Answer:
Are there answer choices?
Step-by-step explanation:
Pythagorean Theorem:
a^2 + b^2 = c^2
26^2 + 18^2 = c^2
676 + 324 = c^2
1,000 = c^2
ratio
31.6 = c
Mean: add all the numbers & divide by how many numbers thee are
Median: arrange the numbers from least to greatest then mark off one from each side until you get to the middle number. That is the median
Mode: To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
Range: To find range, find the highest number & subtract the lowest number from it. That number is the range
The answer to this problem is D. 2^4x=2^3x-9
