Answer:
(
y
−
6
)
=
0
(
x
+
7
)
Explanation:
The point-slope formula states:
(
y
−
y
1
)
=
m
(
x
−
x
1
)
Where
m
is the slope and
(
x
1
y
1
)
is a point the line passes through.
Substituting the values from the equation gives:
(
y
−
6
)
=
0
(
x
−
−
7
)
(
y
−
6
)
=
0
(
x
+
7
)
Formulas tab > in the Function Library group, click Lookup & Reference button, select VLOOKUP. Type A3 in the Lookup_value argument box. Type Abbreviation in the Table_array argument box. Type 2 in the Col_num argument box. Type False in the Rang_lookup box. Click OK, is this what you were looking for?
total number of cards: 12 + 27 + 91 = 130
total number of cards with a circle: 91
so you have a 91/130 probability which reduces to 7/10 probability
4x+2(3-2x)=10, 4x+6-4x=10, x+6=10, x=4
