Answer:

b. not similar

Step-by-step explanation:

We see 3 different angle measures and the triangles have only one congruent angle. There is no evidence of side measures.

We don't have sufficient information to state the triangles are similar.

Explain why an archaeological matrix is important in archeology

Sphinxa [80]

Mr. Litterski creates a ball from rubber bands.

kupik [55]

Answer:

The surface area of the ball is of 29 square inches.

The volume of the ball is of 15 cubic inches.

Step-by-step explanation:

The ball has an spherical format:

Circumference of a sphere:

The circumference of a sphere is 6.2832 times the radius.

Surface area

$A = 4\pi r$

In which r is the radius.

Volume:

$V = \frac{4\pi r^3}{3}$

The circumference of the ball is 9.4 inches.

So the radius is:

$6.2832r = 9.4$

$r = \frac{9.4}{6.2832} = 1.53$

Surface area

$A = 4\pi(1.53)^2 = 29.3$

Rounding to the nearest unit, the surface area of the ball is of 29 square inches.

Volume:

$V = \frac{4\pi (1.53)^3}{3} = 14.9$

Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.

What are two ways to determine the probability that two independent events, A and B, will occur together.

stira [4]

Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring.

Some other examples of independent events are:

Landing on heads after tossing a coin AND rolling a 5 on a single 6-sided die.
Choosing a marble from a jar AND landing on heads after tossing a coin.

The events A and B are independent if any one of the following three equivalent conditions hold:

P(A ∩ B) = P(A)P(B)

P(A|B) = P(A) B has no effect on A

P(B|A) = P(B) A has no effect on B

Intuitively, two events are independent if the occurrence of one has no effect at all on the probability of the other.

To find the probability of two independent events that occur in sequence, find the probability of each event occurring separately, and then multiply the probabilities.

Multiplication Rule: When two events, A and B, are independent, the probability of both occurring is:

P(A and B) = P(A) · P(B)

To test whether two events A and B are independent, calculate P(A), P(B), and P(A ∩ B), and then check whether P(A ∩ B) equals P(A)P(B). If they are equal, A and B are independent; if not, they are dependent.

Prove the quotient of any two rational numbers is a rational number

Brut [27]

That is not possible, a quotient or any equation for that fact can only be rational when it lacks repeating {x} values. Take for instance this 2x11x2^2+(1+10)=

In the equation the {x} values would be most likely described as {2}. Since 2 was the quotient that was being repeating hence that equation not being rational. Hope this helps!
