PLEASE HELP!! The AHS Football team did a weigh in at the start of training camp. The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg. Which of the following curves represents the data? A,B, Or C??
Answers
Answer: Choice C
=========================================================
Explanation:
The mean is 98, so that's the center of the distribution. This is where the highest point occurs because the most people are clustered around here. This rules out choice A and the answer is between B or C.
One standard deviation above the mean is 98+6 = 104. All we do is add on the standard deviation (6) to the mean (98) to get 104.
One standard deviation below the mean is 98-6 = 92
The graph that has tickmarks at 92 and 104 indicate we are exactly 1 standard deviation from the mean (98)
Similarly, 2 standard deviations above the mean is at 98+2*6 = 98+12 = 110. Or you could say 104+6 = 110.
2 standard deviations below the mean would get us to 98-2*6 = 98-12 = 86
The same idea applies to 3 standard deviations as well.
All of this matches with graph C. We can eliminate graph B by noticing that something like 95 is not a result of 98-6.

Step-by-step explanation:
Y=e×6x×(6x+1) × 5
y'= d/dx (e×6x ×(6x+1)×5)
y'=d/dx(30ex ×(6x+1))
y'=d/dx(180ex^2 + 30ex)
y'=d/dx(180ex^2) + d/dx (30ex)
Calculate the derivative

Write the equation of the line in slope intercept form that passes through the point (-6, 1) and has a slope of 1/6.
Answers
Answer:
y = 1/6x + 2
Step-by-step explanation:
point: (-6, 1)
slope 1/6
Our standard equation can be in the slope-intercept form: y = mx + b
m is the slope, which we know if 1/6. Plug this into our equation.
y = 1/6x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the point (-6, 1). Plug in the x and y values into the x and y of the standard equation.
1 = 1/6(-6) + b
To find b, multiply the slope and the input of x(-6)
1 = -1 + b
Now, add 1 from both sides to isolate b.
2 = b
Plug this into your standard equation.
y = 1/6x + 2
This is your equation.

Step-by-step explanation:
perimeter is total length of all side
height =2(x+2) (×2 bcause has 2 side)
length =2(3x-1) (×2 bcause has 2 side)
2x+4+6x-2=52
8x-2=52
8x=50 (8x is 8 times x, so move to the other side become divide)
x=50/8
