15·0.8 + x = 30·0.9 --> x = 15
C. is the correct answer
Answer:7
Step-by-step explanation:distance between E and M forms a diagonal. Thus from the y axis we get a triangle. So using pythagoras theorem we have. EM^2= 5^2 +2^2. EM=\/(5+2)^2. EM=7
20% of 106
= 0.20 * 106
= 21.2
21.2 = 10.6% of 21.2 / 0.106
= 200 answer
2. 56 * 0.055 / 0.35
= 8.8
3. 6.4 / 0.8 = 8
Answer:
4.2 team members per day
Step-by-step explanation:
5 + 4 + 2 + 7 + 3 = 21
21/5 = 4.2
Answer: Probability P = 1/1716
Step-by-step explanation:
Definition
For permutation ( order is important)
nPr = n!/(n-r)!
Given;
Total number of members in the committee = 13
Total number of members to be selected = 3
Since order is important in this case.
The total number (Tt) of possible ways of selecting three executives from the committee members is given as
Tt = 13P3 (since order is important)
Tt = 13!/(13-3)!
Tt = 13!/10!
Tt = 1716
The probability P of randomly selecting the three members who currently hold the positions of chairman, ranking member, and treasurer and reassigning them to their current positions is equal to
P = number of favourable outcomes/ number of possible outcomes
Number of favourable outcomes = 1 (i.e 1×1×1 = 1) one option for each post.
Number of possible outcomes = Tt = 1716
P = 1/1716
