An airline records data on several variables for each of its flights, model of plane, amount of fuel used, time in flight,
number of passengers, and whether the flight arrived on time. The number and type of variables recorded are
1 categorical, 4 quantitative (1 discrete, 3 continuous)
O 3 categorical, 2 quantitative (1 discrete, 1 continuous)
O 1 categorical, 4 quantitative (2 discrete, 2 continuous)
2 categorical, 3 quantitative (1 discrete, 2 continuous)
O 2 categorical, 3 quantitative (2 discrete, 1 continuous)
Answer:
The correct option is;
2 categorical, 3 quantitative (1 discrete, 2 continuous)
Step-by-step explanation:
A categorical variable which is otherwise known as a nominal variable is one which can be qualified as belonging to one class or category of objects or the other, depending on its attributes, and not based on order of the classes.
Therefore;
1) The model of the plane, and 2) whether the flight arrived on time, are categorical variable
A quantitative variable is a variable that indicates measurement and therefore, indicates the numerical magnitude of a measurement.
Therefore;
1) Amount of fuel used, 2) Time in flight, 3) The number of passengers are quantitative variables
Quantitative variables can be either discrete or continuous
A discrete quantitative variable is one that has a finite number of possible values or which may have an infinite but countable number of values
Therefore;
1) The number of passengers which is countable and exact is a discrete quantitative variable
A continuous variable is one whose exact or accurate value range is infinite or a variable with a limitless value set such as the range of values between two real numbers
Therefore;
1) Amount of fuel used and 2) Time of flight are continuous quantitative variables.

OA. Visited by several politicians and celebrities, our city's new art gallery raised money for charity.
OB. The new art gallery in our city raised money for charity by the visits of several politicians and celebrities.
OC. To raise money for charity, the new art gallery in our city was visited by several politicians and celebrities.
OD. Several politicians and celebrities visited the new art gallery in our city to raise money for charity.
Answer:
They all have the passive word, "Visited," so that makes everything a bit more complicated. I can see why you asked the question. I'd go with C. Unless it's a trick question and you're supposed to see that or something.
547 and 14 and 7658 - 7000 = 658 - blank = 98 -98 = 0 what is the answer
Solution :
7658 - 7000 = 658 - blank
658 = 658
So here, blank is 0.
547 - 7000 = 658 - blank
-7111 = 658 - blank
Blank = 7769
14 - 7000 = 658 - blank
- 6986 = 658 - blank
Blank = 7644

Answer:
[tex] \boxed{ \bold {\huge{ \text{30 \: cm}}}}[/tex]
Step-by-step explanation:

Width of a rectangle ( w ) = 3 cm
[tex] \star{ \sf{ \underline{ \: \: To \: Find}}}[/tex] :
Perimeter of a rectangle ( P ) = ?
First, finding the length of a rectangle ( l ) :

Length of a rectangle = 12 cm
Now, finding the perimeter of a rectangle having length of 12 cm and width of 3 cm

The graph of y = f(x) is shown below. What are all of the real solutions of f(x)
= 0?
Answer:
x = -8, 0 and 6
Step-by-step explanation:
Graphed function in the picture,
y = f(x)
Solutions of a function are defined by the points on x-axis where the graph intersects or touches.
In the given graph, curve of the function touches the x-axis at x = -8 and crosses the x-axis at x = 0, 6
Therefore, real solutions of the function 'f' will be x = -8, 0 and 6.

Christina is packing different books into boxes. The paperback books weigh 0.8 pounds each. The hardcover books weigh 1.3 pounds each. Christina needs to pack the boxes so that there are at least 20 books in each box, but the boxes cannot weigh more than 30 pounds.
Identify Christina’s set of constraints.
Answer:
P + H ≥ 20
P*0.8 lb + H*1.3 lb ≤ 30lb
Step-by-step explanation:
Let's define H as the number of hardcover books.
Let's define P as the number of paperback books.
Now we have the restrictions:
"... so that there are at least 20 books in each box..."
Then:
P + H ≥ 20 (the total number of books per box is 20 or larger)
"...but the boxes cannot weigh more than 30 pounds."
P*0.8 lb + H*1.3 lb ≤ 30lb (the maximum weight that we can have in the box is 30 pounds)
Then the set of constraints is:
P + H ≥ 20
P*0.8 lb + H*1.3 lb ≤ 30lb
Notice that this system has a lot of possible solutions.
P = 20 and H = 0 is a solution
P = 21 and H = 0 is a solution.
P = 19 and H = 1 is a solution.
etc...
