Step-by-step explanation:
Mean = Sum of all values/ total no of values
There are four numbers .
Mean =
Taxable income = adjusted income − (deductions + allowance for exemptions) With deductions, you can itemize deductions or use the standard deduction.
Answer:
The probability of rolling an even number would be or 50%.
Step-by-step explanation:
A standard number cube has 6 sides that features numbers 1 to 6 on each side. Since there are three even numbers (2, 4, 6) total on the sides of the number cube, that means the theoretical probability of rolling an even number would be , which simplifies to or 50%.
There's enough arithmetic involved in this that it is convenient to let a machine solver of some sort figure it out. Most graphing or scientific calculators will work this problem for you (consult the manual for yours). If you insist on doing it by hand, you must compute several average values:
• a1 = the average of sleep hours (h)
• a2 = the average of test scores (%)
• a3 = the average of the product of sleep hours and test scores (h×%)
• a4 = the average of the square of sleep hours (h×h)
a) The equation of your best-fit (least-squared-error) line is then
% = (a3 - (a1×a2))/(a4 - (a1)²)×(h - a1) + a2In numbers, this is
% = 6.33333h + 38.6875b) For h=8, the equation gives
6.33333×8 + 38.6875 ≈
89.4
