K-maps, commonly referred to as Karnaugh maps, are visual tools for simplifying digital circuits and Boolean algebraic formulas. In order to make Boolean functions simpler for use in digital electronics, Maurice Karnaugh first presented them in 1953. K-maps are used to consolidate terms with similar values and get rid of extraneous terms in the truth table of a Boolean function. With a grid of cells corresponding to all conceivable combinations of binary input values, the map is a two-dimensional representation of a truth table. Depending on the truth value of the relevant word in the truth table, the cells in the grid are either filled with 0s or 1s.

The fundamental benefit of employing Karnaugh maps is that they give the Boolean expression a visual representation, making it simpler to spot patterns and understand the expression. They can also be used to check the accuracy of the final expression and find flaws in digital circuits. Karnaugh maps can be used to quickly and effectively simplify complicated digital circuits, which cuts down on the time and effort needed for circuit design.

Karnaugh maps are perfect for designing and optimizing digital circuits because they may be used to simplify big or complex Boolean statements. For more effective and efficient results, they can be combined with other digital design tools, such as logic gates.

The required equation of the line passing through (4,2) and parallel to y = 1/2x - 3 is y = 1/2x.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The slope of the given line,
y = 1/2x - 3
m = 1/2

The slope of the parallel lines is always equal

Now, the Equation of the parallel line passing through the point (4, 2) is given as
y - y₁ = m (x - x₁)
y -2 = 1/2(x - 4)
y = 1/2x

Thus, the required equation of the line passing through (4,2) and parallel to y = 1/2x - 3 is y = 1/2x.

Answer: If the service rate is 6 customers per hour, the mean service time can be calculated as 1/6 = 0.1 hours or 6 minutes. The negative exponential distribution is commonly used to model the service time distribution in queuing theory. The cumulative distribution function (CDF) of the negative exponential distribution is given by:

F(x) = 1 - e^(-λx)

where λ = 1/μ, where μ is the mean service time (in this case, μ = 0.1 hours or 6 minutes).

So, the probability that the service time will be less than or equal to 6 minutes can be calculated as:

F(6) = 1 - e^(-0.1 * 6) = 1 - e^(-0.6) ≈ 0.5488

So, the answer is approximately 0.549, which is closest to option (b).

Step-by-step explanation:

Volume of a cylinder = area of end X height =  pi r^2 * h

  r = 4 in    h = 10 in

volume = pi (4)^2 * 10 =    160 pi in^3      or    ~  503 in^3

Answer:

160π in.³

Step-by-step explanation:

Get the circle area then multiply for the height. In the end, devide the result by 3,14 (π).

π* . r²                                  50,24 . 10*
π* . 4²                                 502,40 in.³ (cylinder volume)
50,24 (circle area)            

obs: 502,4 leads you to a non-comma π result, considering π as 3,14. If you round, the correct way will be transforming into 502. But 502/3,14 is equal to 159,87..., infinite non-repetitive numbers.

Result in π = 160π* in.³

r - circle radius

10* - height

π* - 3,14 (Used that way)

Using Hamilton's method of apportioning, 21 salespeople can be assigned in the table in the following order:

2, 5, 6, 8.

The approach that now bears his name was first proposed by Alexander Hamilton. Congress endorsed his approach in 1791, but President Washington rejected it. Later, in 1852, it became widely used until 1911. He starts by calculating the precise number of items that each group needs.

Since in the interested question it's about salesperson assigned, we’ll use the language of shift and hours, so we can determine how many salespersons each shift should get.

Now total no. of customers given = 125 + 305 + 439 + 515

                                                        = 1375

Now total no of salesperson available = 21.

So, the divisor = 1375/21

                        = 65.47

Now using Hamilton's method when we divide the average customers per shift by the divisor, we get the no. of salesperson assigned.

So, the salesperson assigned are:

Morning = 125/65.47

              = 2

Midday = 305/65.47

             = 5

Afternoon = 430/65.47

                 = 6

Evening = 515/65.47

               = 8 (Decimals rounded according to Hamilton's principle)

The unit rate for the speed of Runner A and B is 12 and 15 ft / sec respectively, where Rubber B is faster.

A unit rate means a rate for one of something.

Given that, Two runners are training for their next competitions. Each runner is able to run a certain distance in proportion to the time. The table displays the distance Runner A can run in relation to the time. Meanwhile, the graph on the right displays the distance Runner B can run in relation to time. We need to find the unit rates for both runners,

Runner A =

Unit rate = distance / time

= 54 / 4.5

= 12 ft / sec

Therefore, unit rate for the speed of Runner A is 12 ft / sec

Runner B =

According to graph, the Runner B can run 75 ft in seconds

Unit rate = distance / time

= 75 / 5

= 15 ft / sec

Therefore, unit rate for the speed of Runner B is 15 ft / sec

Since, the speed of Runner B is greater than Runner A therefore, Rubber B is faster.

Hence, the unit rate for the speed of Runner A and B is 12 and 15 ft / sec respectively, where Rubber B is faster.
