"Rate of change" is another name for "slope".
In the table, every time 'x' increases by 2, 'y' also increases by 2.
So the rate of change (slope) of the function in the table is
(change in 'y') / (change in 'x') = 2/2 = 1 .
The rate of change (slope) in the function y = x + 4 is
the coefficient (number before) the 'x'. That's also ' 1 '.
So t<span>he rate of change in the function y = x + 4 is the same as (equal to)
the rate of change of the function represented in the table.</span>
domain is -3,4
Step-by-step explanation:
To answer this you can use proportions.
4 1/2 6%
------- = ----
X 100%
So, 6/4.5=1.3333...
Finally, 100/1.3333... appeoximately gives you 75.
75 hours are needed to restore the boat.
Hope this helped!
Answer:
3rd answer
Step-by-step explanation:
If you look at the translation, each point is moved 6 to the right on the X axis, and down 4 on the y- axis. so, therefore it should be (6,-4)
Answer:
0.2384 = 23.84% probability that 3 were laser printers.
Step-by-step explanation:
The printers will be chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
20 orders means that 
8 were laser printers, which means that 
Sample of 5 means that 
What is the probability that 3 were laser printers?
This is P(X = 3).
0.2384 = 23.84% probability that 3 were laser printers.
