Answer:
-10°F, -13°F, and -21°F
Step-by-step explanation:
we are looking for a temperature that is less than -8
-10°F, -13°F, and -21°F are all less than -8
Step 1: Put the numbers in order.
1,2,5,6,7,9,12,15,18,19,27<span>Step 2: </span>Find the median (How to find a median).
1,2,5,6,7,9,12,15,18,19,27<span>Step 3: </span>Place parentheses around the numbers above and below the median.
Not necessary statistically–but it makes Q1 and Q3 easier to spot.
(1,2,5,6,7),9,(12,15,18,19,27)<span>Step 4: </span>Find Q1 and Q3
Q1 can be thought of as a median in the lower half of the data. Q3 can be thought of as a median for the upper half of data.
(1,2,5,6,7), 9, ( 12,15,18,19,27). Q1=5 and Q3=18.<span>Step 5: </span>Subtract Q1 from Q3 to find the interquartile range.
18-5=13.

Answer:
2/39
Step-by-step explanation:
You will end up with 12/234
You can simplify it by 6
And then you get 2/39
This is a Logic Problem. So we need to use operators to solve this problem. There are several operators in logic. Operators can be <em>monadic or dyadic</em>. A <em>monadic operator</em> operates on a single simple statement. Other operators will all be <em>dyadic operators </em>because they operate on two simple statements.
So we have the following simple statements:
p: the book is interesting
q: the book has pictures
Thus, let's solve each notation.
First. p ∧ q
<u>Conjunction operator.</u> <span>The conjunction operator creates a compound statement such that in order for the whole statement to be true, <em>each simple statement must be true. </em>
</span><u>Symbol:</u> & (also ∧)
<u>Parts of conjunction:</u> <span>Two simple statements joined by the conjunction symbol.
</span>
<u>Answer:</u>
<span>p ∧ q: The book is interesting and the book has pictures.
</span>Second. p ↔ q
<u>Bi-conditional operator:</u> The bi-conditional operator creates a compound statement such that in order for the whole statement to be true <em>each simple statement has to have the same truth value.</em>
<u>Symbol:</u> ↔
<u>Parts of bi-conditional:</u> Two simple statements joined by the bi-conditional symbol.
<u>Answer:</u>
p ↔ q: The book is interesting if and only if the book has pictures.
Third. p ∨ q
<u>Disjunction operator:</u> The disjunction operator creates a compound statement that is <em>true if either simple statement is true but false if both simple statements are false.</em>
<u>Symbol:</u> ∨
<u>Parts of disjunction: </u>Two simple statements joined by the disjunction symbol
<u>Answer:</u>
p ∨ q: The book is interesting or the book has pictures.
Fourth. p → q
<u>Conditional operator:</u> T<span>he conditional operator creates a compound statement that sets up a condition for something to be true. <em>If the condition is met, the statement is true.</em>
</span>
<u>Symbol:</u> →
<u>Parts of conditional:</u> <span>Two simple statements joined by the conditional symbol. The first simple statement in a conditional is called the </span><em>antecedent</em><span> and the second simple statement is called the </span><em>consequent</em><span>.</span>
<u>Answer:</u>
p → q: If the book is interesting then the book has pictures.
