Answer:
5/24 or 20.8%
Step-by-step explanation:
Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2
Probability that the 8th grader is a boy = 5/(5+7) = 5/12
Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%
Answer:
The side lengths are not congruent. Evidence: Becuase the line shows that one is higher. None of the sides are parallel. Evidence: none of the lines of the shape are on the exact same line. No the adjacent sides are not perpendicular. Evidence: They are crooked and you can tell becuase of how the shape is on the line. The most specific shape is a rhombus. A rhombus is a crooked square. This isn't a perfect rhombus.
Step-by-step explanation:
20% because you’d take 1/5 of 100 to find the percentage
The given function is
According to this function, the starting height of the rocket is 20 feet because that's the initial condition of the problem stated by the independent term.
Additionally, we find the maximum height by calculating the vertex of the function V(h,k).
Where a = -16 and b = 300.
Then, we find k by evaluating the function
Hence, the maximum height is 1426.25 feet.
At last, to know the time need to hit the ground, we just use h=9.375 and we multiply it by 2
Hence, the rocket hits the ground after 18.75 seconds.
