The dependent variable will also increase hope this helps
Answer:
1. 14
2. 2.75
3. 7.25
4. 6.5
Step-by-step explanation:
1. You just make a dot plot and count the amount of dots there are.
2. You go to your dot plot and see the smallest amount and you get your answer.
3. Same thing as the smallest amount, except you just have to find the greatest amount.
4. You just find which number appears the most on the dot plot, and bam you got your answer.
If we let Q be the number of quarters and N be number of nickels, this is the formula we would use:
[1] 25Q + 5N = 635 (using cents instead of dollars)
We also know something about Q and N.
[2] Q + N = 51
So multiply both sides of the second equation by 5. The reason we do this is because we're going to need to cancel out one of the variables (either Q or N) to solve for the other one. If we multiply times 5, we'll have 5N in both equations.
5Q + 5N = 255
Now we have two equations, and the second one can be subtracted from the first.
25Q + 5N = 635
-(5Q + 5N) = -255
---------------------
20Q = 380
so
Q = 19
There are 19 quarters.
And since there are 51 coins in all, 51-19 = 32 nickels.
Answer & Step-by-step explanation:
We will only get a tornado if there is already a thunderstorm materializing
0.80 * 0.14 = 0.112
Probability of a tornado = 11.2%
There is a 100 - 14 = 86% chance of a tornado not being produced.
0.80 * 0.86 = 0.688
Probability of a storm and no tornado = 68.8%
Y= -2, -1, 0, 1 ,2
The function is linear
