Multiply the amount each one saves by the number of weeks they save:
Julia: $30 x 5 weeks = $150 total.
George : $45 x 5 weeks = $225 total.
Answer:
The correct option is;
Non of the above
Step-by-step explanation:
Option A is correct when a + b·i is a complex number, the real part = a and the imaginary part = b
Option B.) For the complex number, a + b·i, a and b are real number
Option C) When a number, a + b·i is a complex number, then b ≠ 0
Option D) Whereby real numbers are numbers of the form a + b·i, where b = 0, therefore, a real number is a complex number with the imaginary part = 0 and every real number is a complex number.
For this case we have the following system of equations:
To solve, we add both equations:
We find the value of "x":
The solution is (-4,10)
ANswer:
Option C
Well, there are 13 places that each horse can place. That means the first place has 13 options, second place has 12 options, third place has 11 options, etc. Though, we only care up to fourth place. When doing probability, we're multiplying in this case. So, here's the process:
How many ways all the horses can place = 13! = 6227020800
How many ways the first four places can place = 13*12*11*10 = 17160
Divide the second by the first and multiply by 100 for the probability as a percent:
(17160/6227020800)*100% ≈ <span>0.00027557319%

The answer is B. x = 65, y = 10.
