Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

Step-by-step explanation:

The answer is the first one because the slope is technically \(\frac{2}{1}\)

Up 2 over 1

Since the slope is positive, the graph goes to the right.

(0, -6) is the y intercept because it intersects the y - axis.

Then you draw those two points and connect them.

Step-by-step explanation:

Number of students should be sampled to be within 0.5 drink of population mean with 95% probability is 617 students.

To determine the sample size required to estimate the population mean with a given level of precision, we can use the formula for the margin of error

Margin of error = Z × (standard deviation / sqrt(sample size))

where Z is the critical value of the standard normal distribution corresponding to the desired level of confidence. For a 95% confidence level, Z is 1.96.

We want the margin of error to be no more than 0.5 drinks, so we can set up the equation

0.5 = 1.96 × (6.3 / sqrt(sample size))

Solving for the sample size, we get

sqrt(sample size) = 1.96 × 6.3 / 0.5

sqrt(sample size) = 24.82

sample size = (24.82)^2

sample size = 617

Step-by-step explanation:

To determine the points of intersection between the curve and the paraboloid, we need to find the values of t that satisfy the equations of both curves.

The curve is defined as r(t) = ti (3t - \(t^2\))k, and the paraboloid is defined as z = \(x^2\) \(y^2\). We can substitute the components of the curve into the equation of the paraboloid to find the points of intersection.

Substituting the values of x, y, and z from the curve into the equation of the paraboloid, we get \((ti)^2\)(3t - \(t^2\))\(^2\) = \((ti)^2\) (3\(t^2\) - 2\(t^3\)). Simplifying the equation, we have \((ti)^2\)(3t - \(t^2\) - 3\(t^2\) + 2\(t^3\)) = 0.

To find the values of t that satisfy this equation, we can set each term equal to zero. Thus, we have three possibilities: ti = 0, 3t -\(t^2\) = 0, and 3\(t^2\) - 2\(t^3\) = 0.

Solving these equations, we find that ti = 0 gives t = 0, 3t - \(t^2\) = 0 gives t = 0 or t = 3, and 3\(t^2\) - 2\(t^3\) = 0 gives t = 0 or t = 1/2. Therefore, the points of intersection between the curve and the paraboloid are (0, 0, 0), (0, 0, 0), (3, 3, 27), and (1/2, 1/2, 1/16).

The value of 3⋅C⋅(2A×B) is 126.00. This is obtained by calculating the cross product of A and B, then taking the dot product with C and multiplying by 3.



To find the value of the expression 3⋅C⋅(2A×B), we need to calculate the cross product of vectors A and B, and then perform the dot product with vector C. Let's break it down step by step.

Vector A = 3.00i^ + 3.00j^ - 3.00k^

Vector B = -3.00i^ + 3.00j^ + 4.00k^

Vector C = 7.00i^ - 7.00j^

Step 1: Calculate the cross product of A and B.

A × B = (3.00i^ + 3.00j^ - 3.00k^) × (-3.00i^ + 3.00j^ + 4.00k^)

The cross product of two vectors can be calculated using the following formula:

A × B = (AyBz - AzBy)i^ + (AzBx - AxBz)j^ + (AxBy - AyBx)k^

Using the given vectors A and B:

A × B = (3.00 * 4.00)i^ + (-3.00 * -3.00)j^ + (3.00 * -3.00 - 3.00 * 3.00)k^

     = 12.00i^ + 9.00j^ - 18.00k^

So, A × B = 12.00i^ + 9.00j^ - 18.00k^

Step 2: Perform the dot product of C and (2A×B).

C ⋅ (2A×B) = (7.00i^ - 7.00j^) ⋅ (2(12.00i^ + 9.00j^ - 18.00k^))

The dot product of two vectors can be calculated by multiplying corresponding components and summing them up:

C ⋅ (2A×B) = 7.00 * 2 * 12.00 + (-7.00) * 2 * 9.00 + 0

          = 168.00 - 126.00 + 0

          = 42.00

Therefore, 3⋅C⋅(2A×B) = 3 * 42.00 = 126.00.

The value of 3⋅C⋅(2A×B) is 126.00.

Answer:

Step-by-step explanation:

The perimeter is the sum of all sides.

AB+AC+CB=75

(2x-9) + (2x+3) + (3x+4) = 75

Combine like terms:

(2x+2x+3x) + (-9+3+4) = 75

7x - 2 = 75

7x = 77

x=11

Replace 'x' with '11' in the above equations to find that:

AB = 2(11) - 9 = 22 - 9 = 13 m

AC = 2(11) + 3 = 22 + 3 = 25 m

CB = 3(11) + 4 = 33 + 4 = 37 m

13 + 25 + 37 = 75 m

Similar triangles can be defined as triangles which are similar either in sides, angles, and both. There theorems  that have been established to help us verify similar triangles and an example is the SSS theorem

Proof: SSS means side-side-side similarity

Answer:

Step-by-step explanation:

If you were to graph this on a coordinate plane, it looks like a log function. It starts at (0, 0) and ends, according to the boundaries given, at x = 8. Because we are to solve for the volume using the shell method, we need x = y equations (which we have, thankfully!) and y intervals. The y-interval is given to us within the problem as 0≤y≤2. If we are to revolve this solid about the line y = 2, the line of rotation is above the solid, so we have to go backwards to get there. That's very important. The formula we need for shells is

\(2\pi\int\limits^2_0 {p(y)h(y)} \, dy\)

where p(y) is the distance between the axis of rotation and the solid, and h(y) is the height of the representative rectangle. Since we are using the shell method, the representative rectangle is parallel to the axis of rotation, so it is 8 units long (or high).

p(y) is the distance from y = 2 to the solid, so p(y) = 2 - y

h(y) is the length of the representative rectangle, so h(y) = 8

and filling in the formula:

\(2\pi\int\limits^2_0 {(2-y)(8)} \, dy\) and simplifying a bit:

\(2\pi\int\limits^2_0 {16-8y} \, dy\)

Integrating we get

\(2\pi[16y-4y^2]\) from 2 to 0. Using the First Fundamental Theorem of Calculus:

\(2\pi[(32-16)-(0)]\) simplifies to

\(2\pi(16)\) which is, finally,

\(V=32 \pi\)

In this exercise we have to use the fundamental calculus theorem to calculate the volume of a rotating cylinder, thus we find that:

\(V=32\pi\)

To determine if a data point is considered an outlier for a data set, we need to calculate the interquartile range (IQR) and use it to define the outlier boundaries. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). The correct option is (B).

We have that Q1 = 9 and Q3 = 17, we can calculate the IQR as follows:

IQR = Q3 - Q1 = 17 - 9 = 8

To identify outliers, we can use the following rule:

- Any data point that is less than Q1 - 1.5 * IQR or greater than Q3 + 1.5 * IQR is considered an outlier.

Using this rule, we can evaluate each data point:

A. 27: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

B. 17: This data point is not an outlier because it is equal to the third quartile (Q3).

C. 3: This data point is less than Q1 - 1.5 * IQR = 9 - 1.5 * 8 = -3. It is considered an outlier.

D. 41: This data point is greater than Q3 + 1.5 * IQR = 17 + 1.5 * 8 = 29. It is considered an outlier.

Therefore, the outliers in the data set are A (27) and D (41).

As for when to use the mean, it is generally recommended to use the mean as a measure of central tendency when the data is symmetric and does not have extreme values.

Therefore, the correct option would be B. When the data is symmetric.
