Answer:

A standard deck of cards has 52 cards.

probability of king is 4/52 and probability of a queen is 4/52

so if you do 4/52 + 4/52 = 8/52

8/52 in simplest form is 2/13

Step-by-step explanation:

Hope this helps Have a nice day

Passes through (-3, 1) and perpendicular to x=0
igomit [66]

Answer:

Find the equation of the line perpendicular to x = 0 that passes through (-3,1)

Step-by-step explanation:

Using the equation, y - y1 = m(x - x1)

Since x = 0, the gradient, m = 0

Hence, y - 1 = 0

∴ y = 1

Could someone explain why (-4)² is equal to 16 but -4² is equal to -16​
erica [24]

Answer:

It's all about the brackets.

Step-by-step explanation:

If we do (-4)^2, the brackets make it -4 x -4 and the two negatives make a positive of 16.

If we do -4^2, that means that the 4 is squared before putting the minus sign there so you have 4x4 = 16 then put the minus to get -16.

Hope this helps!

(-2, 11) &amp; (5,6)<br> What is the slope of the equation between these two points?
ololo11 [35]

Answer:

m =\dfrac{-5}{7}

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • Two points (-2,11) and (5,6) .

And we need to find out the slope of the equation between the two points. The slope of the line passing through two points , is given by ,

\implies Slope (m) =\dfrac{ y_2-y_1}{x_2-x_1}

  • Here the two points are (-2,11) and (5,6) .So put on the respective values ,

\implies Slope (m) =\dfrac{ 11 - 6}{-2-5}\\\\\implies Slope = \dfrac{5}{-7} \\\\\implies Slope = \dfrac{-5}{7}

<u>Hence</u><u> the</u><u> </u><u>slope</u><u> of</u><u> the</u><u> line</u><u> is</u><u> </u><u>-</u><u>5</u><u>/</u><u>7</u><u> </u><u>.</u>
