Using mathematical operations, we know that a wooden piece of (B) 4 feet will have the least unused wood.
What are mathematical operations?An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands. The rules that specify the order in which we should solve an expression involving multiple operations are known as the order of operations. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction (from left to right).So, the piece of wood which will have the least amount of unused wood:
The piece of wood Tomas will cut is √11.We know that √11 is 3.313.31 is more than 3 and less than 4.
3 < 3.31 < 4So, wooden pieces of 4 feet will have the least unused wood.

[tex]\begin{gathered} A\text{ die has 6 faces numbered 1,2,3,4,5,6} \\ Therefore,\text{ the number of possible outcomes will be 6} \end{gathered}[/tex]STEP 3: Answer question A
Rolling a number less than 7
[tex]\begin{gathered} Numbers\text{ less than 7}\Rightarrow6,5,4,3,2,1 \\ n(numbers\text{ less than 7\rparen}\Rightarrow6 \\ \\ By\text{ substituting the values into the formula in step 1,} \\ P(Rolling\text{ a number less than 7\rparen}\Rightarrow\frac{6}{6}=1 \\ \\ Percentage\Rightarrow\frac{1}{1}\times100=100\% \end{gathered}[/tex]Hence,
Possible outcomes are 6,5,4,3,2,1
Probability = 1
Probability = 1.0 as decimal
Probability = 100% as percentage
STEP 4: Answer Question B
Rolling an 8
[tex]\begin{gathered} Possible\text{ outcomes}\Rightarrow8 \\ n(8)\Rightarrow0 \\ Probability=\frac{0}{8}=0 \\ Percentage=0\times100\%=0\% \end{gathered}[/tex]Hence,
Possible outcome is 0 since there is no face of the die having 8
Probability = 0
Probability = 0.0 as decimal
Probability = 0% as percentage
STEP 5: Answer Question C
Rolling a number greater than 4
[tex]\begin{gathered} Possible\text{ Outcomes}\Rightarrow5,6 \\ n(Possible\text{ outcomes\rparen}\Rightarrow2 \\ Probability=\frac{2}{6}=\frac{1}{3}\approx0.333 \\ Percentage=\frac{1}{3}\times100=\frac{100}{3}=33.33\% \end{gathered}[/tex]Hence,
Possible outcomes are 5,6
Probability = 1/3
Probability = 0.333 as decimal
Probability = 33.33% as percentage

In anatomy, a student learned that the average resting heart rate is between 60 and 100 beats per minute. The student decided to record the heart rate of people over five minutes while waiting in line at the pharmacy. The dot plot shows the results.
Answers
The correct option regarding the symmetry of the distribution is given as follows:
The data is skewed right, with fewer values on the right end of the graph. The values at 62 and 89 are possible outliers. The data fits within the average of 60 to 100 beats per minute.
How to find the symmetry of the distribution?To find the symmetry of the distribution, the mean and the median need to be calculated and compared, if they are equal or which is greater.
A dot plot shows the number of times that each observation appears in the data-set, hence the complete data-set of heart beats per minute is given as follows:
62, 68, 68, 68, 69, 70, 70, 72, 72, 72, 75, 75, 76, 78, 78, 80, 80, 80, 89, 89.
The mean is the sum of all these observations divided by the number of observations, which is of 20, hence:
Mean = (62 + 3 x 68 + 69 + 2 x 70 + 3 x 72 + 2 x 75 + 76 + 2 x 78 + 3 x 80 + 2 x 89)/20 = 74.55.
The median is the middle value of the data-set, the value which 50% of the observations are less than and 50% are greater than. The cardinality of 20 in this data-set is an even number, hence the median is the mean of the 10th and of the 11th element, as follows:
Median = (72 + 75)/2 = 73.55.
When the mean is greater than the median, as is the case in this problem, the distribution is right skewed, which is the reason for the correct option.

What is the slope of the line that passes through the points (-2, 2) and (-4, -1)?
Write your answer in simplest form.
Answers
The slope of line through points (-2, 2) and (-4, -1) is 3/2 by using the slope-point formula that tells that change in y divided by change in x.
What is slope?A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
What is point?A point is a basic concept in classical Euclidean geometry that represents an exact location in space and has no length, width, or thickness. In contemporary mathematics, a point more broadly refers to a component of a set known as a space.
Here,
The points are (-2, 2) and (-4, -1)
m=(y2-y1)/(x2-x1)
m=Δy/Δx
m=(-1-2)/(-4+2)
m=3/2
By dividing the change in y by the change in x, the slope of the line passing through the points (-2, 2) and (-4, -1) is 3/2.
