The level of measurement of the data is ORDINAL and the data is QUALITATIVE.
An Ordinal level of measurement is one whereby measurement follows a natural order, however, the difference or distance between each category cannot be measured. Ordinal data level are applicable to categorical variables.
In the scenario given,
The different categories available are :
One star, two stars, three stars, four stars and five stars.
The categories are ordered with the number of stars depicting better quality however, the difference between the quality offered isn't measurable.
Qualitative data groups variables into different categories and are used for non - numeric variables.
Quantitative data on the other hand are used for numeric data.
Hence, the level of measurement is Ordinal and the data is QUALITATIVE

Susie divided a 3-pound bag of apples into 2 equal piles. How many pounds of apples are in each pile?
Answer:
1.5 pounds of apples are in each pie
Step-by-step explanation:
to show our work, lets multiply 1.5 by 2.
(this is the distributive property. the method shown in the image is long multiplication, but they follow the same idea)
for the sake of simplicity, we will write 1.5 as 15.
5×2=10
10×2=20
10+20=30
dont forget the decimal point! since we have one digit in the decimal place, we move the decimal behind one digit in 30.
30.0 --> 3.0 or simply, 3.
this proves that there are 1.5 pounds of apples in each pie. hope this goes more in depth !!! :)

Find the Area of a Triangle whose base is 8 inches and height is 5 inches Hint Area = 1/2 bh
Answer:
20
Step-by-step explanation:
This is because If we are looking for arena then we need to multiply the base by the height if we do this then our answer will be 40, but because we are looking at a triangle we will have to devide that by 2. Which will give us the final answer of 20
Answer:
area = 20 inches
Step-by-step explanation:
Area of a triangle = [tex]\frac{1}{2}[/tex] × Base × Height
= [tex]\frac{1}{2}[/tex] × 8 ×5
= [tex]\frac{1}{2}[/tex] × 40
= [tex]\frac{40}{2}[/tex]
= 20
area = 20 inches

Given XZ with X(-4,3) and Z(6.-2), find
the coordinates of Y if Y divides XZ one-fifth
of the way from X to Z.
Answer:
Y = (-2,-4)
Step-by-step explanation:
The ratio would be 1:5
so
1/5(6 - -4) + -4 , 1/5(-2 -3) +3
Endpoints of the segment XZ are [tex]X(x_1,y_1)[/tex] and [tex]Z(x_2,y_2)[/tex].
If a point Y(h, k) divides it in the ratio of m : n.
Then the coordinates of the point Y will be,
[tex](\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})[/tex]
If the endpoints are [tex]X(-4,3)[/tex] and [tex]Z(6,-2)[/tex]and point [tex]Y(h.,k)[/tex] divides the this segment in the ratio of [tex]1:5[/tex].
(h, k) = [tex](\frac{1(6)+(5)(-4)}{1+5},\frac{1(-2)+5(3)}{1+5})[/tex]
= [tex](-\frac{14}{6},\frac{13}{6})[/tex]
= [tex](-\frac{7}{3},\frac{13}{6})[/tex]

x/3=y/8=z/5 và 2x+3y-z=50
Step-by-step explanation:
z = 5y/8
x = 3y/8
2x + 3y - z = 50
6y/8 + 3y - 5y/8 = 50
6y/8 + 24y/8 - 5y/8 = 50
25y/8 = 50
25y = 400
y = 16
x = 3y/8 = 3×16/8 = 3×2 = 6
z = 5y/8 = 5×16/8 = 5×2 = 10

what is 3/11 divided by 2/5 equal?
Answer:
15/22
Step-by-step explanation:
3/11 ÷ 2/5
3/11 x 5/2
3/11 x 5/2 = 15/22
3/11 divided by 2/5 is equal to 15/22.
Here, we have,
To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of a fraction is obtained by flipping the numerator and denominator.
Let's calculate 3/11 divided by 2/5:
(3/11) ÷ (2/5)
To divide, we multiply by the reciprocal:
(3/11) * (5/2)
Now, multiply the numerators together and the denominators together:
(3 * 5) / (11 * 2) = 15/22
Therefore, 3/11 divided by 2/5 is equal to 15/22.

The sum of 3 numbers is 1305. The first number is 360. The second
number is twice the first number. What is the third number?
Answer:
225
Step-by-step explanation:
x + y + z = 1305
x = 360
y = 360×2 = 720
z = 1305 - 360 - 720 = 225
Answer:
225
Step-by-step explanation:
since the first number is 360 and the second number is twice the first number meaning it's (360×2) which is 720,you have to add the two and subtract by 1305 to find the value of the third number(which I have represented by x)
360+720+x=1305
1080+x=1305
x=1305-1080
=225
therefore the third number is 225,you can prove it by adding the three to see whether you will get 1305.

Two jets leave an airbase at the same time and travel in opposite directions, One jet travels 71mi/h faster than the other. If two jets are 7014 miles apart after 6 hours what is the speed of each jet?
jet1 = 549 mi/h
jet2 = 620 mi/h
x= jet1
x + 71 = jet2
6 hours
6 * x
6 * x + 71
6x + 6x + 426 = 7014
12x = 7014 - 426
12x = 6588
x = 6588/12
x= 549
x + 71 = 620

It might be helpful to remember that an exponent signifies repeated multiplication.
a·a·a = a³ . . . . . . 'a' is a factor 3 times, so the exponent is 3.
Similarly, ...
(a³)² = (a³)·(a³) = (a·a·a)·(a·a·a) = a⁶

The mean number of guests on 5 nights is 90. When an extra night of guests is added the mean is 91 . What was the number of guests on the extra night ?
Answer:
96
Step-by-step explanation:
The mean number of 5 nights is 90. It means that the quantity of guests who came these nights is 90*5=450
The mean number of the six nights is 91. So the quantity of guests is 6*91=546
546-450= 96- the quantity of guests that came on the extra night
