The sum of the first fifteen terms of the given sequence is 220.

The given sequence can be expressed as: [tex]$2, 8, 14, \dots$[/tex], in which each term is six more than the preceding term. This is an arithmetic sequence, where the common difference between terms is 6. The formula to calculate the sum of the first n terms of an arithmetic sequence is given by [tex]$S_n = \frac{n}{2}(a_1 + a_n)$[/tex], where [tex]$a_1$[/tex] is the first term and [tex]$a_n$[/tex] is the nth term.

In the given sequence, the first term [tex]$a_1$[/tex] is 2 and the 15th term [tex]$a_n$[/tex] is 42. So, plugging these values to the formula gives us, [tex]$S_{15} = \frac{15}{2}(2+42) = \frac{15\times 44}{2} = 220$[/tex].

Therefore, the sum of the first fifteen terms of the given sequence is 220.

Step-by-step explanation:

Your commission for a month in which your sales people sold $1,250,000 in insurance policies is $62500

We know that in order to determine the percentage, we divide the value by the total value and then multiply the resultant by 100.

The formula for the percentage would be,

percent = (number of parts / total number of possible parts) × 100%

Here, for a particular month your sales people sold $1,250,000 in insurance policies.

As we can see that your commission would be 5% of all sales over $1,000,000

Let us assume that your commission for that month be x dollars.

Since 1,250,000 > 1,000,000

We need to find 5 percent of $1,250,000

i.e., x = 5 percent of $1,250,000

Using percentage formula,

x = 1,250,000 × (5/100)

x = 62500

Therefore, your commission will be 62500 dollars.

Step-by-step explanation:

42*2/3=84/3=28

The side x = 9.4 approximately to nearest tenth using the cosine rule.

In trigonometry, the cosines rule relates the lengths of the sides of a triangle to the cosine of one of its angles.

Considering the given triangle, side x is calculated with cosine rule as follows;

a² = b² + c² - 2(b)(c)cosA

x² = 8² + 15² - 2(8)(15)cos33°

x² = 64 + 225 - 240(0.8387)

x² = 289 - 201.2809

x² = 87.7191

x = 9.3658 {take square root of both sides}

With proper application of the cosine rule, we can conclude the value of the side x of the triangle is approximately 9.37 to the nearest tenth.

Answer:

20.2%

Step-by-step explanation:

he relative difference between two values can be calculated using the formula:

Relative Difference = (|V1 - V2| / ((V1 + V2) / 2)) * 100%

where V1 is the first value and V2 is the second value.

For the U.S. per capita consumption of beef, we have V1 = 67.8 pounds in 2000 and V2 = 55.4 pounds in 2016. Plugging these values into the formula, we get:

Relative Difference = (|67.8 - 55.4| / ((67.8 + 55.4) / 2)) * 100%

Relative Difference = (12.4 / 61.6) * 100%

Relative Difference = 0.202 * 100%

Relative Difference = 20.2%

So the relative difference between the U.S. per capita consumption of beef in 2000 and 2016 is 20.2%.

The speed of both the trains would be 400 mph and 450 mph respectively.

The formula to calculate the distance travelled is -

Distance = Speed x Time

Given is that two cities are 1020 miles apart. Two trains simultaneously left these cities heading toward one another. The speed of one train was 10 mph greater than the speed of the other one. In 5 hours, the trains had not met yet and were 170 miles apart.

Let the speed of one train be {x} mph. Then, the speed of the other train would be {x + 10} mph.

Distance covered by both the trains would be -

train { 1 } = 5x                             ... { 1 }

train { 2 } = 5(x + 10)                          ... { 2 }

Now, we can write -

1020 - {5x + 5(x + 10)} = 170

1020 - 170 = 10x + 50

10x = 800

x = 80

Speed of train { 1 } = 400 mph

Speed of train { 2 } = 450 mph

Therefore, the speed of both the trains would be 400 mph and 450 mph respectively.

Step-by-step explanation:

the correct answer is : B and D

There are 15 employees in the office and 5 need to be chosen, so there are a total of (15 choose 5) possible ways to select the employees. This can be calculated using the formula for combinations:

(15 choose 5) = 15! / (5! * 10!) = 3003

Now, we need to find the number of ways that the specific group of you, Diana, Kyle, Nancy, and Arthur can be chosen. This is simply (5 choose 5), since we want to choose all 5 members of the group.

