0056 because 1% is 72 so you know it’s going to have to be less then 72. So to get your percent you divide 40 by 7200 so 40/7200. This will get you .00555556 which I rounded to .0056

The surface you provided has parametric equations given by: r(s, t) = ⟨st, s + t, s - t⟩ The vector r(s, t) represents the position of a point on the surface in terms of two parameters, s and t. As s and t vary, different points on the surface are defined, creating the 3D shape of the surface.

This surface is defined by the parametric equations r(s,t)=⟨st,s+t,s−t⟩, which means that for every combination of s and t, we can get a point on the surface. The three components of the vector r(s,t) give the coordinates of that point in 3D space.
One interesting thing about this surface is that it's defined by a set of parametric equations that are themselves parametric. That is, the equations for r(s,t) include the parameters s and t, which are themselves variables that can take on any value.
Another interesting thing is that this surface is defined by a set of equations that are parametric, but not necessarily in terms of time. In other words, these equations don't necessarily describe the motion of an object through time, but rather describe the relationship between two variables (s and t) that define the surface.
In terms of its shape, the surface defined by r(s,t) has a parabolic profile that opens up in the s and t directions. This means that as s and t increase, the surface curves upward and outward, forming a bowl-like shape.
Overall, this is an example of a parametric surface that can be defined by a set of equations that are themselves parametric. While it may not have any real-world applications, it's an interesting mathematical construct that helps us understand how parametric equations can be used to describe complex shapes in 3D space.

Since our calculated t score of 14.4 is much larger than the cutoff t score of 2.131, we can reject the null hypothesis and conclude that the mean creativity score of the current statistics class is significantly different from the mean creativity score of the rest of the university students.

The null hypothesis in this scenario is that the mean creativity score of the current statistics class is not significantly different from the mean creativity score of the rest of the university students, which is 40.

We can use a one-sample t-test to test this hypothesis, where the test statistic is calculated as:

t = (sample mean - population mean) / (sample standard error)

where the sample standard error is calculated as:

standard error = population standard deviation / sqrt(sample size)

Plugging in the given values, we have:

t = (47 - 40) / (5 / sqrt(16)) = 14.4

To find the cutoff t score at the 5% level of significance with 15 degrees of freedom (16 students - 1), we can use a t-distribution table or a calculator. Using a table, we find that the cutoff t score is 2.131.

Therefore, since our calculated t score of 14.4 is much larger than the cutoff t score of 2.131, we can reject the null hypothesis and conclude that the mean creativity score of the current statistics class is significantly different from the mean creativity score of the rest of the university students.

Answer:

y = 1.5x

Step-by-step explanation:

Charge for 3 pounds of salad is $4.50

Charge per pound is thus 4.5/3 = $1.5

Now, we want to write an equation that can be used to represent the cost of salad y for x pounds of salad

Mathematically, that will be;

y = 1.5x

To convert the given equation x^2 + y^2 + z^2 + 6x - 6y - 2z = -3 into standard form, we need to complete the square for the x, y, and z terms.The center is (x, y, z) = (-3, 3, 1) and the radius is √13.

Rearranging the equation, we have:

x^2 + 6x + y^2 - 6y + z^2 - 2z = -3To complete the square for the x terms, we add (6/2)^2 = 9 to both sides:

x^2 + 6x + 9 + y^2 - 6y + z^2 - 2z = -3 + 9Completing the square for the y terms, we add (-6/2)^2 = 9 to both sides:

x^2 + 6x + 9 + y^2 - 6y + 9 + z^2 - 2z = -3 + 9 + 9

Completing the square for the z terms, we add (-2/2)^2 = 1 to both sides:

x^2 + 6x + 9 + y^2 - 6y + 9 + z^2 - 2z + 1 = -3 + 9 + 9 + 1

Simplifying, we have:

(x + 3)^2 + (y - 3)^2 + (z - 1)^2 = 13Comparing this equation with the standard form, we can see that the center of the sphere is (-3, 3, 1) and the radius is the square root of 13. Therefore, the center is (x, y, z) = (-3, 3, 1) and the radius is √13.

Answer:

(t x 361) - 82 = 98

Step-by-step explanation:

product: multiplication

Decreased: subtraction

The solution set is {-√39/26, √15/26}.

To solve the given equation, we'll use the properties of inverse trigonometric functions and trigonometric identities. Let's break down the solution into steps:

Rewrite the equation using the identity arcsin(x) + arccos(x) = π/2.

By the complementary angle property of trigonometric functions, arcsin(x) + arccos(x) = π/2 for all values of x. Therefore, we can rewrite the equation as:

arcsin(4x) + arccos(x) = π/6

arcsin(4x) + arccos(x) = π/2 - π/3

Apply the property of inverse trigonometric functions.

