Each cube in this solid figure is a unit cube.<br><br> What is the volume of this solid figure?
padilas [110]

Answer:

The volume of this given solid figure is 18 cubic units.

Step-by-step explanation:

Here, given the volume of 1 small cube = 1 cubic units

Now, counting the total cubes in the given solid figure, we get

Number of cubes in base row = 10

Number of cubes in middle row  = 6

Number of cubes in top most row = 2

So, the total number of cubes in the figure  = 10 + 6 + 2 = 18 cubes

So, the volume of 18 cubes  = 18 ( Volume of 1 small cube)

                                              =  18 x (1 cubic units)  = 18 cubic units

Hence, the volume of this given solid figure is 18 cubic units.

13) The side length of the following cube is 8 cm. what is the length of the diagonal through its center?​
Scorpion4ik [409]

Answer: \sqrt{3} x 8 = 13.8564064606

Step-by-step explanation: The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3 (\sqrt{3}). Therefore, square root 3 (\sqrt{3}) is multiplied by the length (8 in our case) of either 6 faces of the cube.

Hope it helped!

The probability that a new car battery functions for more than 10,000 miles is .8, the probability that it functions for more th
MAXImum [283]

Answer:

There is a 50% probability that its total life will exceed 20,000 miles.

Step-by-step explanation:

To solve this question, we use the following formula:

P(A|B) = \frac{P(A \cap B)}{P(B)}

In which P(A|B) is the probability of A happening, given that B has happened, P(A \cap B) is the probability of A and B happening, and P(B) is the probability of B happening.

In this problem, we want:

The probability of the total life of the car battery exceeding 20,000 miles, given that it exceeded 10,000 miles.

P(A \cap B) is the probability of exceeding 20,000 and 10,000 miles. It is the same as the probability of exceeding 20,000 miles(If it exceeded 20,000 miles, necessarily it will have exceeded 10,000 miles). So P(A \cap B) = 0.4

P(B) is the probability of exceeding 10,000 miles. So P(B) = 0.8)

So

P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{0.4}{0.8} = 0.5

There is a 50% probability that its total life will exceed 20,000 miles.
