Let a, b, c represent the numbers of subscribers who watched 1, 2, and 3 videos, respectively.
.. a +b +c = 312 . . . . . . . there are 312 subscribers, total
.. a +2b +3c = 740 . . . . there were 740 total views
Subtract double the first equation from the second.
.. (a +2b +3c) -2(a +b +c) = (740) -2(312)
.. c -a = 740 -624 = 116
116 more people watched all three videos than watched one video.
Answer:
1 / 8568
Step-by-step explanation:
The number of combinations is:
₁₈C₅ = (18! / (5! (18−5)!)
₁₈C₅ = 8568
There are 8568 possible groups of 5 that can be selected from 18. Only 1 of those groups contains the five youngest students. So the probability is:
P = 1 / 8568 ≈ 0.0117%
Answer:
14 ft
Step-by-step explanation:
Let x represent the number of segments of the divided wood beam
Let y represent the total length of the wood beam.
Given that each segment measures 3.5, the equation to express this scenario is given as
y = 3.5x
Thus, to find the length of the wood beam, substitute x = 4 into the equation.
We would have:
y = 3.5(4)
y = 14
Length of the wood beam = 14 ft
it isn't lined up to x straight while it's crooked
Answer:
The measure of angle x is 115 degrees
Step-by-step explanation:
Supplementary angles are angles which, when added together, equal 180 degrees. So, subtracting 65 from 180 would get you the answer(115).
