Answer:
5/18, 13/18
Step-by-step explanation:
The basic probability of anything is Specific Outcome / Total Outcomes
The specific outcome here is pulling a purple marble. We see there are 5 purple marbles therefore there are 5 ways to get them. The total outcomes are the total number of marbles which is 18. Therefore, the answer is 5/18
The complement of a probability is 1 minus the original probability, so, it would be 1 - 5/18 here getting us 13/18 as the answer.
Answer:
The proof of Pythagorean Theorem in mathematics is very important. In a right angle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. States that in a right triangle that, the square of a (a²) plus the square of b (b²) is equal to the square of c (c²).
Answer:
missing 9400
Step-by-step explanation:
14300+16700+17900+18500=67400
67400<76800
76800-16700=9400

Answer:
Step-by-step explanation:
3x+4=−y
3x+4+y=−y+y(Add y to both sides)
3x+y+4=0
3x+y+4+−3x=0+−3x(Add -3x to both sides)
y+4=−3x
y+4+−4=−3x+−4(Add -4 to both sides)
y=−3x−4
Step: Substitute−3x−4foryin2x+y=0:
2x+y=0
2x+−3x−4=0
−x−4=0(Simplify both sides of the equation)
−x−4+4=0+4(Add 4 to both sides)
−x=4
−x
−1
=
4
−1
(Divide both sides by -1)
x=−4
Step: Substitute−4forxiny=−3x−4:
y=−3x−4
y=(−3)(−4)−4
y=8(Simplify both sides of the equation)
Answer:
x=−4 and y=8
