This means that the fraction will be 49/7
This can also be written as
Answer:
And then we can find the probability replacing the last result and we got:
Step-by-step explanation:
For this case we have the following density function given:
And we want to find the following probability:
We can find this probability with the complement rule like this:
And we can find the following probability:
And then we can find the probability replacing the last result and we got:
Given:
The table of values is
Number of Students : 7 14 21 28
Number of Textbooks : 35 70 105 140
To find:
The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.
Solution:
The ratio of number of textbooks to number of students are
All the ratios of the two quantities are proportional and equivalent to the unit rate.
Let y be the number of textbooks and x be the number of students, then
Here, k=5.
Hence the rate of change is constant that is 5.
Answer:
1.1×10^-4
Step-by-step explanation:
we move the point from where to in between 1.1 and counts the number of numbers it has crossed..in this case it 4...which should be -4
