Answer: first option
Step-by-step explanation:
The volume of a regular pyramid can be calculated with the following fromula:
Where B is the area of the base of the pyramid and h iis the height of the pyramid.
The base is a square, therefore, its area B is:
You know that the height is 3, therefore, you can substitute these values into the formula.
THerefore, the volume of the pyramid is:
The answer is A.
The way you know this is by graphing the first function.
The second function is in a different format, so you just have to isolate Y.
-1/3x + y = -1
y= 1/3x -1 OR y= -1 + 1/3x
both of the functions have the same slope, but different y-intercepts. therefore, they'll never touch. making them infinite solutions.
it's also A because both of the slopes are positive, the slopes in graph D are negative.
So, the answer is A.

x = number of hours
want to find probability (P) x >= 13
x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.
P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413
To convert that to percentage, multiply 100, to get 84.13%
Answer:
84
Step-by-step explanation:
2 even numbers and its sum is 12: 4, 8 and 6, 6
tenth place > ones place 84
