Minus 36 from each one you can do it on a calculator:)
The data distribution is positively skewed
<span>3 of the 20 toothbrushes are defective, so the initial probability of selecting a defective toothbrush on the first try is 3/20. After that, there will be 2 defective toothbrushes in the remaining 19, so the probability of selecting one of those on the 2nd try will be 2/19. To get the probability of those two events happening sequentially, we multiply the two probabilities. Thus (3/20)*(2/19) = 6/380 = 0.0157, or about 1.6%.</span>
The answer is 52.80 because the tip is $8.80 and 44.00+8.80=52.80
Hello,
So we can first assign HD videos and classic videos to specific variables, x is HD videos and y is classic videos.
Fiona bought 5 HD videos, and 2 classic videos for 31 dollars.
5x + 2y = 31
Iliana bought 3 HD videos and 5 classic videos for 30 dollars.
3x + 5y = 30
Therefore, the final answer is choice D, 5x + 2y = 31 and 3x + 5y = 30.
