These are the means and standard deviations for examples of heights from two kinds of trees.
table:
tree a - (mean: 25ft) (standard deviation: 5ft)
tree b - (mean: 60 ft) (standard deviation: 12 ft)
select the two true statement.
a. tree a's heights are more spread out than tree b's heights.
b. tree a's heights are less spread out than tree b's heights.
c. tree a has a greater average height than tree b.
d. tree a has a lower average height than tree b.

Line gh passes through points (2, 5) and (6, 9). which equation represents line gh? y = x + 3 y = x – 3 y = 3x + 3 y = 3x – 3

Aplot of land has been surveyed for a new housing development with borders ab, bc, dc, and da. the plot of land is a right trapezoid with a height of 60 feet and an opposite leg length of 65 feet

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
