9)The triangles are congruent as they share all sides as seen with the lines (SSS)
10) they are not congruent as they only share 2 sides not all 3
11)they are congruent by using the Angle Side Angle, they share a vertices
12)they are congruent, by using the side angle side
13)They are congruent by using side side side, one is shared between the two
14)they are congruent by using the angle side angle
It is c the volume of the smaller pyramid cannot be determined
Answer:
Step-by-step explanation:
as Area of triangle is=1/2 base*height
Given
area=70
height=h=8
base lenght=?
put values in above formula for unkown
70=1/2 (8*b)
70=4*b
b=70/4
b=17.5 units
Answer:
the populations from which the samples were drawn have different standard deviations
Step-by-step explanation:
Given that the assumption of homogeneity of variance is the same as the assumption of the independent samples t-test which asserted that all comparison groups possess the same variance
Therefore, if the homogeneity of variance assumption is violated in an independent groups t-test, this means "the populations from which the samples were drawn have different standard deviations."
