The delivery driver has to make deliveries at 5 locations <span>among the 6 locations. </span>This means the order of the probability is important because the route he will take from A to B is different with A to C.
So, you need to use permutation for this problem. The calculation would be:
6P5= 6!/ (6-5)!= 720 different routes
54/35 is the answer to this question
Answer:
X = -(146/123) , Y = 21/41
Step-by-step explanation:
2-12x-4y = 32-8y-39x
39x-12x+8y-4y = 32-2
27x+4y = 30
27x+4y-30 = 0
32-8y-39x = 6y-6x
32-8y-6y-39x+6x = 0
-33x-14y+32 = 0
Answer:
x=-2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x+3)(2)−4=0
4x+12+−4=0(Distribute)
(4x)+(12+−4)=0(Combine Like Terms)
4x+8=0
4x+8=0
Step 2: Subtract 8 from both sides.
4x+8−8=0−8
4x=−8
Step 3: Divide both sides by 4.
4x/4 =-8/4
x=−2
Answer:
27
Step-by-step explanation:
Given :
Total number of people : 36
Ratio of people who prefer red to blue
Red : Blue = 3 : 9 = 1 : 3
according to the ratio, for every 4 people, 1 prefers red and 3 prefers blue.
Expressed mathematically:
People who prefer blue = 3/4 of the total number of people
In our case, total number is 36 hence,
People who prefer blue (and hence the number of blue pens he should order),
= 3/4 x 36 = 27
