The probability that a student is in seventh grade, given that he/she is dropped off by parents is <u>option C)</u> 0.22
<u>Step-by-step explanation</u>:
- The total probability of students in 7th grade = 0.56
- The probability of 7th grade students dropped by parents = 0.12
P(student is in 7th grade student is in seventh grade) = P(students in 7th grade) / P(7th grade students dropped by parents).
⇒ 0.12/0.56
⇒ 0.22
A (-6, -4)
B (3, 4)
C (6, -1)
Answer: Sometimes
Step-by-step explanation:
This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas
Answer: x=21
Step-by-step explanation:
To solve for x you must first combine you like terms on each side of the equal sign. So you problem will become 8x+1=22+7x. Then get your x on one side and your numbers on the other by taking the one away from the right side and 1 away from 22. Then take away 7 from the left side to cancel it out. Then take 7x away from 8x to leave you with x. making your answer x=21
