The amount of coverage that you will have on the contents of your home would be = $68,750

The total amount of money that was insured for the house = $125,000

The percentage of insurance that was left for the contents of the house = 55% of insurance.

That is;

= 55/100 × $125,000

= 6875000/100

= $68,750.

Step-by-step explanation:

In mathematics, an n-ary function on X is a function that takes n arguments from X and produces a single output. The number of arguments required by an n-ary function is referred to as its arity. The concept of n-ary functions is widely used in mathematics, computer science, and other fields.

There are many examples of n-ary functions on X. Some of them are discussed below:Example 1: Let f be an n-ary function on X, where X is a set of real numbers. The function f takes n real numbers as input and produces a single real number as output. The function can be defined as follows:

f(x1, x2, …, xn) = x1 + x2 + … + xn

Here, the function f takes n real numbers x1, x2, …, xn as input and produces their sum as output.Example 2: Another example of an n-ary function on X is the Cartesian product.

The Cartesian product of n sets A1, A2, …, An is defined as the set of all n-tuples (a1, a2, …, an) such that ai ∈ Ai for i = 1, 2, …, n. In other words, the Cartesian product is the set of all possible combinations of n elements from the sets A1, A2, …, An. The Cartesian product is denoted by A1 × A2 × … × An.

Example 3: Let f be an n-ary function on X, where X is a set of strings. The function f takes n strings as input and produces a single string as output.

The function can be defined as follows:f(s1, s2, …, sn) = s1 + s2 + … + snHere, the function f takes n strings s1, s2, …, sn as input and produces their concatenation as output.These are some examples of n-ary functions on X. In general, an n-ary function on X can be defined in many different ways, depending on the nature of X and the desired output.

With the help of the given Venn diagram, the answer of n(A∪B) is 44 respectively.

A Venn diagram is a visual representation that makes use of circles to highlight the connections between different objects or limited groups of objects.

Circles that overlap share certain characteristics, whereas circles that do not overlap do not.

Venn diagrams are useful for showing how two concepts are related and different visually.

When two or more objects have overlapping attributes, a Venn diagram offers a simple way to illustrate the relationships between them.

Venn diagrams are frequently used in reports and presentations because they make it simpler to visualize data.

So, we need to find:

A ∪ B

Now, calculate as follows:

The collection of all objects found in either the Blue or Green circles, or both, is known as A B. Its components number is:

8 + 7 + 14 + 6 + 1 + 8 = 44

n(A∪B) = 44

He climbed 3/4 of a mile in 2/3 of an hour.

Now we're getting somewhere.

Speed = (distance) / (time)

Speed = (3/4 mile) / (2/3 hour)

Speed = (3/4) / (2/3)    mile/hour

Speed = (3/4) x (3/2)   mile/hour

Speed = 9/8   mile/hour

Speed = 1 and 1/8   mile/hour

That's Choice-C.

Answer:

Step-by-step explanation:

formula

rate = distance / time

r = d/t

Givens

distance = 3/4 of a mile

time = 2/3 of an hour

Solution

Put the fractions in for d/t

\(\frac{\frac{3}{4} }{\frac{2}{3} }\)

Turn the denominator upside down and multiply the result by 3/4

r  =  3/4 * 3/2 = 9 / 8 miles / hour

Answer  r = 1 1/8 or C

neverminding the jumbled lingo, is simply asking for the equation of the tangent line at that point, it says all tangents, well, there's only one passing there.

we can simply get the derivative of f(x) and take it from there.

\(f(x)=4-x^2+2x\implies \left. \cfrac{df}{dx}=-2x+2 \right|_{x=\frac{3}{2}}\implies -2(\frac{3}{2})+2\implies -1\)

since now we know the slope when x = 3/2, then we can just plug that into its point-slope intercept form, along with the coordinates.

Answer:

The tightened spot is 10 feet away from the foot of the pole.

Step-by-step explanation:

1. Draw the diagram. Notice that the shape of the electric pole and its supporting wire creates a right triangle.

2. We know 2 side lengths already (26ft, 24ft), and we need to find 1 more side length. Therefore, to find the 3rd side length of a right-triangle, utilize Pythagoras' Theorem.

⭐What is the Pythagoras' Theorem?

3. Substitute the values of the side lengths into the equation, and solve for the unknown side length.

Let B= the distance from the tightened spot to the foot of the pole.

\((C)^2 = (A)^2 + (B)^2\)

\(26^2 = 24^2 + B^2\)

\(676 = 576 + B^2\)

\(100 = B^2\)

\(\sqrt{100} = \sqrt{(B)^2}\)

\(10 = B\)

∴ The tightened spot is 10 feet away from the foot of the pole.

Step-by-step explanation:

The standard deviation of the number of toys donated by juniors is greater than that of seniors.

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in variation.

\(\rm \sigma = \sqrt{\dfrac{\Sigma (x_i - \mu)^2}{n}}\)

For the seniors, the mean is given as,

Mean = (5 x 2 + 35 x 2 + .... + 15 x 2) / 10

Mean = 26

Then the standard deviation is given as,

σ = √[(26 - 5)² + (26 - 5)² + (26 - 15)²] / 10

σ = 14.28

For the juniors, the mean is given as,

Mean = (40 x 2 + 25 x 2 + ....... + 40 x 2) / 10

Mean = 26

Then the standard deviation is given as,

σ = √[(26 - 40)² + (26 - 25)² + (26 - 40)²] / 10

σ = 13.19

The standard deviation of the number of toys donated by juniors is greater than that of seniors.

Answer: (5 , 1)

Step-by-Step explanation:

hihi your problem is a system of question y = x-4 and  y = -x+6 okay so  graph them both normally and then find the point where they intersect which is gonna be a coordinate point, and that's your solution !!

y = x-4
the y intersect is going to be 4
the slope is a positive 1 , going up to the right, through the positive quadrant, line is facing to the right

y = -x+6
the y intersect is going to be -6
the slope is going to be a -1 , following up the opposite way the line is going to face the left

once you graph them both you'll see the point of intersection, the solution
make sure you drew your lines very clearly !!!!

the solution is  x = 5 and y = 1 which is also (5 , 1)
