Answer:
Graph #1 - y=-20x+40
Graph #2 - y=5x+10
Step-by-step explanation: The first thing that you do is pull two points from each of the graphs and find the slope. To find the slope you use
<h2>
M = y2-y1/x2-x1</h2>
<u>FROM GRAPH #1:</u>
<h3>(3,40) (2,80)</h3>
(x1,y1) (x2,y2)
80-40/2-3
20/-1
M = -20
<u>FROM GRAPH #2:</u>
<h3>
(1,10) (3,20)</h3>
(x1,y1) (x2,y2)
20-10/3-1
10/2
M = 5
2. Now once you find the slope you will use the equation of a line formula to form an equation.
<h2>
y=mx+b</h2>
The (mx) is your slope, the (b) is the y-intercept. (any value on the y-axis)
3. Since we now know the equation of a line and the slope we will substitute the variables.
<u>Graph #1:</u>
y=mx+b
y=-20x+40
<u>Graph #2:</u>
y=mx+b
y=5x+10

Answer: y = -1.5+3x
Step-by-step explanation:
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
Hence option B is correct.

Answer:
17.0
Step-by-step explanation:
If you take the sin(39) or cos(51), it is equal to BC/27. Multiply by 27 on both sides to get 27cos(51) or 27sin(39)= x. Plug into the calculator, and voila.
