The axis of symmetry is x=2.
Answer:
x = 15
Step-by-step explanation:
<u>Step 1: Make an expression</u>
<em>4/6 = 10/x</em>
<em />
<u>Step 2: Cross multiply</u>
4/6 = 10/x
<em>4x = 60</em>
<em />
<u>Step 3: Divide both sides by 4</u>
4x / 4 = 60 / 4
<em>x = 15</em>
<em />
Answer: x = 15
Explanation:
The line through the data points has a negative slope, showing that y is <em>negatively correlated</em> with x. The "inversely proportional" relationship means the product of x and y is a constant. It produces a curved graph like the one attached.
Range is about subtracting the lowest number from the highest number!
The lowest number is 54.
The highest number is 65.
65 - 54 = 11
<h2>Answer: 11</h2>
Answer:6.986
Step-by-step explanation:
To find the standard deviation of a set of data I find it easiest to make a chart. First you must find the mean of your data. In this case it is 476.85. Then you must subtract the mean from each data point, and square each number. Now you take your new set of data that has been squared and find the mean of these numbers. This is 48.8006. Lastly, take the square root of this number. In this case your standard deviation is 6.986.
