There are a total of 68 cars in the parking lot (sum of all values on the table).
Selecting blue OR a chevy, means all blue and all chevies are valid choices...there are 7+9+8+7+5 (blue cars and chevy cars) = 36:
36/68 = 9/17
Selecting blue AND a chevy - There are 8 blue chevies:
<span>8/68= </span>2/17
GIVEN that the car is blue means we're <em>only selecting from </em>the 7+9+8 = 24 blue cars on the lot which are chevies...and there are 8 blue chevies:
8/24 = 1/3
√4=2, and √45=√(9*5)=√9 *√5=3√5
so you have 2/(3√5)
Multiply both top and bottom by √5 to eliminate the √ in the denominator:
(2√5)/15 is the final answer.
Answer:
Hours.
Step-by-step explanation:
Snacks is dependent because the number of snacks depends on the hours gone.
Step 1: 1
(((x3) - (2•5x2)) + 29x) - 30 = 0
Step 2 2.1 x3-10x2+29x-30 is not a perfect cube
Step 3 Factoring: x3-10x2+29x-30
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 29x-30
Group 2: -10x2+x3
Pull out from each group separately :
Group 1: (29x-30) • (1)
Group 2: (x-10) • (x2)
(-3, 1)
4x-9y=-21
+-4x-3y=9
-12y= -12
y=1
4x- 9(1)= -21
4x-9=-21
+9 +9
4x= -12
x=-3
