Answer:
Domain: -5, -2, 1, 5
Range: 10, 11, 4, 10
To get the function, you need to create an equation.
Step-by-step explanation:
For example, f(x)= 10x. "x" equals your y value, and "10" is where you plug in your range, or in other words, your y-values.
Since the pentagon is regular, the sides are all of equal length. This tells you
... 5x-27 = 2x-6
... 3x = 21 . . . . . . . add 27-2x
... x = 7
The length of a side can be found by subtituting this value into either expression.
... 2·7-6 = 8 . . . . inches
The sum of the probabilities in a probability distribution is always 1.
A probability distribution is a collection of probabilities that defines the likelihood of observing all of the various outcomes of an event or experiment. Based on this definition, a probability distribution has two important properties that are always true:
Each probability in the distribution must be of a value between 0 and 1.
The sum of all the probabilities in the distribution must be equal to 1.
An example: You could define a probability distribution for the observation for the number displayed by a single roll of a die. The probability that the die with show a "1" is
1
6
.
That's because there are six possible outcomes, and only one of those outcomes is a "1". Lets label the probabilities of all the possible outcomes for the single die.
Roll a "1": Probability is
1
6
Roll a "2": Probability is
1
6
Roll a "3": Probability is
1
6
Roll a "4": Probability is
1
6
Roll a "5": Probability is
1
6
Roll a "6": Probability is
1
6
Each probability is between 0 and 1, so the first property of a probability distribution holds true. And the sum of all the probabilities:
1
6
+
1
6
+
1

=

,
so the second property of a probability distribution holds true.
Answer:
42+t
q×10 or Q(10)
x+4
1/2y
Step-by-step explanation:
there are 42 members and their combined total would be the answer
Q is the number of members now, 10 is what you need to times it by in order to get the original number of members
the sister is 4 years younger than her brother, therfor he must be 4+ older than her
half of Y would be 1/2Y
