19/9 because 19/3 times 1/3 is 19/9
Answer:
Table 1 and 2 represent a function
Step-by-step explanation:
Given
<em>Table 1</em>
x 5 10 11
y 3 9 15
<em></em>
<em>Table 2</em>
x 5 10 11
y 3 9 9
<em>Table 3</em>
x 5 10 10
y 3 9 15
Required
Determine which of the tables represent that y is a function of x
For a relation to be a function; the x values must be unique.
In other words, each x value must not be repeated;
Having said that;
Analyzing Table 1
<em>Table 1</em>
x 5 10 11
y 3 9 15
<em></em>
Note that the x rows are unique as no value were repeated;
Hence, Table 1 is a function
<em>Table 2</em>
x 5 10 11
y 3 9 9
Note that the x rows are unique as no value were repeated;
Hence, Table 2 is a function
<em>Table 3</em>
x 5 10 10
y 3 9 15
Note that the x rows are not unique because 10 was repeated twice;
Hence, Table 3 is not a function
Answer:
And we can use the cumulative distribution function given by:
And for this case we can write the probability like this:
And then the final answer for this case would be 
Step-by-step explanation:
For this case we define our random variable X "price of gasoline for a city in the USA" and we know the distribution is given by:
And for this case the density function is given by:
And we want to calculate the following probability:
And we can use the cumulative distribution function given by:
And for this case we can write the probability like this:
And then the final answer for this case would be
Answer:
c = 3/2
Step-by-step explanation:
hello :
3(5-2x)=-4(cx+4)
-6x+15 = - 4 cx-16
-6x+4cx = -16-15 means 6x-4cx=-31
(6-4c ) x = 31
the equation have no solutions when : 6-4c = 0 (you have : 0x=31...false)
-4c=-6
c= -6/-4
c = 3/2
Answer:
16 presents
Step-by-step explanation:
Since you know that one present is 3 cm of tape, if he used a total of 48 cm, you can divide 48 into 3 to get 16 presents.
