As per the statement the data are qualitative because they don't measure or count anything.
The term measurement in math is known as the process of associating numbers with physical quantities and phenomena.
Here we have the statement the types of food served by restaurants Italian, Chinese, fast, etc.
As we looking into the statement we have identified that the statement is defines the characteristics of the restaurant which is also defines that there is no value for counting in it.
So, this refers the quality of the product instead of quantity.
Which also defined that there is no measurement value in it.

Determine whether the variable is qualitative or quantitative: Explain your reasoning_ State of residence Is the variable qualitative or quantitative? Explain your reasoning a. The variable is quantitative because state of residence describes an attribute or characteristic. b. The variable is qualitative because state of residence describes an attribute or characteristic c. The variable is qualitative because state of residence is found by measuring or counting d. The variable is quantitative because state of residence is found by measuring or counting:
To determine whether the variable is qualitative or quantitative, the reasoning for the following question will be:
a) qualitative, State of residence describes an attribute or characteristic, making the variable qualitative. Because the state of residence can be determined through measurement or counting, the variable is qualitative.
b) quantitative, The state of residence serves as a description of an attribute or characteristic, so the variable is quantitative. Since determining the state of residence requires measuring or counting, the variable is quantitative.
c) qualitative, Your variable will be quantitative if it is something like, say, your age or salary, which is typically something that can be discovered by counting or using mary-screw analysis. However, in this case, the state of residence is obviously a qualitative factor.
d) qualitative, If your variable is something like, say, your age or salary, or if it's something that is typically discovered by counting or Mary, then these kinds of variables are quantitative. But in this case, the state of residence is categorically important for this question.

Tammy is selling tickets for the school jazz band concert. Adult tickets cost $5, and student tickets cost $3. If
Tammy sells a total of 130 tickets and collects $462, how many of each kind ofticket did she sell?
Answer:
36 adult and 94 student tickets
Step-by-step explanation:
x = adult ticket y = student ticket
5x + 3y = 462
x + y = 130
x + y = 130
y = 130 - x
5x + 3y = 462
5x + 3(130 - x) = 462
5x + 390 - 3x = 462
2x + 390 = 462
2x = 72
x = 36
x + y = 130
36 + y = 130
y = 94

Find two positive and two negative angles that are coterminal with the quadrantal angle 0= -540° such that each angle lies between -1080° and 720°.
The two positive angles are
(Use a comma to separate ariswers as needed.)
The two positive coterminal angles are 180° and 540°, the two negative ones are -900° and -180°.
How to find the coterminal angles?
For any given angle A, the family of coterminal angles can be written as:
B = A + n*360°
Where n can be any integer number.
Here we want to find angles coterminal to -540°, so we have the relation:
B = -540° + n*360°
if n = -1 we get:
B = -540° - 1*360° = -900°
if n = 1
B = -540° + 1*360° = -180°
if n = 2
B = -540° + 2*360° = 180°
if n = 3
B = -540° + 3*360° = 540°
These are the 4 coterminal angles on the given range.

Answers:

The range of the function (f+g)(x) = x² - 1 will be ( -1, ∞ ). The correct option is B.
What are a domain and range?The range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f make up this set (x). A function's range is the set of values it can take as input. After we enter an x value, the function outputs this set of values.
Given that the function is f(x) = x²+2x-5. The function g(x) will be calculated by the data given in the table.
x -6 -3 -1 4
g(x) 16 10 6 -4
The function g(x) will be:-
g(x) = mx + c
m = ( 10 - 16 ) / ( -3 + 6 )
m = -6 / 3
m = -2
c = y - mx
c = 10 - 6
c = 4
g(x) = -2x + 4
The function ( f + g)(x) will be:-
( f + g)(x) = f(x) + g(x)
( f + g)(x) = x²+ 2x - 5 - 2x + 4
( f + g)(x) = x² - 1
At x = 0, the value ( f + g)(x) is -1. The range of the function is ( -1, ∞).

When compared to my actual height of 5.5 inches, the wall decal's height is 110 inches.
We've got My height in the image is 3 1/2 inches plus 7/2, which is 3.5 inches.
On the basis of the scale:
20 inches are equal to one inch in a portrait on the wall decal. That is a portrait measurement divided by a 20-inch wall decal. If my real height is 5.5 inches, we must determine the height on the wall decal. Let the wall decal's height be "h inches" even though my height is 5.5 inches. To compute the value of h, write the ratio as 1/20 = 5.5/h.
When we cross multiply,
1× h = 5.5 × 20
h = 110.0

regular milk has 4% butterfat. how many litres of regular milk must be mixed with 90 l of milk with 1% butterfat to have milk with 2% butterfat?
20 litres of regular milk must be mixed with 90 l of milk with 1% butterfat to have milk with 2% butterfat.
From the data given,
Let us assume that the x litres of regular milk which have 4% butterfat is mixed.
The amount of butterfat in 40 L of milk with 1% butterfat will be = (40*.01)=0.4 L
The amount of butterfat in x L of milk with 4% butterfat will be =x *0.04=0.04 x
The amount of butterfat in (40+x) L (when both are mixed) of milk with 2% butterfat will be =(40+x)*(0.02)=0.02(40+x)
Since we are aware that the total quantity of butterfat in each type's individual milk will match the total amount of butterfat in the final milk.
Therefore we can set up the equation which will be like this:
0.4+0.04 x=0.02(40+x)
Now solving the above equation for getting the value of "x"
0.4+0.04 x=0.02(40+x)
=>0.4+0.04x=0.8+0.02x
=>0.04x-0.02x=0.8-0.4

To make milk with 2% butterfat, 20 liters of ordinary milk must be combined with 90 liters of 1% butterfat milk.
Assume that 4% butterfat normal milk in an amount of X litres is combined. 40 L of milk with 1% butterfat will contain (40 x 0.01)=0.4 L of butterfat. In X L of milk containing 4% butterfat, the amount of butterfat is equal to =(X liter) x (0.04)=0.04 X.
When both are combined, (40+X) L of milk with 2% butterfat will contain =(40+X)*(0.02)
=0.02(40+X) grams of butterfat.
We know that the overall amount of butterfat in each type's individual milk will be the same as the total amount of butterfat in the finished milk.
As a result, we may construct the equation, which looks like this:
0.4+0.04X = 0.02(40+X)
To find the value of "X," solve the equation above.
0.4+0.04 X=0.02(40+X)
= 0.4+0.04X=0.8+0.02X
= 0.04X-0.02X=0.8-0.4

970

T
6 ft
1
20 ft
Answer: The wall that Randy is painting is 20 feet long and 6 feet high. The two corners that he is not painting are triangular in shape and are each 6 feet high and 4 feet wide.
So the area of the wall that Randy is going to paint is:
20 ft * 6 ft = 120 sq ft
The area of the two corners that Randy is not painting is:
(1/2) * 4 ft * 6 ft = 12 sq ft
Therefore, the total area that Randy needs to paint is:
120 sq ft - 12 sq ft = 108 sq ft
One gallon of paint will cover 100 square feet.
So Randy will need to purchase 108 sq ft / 100 sq ft/gallon = 1.08 gallons of paint.
Randy will have to purchase 1.08 gallons of paint.
