Really
just calculate the slope
slope is (y2-y1)/(x2-x1)
for x=0, y=1
for x=1, y=3
slope=(y1-y1)/(x-x1)=(3-1)/(1-0)=2/1=2
answer is 2
Answer:
Step-by-step explanation:
The given expression : [Taking as common outside]
We can see that the greatest common factor (GCF) of the numerator and denominator of given the rational expression =
Answer:
The probability that a worker makes between $400 and $450 is .3413 using the calculator and .34 using the empirical rule.
Step-by-step explanation:
There are two ways to approach this problem.
The first way is to find the <u>z-score</u> corresponding to $400 and $450 weekly wage and find the p-value in between these values.
If you use the normalcdf function on your calculator and put 0 and 1 as the lower and upper bounds, respectively, you will get an area of .3413.
Another way of looking at this problem is to recognize that the weekly wages given are the mean and one standard deviation above the mean.
We can use the <u>Empirical Rule</u>, <em>68-95-99.7</em>, in order to see that going one standard deviation above the mean would be an area of 68/2 = .34.
I've attached an image that shows you what the normal curve looks like.
Answer:
first option
(8, -1)
Step-by-step explanation:
We have the following system of linear equations
To solve the system multiply the first equation by -5 and then add it to the second equation.
-----------------
substitute in any of the two equations and then solve for x
The answer is the first option
(8, -1)
Answer:
5:5 or 7:3
Step-by-step explanation:
Step-by-step explanation:
If there are 15 red marbles, there'll be 7 blue marbles.
If there are 7 blue marbles, there'll be 3 green marbles.
If we get 2 blue marbles and put 2 green, than things will stay like this:
If there are 5 blue marbles, there'll be 5 green marbles.
If we get 2 green marbles and put 2 green, than things will stay like this:
If there are 7 blue marbles, there'll be 3 green marbles.
