if the divining rod is completely useless for locating water, what is the probability that the expert will correctly identify (by guessing) both of the cans containing water?

Step-by-step explanation:

let's say x stands for years.

FFR(x) is a function that calculates the number of fast food restaurant after x years.

FFR(x) = 2x + 13

they have 13 fast food restaurants right now (x = 0).

in 4 years (x = 4) they think they will have 21. that is 8 more than now. that means 2 more per year (2×4 = 8). therefore the factor 2 for every year (x).

FFR(4) = 2×4 + 13 = 8 + 13 = 21

Answer:

Step-by-step explanation:

If Ben has 7 hours of lessons with Off Track Biking, we can find the total cost (C) using the formula:

C = 40h + 100

where h is the number of hours of lessons. Substituting h = 7, we get:

C = 40(7) + 100

C = 280 + 100

C = 380

Therefore, Ben pays $380 in total for his 7 hours of lessons with Off Track Biking.

Step-by-step explanation:

The number of ways of obtaining exactly one Democrat is 504

We are choosing 6 committee members, and exactly 1 of them must be a Democrat, which leaves 5 members to be selected from the Republicans. The number of ways to select 5 Republicans from 9 Republicans is 9 choose 5, which is 9! / (5! * (9-5)!).

Therefore, the total number of ways to form a committee with exactly 1 Democrat and 5 Republicans is 4 * (9 choose 5) = 4 * 126 = 504. or

There are a total of 13 members (4 Democrats and 9 Republicans), so the number of combinations that can be chosen is 13C6, or 1716. Since we are looking for a committee with exactly one Democrat, we need to subtract the total number of combinations with no Democrats (9C6, or 84) from the total number of combinations, giving us 1716-84 = 504 ways of obtaining exactly one Democrat.

The fence surrounds a square yard with an area of 64 square meters. We first have to find length of fence and then multiply it by itself.

Given that it took 48 square meters of lumber to build the fence, and the fence is 1.5 meters tall, we can calculate the area of the yard inside the fence. To do this, we need to determine the total length of the fence. If we assume that the fence is built around a square yard, then the length of each side of the yard will be equal to the total length of the fence divided by 4.

Let's call the length of each side of the yard x. Then, the area of the yard inside the fence is x * x, or x^2. The total length of the fence is 4 * x. Since the fence is 1.5 meters tall, the total area of the lumber used to build the fence is 4 * x * 1.5, or 6x. This is equal to 48 square meters, so we have the equation:

6x = 48.

Solving for x,

x = 8.

Therefore, each side of the yard is 8 meters long.

Area of the yard inside the fence = 8 * 8 = 64 square meters.

This means that the fence surrounds a square yard with an area of 64 square meters.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range.

Given:

G(x) =  -10x² + 100x +44

Now solving the Quadratic Equation we have

D = √(100)² - 4(-10)(44)

D = √10000 + 1760

D = √11760

D= 108.44

Now, x= -b ± D/2a

x= -100 ± 108.44 /2(-10)

This system of equations has the ordered pair (4, -6) as its only solution, as the two lines intersect only at that point.

What is the system of equations?

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

To create a system of equations that has one solution, we can write a second equation that intersects with the first equation in exactly one point.

One way to do this is to solve the first equation for y, then substitute the expression for y into a second equation. For example:

3x + y = 6

y = -3x + 6

This system of equations has one solution, as the two lines intersect at exactly one point.

To create a system of equations that has an infinite number of solutions, we can write a second equation that is identical to the first equation:=

3x + y = 6

3x + y = 6

This system of equations has an infinite number of solutions, as the two lines are coincident and overlap exactly.

To create a system of equations that has no solution, we can write a second equation that is parallel to the first equation:

3x + y = 6

3x + y = 8

This system of equations has no solution, as the two lines are parallel and do not intersect.

To create a system of equations that has (4, -6) as its only solution, we can write a second equation that passes through the point (4, -6):

3x + y = 6

y = -3x - 6 + 12

y = -3x + 6

What are the area and perimeter of a rectangle?

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know, The area of a triangle is (1/2)×base ×height and the area of the semicircle is (1/2)πr².

Also, the perimeter of a triangle is the sum of the lengths of all the sides and the perimeter of a semicircle is πr.

From the given figure The right angle triangle is an isosceles therefore, The length of the side BC is also 12 units.

Hence the area is = (1/2)×12×12 = 72 sq cm.

And The area of the semicircle is,

(1/2)×π×(√12² + 12²) sq cm.

= (1/2)×3.14×√(288) sq cm.

The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept.

To find the equation of the line that passes through the point (-1, 3) and has a slope of -3, we can use the point-slope form of a line: y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line.

Substituting the given values, we get: y - 3 = -3(x - (-1))

Expanding the right side, we get: y - 3 = -3x + 3

Adding 3 to both sides, we get: y = -3x + 6

So the equation of the line that passes through the point (-1, 3) and has a slope of -3 is y = -3x + 6.

Hope this helps,

- Jeron :- )

Answer: y=-3x+6

Step-by-step explanation:

The equation for slope intercept form is y=mx+b, and since you are given your y and x values from the point (-1, 3), you can plug those values into it. You are also given your slope of -3, and since m is your slope value, you would plug the -3 in as your m.

After you plug in your given values from the problem, you should should get 3 = -1 (3) + b.

Then, you isolate the b. Multiply the -1 and 3 to get -3.

3 = -1 (3) + b

3 = -3 + b

Next, add the 3 to both sides of the equation, and you should be left with b=6.

3 = -3 + b

+3  +3

--------------

6 =  0 + b

6 = b

Finally, you re-write the slope intercept equation with the y-intercept (b value) you just found along with the slope of -3 given by the problem to get y=-3+6.

Based on the information, it can be inferred that the correct fraction is 8/8 - 3/8 (option B).

To select the correct fraction we must perform the following procedure:

Analyze the fraction that we have as reference. Once we know its elements (numerator and denominator) we can identify any fracture that is related to it.

We analyze the options and identify the one that is related to the reference fraction. In this case the correct fraction would be 8/8 - 3/8 because we leave the same denominator and do the subtraction with the numerators.

So it would be 8 - 3 = 5. So the correct fraction is option B.
