Answer:
42cm^3
Step-by-step explanation:
Given data
Area of base= 14 square centimeters,
Height= 3 centimeters
Volume = Area* Height
Volume= 14*3
Volume= 42 cm^3
Hence the volume of the prism is 42cm^3
The correct answer is 43.75
Answer:
480
Step-by-step explanation:
If a person blinks every 3 minutes, there is 60 minutes in 1 hour. So, multiply 60 by 24 (hours a day), 60 x 24 = 1440 minutes.
1440/3 = 480
<h3>
Answer: 9/100</h3>
========================================================
Explanation:
There are 3 pink marbles out of 10 total (we can see that 2 yellow + 3 pink + 5 blue = 10 total)
The fraction 3/10 represents the probability of pulling out a pink marble at random. Since the first one is put back, this means the fraction 3/10 stays the same on the second draw as well.
We use the idea mentioned in the hint to multiply the fractions:
(3/10)*(3/10) = (3*3)/(10*10) = 9/100
The probability of pulling two pink marbles in a row is 9/100, where the first marble is put back.
Effectively, if you were given 100 tries at doing this, you should expect about 9 of those times you get 2 pink marbles in a row.
Answer:
1/2
Step-by-step explanation:
A sample space is a collection or a set of possible outcomes of a random experiment.
I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.
To find the probability that the total showing is greater than 9, simply identify the number of values in the sample space that are greater than 9.
(I have highlighted these in yellow).
Therefore, P(X>9) = 8/16 = 1/2
