Answer:
Contributions to a 401(k) are pre-tax, meaning they are deposited before your income taxes are deducted from your paycheck. However, when in retirement, withdrawals are taxed at your then-current income tax rate. Conversely, there is no tax savings or deduction for contributions to a Roth IRA
There is nothing to do with it. If it gives you x=# or y=# then you can plug it in, but otherwise, this is the simplest way to write this equation.
If you want to go further, you can figure out that
y= 7-x
but that's about it.
Answer:
90 possible outcomes.
Step-by-step explanation:
In order to find the total number of combinations possible you simply need to multiply the total number of each options with one another. For example, the number of options in each category are the following
types: 5
toppings: 6
size: 3 (small, medium, large)
Now we simply need to multiply all three of these numbers together to find the total number of possible outcomes.
5 * 6 * 3 = 90 possible outcomes.
Answer: The 95% confidence interval would be (4.57,4.63).
Step-by-step explanation:
Since we have given that
N = 1000 typical loans
Mean = 4.6 errors
Standard deviation = 0.5 errors
At 95% confidence, z = 1.96
So, 95% confidence interval on the true mean error rate is given by
Hence, the 95% confidence interval would be (4.57,4.63).
Answer:
The correct option is;
c. Symmetrical without outliers
Step-by-step explanation:
Here we have the measure of central tendency given as follows
Mean, μ = Σx/n
Mean absolute deviation,
Therefore, where both measures of central tendency and variability accurately describes the data then
For the mean, Σx/n to describe the data, it must be without outliers
For the mean absolute deviation, , to describe the data it must be symmetrical.
