Answer:

Your answer is in of the following questions below in step by step explanation.

Step-by-step explanation:

I.   Logic

Are there "rules" or "laws" that govern proper reasoning?  Can we prove, mathematically, that a particular argument is valid?  To what extent can reasoning be automated?

1.   Statement (proposition):  a sentence that is either true or false, but not both.

Example.  Determine if each of the following sentences is a statement.

a.   5 + 3 = 7    

 

21 / 7 = 3    

 

c.   MIDN Miller is President of the United States    

 

d.  Ah,…the joy of SM242!    

 

e.  He is a midshipman  

 

MIDN Avworo has written C++ programs.    

 

Baltimore is the capital of Maryland.    

 

h.  3 * z < 9  

 

i.   Every even integer greater than 2 is the sum of two primes  

 

j.  This sentence is false.  

 

2.  Compound Statements:  a more complex statement composed of simpler statements.  The truth-value of a compound statement depends on the truth values of the simpler component statements.  The component statements in a compound statement are often referred to as statement variables.

 A compound statement usually consists of statement variables joined by logical connectives.

3.   Logical Connectives:  

Not (negation)  

Mathematical symbol:  ~

~p means "it is not the case that p"  where p is some statement.

Other notations: EMBED Equation.DSMT4  , EMBED Equation.DSMT4  

C++ notation:  

The negation of a statement has the opposite truth-value from the statement.  If p is true, ~p  is false.

The definition of negation is displayed in a truth table

p       ~p

F         T

T         F

And (conjunction)

Mathematical symbol:   EMBED Equation.DSMT4  

EMBED Equation.DSMT4    means “it is the case that p and q are true.”

C++ notation:  

The conjunction of two statements p and q is true when and only when both p and q are both true.

The definition of conjunction is displayed in a truth table

p    q       EMBED Equation.DSMT4  

F    F        

F    T        

T    F        

T    T        

Example

p:    MIDN Berrios is an officer

q:    MIDN

What is the justification for each step in solving the inequality?<br><br> −7(3+8x)+5x≤1−62x
dangina [55]
Distribute -7 because of math
-21-56x+5x≤1-62x
add like terms because you aint chaingin nothing
-21-51x≤1-62x
add 62x to both sides (addition property of equality, where a=a and b=b, a+b=a+b) and also (addative inverse, a+(-a)=0) that turns the -62x to 0
-21+11x≤1
add 21 to both sides (additiona proerty of equality and addativeinverse)
11x≤22
divide both sides by 11 (division property of equality, if a=a and b=b, then a/b=a/b)

Use the formula to evaluate the infinite series. Round to the nearest hundredth if necessary.
bagirrra123 [75]

Answer:

1.25.

Step-by-step explanation:

The common ratio r  is 1/5 and the first term a1 = (1/5)^(1-1) = 1.

Sum to infinity =  a1 / (1 - r)

=  1 / (1 - 1/5)

= 1 / 4/5

= 5/4

= 1.25 (answer)

A store sells both cold and hot beverages. Cold beverages, c, cost $1.50, while hot beverages, h, cost $2.00. On Saturday, drink
ra1l [238]

Answer:

The number of hot beverages sold were 45 and the number of cold beverages sold were 180.

Step-by-step explanation:

Let the number of cold  beverages sold be c

And the number of hot beverages sold be h

According to the question:

c=4\times h...

$ 1.5\times c + 2\times h = Sale of any day

Part1:

For Saturday.

The sale is of $360

then

$ 1.5 \times c + $ 2 \times h =$ 360

Part 2:

Following the method of substitution.

And plugging the values of c=4\times h...in equation where the sales of Saturday is given.

1.5\times c + 2\times h =360

1.5\times 4\times h + 2 \times h =360

6\times h + 2\times h= 360

8\times h=360

Dividing both sides with 8.

h=\frac{360}{8}

h=45

Inserting h=45 in c=4 \times h...

we have c=4\times 45 = 180

So the number of hot beverages sold were 45 and the number of cold beverages sold were 180.
