B is your answer I just took the assignment quiz.
Answer:
Step-by-step explanation:
Crickets can jump with a vertical velocity of up to 14 ft/s
General equation is
Where v0 is the initial velocity
h0 is the initial height
velocity is 14 ft/s
initial height is not given so h0=0
x = -4 ± 2√3
B
idk
19
19 is the answer I think so
The numbers less than 50 (A) = 4
Total numbers (S) = 14
Probability students below 50 = 4÷14
That is the correct answer of it.
