Answer:
1/10
Step-by-step explanation:
First, find the probability of choosing the red pen:
There are 6 total pens and 3 are red, so the probability will be 3/6
This can be simplified to 1/2
Then, find the probability of choosing a blue pen after not replacing the red one:
There are 5 total pens now, since we did not replace the red one.
There is only 1 blue pen, so the probability is 1/5
Then, multiply these 2 probabilities together:
1/2(1/5)
= 1/10
So, the probability is 1/10
Answer:
$0.03 per inch
Step-by-step explanation:
We need to convert 8 meters to inches first.
Unit ratio for meters to cm is:
So 8 meters is 800 cm
Now,
we need to convert 800 cm to inches
Unit ratio for cm to inches is:
So, 800 cm is :
inches
To get costing per inch, we divide total cost ($10) by the total number of inches (which is 314.96):
Rounded to nearest hundredth, $0.03 per inch
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above: The<span> regular octahedron with edges that are 2.1 inches.
2. Therefore, you must apply the formula for calculate the volume of a octahedron, which is:
V=(a^3</span>√2)/3
3. Therefore, you have:
V=((2.1 inches)^3√2)/3
V=178.30 inches^3
