You can use the formula for conditional probability as Puzzling did. However in this problem it is easier just to restrict yourself and enumerate the cases that are left. 

<span>There are 4 jacks. One of them is a heart. So the probability is 1/4. </span>

<span>If you want to look at what the formula for conditional probability does, it adjusts your probability by restricting the "universe". </span>

<span>P(heart and jack)/P(jack) </span>
<span>= (1/52)/(4/52) = 1/4</span>

19) Solve the inequality. 7x − 9 &gt; 2x + 6 A) x &gt; 3 B) x &gt; 3 5 C) x &gt; −3 D) x &gt; − 3 5
Marianna [84]

Answer:

B

Step-by-step explanation:

Given

7x - 9 > 2x + 6 ( subtract 2x from both sides )

5x - 9 > 6 ( add 9 to both sides )

5x > 15 ( divide both sides by 3 )

x > 3 → B

In the table below, y is a linear function of x.
motikmotik

Answer:

y= -7

Step-by-step explanation:

y=ax+b

Find a where a=y2-y1 /x2-x1

y2=13,y1=5 x2=5,x1=3

substituting the values

a=13-5/5-2

a=8/2

a=4

substituting a into the formular

y=4x+b

taking x and y values let say 3 and 5 for x and y

the equation becomes

5=4(3)+b

5=12+b

5-12=b

-7=b

substituting the values of a and b into the equation

y=4x-7

when x=0

y=4(0)-7

y=0-7

y=-7

so when x=0,y=-7
