The probability that Gianna will randomly elect a brown pair or a green pair is 0.75 or 75%.

A practical technique to express the likelihood that an event will occur or not is through probability notation. When working with Venn diagrams, set notation is employed, and we use it to accomplish this.

Capital letters and various Greek characters are frequently used while notating events.

It is also possible to express probability as a percentage and it can only range from 0 to 1. The likelihood that event A will occur is frequently expressed as P (A) P(A) P(A)P, left parenthesis, A, right parenthesis.

The P(A/B) formula is written as P(A/B) = P(AB) / P(B), where the symbol denotes the intersection of events "A" and "B."

A basket containing 5 brown pair, 7 green pair, and 4 blue pair of coloured contacts. total pair of coloured contacts in basket =5+7+4=16

Gianna will randomly select,

P(a brown pair or green pair) =

[tex]\dfrac{\text{number of brown or green pair of colored contacts in basket}}{\text{total pair of colored contacts in basket}}[/tex]

= [tex]$\frac{5 + 7}{16}[/tex]

= [tex]$\frac{12}{16}[/tex]

To solve the equation 2x^2 + 5x - 3 = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Where a = 2, b = 5, and c = -3.

Plugging in the values, we get:

x = (-5 ± √(5^2 - 4 * 2 * -3)) / 2 * 2

x = (-5 ± √(25 + 24)) / 4

x = (-5 ± √49) / 4

x = (-5 ± 7) / 4

So, the two solutions are:

x = ( -5 + 7 ) / 4 = (2) / 4 = 1/2

x = ( -5 - 7 ) / 4 = (-12) / 4 = -3

So, the two solutions to the equation 2x^2 + 5x - 3 = 0 are x = 1/2 and x = -3.

Answer:

The answer is B) x = 1/2, -3.

Step-by-step explanation:

The equation 2x^2 + 5x - 3 = 0 can be solved using the quadratic formula, which states that the solutions to a quadratic equation of the form ax^2 + bx + c = 0 are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

where a, b, and c are the coefficients of the equation and ± represents both the positive and negative square root.

In this case, a = 2, b = 5, and c = -3. Plugging these values into the formula gives us:

x = (-5 ± √(5^2 - 4 * 2 * -3)) / (2 * 2)

x = (-5 ± √(25 + 24)) / 4

x = (-5 ± √(49)) / 4

x = (-5 ± 7) / 4

So the two solutions are:

x = (-5 + 7) / 4 = 2 / 4 = 1/2

x = (-5 - 7) / 4 = -12 / 4 = -3

Therefore, the solutions to the equation 2x^2 + 5x - 3 = 0 are x = 1/2 and x = -3, which corresponds to option B) x = 1/2, -3.

The equation of the third plane is 3x - 8y - z = -1.

An equation is a mathematical statement that shows the equality or balance of two expressions. It is represented by an equal sign (=) and consists of variables, numbers, and mathematical operations. Equations are used to describe relationships between different quantities and can be solved to find unknown values. For example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving 2x = 4, and then dividing both sides by 2, giving x = 2.

The equation of the first plane is x + y + z = 2.

The equation of the second plane is 8x + y - 2z = 31.

The equation of the third plane is 3x - 8y - z = -38.

The third plane passes through the point (1, 5, 1) and is perpendicular to the plane 2x + y - 2z = 2 and x + 3z = 4. To find the equation of this plane, we can use the cross product of the normal vectors of the two given planes:

(2, 1, -2) × (1, 0, 3) = (3, -8, -1)

So, the equation of the third plane is 3x - 8y - z = -1.

(0.25 s) = -1.8 m/s ,the numerical value of the vertical velocity of the car at time t = 0.25s, which was found to be -1.8m/s.

Part D:

In order to find the expression for the vertical velocity of the car, we need to use both the chain and product rules of differentiation. The chain rule states that if f(x) is a function of g(x), then the derivative of the function is equal to the derivative of g(x) multiplied by the derivative of f(x). The product rule states that if two functions, f(x) and g(x), are multiplied together, then the derivative of the product is equal to the derivative of f(x) multiplied by g(x) plus the derivative of g(x) multiplied by f(x).

Using the chain rule, we can find the derivative of the position-time equation:

y'(t) = yo'e-21 -yde (a cos(wt) + w sin(wt))

Using the product rule, we can find the derivative of the position-time equation:

v(t) = owyo'e-21 -yde (a cos(wt) + w sin(wt)) cos(wt) sin(wt) + yoe- (cos(wt) + aw cos(wt))

Simplifying the expression, we find:

v(t) = ayo'e-20t -w cos(wt) sin(wt)

Part E:

In order to evaluate the numerical value of the vertical velocity of the car at time t = 0.25s, we need to plug the given values for yo, a, and w into the expression for the vertical velocity.

Substituting the given values into the expression, we find:

v(0.25s) = 0.75e-20(-6.3)cos(6.3*0.25)sin(6.3*0.25)

Simplifying the expression, we find:

v(0.25s) = -1.8 m/s

In this example, we used the chain and product rules of differentiation to find the expression for the vertical velocity-time relationship for the car from its position-time relationship. We then used this expression to evaluate the numerical value of the vertical velocity of the car at time t = 0.25s, which was found to be -1.8m/s.

