Answer:-49.3a-1.62b+65.5
Step-by-step explanation:
Combine Like terms:
-13.5a-35.8a=-49.3a
-34.12b+32.5b=-1.62b
Answer: -49.3a-1.62b+65.5
Answer:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation

And replacing we got:

So then the sample proportion of bare ground spots is 0.792 for this sample
Step-by-step explanation:
We have the following info given from the problem:
represent the random sample selected
represent the number of pots that were bare ground (no vegetation)
And for this case if we want to find the sample proportion of bare ground spots we can use this formula:

And replacing we got:

So then the sample proportion of bare ground spots is 0.792 for this sample
Sorry I would have helped but just now seen this. Hope you got it correct
X = -2
set equations equal and solve
2x+7 = -x+1
collect like terms
3x = -6
divide
x=-2
Solution: The venn diagram will be completed as shown in the given figure.
Explanation:
There are many types numbers. The set of numbers are defined below.
Complex Numbers: The complex are the addition of real and imaginative numbers. it is represented as a+bi, where a is a real number and b is an imaginary number.
Imaginary Numbers: The imaginary numbers are those numbers which are not real numbers. For example
.
Real Numbers: All numbers in the number system( fractional, roots, positive, negative, decimal, etc) are real numbers. For example 2.1 and 5 etc. Real numbers are categorized in two parts rational and irrational numbers.
1) Irrational numbers: The number which can't expressed in the form of are called irrational numbers. For example
and
etc.
2) Rational numbers: The number which can be expressed in the form of are called irrational numbers. For example 5 and -5.2 etc. It is categorized in two parts fractional and integer numbers.
3)Integer numbers: The rational number which has no decimal value is called integer numbers. For example-8,-2, 0, 5,7 and 100 etc.
4) Whole Numbers: The set of all positive integers including 0 is called known as the set of whole numbers.
5) Natural Numbers: All Whole numbers except 0 are known as natural number.
