Answer:
Sample
Step-by-step explanation:
The term that represents the description in the question is called sample.
Take for instance:
- 40 students selected from a class of 100
- 1000 people selected from a population of 100000
In the above descriptions:
40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.
Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.
All these and many more represent sample.
Answer:
108 units
Step-by-step explanation:
We are given that
Length of each office,l=10 units
Breadth of each office=b=8 units
Total number of office=3
We know that
Perimeter of rectangle=
Using the formula
Length of cable for 1 office=
Length of cable required for 3 offices=
units
Hence, the required length of cable=108 units
Answer:
see the explanation
The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75
Step-by-step explanation:
Let
x ---> the number of hot dogs that were sold
y ---> is the number of sodas that were sold
we know that
You sold a total of 90 hot dogs and sodas combined
so
----> equation A
You made a total of $105
so

isolate the variable y
----> equation B
substitute equation B in equation A

solve for x

Find the value of y (equation B)

therefore
The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75
Y = -1/2x + 4
2y = -x + 8
x + 2y = 8: the standard form
