Which of the following is not a form of valid evidence in deductive reasoning? A. theorems B. definitions C. properties D. patterns

Answers

Answer 1

Answer: Deductive reasoning is a conclusion that is based on many statements which assumed it to be true. The answer is B. Definitions, definitions is not a valid evidence in deductive reasoning because definition is a statement which gives the exact meaning of a word.

Answer 2

Answer:

The correct answer is:

B) definitions.

Explanation:

Deductive reasoning is a logical process where a conclusion is based on the multiple items that are generally assumed to be true.

Deductive reasoning is also called "top-down logic", proceeding from general terms to a specific conclusion.

Since it is based on things known to be true, we can use theorems, properties and given patterns to help us in deductive reasoning.

How can you quickly calculate 20 percent of any bill amount?

Answers

There are several ways in solving quick the 20% of any bill. One of those ways is by getting first the 10% of the amount then will later on be multiplied by two. Another one is by simply dividing the total bill amount by 5, which also 20% of the total bill amount. Hope this helps.

3x^2+13x+10=0 please help

Answers

I will use the quadratic equation to solve this:
x= -b +(or minus, both) √b² + 4ac
--------------------------------------------
2a
So, your numbers would be: a = 3
b = 13
c = 10
Then, solve: x = -13 +(or minus, both) √169 + 120
--------------------------------------------------
6
= -13 +(or minus, both) 17
------------------------------------
6
So, first do the plus: -13 + 17
--------------
6
= 2/3
Then do the minus: -13-17
------------
6
= 5

Your answer is: 2/3 and 5

Evaluate the expression

Answers

Answer: 85

Step-by-step explanation:

To solve this problem, we want to use the order of operations, or PEMDAS.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

To be more specific, you evaluate the expression in the order from top to bottom. To clarify, it is multiply OR divide, depending on which comes first, left to right. This also applies to add OR subtract.

------------------------------------------------------------------------------------------------------------

20÷(5-3)+5²(3) [solve parenthesis]

20÷(2)+5²(3) [solve exponent]

20÷2+25(3) [solve multiply or divide, left to right]

10+75 [solve add or subtract]

Answer:

Step-by-step explanation:

To evaluate the expression, follow the rule of PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

$20 / (5-3) +5^2(3)$

Solve inside the parentheses first by subtracting 3 from 5.

5-3 = 2

$20 / (2) +5^2(3)$

Next, evaluate the exponent.

5² = 5*5= 25

$20 / 2+25(3)$

Next, multiply 25 and 3.

25 *3 =75

$20 / 2+75$

Then, divide 20 by 2.

20/2=10

$10+75$

Finally, add 10 and 75.

$85$

The expression $20 / (5-3) +5^2(3)$ evaluated is 85.

Raquel and Van live in two different cities. As part of a project, they each record the lowest prices for a gallon of gas at gas stations around their cities on the same day. Raquel’s data reflect a mean price of $3.42 with a standard deviation of 0.07. Van’s data reflect a mean price of $3.78 with a standard deviation of 0.23.Which statement is true about their gas-price data?
A- Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.
B- Van’s data are most likely closer to $3.42 than Raquel’s data are to $3.78.
C- Raquel’s data are most likely closer to $3.78 than Van’s data are to $3.42.
D- Van’s data are most likely closer to $3.78 than Raquel’s data are to $3.42.

Answers

the standard deviation shows the dispersion (how close) of the data. Therefore the correct statement is A:
A- Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.

A is the answer my folks.