(5 choose 5) = 5! / (5! * 0!) = 1

Therefore, the probability of this specific group being chosen is:

(5 choose 5) / (15 choose 5) = 1 / 3003 ≈ 0.0003

So the probability of you, Diana, Kyle, Nancy, and Arthur being chosen is very low, at approximately 0.0003 or 3 in 10,000. This is because there are many other possible groups of 5 employees that could be chosen from the pool of 15, and all of these groups have an equal chance of being selected.

The value of c in the given question is 77.5.

When something can be seen as a gauge of how important something is to a person or organization, it is frequently seen as a reflection of one's worldview and can help to shape attitudes, decisions, and behaviors. Value is a subjective concept that refers to the word of importance that an individual group of people places on something. It is frequently associated with fundamental beliefs and standards that are accepted by society. Depending on the context of the commands, believe is a relative concept.

The Triangle Angle Sum Theorem, which asserts that the sum of the angles in a triangle equals 180°, must be applied in order to find x. Segment AD cuts angle BAC in half, hence the two angles must be equivalent. In order to solve for x, we can build up the following equation:

180° = angle BAC = (x + 7) + (x + 18)

We can solve this equation by combining like terms and isolating the variable x.

180° = 2c + 25

2c = 155

C = 77.5

the central angle of a circle is equal to the measure of the arc that subtends it.

given BF is the diameter of the circle , then

∠ FCA + ∠ ACB = 180°

∠ FCA + 30° = 180° ( subtract 30° from both sides )

∠ FCA = 150°

The expression "The product of m and n divided by three times their difference" can be written as (m * n) / (3 * (m - n)).

Let's break this down:

"The product of m and n" means you multiply m by n, which is written as "m * n".

"Divided by" means you divide the product by something else. In this case, we're dividing by "three times their difference".

"Their difference" refers to the difference between m and n, which is written as "m - n".

"Three times their difference" means you multiply the difference by 3, which is written as "3 * (m - n)".

So, putting it all together, we have:

(m * n) / (3 * (m - n))

This expression represents the product of m and n, divided by three times their difference.

It's important to note that this expression is undefined when m = n, because in that case, the denominator (3 * (m - n)) would be equal to zero. Division by zero is undefined, so we cannot evaluate the expression when m = n.

The number of rounds that Kate has to run along the perimeter of town to complete  12 miles is 4 rounds.

What is the perimeter of a triangle?

Any two-dimensional figure's perimeter is determined by the space surrounding it. By summing the lengths of the sides, we can determine the perimeter of any closed shape. The perimeter of any polygon is equal to the sum of its side lengths. Considering a triangle, the sum of the three sides equals the perimeter.

Given the town is the shape of a triangle.

The distance covered after running one round around town is equal to the perimeter of the triangle.

The sides of the triangle are 0.7 miles, 1.4 miles and 0.9 miles.

Perimeter = 0.7+0.9+1.4 = 3 miles.

The distance covered in one round = 3 miles.

So the number of rounds required to complete 12 miles = 1/3 * 12 = 4 rounds.

Therefore the number of rounds that Kate has to run along the perimeter of town to complete  12 miles is 4 rounds.

What is rectangle ?

Rectangle can be defined in which the opposite sides are equal and area of rectangle is product of length and breadth.

Given ,

I poured a bowl of cereal in a Tupperware container with the following dimensions (L=9 in, w=6 in, h=3). I want no more than a density of 0.3 cheerios per sq in in my "bowl."

We can start by calculating the surface area of the Tupperware container, which is equal to 2 times the sum of the area of the base and the area of the two rectangular sides:

Area of base = Length * Width = 9 in * 6 in = 54 in²

Area of two rectangular sides = Height * Length = 3 in * 9 in = 27 in²

Surface area = 2 * (54 in² + 27 in²) = 2 * 81 in² = 162 in²

Next, we can find the maximum number of cheerios that can be poured into the bowl by dividing the surface area by the maximum allowed density of 0.3 cheerios per square inch:

Maximum number of cheerios = Surface area / Maximum allowed density = 162 in² / 0.3 cheerios/in² = 541 cheerios

Hence, we can pour no more than 541 cheerios into the bowl while maintaining a density of no more than 0.3 cheerios per square inch.
