Answer:
Amy should not use her previous luck of rolling a 3 four times because theoretical probability remains the same even after an event favoring one side has occurred by chance.
Step-by-step explanation:
Assuming that this number cube has 6 sides, there is only 1 side that has a 3 on it. For this reason, every time the cube is rolled there is a 1 in 6 chance that the number will be a 3. If she rolls the number cube 240 times, 1 out of 6 rolls would be a 3. This means that 240/6 equals the number of times she would get a 3. Moreover, Amy would role the number 3 on 40 different times after rolling the cube for a total of 240.
Answer:
<h3> 552.640in³/s</h3>
Step-by-step explanation:
Volume of a cylinder is expressed as;
dV/dr = 2πrh
dV/dr = 2π(4)(6)
dV/dr = 48(3.14)
dV/dr = 150.72in³/m
dV/dh = πr²
dV/dh = 3.14(4)²
dV/dh = 50.24
Given
dh/dt = 5in/s
dr/dt = 2in/s
Substitute into the dV/dt
dV/dt = 150.72(2)+50.24(5)
dV/dt = 301.44 + 251.2
dV/dt= 552.640in³/s
The volume is changing at the rate of 552.640in³/s
