The equation:
models the amount of money in your wallet. Where:
x: Represents the number of weeks from today
y: Represents the total in dollars
This graph is indicated in the figure bellow. The slope of this graph is 10, that is, the term accompanying the variable x. The slope of a line is the number of units the line rises (or falls) vertically for each unit of horizontal change from left to right. So, in this problem, this represents how much your adding to your wallet each week. You are adding $10 dollars for x weeks.
Answer:
Where x represent the successes and n the total of marbles and replacing we got:
Step-by-step explanation:
For this case we have the following types of marbles
3 white, 3 yellow, 2 black
The total of marble for this case are:
And we have a total of 3 yelow marbles. We can apply the definition of probability given by:
Where x represent the successes and n the total of marbles and replacing we got:
Yes, you can do it using substitution. However, elimination would be better because you could just add the two equations and have y cancelled out immediately.
Answer:50 degress 2/2
Step-by-step explanation:
2/2
Answer:
- {-3.2, -1.4, 0.4 2.2, 4.0, 5.8}
- common difference: 1.8
Step-by-step explanation:
The difference between the two numbers is ...
5.8 -(-3.2) = 9
The four "means" divide this interval into 5 parts, so each part has a length of ...
9/5 = 1.8 . . . . the common difference
The values of the "means" can be found by adding 1.8 successively:
-3.2 +1.8 = -1.4
-1.4 +1.8 = 0.4
0.4 +1.8 = 2.2
2.2 +1.8 = 4.0
Including the given numbers, the arithmetic sequence is ...
-3.2, -1.4, 0.4, 2.2, 4.0, 5.8 . . . . . common difference of 1.8
