Answer:
A. F'G' = 3 & G'H' = 5.
Step-by-step explanation:
Translations of any shape will not change the side lengths and will be congruent to the original shape.
Answer: 0.6
-------------------------------------------------------------------------------
To get this answer, subtract the given value (0.4) from 1 to get
1-0.4 = 0.6
The reason why this works is because the event either happens or it doesn't happen. There are no other options. So if
A = event happens
B = event doesn't happen
then P(A)+P(B) = 1 which leads to P(B) = 1-P(A)
We define the variables first:
x = number of male cousins
y = number of females cousins
We write the system of equations:
x + y = 9
x = y-2
We solve the system:
Equation 1:
x + y = 9
(y-2) + y = 9
2y-2 = 9
y = 11/2 = 5.5
Equation 2:
x = 5.5-2
x = 3.5
Answer:
Although physically it does not make sense, mathematically the answer is:
number of male cousins = 3.5
number of females cousins = 5.5
The answer is given by the empirical rule, 68%.
