Answer:
Step-by-step explanation:
so his class lasts 2 5/6 hrs...and he has already been in there for 1 2/5 hr
so the time he has left can be found by subtracting the time he has been there from the total time of the class
2 5/6 - 1 2/5....
(2 - 1) = 1 : (5/6 - 2/5 = 25/30 - 12/30 = 13/30)
so he has 1 13/30 hrs left <====
Answer:
y = 2x + 14
Step-by-step explanation:
First, you have to find the slope by using
y2-y1
x2-x1
In other words,
-2-6
-8+4
The slope is 2.
Then you plug the rest into point-slope form (you can use either of the points, I used the first one)
y-y1=m(x-x1)
Remember that m is the slope.
y+2=2(x+8)
Distribute the slope to the parenthesis
y+2=2x+16
Isolate the y variable
y=2x2x+14

Answer: C) There is a probability that the outcome is within 1 standard deviation of the mean.
Step-by-step explanation:
The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. According to the rule,
68% of data falls within the first standard deviation from the mean.
95% fall within two standard deviations.
99.7% fall within three standard deviations
Therefore, the correct answer is
C) There is a probability that the outcome is within 1 standard deviation of the mean.
