Using probability concepts, it is found that P(S and D) = 0.1275.

-----------------------

A probability is the <u>number of desired outcomes divided by the number of desired outcomes</u>.
In a standard deck, there are 52 cards.
Of those, 13 are spades, and 13 are diamond.

The probability of selecting a spade with the first card is 13/52. Then, there is a 13/51 probability of selecting a diamond with the second. The same is valid for diamond then space, which means that the probability is multiplied by 2. Thus, the desired probability is:

$P(S \cap D) = 2 \times \frac{13}{52} \times \frac{13}{51} = \frac{2\times 13 \times 13}{52 \times 51} = 0.1275$

Thus, P(S and D) = 0.1275.

The sum of the measures of the angles is 180. The sum of the measures of the second and third angles is two times the measure of

grigory [225]

<h2>60,47,73</h2>

Step-by-step explanation:

Let the first angle be $a$ degrees

Let the second angle be $b$ degrees

Let the third angle be $c$ degrees

It is given that sum of angles is $180$ degrees.

so, $a+b+c=180$ ...(i)

It is given that sum of the measures of the second and third angles is two times the measure of the first angle.

$b+c=2\times a$ ...(ii)

It is given that the third angle is 26 more than the second.

$c=26+b$ ...(iii)

using (ii) and (iii),

$b+b+26=2a$

$b+13=a$

using (i),(ii) and (iii),

$a+b+c=a+a-13+26+b=a+a-13+26+a-13=3a$

$3a=180$

$a=60$

$b=a-13=60-13=47$

$c=26+b=26+47=73$

5Step-by-step explanation:

If you use the distance formula you can solve it pretty easily. The distance formula is:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2} \\$

The two points you want are A and D. A is (-1, -4) and D is (3, -1). Plug that into the formula...

d = $\sqrt{(3 - (-1))^2 + (-1 - (-4))^2}$

d = $\sqrt{4^2 + 3^2}$

d = $\sqrt{16 + 9}$

d = $\sqrt{25}$

I can solve it in a different way if you want me to.
