Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The percentage of parents that have one child under 18 in their homes is k = 15%
The percentage of parents that have two children is T = 65%
The percentage of parents that have three or more children is Y = 20%
Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as
=> 
=>
If the number begins by being rational, multiplying by 0.5 will not change whether or not it is rational. It will remain rational.
That would include any even number 12 * 0.5 = 6
12 started out as rational, so the answer is rational (6)
Any odd number is also rational
23 * 0.5 = 11.5
23 and 11.5 are both rational.
3.636363636 ... is rational so when multiplied by 0.5 the result will be rational.
1.818181818....
So if we start with something irrational like pi
then pi * 0.5 is not rational.
If you have choices, please list them.
Answer:
JK = 30 .
Step-by-step explanation:
As JMLK is a kite the diagonals bisect each other at right angles so triangle JNK is a right triangle.
JK^2 = 18^2 + 24^2 = 900
JK = 30.
Answer:
y = 5x -56
Step-by-step explanation:
Delta y over Delta x for slope. Plug in x = 0 for y int.
y = 5(0) -56
y = -56
Answer:
its 55
