the crowd at a sporting event is estimated to be 2,500 people. the exact attendance is 2,486 people. what is the percentage error?
Answer:
0.56%
Step-by-step explanation:
Percentage error
[tex] = \frac{2500 - 2486}{2500} \times 100 \\ \\ = \frac{1400}{2500} \\ \\ = 0.56\%[/tex]
The crowd at a sporting event is estimated to be 2,500 people, the exact attendance is 2,486 people, the percentage error is, 0.56%
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
The crowd estimated to be 2,500 people
The exact attendance is 2,486 people
Percentage error = ?
Percentage error = (estimated value- exact value)/estimated value×100
Percentage error = (2,500 - 2,486) /2500×100
= 0.56%
So, the percentage error is 0.56%

A gas station sells unleades regular petrol and preminum charged by station for regular is$1.299
Answer:
a. Assuming gallons of unleaded regular is denoted by r; and unleaded premium by p.
Revenue from one gallon of unleaded regular is $1.299 and from unleaded premium is $1.379.
Revenue function = 1.299r + 1.379p
b. Cost of one gallon of unleaded regular is $1.219 and for unleaded premium is $1.289.
Cost function = 1.219r + 1.289p
c. Total profit = Revenue - Cost
= 1.299r + 1.379p - 1.219r - 1.289p
= 1.299r - 1.219r + 1.379p - 1.289p
= 0.08p + 0.09p
d. If station sells 100,000 gallons of unleaded regular and 40,000 of unleaded premium;
= (0.08 * 100,000) + (0.09 * 40,000)
= 8,000 + 3,600
= $11,600

a professional tennis court is a rectangle that is 120 feet long and 60 feet wide. what is the area of the court? what is the perimeter?
Answer:
The area is 7200 square feet and the perimeter is 360 feet.
Step-by-step explanation:
Formulas (for easier reference):
Area of rectangle: length × width
Perimeter of rectangle: length + width + length + width
We can just apply the formulas.
Area of court = 120 × 60
= 7200 square feet
Perimeter of court = 120 + 60 + 120 + 60
= 360 feet

What do the words coefficient and constant mean in mathematics?
Answer:
Step-by-step explanation:
Coefficients are the numbers that come BEFORE a variable, just as 55 is in the term 55x. Constants are numbers in an equation that never change, unless you add them with another constant. For example, in the equation 34x+55=24, the constants are 55 and 24. The only way that either changes is by subtracting the 55 from the 24.

Two spheres have a scale factor of 1:3. The smaller sphere has a surface area of 16 ft2. Find the surface area of the larger sphere.
Answer:
48ft^2
Step-by-step explanation:
Given that:
Small and large Spheres have a scale factor of 1 : 3
Hence,
Smaller sphere = 1
Larger sphere = 3
Surface area of smaller sphere = 16ft^2
Hence,
Surface area of larger sphere = (3 * 16ft^2) = 48ft^2
What is the approximate area of the circle shown below?
A. 94 cm2
B. 11,310 cm2
C. 2827 cm2
D. 188 cm2
Please help
Answer:
Step-by-step explanation:
we have the diameter =60 cm, the radius is 60/2=30 cm
A circle is 3.14*r^2=2827 cm^2
Answer: C. 2827 cm2
Step-by-step explanation:
The area of a circle is calculated by pir^2; r = the radius
In the diagram, the diameter is provided. The radius is half of the diameter. 60/2 = 30, so the radius is 30 cm.
Plug these values into the formula
A = 3.14*30^2
A = 2827.43, which would round to 2827 cm2

Which input value produces the same output value for
the two functions?
O x=-12
O x=9
O x=-6
Ox=-3
Answer:
-6
Step-by-step explanation:
Took test
At x = -6, both functions have the same output of 3.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Now, We get;
f(x) = 2/3x + 7
when x = -12;
= 2/3(-12) + 7
= -8 + 7
= -1
g(x) = 2x + 15....
when x = -12
= 2(-12) + 15
= -24 + 15
= - 9
When x = -9;
f(x) = 2/3(-9) + 7 g(x) = 2(-9) + 15
= -6 + 7 = -18 + 15
= 1 = -3
When x = -6;
f(x) = 2/3(-6) + 7 g(x) = 2(-6) + 15
= -4 + 7 = -12 + 15
= 3 = 3
Thus, At x = -6, both functions have the same output of 3.
