Probability works for any given number, so we will assume there are 100 students. Of those 100, 85 of them studied. Since 75% of 85 students passed, we will multiply 85 by 0.75. This gives us 60. So of the students who studied, 60 of them passed. Of the 15 students that didn’t study, 30 percent passed. So we multiply 15 by 0.3. This gives us 4.5 students. Add up 60 and 4.5, and you get 64.5. The probability of passing is 64.5%. If you want to round up, it would be 65%. If you want to round down, it would be 64%. But the most precise answer is 64.5%.
Type of slope is if it is negative or positive so looking from left to right does the line go down or up. For 1 it is positive but for 3 it is a negative slope. And triangle y(delta y)/ delta x is basically y2-y1/x2-x1. So pick two point and plug In the numbers. So slope of number one is 1/2 ( you could also count the rise over run from one point to another too)
Answer:
he should take 29.4 mL a day
Step-by-step explanation:
Divide the given angle by 360, then multiply by 2 x radius x PI:
85/360 x (2 x 14 x PI)
85/360 x 87.96459 = 20.769 ( Round answer as needed)
Or if needed in terms of pi : 6.61PI
You did not say how the answer needed to be rounded.