Using the property arcsin(a) + arccos(b) = π/2, we can rewrite the equation as:

arcsin(4x) = π/2 - π/3 - arccos(x)

arcsin(4x) = π/6 - arccos(x)

Solve for x.

Now, we'll solve for x by taking the sine of both sides:

sin(arcsin(4x)) = sin(π/6 - arccos(x))

4x = sin(π/6)cos(arccos(x)) - cos(π/6)sin(arccos(x))

4x = (1/2)x - (√3/2)√(1 - x^2)

4x - (1/2)x = - (√3/2)√(1 - x^2)

(7/2)x = - (√3/2)√(1 - x^2)

x = - (√3/14)√(1 - x^2)

Thus, the exact solutions for the equation are x = -√3/14 and x = √15/26.

Answer:

ANSWER

GIVEN:

OA= 3x-1 , OC= 5x-3, OD= 6x-5 , BO = 2x+1

AO/OC = BO/OD

[The diagonals of a Trapezium divide each other proportionally]

(3x-1)/(5x-3) =( 2x+1)/(6x-5)

(3x-1) (6x-5) = (5x-3) ( 2x+1)

3x(6x-5) -1 (6x-5) = 2x(5x-3)+1(5x-3)

18x² -15x -6x +5 = 10x² -6x +5x -3

18x² -21x +5 = 10x² - x -3

18x² -10x² -21x + x +5+3 =0

8x² - 20x +8= 0

4(2x² -5x +2) = 0

2x² -5x +2 = 0

2x² -4x -x +2= 0

[By factorization]

2x(x-2) -1(x-2)= 0

(2x-1) (x-2) = 0

(2x-1) = 0 or (x-2) = 0

x = ½ or x = 2

If we put x= ½ in OD , The value of OD is negative.

Hence, the value of is x = 2.

Step-by-step explanation:

The circumcenter of the given triangle with vertices D(-3, 3), E(3, 2), F(1, -4) is (0, 1/2).

We need to find the circumcenter coordinates for the given triangle D(-3, 3), E(3, 2), F(1, -4).

We will use the following steps to find the coordinates of the circumcenter of the triangle given above.

Step 1: Find the midpoint of two sides of the triangle

The midpoint of DE is:

$\left( {\frac{{ - 3 + 3}}{2},\frac{{3 + 2}}{2}} \right) = \left( {0, \frac{5}{2}} \right)$

The midpoint of EF is: $\left( {\frac{{3 + 1}}{2},\frac{{2 - 4}}{2}} \right) = (2, - 1)$

The midpoint of DF is: $\left( {\frac{{ - 3 + 1}}{2},\frac{{3 - 4}}{2}} \right) = ( - 1, - \frac{1}{2})$

Step 2: Find the perpendicular bisectors of the sides.

The equation of the perpendicular bisector of DE is:

y - {5}{2} = -{1}{3}( {x - 0}

The equation of the perpendicular bisector of EF is:

y + 1 = {1}{2}( {x - 2}

The equation of the perpendicular bisector of DF is:

y + {1}{2} = - 3( {x + 1}

Step 3: Find the intersection point of the bisectors; that is, the circumcenter of the triangle.

The intersection point of the bisectors is (0, 1/2).

Therefore, the coordinates of the circumcenter of the triangle are (0, 1/2).

Answer: The circumcenter of the given triangle with vertices D(-3, 3), E(3, 2), F(1, -4) is (0, 1/2).

Yep that's correct XD

To convert 4 hours and 45 minutes to a fraction, we need to first convert the minutes to hours by dividing by 60 and then add the result to the 4 hours.

4 hours and 45 minutes = 4 + 45/60 hours = 4 + 0.75 hours

Now, we can write this as a fraction by expressing the decimal part as a fraction:

4 + 0.75 = 4 + 3/4 = (4*4 + 3)/4 = 19/4

Therefore, 4 hours and 45 minutes is equal to 19/4 when expressed as a fraction in simplest form.

The answer is (B) 4 3/4.

The Margin of error is 0.3 when assuming a 90% confidence level.

It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.

The formula for finding the MOE:

MOE = z score * s/√n

Where   is the z score at the confidence interval

            s is the standard deviation

            n is the number of samples.

here, we have,

It is given that among 320 randomly selected airline travelers, the mean number of hours spent traveling per year is 24 hours and the standard deviation is 2.9.

It is required to find the margin of error when the confidence level is 90%.

We have in the question:

at 90% confidence interval = 1.645 (From the Z score table)

s = 2.9

n = 320

Put the above values in the formula, we get:

MOE = 0.2666

Rounding the nearest tenth:

MOE = 0.3

Thus, The Margin of error is 0.3 when assuming a 90% confidence level.
