D is the correct answer !
Probability = favorable event/total number of events
number of blue=6
total number of possibilities = 15
then P(blue)=6/15 = 2/5 =0.40
W replace it again (so the total number is always 15) & we draw a Red:
P(Red) = 5/15 =1/3 = 0.33
Answer:
x=-3, y=-7. (-3, -7).
Step-by-step explanation:
x-5y=32
2x-9y=57
---------------
x=5y+32
2(5y+32)-9y=57
10y+64-9y=57
10y-9y=57-64
y=-7
x-5(-7)=32
x+35=32
x=32-35
x=-3
Answer:
Force, F = 68.93 pounds
Step-by-step explanation:
Given that,
Mass of the astronaut, m = 80.70 kg
Acceleration due to gravity on Mars,
The force acting on him is given by using second law of motion as :
F = 306.66 N
Since, 1 newton = 0.224 pound
F = 306.66 N = 68.93 pounds
So, 68.93 pounds force she exerts on the martian surface. Hence, this is the required solution.
