The slope of this line is 1 and the y-intercept is -2.
In order to find this, you need to put it in slope intercept form. This is done below for you.
3x - 3y = 6 -----> Subtract 3x from both sides
-3y = -3x + 6 -----> Divide by -3
y = x - 2
Now that you have this, you can find the slope by looking for the coefficient of x. In this case it is 1. You can find the intercept as the constant at the end, which is -2.
Answer:$51.2
Step-by-step explanation:
We have been given that at the restaurant, the cost of the meal before tax was $40. The tax is 8.5%.
The cost after tax would be .
Sheri wants to leave at least an 18% tip. The cost of meal after tip would be .
Therefore, the total cost of the dinner would be $51.2.
Answer:
f(x)=6x^2-6x
Step-by-step explanation:
25.8%
First, determine how many standard deviations from the norm that 3 tons are. So:
(3 - 2.43) / 0.88 = 0.57/0.88 = 0.647727273
So 3 tons would be 0.647727273 deviations from the norm. Now using a standard normal table, lookup the value 0.65 (the table I'm using has z-values to only 2 decimal places, so I rounded the z-value I got from 0.647727273 to 0.65). The value I got is 0.24215. Now this value is the probability of getting a value between the mean and the z-score. What I want is the probability of getting that z-score and anything higher. So subtract the value from 0.5, so 0.5 - 0.24215 = 0.25785 = 25.785%
So the probability that more than 3 tons will be dumped in a week is 25.8%
