The answer to the question is use photomath
Hello :
given equation : y = ax +b the slope is : a
Answer:
The answer is 560
Step-by-step explanation:
I just had this on a exam and answered 560 and it was correct.
Answer:
7
Step-by-step explanation:
Since the goal is to draw three marbles of the same colour, regardless of which colour that is, the worst possible scenario would be drawing two marbles of each color in the first six picks (2 red, 2 white and 2 blue). At this point, with the 7th pick, no matter what colour marble the student picks will form three of the same kind.
Therefore, the minimum number of marbles which students should take from the box to ensure that at least three of them are of the same colour is 7.
Ok let's start with question 1.
1. The equation is given. If she advices 360 people each week for 4 week she earns...
4(80+360(15)/100) = $536
2. In this problem instead of evaluating M we solve for n with M given.
140=80+15n/100
n=400 people
3. The new equation will still follow the same format.
M=65+21n/100
4. This will be the intersection point of the two lines. So when does...
80+15n/10=65+21n/100
We just have to solve for n.
-0.06n=-15
n=250 people
