Answer:
C.
Step-by-step explanation:
Base area = 9 × 13
= 117 square feet
Now
Volume of pyramid = (1/3)(A)(H)
= (1/3)(117)(30)
= 117 × 10
= 1170 cubic feet
Answer:
12
Step-by-step explanation:
To find the mean of a set of numbers, add all the numbers together. Then, divide the sum by how many numbers you had to begin with.
Add the numbers together:
10 + 12 + 15 + 11
= 48 This is the sum of the data
Count how many numbers you had:
10, 12, 15 and 11 are FOUR numbers (amount of data).
Divide the sum of the data by the amount of data.
48 ÷ 4 = 12 This is the mean
The mean of 10, 12, 15, 11 is 12.
Answer:

Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Slope: 
Point: (3, 2) = (x1, y1)
To write the equation in point-slope form, we need to know the values of the slope and one point. Since we've already been given those values, all we have to do is input them into the equation:
y - y1 = m(x - x1)

The equation in point-slope form is:
