You are dealt two cards successively (without replacement) from a shuffled deck of 52 playing cards. Find the probability that t

icang [17]

Answer:

The probability that the first card is a Heart and the second card is a Spade is 0.064.

Step-by-step explanation:

A standard deck of 52 cards is shuffled and two cards are drawn without replacement.

The denominations of the cards are as follows:

Spades (S) = 13

Hearts (H) = 13

Diamonds (D) = 13

Clubs (C) = 13

Compute the probability of selecting a Heart first as follows:

$P(H)=\frac{13}{52}=0.25$

Compute the probability of selecting a Spade second as follows:

$P(S)=\frac{13}{51}=0.255$

Since the two cards are selected without replacement the second draw is independent of the other.

Then the probability that the first card is a Heart and the second card is a Spade is:

$P(1st\ H\cap 2nd\ S)=P(H)\times P(S)$

$=0.25\times 0.255\\=0.06375\\\approx 0.064$

Thus, the probability that the first card is a Heart and the second card is a Spade is 0.064.

Two paths in a park intersect so that one of the angles at the intersection is 75°.What are the three other angle measurements f

oksian1 [2.3K]

Answer:

105°, 75°, and 105°.

Step-by-step explanation:

If two straight paths intersect at a point , four angles will be formed.

These are pairs of vertical angles.

The adjacent angles add up to 180°

If one of the angles is 75°, the supplement will be

$180 - 75 = 105 \degree$

Therefore the three other angles will be , 105°, 75°, and 105°.

Can someone help me with this please!! I’ll give brainliest plus free points

Answer:

The answer to your question is: x₁ = 9 ; x₂ = -2, third option

Step-by-step explanation:

The excluded values are those that make the denominator equal to zero.

To find the excluded values, just factor the denominator and equal to zero to find the roots.

Process

x² - 7x - 18

- Find to numbers that added gives -7 and multiply -18.

- These numbers are -9 and + 2, because

-9 + 2 = -7

and -9 x 2 = -18

(x - 9) (x + 2) = 0

x₁ - 9 = 0 x₂ + 2 = 0

x₁ = 9 x₂ = -2

Test

(9)² - 7(9) - 18 (-2)² - 7(-2) - 18

81 - 63 - 18 4 + 14 - 18

81 - 81 18 - 18
