Answer:

\frac{1716}{132600}

Step-by-step explanation:

Assuming they removed the jokers there are 52 cards in a deck and 13 hearts

You can calculate the odds of something by multiplying the odds together, because you don't put back the card you drew you have to subtract 1 from both the numerator and denominator

(\frac{13}{52})(\frac{12}{51})(\frac{11}{50})=\frac{1716}{132600}

Therefore the probability of pulling 3 cards that are all hearts are \frac{1716}{132600}

There are 33 questions on Allison's
Brums [2.3K]

Answer:

x=15

y=18

Step-by-step explanation:

then x+y=33

and 2x+5y=120

then x=33–y

since 2x+5y=120

then 2(33–y)+5y=120

then 66–2y+5y=120

then 66+3y=120

then 3y=120–66

then 3y=54

then y=54/3

then y=18

then x=33–18=15

What is the parallel slope intercept form pls help?​
malfutka [58]
<h2>Answer:</h2>

If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.

-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b

Now that we have the y-intercept, we can create the equation.

y = 4x - 17

We can prove this by graphing both lines, like so.
