What is the value of 15/2+I?

Answer:

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur. Mathematically,

Probability = Expected outcome/Total outcome

If the spinner has 10 equally sized sections 5 of which are gray and 5 of which are blue, the total outcome will be equal to 10.

The probability that spinning lands on blue = 5/10

The probability that spinning lands on gray = 5/10

The probability that the first spin lands on gray and the second spin lands on blue is 5/10*5/10 = 25/100

25/100 = 1*25/(4*25) = 1/4

Hence, the probability that the first spin lands on gray and the second spin lands on blue in its simplest form is 1/4

Answer:

A.) Yes. The input and output are both possible.

Step-by-step explanation:

In this problem, a dentist sees patients each day to clean their teeth. So we represent this function as g(x) where:

x: Represents the number of people who saw the dentist.

g(x): Represents the number of teeth cleaned.

So we are given a point that is solution to our function, but what does this point represent? This tells us that the dentist saw 20 patients and cleaned 20 teeth. For example, a volunteer dentist can see more people than a common dentist and it is likely that that volunteer person sees fewer teeth. However, it's very difficult that that dentist finds 20 people with an only tooth each. So this situation is possible, but not realistic in the real world.

Answer:

Perimeter o the rectangle = 16x - 2

Step-by-step explanation:

Perimeter of a rectangle = 2(long+ wide)

Then:

Perimeter = 2((6x-4)+(2x+3))

Perimeter = 2(6x+ 2x + 3 - 4)

Perimeter = 2(8x - 1)

Perimeter = 2*8x + 2*-1

Perimeter = 16x - 2

The solution set includes all real numbers less than -5, and all real numbers greater than 1, but does not include -5 or 1 themselves.

Option D is the correct answer.

We have,

We need to isolate the absolute value |x + 2| on one side of the inequality.

We subtract 7 from both sides.

|x + 2| > 3

Next, we can split this inequality into two separate inequalities, one for when the expression inside the absolute value is positive, and one for when it is negative:

x + 2 > 3

or

- (x + 2) > 3

Solving for x in the first inequality.

x > 1

Solving for x in the second inequality.

-x - 2 > 3

Adding 2 to both sides and multiplying by -1.

x < -5

So the solution set for the inequality |x + 2| + 7 > 10 is the set of all x-values that satisfy either x > 1 or x < -5.

Using interval notation.

(-∞, -5) U (1, ∞)

equation of the line is y=mx +b

Therefore, to find the equation in point-slope form and slope-intercept form would we would plug the point (-8, -12) and the slope 6 at the equation above, so:

-12=6(-8) + b

-12=-48 +b

b=-36

Therefore, y=6x -36

Bruce and Felicia would have a unique solution to the given equation. The value of x that satisfies the equation is 15.

To determine if the equation 6x + 2 = 5x + 17 has a unique solution, we need to check if the variable x has a consistent value that satisfies the equation.

By simplifying the equation, we can see that the equation becomes:

6x - 5x = 17 - 2

Simplifying further, we have:

x = 15

Since the variable x has a specific value, in this case, x = 15, the equation does have a unique solution. When x is substituted with 15 in the equation, both sides are equal.

Answer:

Step-by-step explanation:

1. Adding the numbers of those who study a given subject counts ...

That total is 40 +48 +44 = 132. When we subtract from this the total number of students, we get 132 -80 = 52, the number who study exactly 2 subjects plus twice the number who study all three.

From this, we can subtract the number who study exactly 2 subjects, leaving twice the number who study all three. 52 -32 = 20. So, 10 students study all three subjects.

__

2. Adding the numbers of those who study physics and another subject, we have 20+24 = 44. Subtracting twice the number who study all three gives the total of those how study only two subjects, one of which is physics. That total is 44 -20 = 24. So, of those 32 who study exactly two subjects, the remaining 32 -24 = 8 must be students who study only math and chemistry.

The solution to the nonlinear system of equations is (x, y) = (-3, -2) and (x, y) = (1, 6). These points represent the coordinates where the two equations intersect and satisfy both equations simultaneously.

To solve the nonlinear system of equations:

Equation 1: \(y = -x^2 + 7\)

Equation 2: y = 2x + 4

We can equate the right sides of both equations since they both represent y.

\(-x^2 + 7 = 2x + 4\)

To simplify the equation, we can rearrange it to be in the standard quadratic form:

\(x^2 + 2x - 3 = 0\)

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, let's use factoring:

(x + 3)(x - 1) = 0

From this equation, we get two possible solutions:

x + 3 = 0 => x = -3

x - 1 = 0 => x = 1

Now, we substitute these x-values back into either equation to find the corresponding y-values.

For x = -3:

y = 2(-3) + 4

y = -6 + 4

y = -2

For x = 1:

y = 2(1) + 4

y = 2 + 4

y = 6

The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).

In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.

Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

The rate of change of the angle is approximately 0.00238 radians per foot when a wire of 186 feet is attached.

The subject matter of the math discipline of trigonometry is the relationships and characteristics of triangles as well as the trigonometric functions.

These functions (such as sine, cosine, and tangent) are used to relate the angles of a triangle to the lengths of its sides.

We can use trigonometry to find the angle θ in terms of x:

sin θ = opposite/hypotenuse = 75/x

θ = arcsin(75/x)

dθ/dx = d/dx (arcsin(75/x))

Using the chain rule and the fact that d/dx (arcsin(u)) = 1/√(1-u²) × du/dx:

dθ/dx = -75/√(x²-5625) × (-1/x²)

Simplifying:

dθ/dx = 75x / (x² - 5625)³/₂

Now we can substitute x = 186 and find the rate of change of the angle:

dθ/dx | x=186 = 75(186) / (186² - 5625)³/₂ ≈ 0.00238 radians per foot

The given graph shows that the function is periodic and fluctuates between y = -2 and y = 2. So, the range of the function is [-2,2].

The graph covers one period, which is from x = -3 to x = 3, and then repeats itself indefinitely in both directions. So, the domain of the function is (-∞, ∞).

In general, the domain of a function consists of all the possible input values that the function can take. In this case, since the function repeats itself indefinitely, it can take any input value from negative infinity to positive infinity.

So, the domain is (-∞, ∞). The range of a function, on the other hand, consists of all the possible output values that the function can produce.

In this case, the function oscillates between y = -2 and y = 2, so the range is [-2,2]. The interval notation for the domain is (-∞, ∞) and for the range is [-2,2].

The correct equation that represents the value of the car after 2 years is: V = 28,800(1 - 0.066)².

In mathematics, an equation is a statement that two expressions are equal. An equation consists of two parts: the left-hand side (LHS), which is the expression on the left of the equals sign, and the right-hand side (RHS), which is the expression on the right of the equals sign. The two sides are connected by the equals sign (=). The solution to an equation is the value or set of values of the unknown quantity that makes the equation true. An equation can have one solution, multiple solutions, or no solutions at all. Equations are used extensively in many areas of mathematics, as well as in physics, engineering, economics, and other fields, to model relationships between variables and solve problems.

Here,

Here, OV represents the original value of the car after 2 years, which is the value we are trying to find.

The car depreciates at a rate of 6.6% per year, which means that the value of the car decreases by 6.6% each year. Therefore, the value of the car after 1 year is:

28,800(1 - 0.066) = 26,979.20

To find the value of the car after 2 years, we need to apply the same percentage decrease again to the value after 1 year. Therefore, we multiply the value after 1 year by (1 - 0.066) again:

OV = 26,979.20(1 - 0.066) = 25,334.51

Therefore, the value of the car after 2 years is approximately $25,334.51.
