Answer:

A: The decision may not be a good one, since it is possible that there is a "lurking" variable, such as income, behind both the number of booked overseas vacations and the number of free days people have each year.

Step-by-step explanation:

The correlation coefficient given alone is not sufficient to find out whether the relationship was linear or not. As such there may be a lurking variable and we may therefore have to see the scatter plot diagram to help us know if the relationship was a linear one or not.

The area of the composite figure that is formed from a rectangle and triangle is 100 cm²

The area of the composite figure is the sum of the area of the whole figure.

Therefore, the composite figure can be divided into a triangle and a rectangle.

Hence,

area of rectangle = lw

where

area of the rectangle = 14 × 5 = 70 cm²

area of triangle = 1 / 2 bh

where

Therefore,

area of a triangle = 1 / 2 × 12 × 5

area of a triangle = 30 cm²

area of the composite figure = 30 + 70 = 100 cm²

Answer:

∠U = 31°

Step-by-step explanation:

∠W has an exterior angle next to it, making them supplementary angles. This means they equal 180° together. First, we solve for ∠W:

∠W + 84 = 180

∠W = 96

We know that ∠W is 96°.

We know that the sum of the angles of a triangle is 180°. Knowing that we can solve for ∠U:

96 + 53 + ∠U = 180

149 + ∠U = 180

∠U = 31

Therefore, ∠U = 31°

Answer:

The answer is A) 98.

Step-by-step explanation:

   Rex has to score 98 marks in his fourth exam to obtain a grade A in the course.

Total marks in four exams = 100 + 100 + 100 + 100 = 400

Marks required for an A (90%) in four exams = 90% of 400

                                                                          = [tex]\frac{90}{100}\times 400[/tex]

                                                                          = 360

Rex scores in Ist, 2nd and 3rd exam = 84, 86 and 92

So the score to be obtained in 4th exam for an A = 360 - (84 + 86 + 92)

                                                                                   = 98

       Therefore, Rex has to score 98 marks in 4th exam to get a grade A.

An approximate match

Step-by-step explanation:

The vlookup (vertical lookup) function is a search function in excel used in locating values in an excel table.

The vlookup syntax is written as:

=VLOOKUP(value, table, col_index, [range_lookup])

The range_lookup is an optional parameter which is used to indicate if the search should be for an exact match or approximate match. Since a column, resort fee will be used as a possible additional cost; the search would be required to return an approximate search rather than an exact match in other for the search condition to be adequately implemented.

The type of match to use in a Vlookup() function to assess the resort fee as a possible additional cost for a particular room is

This refers to the possible cost when the Vlookup() function is used as it is used as a search function to find the values which are in a database table.

With this in mind, we can see that the syntax looks like:

Step-by-step explanation:

You divide prices by the number of oz to find out what the price is per ounce

Answer:

Markup is how much to increase prices and markdown is how much to decrease prices. If we are given a markdown percentage, we multiply the percentage with the original price to find how much of a decrease we are getting, then we subtract this difference from the original price to find the marked down price.

Step-by-step explanation:

9514 1404 393

Explanation:

Markup is the name given to the difference between a cost price and a selling price:

  cost price + markup = selling price

Markdown is a name given to the difference between a list price or tag price and the actual selling price.

  list price - markdown = selling price

Markup and markdown are actual currency amounts. Often, sellers relate them to the cost price or the list price using percentages. That is, the percentage markup can be figured as ...

  percent markup = (markup)/(cost price) × 100%

Similarly, the markdown may be expressed as a percentage of the selling price:

  percent markdown = (markdown)/(selling price) × 100%

__

Additional comments

These representations as percentages are often used because a seller is usually interested in having a specific percentage return on money invested. By making the markup a specific percentage of the cost price, that return can be ensured.

Markdown percentages are often important to a buyer. They look for sales that offer a large percentage discount (markdown), sometimes not paying so much attention to the list price.

Answer:

$3200

Step-by-step explanation:

The total area of land is 30 acre. Let x represent the area in acre that corn is planted and y represent the area in acre that wheat is planted. Therefore:

x + y = 30               (1)

Also, the farmer can spend at most $750 on seeds. Corn cost $15 per acre, maize cost $30 per acre. Hence:

15x + 30y ≤ 750      (2)

Also, x and y > 0

The profit is given by the function:

Profit = 100x + 110y

Graphing equation 1 and equation 2 and solving, we get the points:

(10, 20)

Hence the maximum profit is at:

Max profit = 100(10) + 110(20) = $3200

plot 3 - 17i scale by [tex]\sqrt\frac{2}{4}[/tex]. Rotate 45 ° clockwise

The series explains a geometric procedure for calculating plots  3 - 17i, scale 2√2, and rotation 45 clockwise.

A geometric series is an equation that results from adding all the terms in a geometric sequence.

As per the data given in the question,

(3 - 17i)/(2 + 2i)

Now, use the method of rationalization,

(3 - 17i)/(2 + 2i) × (2 - 2i)/(2 - 2i)

(3 - 17i)/8 × (2 - 2i)

= (6 - 6i - 34i - 34)/8

= (-28 - 40i)/8

It will rotate 45° clockwise.
