Answer:
9/10
30%
Step-by-step explanation:
Only in trial number 4, there is just one correct answer. In all other 9 trials at least 2 answers were correct. So the probability is 9 out of 10 trials give a winning outcome, in short, 9/10.
Giving birth to three males first, is true in 3 out of 10 trials. You can count the total numbers of Y's in the last column.
So 3/10 which is 0.3 which is the same as 30%.
So, we know the sum of the first 17 terms is -170, thus S₁₇ = -170, and we also know the first term is 2, well
well, since the 17th term is that much, let's check what "d" is then anyway,
Answer:
Step-by-step explanation:
x-the original price
y- the discounted price
y= the original price - 25 % discounted from x = x- (.25*x) = x( 1-.25) = .75x
equation is y= .75x
The equation should only be in the first quadrant because the prices can only be positive numbers.
