Answer:
There is a difference in mean hand span between male and female if you notice the difference between their averages. 2cm is quite significant
female mean = 19.6 cm and male mean = 21.6 cm
Step-by-step explanation:
a.) There is a significant difference.
take P( Z < ( 19.6 - 21.6) / 1) = P(Z < -2) = 2% probability of assuming that male and female means are the same. too low to think like that.
b.) Differ by 2cm. MAD= Mean Absolute Deviation , MAD within their own data set seem similar
C.) The variability in hand spans among male and female are very similar, since they both have the same MAD = 1.0

Step-by-step explanation:
Angles that add up to 90 are Complementary angles.
Two angles that have a common vertex and a common side but do not overlap are Adjacent angles.
Angles that are opposite each other and have the same measurment are vertical angles.
Angles that add up to 180 are Supplementary angles.

Step-by-step explanation:
-2x - 4 + 5y = 8
-2x + 5y = 8 + 4
-2x + 5y = 12

Answer:
y= (3/4)x+2
Step-by-step explanation:
You know it can't be the 1st or the last because the fraction in the parenthesis is the slope. And between 2nd and 4th... a -2 is going to make it go through 0,-2. Therefore, it can only be y= (3/4)x+2
Now, for a rhombus, all sides are the same length, and the diagonals bisect the vertex they cut, so they cut them in halves, and they also meet at right-angles, and cut each other in halves as well
that means, if the angle is 108, the shorter diagonal will cut that in two equal angles, of 54 each, check the picture below
and since they each other cut in halves where they meet, one side of the shorter diagonal will then be half of 9, or 9/2 or 4.5
since the angle is in degrees, make sure your calculator is in Degree mode
