A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:
80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
Answer the questions to solve the problem.

Simplify the expression 4(2x + 8) using the distributive property.
Answer:
[tex]8x + 32[/tex]
Step-by-step explanation:
[tex]4(2x+8)[/tex]
4 × 2x = 8x
4 × 8 = 32
[tex]8x + 32[/tex]
Simplify the expression 4(2x + 8) using the distributive property.
The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!
Hence, the information sho above we can now solve the equation
4(2x + 8) without any problem.
4(2x + 8) ---> 4 * 2x + 4 * 8 ---> 8x + 32
Therefore, your finnal answer is
8x + 32

Which statement best describes the equation x = 3? A. The equation can not be graphed. B. The equation represents a function, but not a linear function. C. The equation represents a linear function. D. The equation represents a line, but not a linear function.
Answer:
D
Step-by-step explanation:
x=3 is a vertical line intersecting 3 on the x axis parallel to the y axis. it can be shown a a line, but it is not a function. A function must have 1 y value for every x value. Here there is infinite y values for one x value therefore it is not a function, but a line.
The statement which best describes the equation x=3 is statement which is in option d which tells that the equation describes a line but not a linear function.
What is function?A function is relationship between two or more variables expressed in equal to form. In a function each value of x must have a corresponding v value. The value that is entered into function is domain of the function and the value which we are getting is known as codomain of function.
How to identify statement?The given equation is x=3.
1) This statement says that the equation cannot be graaphed but it is incorrect because the line of this equation will be vertical line parallel to y axis.
2) This statement says that the equation represents a function but not a linear function but it is also not correct because in this equation there are infinite values of y for the value of x which is a contradiction of the definition of function.
3) This statement says that the equation represents a linear function but it is also not correct because the equation is not a function then how it is a linear function.
4) This statement says that the equation represents a line but not a linear function. It is true because the graph of this equation is a line and the equation is not a linear function because it is not a function.
Hence the statement which best describes the equation x=3 is statement which is in option d which tells that the equation describes a line but not a linear function.

There are 3/4 as many vanilla cupcakes as chocolate cupcakes in a bakery. If there are 35 cupcakes in the bakery, how many are chocolate?
Answer:
8.75
1/4 of 35=8.75 so about 9
Step-by-step explanation:
Answer:
20 Chocolate cupcakes and 15 vanilla cupcakes.
Step-by-step explanation:
Use c for chocolate cupcakes and v for vanilla cupcakes.
3/4c=v
c+v=35
Use substitution
c+3/4c=35
1 3/4c=35 or 7/4c=35 --> Multiply by reciprocal
c=20
Plug it into an equation
20+v=35
v=15
