Alexandra [31]

Answer:

The angles in a triangle should always add up to 180 degrees.

The four angles made by a set of intersecting lines will always add up to 360 degrees and the ones across from eachother are always the same.

This means that the triangle's unmarked angle is 60 degrees.

2*24 = 48 and 3*24 = 72       48 + 72 + 60 = 180 degrees

24 will be your correct answer.

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible c
lutik1710 [3]

Answer:

Tamara should expect the sum of the two cubes to be equal to 5 20 times.

Step-by-step explanation:

The sample space of rolling a number cube are:

S = {1, 2, 3, 4, 5, 6}

If two such cubes are rolled together, then the sum of the two cubes will be 5 for the combinations below:

S₁ = {(1, 4), (2, 3), (3, 2) and (4, 1)}

The total number of outcomes will be, <em>N</em> = 36.

Compute the probability that the sum of rolling two numbered cubes as follows:

P(\text{Sum}=5)=\frac{4}{36}=\frac{1}{9}

Let <em>X</em> = number of time the sum of the two numbers on two cubes is 5.

Two numbered cubes are rolled <em>n</em> = 180 times.

The event of getting a sum of 5 in independent of the other results.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 180 and <em>p</em> = \frac{1}{9}.

The expected value of <em>X</em> is:

E(X)=np

Compute the expected number of times Tamara expects the sum of the two cubes to be equal to 5 as follow:

E(X)=np\\=180\times \frac{1}{9}\\=20

Thus, Tamara should expect the sum of the two cubes to be equal to 5 20 times.

Base area = 1 • 2/2 (b • h /2)

= 1

Height = 17

17 • 1 = 17 m^3
