Answer:
(0,-2)
Step-by-step explanation:
you can multiply the first equation by 6 and add it to the other equation to eliminate the x then you get -29y=58 then you divide both sides of the equation by -29 to get y=-2 so now you know x=0 and y =-2
Answer: The experimental probability is 70 %
Step-by-step explanation:
According to the given question have to find that the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings
As we know that,
![Probability = \frac{number of favourable outcomes}{total possible outcomes}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7Bnumber%20of%20favourable%20outcomes%7D%7Btotal%20possible%20outcomes%7D)
If 10th-grade student chosen at random has at least one, but no more than two, siblings
Therefore, there can be one or two siblings
Such that, the total number of such students ![=18+10=28](https://tex.z-dn.net/?f=%3D18%2B10%3D28)
Now, number of favorable outcomes =28 and total number of students
![=4+18+10+8=40](https://tex.z-dn.net/?f=%3D4%2B18%2B10%2B8%3D40)
Now,
![Probability = \frac{number of favourable outcomes}{total possible outcomes}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7Bnumber%20of%20favourable%20outcomes%7D%7Btotal%20possible%20outcomes%7D)

24 pounds
In the first two weeks she only lost 2 pounds. In the remaining 11 weeks of her diet she lost 2 pounds a week so 11 x 2 = 22 then add on the 2 pounds lost from the first two weeks 22+2=24.
