Answer:
Mean=19.5
Step-by-step explanation:
Mean= (16x1 + 17x4 + 19x4 + 21x1 + 22x2 + 23x1 + 25x1)/14=273/14=19.5
This equation represents a direct variation, for the ratio between y and x is constant~
Answer:
x ≈ 12.96
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 11² = 17²
x² + 121 = 289 ( subtract 121 from both sides )
x² = 168 ( take the square root of both sides )
x =
≈ 12.96 ( to the nearest hundredth )
Answer:
