Answer:
it is proportional
i can't make the graph, but the table would go
x 0 1 2 3 4 5 6
y 3 4 5 6 7 8 9
and then plot those points on the graph
if you need to label, then x would be labeled weeks and y would be total money saved
area = x^2 - 4x + 3

Answer:
Distance from Earth to Proxima Centauri (in scientific notation) = kilometers
Step-by-step explanation:
We need the conversion between Astronomical Unit and Kilometers.
The conversion is:
1 AU = 1.496*10^8 km
or rounded, given in this problem,
1 AU = km
We need the distance from Earth to Proxima Centauri:
AU * kilometers
When multiplying two numbers in scientific notation, we have to "multiply the coefficients" and "add the exponents".
Lets do this:
Distance from Earth to Proxima Centauri (in scientific notation) = kilometers
Answer:
Therefore,
x = -13 , y = 17 or x = 12 , y = 42
Step-by-step explanation:
First, you have to form equation in terms of x and y. With the given informations, the equations will be :
Next, you have to solve it by substitution :
Answer:
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.
Step-by-step explanation:
Mean for a number of units, which means that the Poisson distribution is used to solve this question.
Poisson Distribution:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Mean:
3 defective for 1000, how many for 50?
3 - 1000
- 50
Applying cross multiplication:
What is the probability that an order of 50 units will have one or more faulty units?
This is:
In which
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.
