Given:
Two cards are selected from a standard deck of 52 playing cards.
The first card is not replaced before the second card is selected.
To find:
The probability of selecting a four and then selecting a two.
Solution:
We know that,
Total number of cards = 52
Number of four cards = 4
Number of two cards = 4
Now,
[tex]\text{Probability}=\dfrac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}[/tex]
Probability of selecting a four = [tex]\dfrac{4}{52}[/tex]
After selecting a card, then number of remaining cards is 51.
Probability of selecting a two = [tex]\dfrac{4}{51}[/tex]
So, the probability of selecting a four and then selecting a two is
[tex]P=\dfrac{4}{52}\times \dfrac{4}{51}[/tex]
[tex]P=\dfrac{1}{13}\times \dfrac{4}{51}[/tex]
[tex]P=\dfrac{4}{663}[/tex]
Therefore, the required probability is [tex]\dfrac{4}{663}[/tex].

How can you find the value of x? in 3x= 2 1/4
Answer:Tap for more steps... By the Sum Rule, the derivative of x 4 + 3 x 2 x 4 + 3 x 2 with respect to x x is d d x [ x 4] + d d x [ 3 x 2] d d x [ x 4] + d d x [ 3 x 2]. Differentiate using the Power Rule which states that d d x [ x n] d d x [ x n] is n x n − 1 n x n - 1 where n = 4 n = 4.

Answer:
B'(6, 6) ; C'(12, 6)
Step-by-step explanation:
The points are not labeled so I'm going to assume the points are as follows:
A(3, 9)
B(3, 3)
C(6, 3)
In order to dilate with a scale factor of 2, simply multiply the x and y coordinates by 2.
B(3, 3) ⇒ B'(6, 6)
C(6, 3) ⇒ C'(12, 6)

The cost of 10 balls is 280. Find the cost of 19 balls.
Answer:
$532
Step-by-step explanation:
Hey There!
So to solve this problem the first thing that we want to do is find the cost of 1 ball
To do so we divide the total cost of 10 balls by 10
280/10=28 so each ball cost 28
now to find the cost of 19 balls we multiply the cost of 1 ball by 19
18x28=532
thus meaning 19 balls cost $532
Answer:
$532
Step-by-step explanation:
We need to find the cost of 1 ball and then multiply it by 19, here is the math:
280/10=28
Now we know that 28 is the cost of 1 ball.
28 x 19=532
The cost of 19 balls is $532

Step-by-step explanation:
I would look at this triangle and notice that x can be solved by setting up a ratio.
I generally put the short side of the triangle on the top and the long side on the bottom
4/x = x/9
You then cross multiply to get 36=x^2, or +-6=x
A length of a triangle cannot be negative, so we are left with the answer x=6

P(x) 0.08 0.23 0.44 0.12 0.24
A) The values of x are negative
B) The probability values are not increasing
C The probability values do not add to 1
D) The probability values are not discrete
Answer:
C The probability values do not add to 1
Step-by-step explanation:
Given
The above table
Required
Why is it not a probability distribution
In probability, the sum of all probabilities must equal 0.
But in this case:
[tex]\sum P(x) \ne 0[/tex]
Because:
[tex]0.08 + 0.23 + 0.44 + 0.12 + 0.24 \ne 0[/tex]
[tex]1.11 \ne 0[/tex]

Part 1:
65 - 65 * (20/100)
= 65 - 13
= 52
Part 2:
52 + 52 * (5/100)
= 52 + 2.6

Given the graphs of f(x) = -x + 2 and g(x) = 5x – 4, what is the solution to the equation f(x) = g(x)?
A) -4
B) 0
C) 1
D) 2
Answer:
c) 1
Step-by-step explanation:
f(x) = g(x)
-x+2 = 5x-4
+x +x
2 = 6x -4
+4 +4
6 = 6x
(divide both sides by 6)
1 = x