The point-slope formula can be used to get the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

To get the slope at the position (1, -30), first take the derivative of the function:

f'(x) = (x2 - 9) (x2 - 9)

(x - 4)' = 2x - 9/x - 4

Check the derivative at x = 1 now:

f'(1) = 2(1) - 9/(1) - 4 = -93

The line has a -93 slope.

Now, enter the point-slope formula the point (1, -30) and the slope (-93):

y - (-30) = -93(x - 1) (x - 1)

If we simplify, we get:

y = -93x + 22

As a result, y = -93x + 22 is the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

The point-slope formula can be used to get the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30). According to the point-slope formula, the equation of the line is y - y1 = m for a given point (x1, y1) and slope (m) (x - x1). The specified point in this instance is (1, -30), and the slope of the line may be calculated by calculating the function's derivative and evaluating it at x = 1. The derivative of the function f(x) is 2x - 9/x - 4, which for x = 1 translates to -93. When the point and slope are entered into the point-slope equation, we obtain the result y - (-30) = -93(x - 1), which is abbreviated to y = -93x + 22. As a result, y = -93x + 22 is the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

The vertical line test has been used to determine if a graph accurately depicts a function. If a trendline created across the chart is moved and only ever hits it once, the chart is functional. If the line graph crosses the chart at least once, it is not a function.

The core concept of mathematics' calculus is functions. The functions are special types of relations. A function is a rule that generates a unique outcome for each input x in mathematics. A mapping or transformation in mathematics represents a function. Usually, letters like f, g, and h are used to designate these functions. The domain is the set of all possible values that can be passed into a function while it is specified. The term "range" refers to the whole set of values that the function's output is capable of producing. The co-domain is the set of possible values for a function's outputs.

This statement implies that Mike and Chance were picking apples together and that Chance picked three times as many apples as Mike.

Let's say Mike picked "x" apples. Then, according to the statement, Chance picked 3 times as many apples as Mike, which would be 3x apples.

Let x be the number of apples picked by Mike.

Then, the number of apples picked by Chance would be 3 times that, or 3x apples.

So, the equation can be written as:

x + 3x = total number of apples picked by both Mike and Chance.

Combining like terms, we get:

So the total number of apples picked by Mike and Chance together would be x + 3x = 4x apples.

The zeros of a function can be obtained by factor method, by solving equation or on a graph.

What are zeros of a function?

The values of x for which a function f(x) becomes zero, or f(x)=0, are known as the zeros of the function.

There are 3 different ways by which we can find zeros of a function.

The 3 ways are:

1. By factor method

In order to use this strategy, we must first identify a function's factors. The roots of a function are then obtained by equating the factors with zero.

2. By solving an equation

In some functions, it can be challenging to identify the factors directly. In these situations, we first create an equation by equating the polynomial function with zero. The equation is then resolved. A function's roots are the roots of an equation.

3. On a graph

This is the simplest method for locating a function's zeros. With this approach, we must identify the point at which a function's graph touches or cuts the x-axis (i.e., the x-intercept). The zeros of a function are the locations where the graph cuts or touches the x-axis.

Hence, by these ways we can find the zeros of a function.

The integral, in this case, is the area under the line y = 2x + 15 between x = 0 and x = 10. The diagram for this looks like a trapezoid with the base of 10, the left side y = 15, the right side y = 25, and the height of 10. To calculate the area, we use the formula for the area of a trapezoid, which is (b1 + b2)/2 * h, where b1 and b2 are the lengths of the two bases and h is the height. For this problem, b1 is 0 and b2 is 10, and h is 10, so the area of the trapezoid is (10 + 0)/2 * (2*10 + 15 - 2*0 + 15). This simplifies to (10 + 0)/2 * (35), which is 175.

The statement holds for all positive integers n, and a tree with n nodes contains n-1 edges.

The statement can be proven by induction.

Base case: If a tree has one node, then it has no edges (n = 1, n-1 = 0).

Inductive step: Assume the statement is true for n = k (i.e. a tree with k nodes contains k-1 edges). We prove it is true for n = k+1.

Let T be a tree with k + 1 nodes, and let v be any node in T. Then, since T is a tree, v must have exactly one parent node and k-1 child nodes (or no child nodes at all). Let T' be the subtree of T rooted at v, which has k nodes. By the inductive hypothesis, T' has k-1 edges.

Since v has exactly one parent node, there is exactly one edge connecting it to its parent in T. Thus, T has k-1 + 1 = k edges, which means the statement holds for n = k + 1.

The sixth number in the data is 24.

Mean is an arithmetic average of the data set, and it can be calculated by dividing a sum of all the data points with the number of data points in the data.

Given that, the mean of 6 numbers is 36, we need to find the 6th number if 5 of the numbers are 27, 42, 43, 45, and 35

We know that,

Mean = (sum of observations) ÷ (total number of observations)

Let the sixth number be x,

Therefore,

36 = (27 + 42 + 43 + 45 + 35 + x) / 6

216 = 192 + x

x = 24

Hence, the sixth number in the data is 24.
