The graph is to the left of -3, so it's < or ≤.
The circle is filled in so -3 also satisfies the inequality, so it's ≤.
The answer is B. x≤-3.
This seems an exponential function.
Once you state that the function is exponential you can write is this form:
f(x) = A * b^x.
Then you need the y-intercept (i.e. x = 0) to find A
f(0) = A * b^0 = A
Once you have A, you can use the ordered pair (3,1) to find b
f(1) = A*b^2 = A*b = 3 => b = 3/A.
With that procedure you can find the function that represents the given graph.
Suppse the y-intercep is 0.1
Then f(0) = A = 0.1
And b = 3 / A = 3/0.1 = 30
And the function is f(x) = 0.1* 30^x
Answer:
A) Median: 7
Mode: 8
Range: 5
B) Tyler is wrong, the greater the MAD value, the greater the variability
Step-by-step explanation:
A) Given the data set: 4,6,6,7,7,8,8,8,9
The median is 7 (the middle point in the ordered list)
The mode is 8 (the most repeated number)
The range is 5 (the difference between the highest and lowest values)
