I think it is B and C sorry if it’s not right but that’s what I think it is
Answer:
4/15
Step-by-step explanation:
There are red, green and blue marbles in the bag. The total of all the probabilities of selecting red, green and blue marbles is 1.00, or just 1.
So, to find the probability of selecting a blue marble, we add together 1/3 and 2/5 and subtract the total from 1:
1 - (1/3 + 2/5)
or:
1 - (5/15 + 6/15)
or:
1 - 11/15, or 4/15 (answer)
Answer:
y=3x+4
Step-by-step explanation:
first you find the slope by doing change in y over change in x. The change in y is 9 because 7-(-2)=9. The change in x is 3 because 1-(-2)=3. Then you do 9/3 which is 3, which is your slope, or m.
So now you know y=3x+b, then you substitute one of the points in for x and y, and you get 7=3(1)+b, where b is your y-intercept. then you solve, and find that b=4.
Now you put it into slope intercept form, which is y=mx+b, where m=3 and b=4, so you are left with y=3x+4.
Leave a thanks if I am correct please.
The lines are parallel (meaning they have the same slope) so there is no solution. If the lines overlap then there is infinite solutions. If the lines cross there is one solution.
The only way to have more than one solution but not infinite is if the graphs are something other than lines.
Yes it is not because 40 thousand + 5 thousand = 90,000 which is close to her goal
