-by-step explanation:
to add fractions you have to let them have the same denominator or bottom number
so to make 3 and 12 the same number you would multiply 3 by 4
when multiplying the bottom number of a fraction by 4 you multiply the top too
so 2/3 becomes 8/12
then you can add
1/12 + 8/12 is 9/12
at the end you can simplify 9/12 into 3/4 by dividing the equation by 3/3 or both the top and bottom by 3
Answer:
the one that has the thingy by it
Step-by-step explanation:
First, find the expected value.
μ = 0 (0.28) + 1 (0.37) + 2 (0.22) + 3 (0.08) + 4 (0.05)
μ = 1.25
Now find the standard deviation.
σ² = (0−1.25)² (0.28) + (1−1.25)² (0.37) + (2−1.25)² (0.22) + (3−1.25)² (0.08) + (4−1.25)² (0.05)
σ² = 1.2075
σ = 1.099
If we were to select many boxes of bulbs randomly, the number of defective bulbs would typically vary about 1.099 from the mean.
