Answer:
-1/3
Step-by-step explanation:
Slope is rise over run. Every 3 units to the left, it rises 1 unit, so the slope is -1/3.
Petri dish A has 1080000000000000
Petri dish B has 270000000000
Petri dish a is greater by 1.07973E15

Answer:- A) U= { keys on a keyboard}
Explanation:-
- A set is a well defined collection of objects.
- A Universal set is the set containing all objects and all other sets are subsets of the universal set. It is denoted by 'U'.
Given set : S = {x,y,4,9,?}
Clearly it contains numbers (4,9), alphabets(x,y) and punctuation mark(?).
Thus the universal set of the given set must contain all of them.
Thus U={keys on a keyboard}

Answer: Choice B) real and integer</h3>
Explanation:
The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically its the set of positive and negative whole numbers, including 0 as well. The set of whole numbers is {0, 1, 2, 3, 4, ...} so any positive number that does not a fractional or decimal part. The value 0 is included in the set of whole numbers. The natural numbers is {1, 2, 3, 4, ...} so it is the set of whole numbers but we kicked out 0 from this set. The set of natural numbers is also called the set of counting numbers.
If we take any two integers and divide them then you'll get a rational number. You cannot have zero in the denominator, but you can have any other integer. For example, 2 and 3 divide to get the fraction 2/3 which is a rational number. Numbers that we cannot express as a fraction of two integers are said to be irrational. An example of this is pi = 3.14 which is irrational. We cannot write pi as a ratio of two integers. One approximation is pi = 22/7, but this doesn't represent pi exactly. Any integer itself is rational. Something like -13 can be written as -13/1, so we cannot say -13 is irrational. That rules out choice A. Choice C is ruled out because negative numbers aren't natural numbers. The same can be said about -13 not being part of the whole number set {0, 1, 2, 3, 4, ...} so choice D is also false.
Answer:
$
Step-by-step explanation:
Use the compound-interest formula:

Where:
FV=Future value or the ending amount
PV=Present value or the initial amount=750
n=Number of compoundings in any one year=2
t=Total number of years=4
r=interest rate=0.0425
Now, replacing the data in the equation:
