D. No, because the probability of being left-handed is greater, x must count the number of left-handed adults.

The binomial probability formula can be used to calculate the probability of a certain number of successes (or left-handed individuals) in a given number of trials (100 adults). In order for the binomial probability formula to be used, the trials must be independent, meaning that the selection of one person does not affect the selection of the next one. Since the probability of being left-handed is greater, the binomial probability formula cannot be used in this case and x must count the number of left-handed adults.

Answer:

D. (6,3)

Step-by-step explanation:

To the find which point can be located on the line you will have to find the point-slope form

The formula for point-slope form is y=mx+b

m is slope

b is y-intercept

Since we already know the slope we can just replace it:

y=1/2x+b

Now we need to find the y-intercept

We can do this by distributing them with (4,2)

As you remember in point the digits are in x and y

(x,y) so we can tell that 4 is x and 2 is y

Now we can substitute x with 4 and y with 2

2=1/2(4)+b

Multiply 1/2 and 4

which is 2

2=2+b

Thus b=0

So the slope intercept form is y=1/2x

Now we can substitute the other points:

For (5,2):

2=5/2

Which is incorrect since 2 does not equal 5/2

For (2,3):

3=1/2(2)

Which is

3=1

Which is incorrect since 3 does not equal 1

For (3,4)

4=1/2(3)

Which is

4=3/2

Which is incorrect since 4 does not equal 3/2

For (6,3)

3=1/2(6)

Which is

3=3

Which is correct since 3 does equal to 3

The simplified expression is 2x⁵.

To simplify the expression \(\left(4x^{9/2}\right)\left(\frac12x^{1/2}\right)\), we can multiply the coefficients and combine the variables with the same base.

Multiplying the coefficients: \(4 \times \frac12 = 2\)

Multiplying the variables with the same base:

\($x^{9/2} \times x^{1/2} = x^{\left(\frac92 + \frac12\right)} = x^{10/2} = x^5$\)

The smallest and largest possible values of ||v − w|| are 3 and 11, respectively. The smallest and largest values of v · w are 0 and 28, respectively.

The magnitude of a vector is a measure of its length or size. In mathematics, it is represented by two vertical bars surrounding the vector symbol, for example, ||v||.

In this case, we have two vectors, v and w, with magnitudes ||v|| = 7 and ||w|| = 4.

When the vectors v and w point in the same direction, the magnitude of their difference is at its minimum. In this case, ||v − w|| = ||v|| − ||w|| = 7 − 4 = 3.

On the other hand, when the vectors v and w point in opposite directions, the magnitude of their difference is at its maximum. In this case, ||v − w|| = ||v|| + ||w|| = 7 + 4 = 11.

Next, let's consider the dot product of v and w, also known as the scalar product. The dot product of two vectors is a scalar value that is proportional to the magnitudes of the vectors and the cosine of the angle between them.

The smallest possible value of the dot product of v and w is 0, which occurs when they are orthogonal or perpendicular to each other. The largest value of the dot product of v and w is equal to the product of their magnitudes, which occurs when they are parallel. In this case, the largest value of v · w is v · w = ||v|| * ||w|| = 7 * 4 = 28.

Flip the 3/5 then multiply

6 ° 5/3

Reduce the numbers with the greatest common factor 3

So 2•5

And that's 10

Ans is 10.

The numbers in 6 divided by 3/5 are labeled below:

6 = whole number

3 = numerator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

6 x 5/3 = 30/3

Thus, the answer to 6 divided by 3/5 in fraction form is:

30/3

To make the answer to 6 divided by 3/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

30 / 3 = 10

The answer is rounded to the nearest two decimal points if necessary.

30/3 can be simplified to 10/1.

10/1 is an improper fraction and should be written as 10.

The cost to fill the 8-meter tank is $5,200.

To find the cost to fill a tank with an 8-meter diameter, we can use the concept of similarity between the two tanks.

