The cup was filled at a constant rate. It started empty. After 2 seconds, it held 70 cm^3 of water.

Mathematics

nydimaria [60]3 years ago
8 0

Answer:

About 90%

Step-by-step explanation:

If the cup was filled at a constant rate, then the cup fills at 70/2=35 cubic centimeters per second. The formula for the volume of a cone is \frac{1}{3} \pi r^2 h, or in this case \frac{112}{3}\pi cubic centimeters. After 3 seconds, the cup would have 35*3=105 cubic centimeters of water inside of it, or about 89.52% which rounds to 90%. Hope this helps!

Alika [10]

Answer:

P(170

And we can find the probability with this difference:

P(-0.6

And using the normal standard table or excel we got:

P(-0.6

And the best answer would be:

0.3811

Step-by-step explanation:

Let X the random variable that represent the ratings of a population, and for this case we know the distribution for X is given by:

X \sim N(200,50)  

Where \mu=200 and \sigma=50

We are interested on this probability

P(170

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

Using the z score we got:

P(170

And we can find the probability with this difference:

P(-0.6

And using the normal standard table or excel we got:

P(-0.6

And the best answer would be:

0.3811
