Point Slope Form looks like this:
First, we need to find the m value, or slope. We can do this by using this equation:
4 - 8 / 4 + 4 = -4/8 = -1/2
m = -1/2
Now, select one of the coordinate points, input those values and m, and solve for b.
4 = -1/2(4) + b
4 = -2 + b
Add 2 to both sides.
6 = b
y = -1/2x + 6
Now, input any number for x (I prefer 0, the y-intercept), and solve for y.
y = -1/2(0) + 6
y = 6
(0, 6)
After doing that, you can input that coordinate point into Point-Slope Form.
y - 6 = -1/2(x - 0)
Answer:
68.27%
Step-by-step explanation:
An empirical rule for a normal distribution states that 68.27% of data is within 1 standard deviation () of the mean (), 95.45% of the data is within 2 standard deviations of the mean, and 99.73% of the data is within 3 standard deviations of the mean.
The problem asks for the probability that a battery will last between 6.8 and 9.2 hours considering that =8 and =1.2.
So, if the distribution is normal, the 68.27% of data is within 1, that is between and , replacing the values we have
8-1.2=6.8 and 8+1.2=9.2
So, 68.27% of batteries will last between 6.8 and 9.2 hours
Answer:
The first box
Step-by-step explanation:
In a linear function you cannot have 2 of the same X numbers. Ex) You cannot have 2 -4's in the X row. In the Y, you may. But never the X.