The ratio of the volumes of two similar tanks is equal to the cube of the ratio of their corresponding dimensions. In this case, we want to find the cost to fill the larger tank, so we need to calculate the ratio of their diameters:

Ratio of diameters = 8 m / 4 m = 2

Since the ratio of diameters is 2, the ratio of volumes will be 2^3 = 8.

Therefore, the larger tank has 8 times the volume of the smaller tank.

If the cost to fill the 4-meter tank is $650, then the cost to fill the 8-meter tank would be:

Cost to fill 8-meter tank = Cost to fill 4-meter tank * Ratio of volumes
                          = $650 * 8
                          = $5,200

Therefore, the cost to fill the 8-meter tank is $5,200.

G.C.F = 2 · x

G.C.F = 2x

Therefore, the greatest common factor of 14x² - 4x is: 2x

The correct standard form of the equation of the parabola is y = 1/4(x - 2)² - 5.

In Mathematics, the standard form of the equation of the directrix lines for any parabola is given by this mathematical expression:

y = a(x - h)² + k.

Where:

Since the directrix is horizontal, the axis of symmetry would be vertical. Based on the graph, we have the following points;

directrix y = -6

Vertex (h, k) = (2, -5)

Focus (h, k + 1/4a) = (2, -4)

k + 1/4a = -4

-5 + 1/4a = -4

1/4a = 1

a = 1/4.

Therefore, the quadratic function (equation) for this parabola is given by;

y = a(x - h)² + k.

y = 1/4(x - 2)² + (-5).

y = 1/4(x - 2)² - 5

a)The expected profit is $4,000. b)The standard deviation for the profit is approximately $4,898.98.

a) To calculate the expected profit, we multiply the profit by the probability of it happening:

Expected profit = Profit * Probability

Given:

Profit = $10,000

Probability = 40% = 0.4

Expected profit = $10,000 * 0.4 = $4,000

Therefore, the expected profit is $4,000.

b) To find the standard deviation for the profit, we need more information about the probability distribution of the profit. If we assume that the profit follows a Bernoulli distribution (with only two possible outcomes: getting the contract or not), we can calculate the standard deviation using the formula:

Standard deviation = √(Probability * (1 - Probability) * Profit^2)

Given:

Profit = $10,000

Probability = 40% = 0.4

Standard deviation = √\((0.4 * (1 - 0.4) * $10,000^2)\)

                = √(0.4 * 0.6 * $100,000,000)

                = √(24,000,000)

                ≈ $4,898.98

Therefore, the standard deviation for the profit is approximately $4,898.98.

For the space curve r(t) = <t, 3θ, 2t²>, we can find the tangent vector T, normal vector N, and binormal vector B at any point on the curve.

To find the tangent vector T, we take the derivative of r(t) with respect to t:

r'(t) = <1, 3, 4t>.

The tangent vector T is obtained by normalizing r'(t) (dividing it by its magnitude):

T = r'(t) / ||r'(t)||,

where ||r'(t)|| represents the magnitude of r'(t).

To find the normal vector N, we take the derivative of T with respect to t:

N = (dT/dt) / ||dT/dt||.

Finally, the binormal vector B is given by the cross product of T and N:

B = T x N.

These vectors T, N, and B provide information about the direction and orientation of the curve at any given point. By calculating these vectors for the space curve r(t) = <t, 3θ, 2t²>, we can determine how the curve changes as t varies.

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = \(\frac{1}{2}\) , then

y = \(\frac{1}{2}\) x + c ← is the partial equation

to find c substitute (5, 1 ) into the partial equation

1 = \(\frac{5}{2}\) + c ⇒ c = 1 - \(\frac{5}{2}\) = - \(\frac{3}{2}\)

y = \(\frac{1}{2}\) x - \(\frac{3}{2}\) ← equation of line

to find the y- intercept , let y = 0 in the equation , that is

\(\frac{1}{2}\) x - \(\frac{3}{2}\) = 0 ( multiply through by 2 to clear the fractions )

x - 3 = 0 ( add 3 to both sides )

x = 3 ← is the x- intercept

from the equation the y- intercept is the value of c , then

y- intercept = - \(\frac{3}{2}\)

Answer:

x = 16
