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%
Do 62 minus 3x-1. Whatever you get for that is the answer
Answer:
The solution in point form is (9,7) and the equation would be x+9, y=7
Step-by-step explanation:
By using moving the -4y to the right side and by flipping the signs you can turn the equation -x-4y=-37 into x=37-4y.
With this new equation you can use the substitution method and replace the x in -2x-5y=-53 with 37-4y, making it look like this: -2(37-4y)-5y=-53.
Then you solve for y getting y=7.
With the value of y, you can plug that into the equation x=37-4y so it will look like x=37-4(7)
Then you solve for x getting x=9
And with that you get the point (9,7)
Answer:
x=e^2/5
Step-by-step explanation:
log(20 x) - log(4) = 2
Add log(4) to both sides:
log(20 x) = 2 + log(4)
Cancel logarithms by taking exp of both sides:
20 x = 4 e^2
Divide both sides by 20:
And we get Answer:
x = e^2/5
