Answer:

I believe it would be a constant. If we are talking about the values on the x axis, a.k.a the horizontal line, it is at coordinates (2,-2) when the constant starts. Its the same y-axis throughout the rest of the graph. This means it is a constant.

A flush in the card game of poker occurs if a player gets five cards that are all the same suit (clubs, diamonds, hearts, or

Artyom0805 [142]

Answer:

The probability is 0.000495

Step-by-step explanation:

As per the question:

Total no. of cards in a deck = 52

No. of spades in a deck = 13

Now, we have to select 5 cards in a deck such that they belong to the same suit, i.e., spades.

The no. of ways of selecting 5 cards from a deck = $^{52}C_{5} = \frac{52!}{5!(52 - 5)!} = \frac{52!}{5!47!}$

The no. of ways of selecting 5 cards from 13 spade cards = $^{13}C_{5} = \frac{13!}{5!(13 - 5)!} = \frac{13!}{5!8!}$

Now,

Probability that the selected 5 cards are all spades, P(E) = $\frac{No.\ of\ ways\ of\ selecting\ 5\ cards\ from\ 13\ spade\ cards}{No.\ of\ ways\ of\ selecting\ 5\ cards\ from\ a\ deck}$

P(E) = $\frac{^{13}C_{5}}{^{52}C_{5}}$

P(E) = $\frac{\frac{13!}{5!8!}}{\frac{52!}{5!52!}}$

P(E) = $\frac{\frac{13\times 12\times 11\tiems 10\times 9}{5\times 4\times 3\times 2\times 1}}{\frac{52\times 51\times 50\times 49\times 48}{5\times 4\times 3\times 2\times 1}}$

P(E) = $\frac{13\times 12\times 11\tiems 10\times 9}{52\times 51\times 50\times 49\times 48} = 4.95\times 10^{- 4} = 0.000495$

What is the value of x to the nearest degree? 48 42 84 24

Cerrena [4.2K]

Answer:

The value of the angle x is 48°.

Step-by-step explanation:

Base of the triangle = 10

Height of the triangle = 11

$\tanx =\frac{Height}{Base}$

$\tanx =\frac{11}{10}=1.1$

$x =\tan^{-1}1.1=47.7263^o\approx 48^o$

The value of the angle x to the nearest degree is 48°.

Plz help if you can!!!!!!!!!!

Answer: The two triangles are similar because the angles are congruent.

Step-by-step explanation: If you add the given measures of the angles given, then subtract from 180, the remainder is equal to the measure of the angle given for the other triangle.

180 - (103 + 22) = 55

180 - (22 + 55) = 103

So both triangles have the same angle measurements.

What is the exact area of a circle with a diameter of 18 feet?

Kitty [74]

The formula for the area of a circle is

$\pi r^{2}$

We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.

$\pi 9^{2} =81 \pi$

So the answer is B, 81 pi square feet
