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.
what will be number of zeros in the square of the number 100? pls answer fasttttttttttt
Answer:
4
Step-by-step explanation:
The square of 100 means that 100 is being multiplied by itself. So the square of 100 is 100x100 = 10,000
Whenever you multiply a number by a multiple of 10, you simply add the number of 0s onto the end of the original number, so 100 originally has 2 zeros, so multiplying by 100 will add on another 2 zeros.
So, the number 10,000 which is the square of 100 has 4 zeros.

Plane zwv and plane tuv intersect at
Answer:
Option (1)
Step-by-step explanation:
Planes ZWV (shaded side) and plane TUV (Top of the box) are the two sides of the given cube or box in the picture attached,
Common edge of the given planes is side SV.
Common edge or the line where two planes meet is the line of intersection of two planes.
Therefore, line SV will be the line of intersection of the given planes.
Option (1) will be he answer.
In Argentina, a cow on a ranch is expected to need an average of 4200 m2
of grassland for food.
What size does a ranch need to be to feed 4500 cows?
Give your answer in hectares.
The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.
And we are asked to find the total area of their grazing but in hectares. So, we can write:
[tex]1 \: cow = 4200 \: {m}^{2} [/tex]
Then, for 4500 cows:
[tex]4500 \: cows = 4200 \: {m}^{2} \times 4500[/tex]
[tex]4500 \: cows = 18900000 \: m {}^{2} [/tex]
We know that, 1 hectares = 10000 m² = 10⁴ m²
Then let the area of the field be x in hectares:
[tex]1 \: hectare = 10000 \: {m}^{2} [/tex]
[tex]x \: hectare = 18900000 \: {m}^{2} [/tex]
Then, putting them in proportion, We will get:
[tex]x = \dfrac{18900000}{10000} hectares[/tex]
[tex]x = \boxed{ 1890 \: hectares}[/tex]
So, the total area in hectares = 1890 hectares.
And we are done !!

A circle has a radius of 7 inches. What is the area of the circle? Use 3.14 for p.
(Area of a circle = pr2)
Answer:
The answer is
153.86 sq. inchesStep-by-step explanation:
Area of a circle is given by
A = πr²where r is the radius of the circle
From the question
r = 7 inches
So the area of the circle is
A = 3.14(7)²
= 3.14 × 49
We have the final answer as
153.86 sq. inchesHope this helps you
Here, we are given with a circle whose radius = 7 inches, and we are asked to find the area of the circle. Taking value of π = 3.14
We know,
Area of the circle = πr²Here,
π = pi (An irrational number used for curves)r = radius of the circleSo, let's find the area,
➝ Area of the circle = πr²
➝ Area of the circle = 3.14 × 7²
➝ Area of the circle = 3.14 × 49
➝ Area of the circle = 153.86 inch²
Hence, Area of the circle:
[tex] \huge{ \boxed{ \bf{153.86 \: {inch}^{2} }}}[/tex]
And we are done !!

The formula a = m – n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon n. A. n = a + m B. n = m – a C. n = a – m D. n = – m – a
Answer:
n = m - a
Step-by-step explanation:
Given that:
The expression of the formula a = m - n
where;
a = actual cost of an item
m = original price
n = amount of coupon in dollars
The objective is to solve for the amount of the coupon.
In order to determine the amount of the coupon, we need to make n which is the amount of coupons in dollars the subject of the formula from the given expression.
So if a = m - n
a + n = m
n = m - a
For f(x)=2x+1 and g(x)=x^2-7 find (f-g)(x)
Answer:
-x² + 2x + 8
Step-by-step explanation:
Essentially we need to subtract g(x) from f(x):
(f - g)(x) = f(x) - g(x) = (2x + 1) - (x² - 7)
Distribute the negative:
(2x + 1) - x² - (-7) = (2x + 1) - x² + 7
Combine like terms:
2x + 1 - x² + 7
-x² + 2x + 8
Thus, the answer is -x² + 2x + 8.

can you please help me
I'm sorry if this is incorrect, but I think the answer is [tex]-2, \sqrt{5}, 4, 3^2[/tex]
Explanation: A negative number will always be the least. 3 squared is actually 3*3 and that would be 9. The square root of 5 is 2.2360679775 which is less than 4 so that would go in the second place. I hope this makes sense! :)
A hot-air balloon starts 6 feet above the ground and then rises 20 feet each minute.
What equation gives the height h in feet as a function of time t in minutes?
A. h=61
B. h=202
С. h = 204 + 6
D. h=6+ 20
At starting hot-air balloon starts 6 feet.
So, at t = 0 , h = 6 feet.
Now, distance travelled per minute is 20 feet.
So, extra distance travelled in t minutes is 20t feet.
Now,
Total height = Staring height + increase in height w.r.t time.
h = 6 + 20t
Therefore, the height h in feet as a function of time t in minutes is h = 6 + 20t .
Hence, this is the required solution.
