Answer:
Volume of the prism = 140 cubic inches.
Step-by-step explanation:
The edge length of the cube is 1/2 inches.
The volume of the cube is given by
![\text{Volume}=(\text{edge})^3\\\\V=(1/2)^3\\\\V=0.125](https://tex.z-dn.net/?f=%5Ctext%7BVolume%7D%3D%28%5Ctext%7Bedge%7D%29%5E3%5C%5C%5C%5CV%3D%281%2F2%29%5E3%5C%5C%5C%5CV%3D0.125)
Now, it has been given that there are 1120 cube is completely filled in the prism. Hence, we have to the multiply the volume by 1120.
Volume of the prism = 1120 × 0.125
Volume of the prism = 140 cubic inches.
Here, number of bulletin board = 1
Artwork = 2/5 th, & math papers = 1/5
So, it would be: 1/5 + 2/5 = 3/5
In short, Your Answer would be 3/5 or 0.60
Hope this helps!
Hi!
One deck of card has 52 cards, and in every deck there are 4 queens.
We will find the probability of pulling out the queen from the deck by diving the number of queens by the number of cards in the deck, like this:
4/52 = 1/13
Hope this helps!
Answer:
Sorry im not good at math
Answer:
This can be solved by using the empirical rule for a normal distribution.
Step-by-step explanation:
A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:
68 + 16 = 84%.
B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:
5/2 = 2.5%
C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:
16%.
