Answer:
Below in bold.
Step-by-step explanation:
Total number of marbles = 3+4+5 = 12
P(white, red) = 4/12 * 3/11
= 12/132
= 1/11,
P(blue, white, red) = 5/12 * 4/11* 3/10
= 60/1320
= 6/132
= 1/22.
Answer: 2.8 x 10^-3
Step-by-step explanation: Because 10^-3 moves the decimal backwards 3 times

Sorry i dont know the axis of symmetry but you can get the sketch at the graphing calculator desmos
Answer: 40.96 meters.
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the trigonometric functions.
sin α = opposite side / hypotenuse
Where α is the angle of elevation of the string to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the string), and the opposite side (x) is the length of the kite above the ground
Replacing with the values given:
sin 55 = x/ 50
Solving for x
sin55 (50) =x
x= 40.96 m
