When we are partitioning in division, we are dividing the number into its place values, and then applying the divisor to each of the values.
For example in the first problem, we have 642, which is also 600 + 40 + 2.
That means we'll have three division problems.
600 ÷ 2 = 300
40 ÷ 2 = 20
2 ÷ 2 = 1
Which means that 642 ÷ 2 = 300 + 20 + 1, or 321.
You can apply this format to the other two problems to find their answers.
If you do, you should get that 969 ÷ 3 = 323, and 844 ÷ 4 = 211.
Hope this helps!
Answer:
answer i d
Step-by-step explanation:
Answer:
59/1000
Step-by-step explanation:
Given in the question, the section will follow
<u> Event Number of employees Classification</u>
A 120 Supervisors
B 50 Maintenance
C 1460 Production
D 302 Management
E 68 Secretarial
<u>Total 2000 all employees</u>
Probability that a person selected is in maintenance
P(M)= 50/2000 =1/40
Probability that a person selected in in secretarial
P(S)=68/2000 = 17/500
The probability that the first person selected is either in maintenance or in secretarial you add the two
1/40 + 17/500 = 59/1000

Answer: 120 different ways</h3>
=======================================================
Explanation:
There are...
- 6 ways to select the first place winner
- 5 ways to pick the second place winner
- 4 ways to pick the third place winner
We start with 6, and count down by 1 each time we fill up a slot. We stop once the third slot is filled or accounted for. The countdown is to ensure that we don't pick the same person twice. From here, multiply those values: 6*5*4 = 30*4 = 120
Interestingly, this is equal to 5! = 5*4*3*2*1 = 120 because the 3*2 becomes 6 and that *1 at the end doesn't affect things. Though usually results of permutation problems don't always end up like this. The order matters because a result like ABC is different from BAC, where A,B,C,D,E,F are the six school organizations.
As a slightly longer way to do the problem, you can use the nPr formula which is
where n = 6 and r = 3 in this case. The exclamation marks indicate factorial. If you go this route, you should find that one of the steps will involve 6*5*4.
