The correct answer is choice B. It takes 3 congruent pyramids to create a cube. This is why the formula for volume of a pyramid is 1/3Bh.

In a cube the area of the base (length and width) and height are all the same, so b cubed.

Pie

Answer:

D. 48

Step-by-step explanation:

Let's first find the probability that in the first 40 trials, exactly two of the coins are heads.

We know that there were 16 such outcomes of 2 heads and 1 tail, and there was a total of 40 possible outcomes. So our probability is:

16 / 40 = 4 / 10 = 2/5

We can assume that the probability that in the next 120 trials, about 2/5 of the outcomes will also be 2 heads and 1 tail. So, we multiply 2/5 by 120 to figure out that exact number:

(2/5) * 120 = 240/5 = 48

The answer is thus D.

Find three consecutive positive integers such that the sum of their squares is 2354. What is the largest integer?
Ilya [14]

Answer:

The largest integer is 29.

Step-by-step explanation:

Let the consecutive positive integers are x, x+1 and x+2.

The square of sum of squares of three consecutive positive integers is 2354 such that,

x^2+(x+1)^2+(x+2)^2=2354\\\\x^2+x^2+2x+1+x^2+4+4x=2354\\\\3x^2+6x+5=2354\\\\3x^2+6x- 2349=0

It is a quadratic equation whose solution is given by :

x = 27 and x = -29

First positive integer = 27

Second positive integer = 27+1 = 28

Third positive integer = 27+2 = 29

Hence, the largest integer is 29.
