Answer:
C. 16
Step-by-step explanation:
The distance between two points on the number line is the absolute value of the difference of their coordinates.
If the coordinates of two points on the number line are a and b, then the distance between the two points is
d = |a - b|
The coordinates here are -9 and 7.
distance = |-9 - 7| = |-16| = 16
Ok, so the bigger box has sides that are multiples of 4.5 inches:
18in * 9in * 4.5in.
in terms of the cubes that go inside them, the bigger box is:
4 box * 2 box * 1 box, so you know that 8 boxes fit inside.
Answer:
Step-by-step explanation:
1) Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
2) Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
For what proportion of groups will at most two of the households have cable tv?
So we want to find this probability:
Answer:
The given table represents a function f(x) = y = 2x+3
The upper graph
Step-by-step explanation:
We will write the equation of the right line in the explicit (slope) form
y = ax+b
We will take two points from the given table
A(-1,1) and B(0,3) and insert their coordinates in the equation y=ax+b and get
A(-1,1) => 1 = (-1)*a+b => -a+b=1
B(0,3) => 3=0*a+b => 3= 0+b => b=3
Now we will insert b=3 in the equation -a+b=1 and get
-a+3=1 => a=3-1 => a=2
Now we will insert a=2 and b=3 in the equation y=ax+b and get
equation of the function
y = 2x+3 = f(x) The upper graph.
Good luck!!!
