Answer:
Yes this is true.
Step-by-step explanation:
In a survey of a sample of computer users, 10% said their computer had a malfunction that needed to be repaired by a service technician.
The number 10% is a statistic because it is based on a sample of say x computer users, not the entire population of computer users.
And sample x can be any number like 500 or 600 etc. The entire population is in millions. And, sample is a part of population.
So, the answer is true.
B) difference
C) product
D) quotient
The answer to the problem 5 x (4 + 1) is called a C) product.
Given is an expression 5 x (4+1), we need to tell which mathematical operation dose it shows.
In mathematics, the term "product" refers to the result obtained when two or more numbers are multiplied together.
In this case, the numbers involved are 5 and (4 + 1). The expression (4 + 1) is first evaluated inside the parentheses, which results in 5.
Then, the multiplication is performed: 5 x 5 = 25.
So, the correct answer is C) product.

5 x² + 7 x + 2 =
= 5 x² + 5 x + 2 x + 2 =
= 5 x ( x + 1 ) + 2 ( x + 1 ) =
= ( x + 1 ) ( 5 x + 2 )

Answer:
When we have a rectangle of width W and length L, the area of this rectangle can be calculated as:
A = W*L
In this case we have:
W = x
L = 10/x.
Then the area of the rectangle will be:
A = W*L = x*(10/x) = 10
So the value of x cancels in the equation, which means that we can not find the value of x.
Now, as L = 10/x we can find some restrictions:
if x = 0, we would have L = 10/0
So we can not have x = 0.
And as W = x, this represents a positive measure, we also have that x can not be a negative number.
So the relation:
W = x
L = 10/x
Gives us all the possible combinations of width and length such that the area of the rectangle is exactly 10 square units.
