Answer:
3 < x < 17
Step-by-step explanation:
Given 2 sides then the possible range of the third side x is
difference of 2 sides < x < sum of 2 sides , that is
10 - 7 < x < 10 + 7
3 < x < 17
Hey I’m sure it’s 4! Sorry if I’m wrong that’s quite confusing
Answer:
-7,-5.8,-4.6,-3.4,-2.2
Step-by-step explanation:
A geometric sequence must have a common ratio.
-3 / 1 = -3
9 / -3 = -3
-27 / 9 = -3
81 / -27 = -3
The first sequence is a geometric sequence.
-5.8 / -7 = 0.829...
-4.6 / -5.8 = 0.793...
The second sequence is not a geometric sequence (it is an arithmetic sequence with a common difference of 1.2).
Answer:
1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the engineers are selected is not important, so the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
10 engineers selected from a set of 20.
5 best, from a set of 5.
Other 5, from a set of 20-5 = 15.
Totao outcomes:
10 engineers selected from a set of 20.
Probability:
1.63% probability that the 10 selected include include all the best 5 engineers in the group of 20
