here's your answer____⤵

You're essentially dealing a three-card hand from a deck of 50 (missing the spade and heart kings), wanting to know the probability of getting the remaining two kings among those three. The number of ways of dealing three cards is 50C3=1960050C3=19600; the number of hands with two kings is 4848 (one for each of the remaining cards in the hand); so the probability is 48/19600=3/122548/19600=3/1225.

Which of the following is most likely the next step in the series

Phantasy [73]

Answer:

A.

Step-by-step explanation:

In this series we see that an extra two dots (one on the top, one on the bottom of the same column) are being added on the left side.

-> It starts out at 3

-> Next it becomes 5, with the extra two on the left side

-> Now it is 7, with the last set of extra two also on the left side

Using this logic, we can infer that the most likely answer will be A.

Have a nice day!

Which of the following are incorrect expressions for slope?

vfiekz [6]

Answer:

Option B and C are correct.

$\frac{x_2-x_1}{y_2-y_1}$

$\frac{run}{rise}$ are the expression incorrect for slope

Step-by-step explanation:

Slope is defined as the change in the dependent variable relative to the change in the dependent variable

or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.

The vertical changes between any two points is rise

The horizontal changes between any two points is run.

Formula for slope is given by:

For any two points $(x_1, y_1)$ and $(x_2, y_2)$

then slope is:

$\text{Slope} =\frac{rise}{run}= \frac{y_2-y_1}{x_2-x_1}$

or we can write this as:

Δy = $y_2-y_1$

Δx = $x_2-x_1$

⇒ $\text{Slope} = \frac{\triangle y}{\triangle x}$

Therefore, the expression which are incorrect for slope are;

$\frac{x_2-x_1}{y_2-y_1}$

$\frac{run}{rise}$
