Answer: The volume is 33 cubic centimeters.
Step-by-step explanation:
First find the volume of the square pyramid on top of the cube. To find the volume of the square pyramid you use the volume a^2*h/3 a is the side length of the base of the square pyramid and h is the height all divide by 3.
So we can say that the side length of the base of the square pyramid is 3 because it has the same side length base as the cube.
V= 3^2 * 2 /3
V= 9 * 2 /3
V= 18/3
v= 6
So the volume of the square pyramid is 6 so now we need to find the volume of the cube and add them together.
Volume of the a cube uses the formula s^3 where s is the side length.
V= 3^3
v= 3*3*3
v= 27
The volume of the cube is 27.
Add 6 and 27 to find the total volume.
6 +27 = 33
Answer: 0.965
Step-by-step explanation:
Given : Water use in the summer is normally distributed with
Let X be the random variable that represents the quantity of water required on a particular day.
Z-score : 
Now, the probability that a day requires more water than is stored in city reservoirs is given by:-
We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.
Answer:
A. 
Step-by-step explanation:
Answer:
because the graphs of the two equations overlap each other
Step-by-step explanation:
when two graphs have the same line, the line overlaps so it looks like only one line. therefore, the answer is
C) because the graphs of the two equations overlap each other.
Answer:
7 groups, 3 boys and 8 girls
Step-by-step explanation:
Let total number of groups be 
and total hikers in one group be 
if number of girls and boys in every group is same, then
....(1)
from (1) will either be 11 or 7
for 
the values won't be real.
For 
so there will be 7 groups with 11 hikers in each groups and every group will have 
boys and 
girls
