610 students must be randomly selected to estimate the mean weekly earnings of students at one college.

We have to find our α level, that is the subtraction of 1 by the confidence interval divided by 2.

So: α = (1 - 0.95)/2

      α = 0.025

Now, we have to find z in the Z-table as such z has a p-value of 1 - α .

so, Z = 1.96

Now, find the margin of error M as such,

M = z(σ/√n)

In which  is the standard deviation of the population and n is the size of the sample.

The population standard deviation is known to be $63.

This means that σ = 63

ample mean within $5 of the population mean

This is n for which M = 5.

So, M = z(σ/√n)

5 = 1.96(63/√n)

2.55 = (63/√n)

√n = 24.70

n = 610.4

n ≈ 610

Therefore, 610 students must be randomly selected to estimate the mean weekly earnings of students at one college.

Answer:

Step-by-step explanation:

The value of point farthest from the plane is {Mod-(x + 3y + 4(11 - x² - y²))} / √26 units and the values of x, y, and z for the point is 1/8, 3/8, and 347/32.

What is the distance from a point to a plane?

The length of the perpendicular that is dropped from a point to touch a plane is actually the smallest distance between them.

Distance between point and plane:

The distance from (x₀, y₀, z₀) to the plane Ax +By + Cz + D = 0 is

Distance = {Mod-(Ax₀ +By₀ + Cz₀ + D)} / √(A² + B² + C²)

As given,

Z = 11 - x² - y² and plane x + 3y + 4z = 0.

From formula:

D(x, y, z) = {Mod-(Ax₀ +By₀ + Cz₀ + D)} / √(A² + B² + C²)

Substitute values respectively,

D(x, y, z) = {Mod-(x + 3y + 4z)} / √(1² + 3² + 4²)

D(x, y, z) = {Mod-(x + 3y + 4z)} / √(1 + 9 + 16)

D(x, y, z) = {Mod-(x + 3y + 4z)} / √26

Substitute value of z,

D(x, y, z) = {Mod-(x + 3y + 4(11 - x² - y²))} / √26

For farthest point: Dₓ = 0;

1 - 8x = 0

   8x = 1

    x = 1/8

Similarly, for farthest point: Dy = 0;

3 - 8y = 0

    8y = 3

      y = 3/8

Substitute obtained values of x and y respectively,

z = 11 - x² - y²

z = 11 - (1/8)² - (3/8)²

z = 347/32

So, the farthest points are,

x = 1/8, y = 3/8, and z = 347/32.

Hence, the value of point farthest from the plane is Mod-(x + 3y + 4z)/√26 units and the values of x, y, and z for the point is 1/8, 3/8, and 347/32.

Answer:

Here we do not have the options, so I will answer in a general way.

We have two statements:

p = A number is greater than 25

q = A number is less than 35

We want to have:

p ^ q is true

This means:

p and q are true.

So, we need to find a number such that both conditions are meet, so we need to find a number N such that

The number N is greater than 25  (from p)

The number N is less than 35 (from q)

So N can be any number between 25 and 35

So, some of the possible values of N are:

N = 26

N = 27

N = 28.6

N = 33

N = 34

Concluding, any number N ∈ (25, 35) can be a solution.

(Note that N = 25 and N = 35 are not solutions)

Answer:

 its a geometric sequence where each term is 3 times the previous term.

Step-by-step explanation:

{2,6,18,54,162,486,1458...}

The line integral of $2x^2 \mathrm{~d}y$ along the curve $C$ is equal to 486 according to the given information.

To calculate the line integral $\int_C 2x^2 \mathrm{~d}y$, we need to parameterize the curve $C$ and express $x$ and $y$ in terms of the parameter $t$. The given curve is defined as $\mathbf{r}(t) = \langle 3t-3, 3t \rangle$, where $0 \leq t \leq 4$.

Differentiating $\mathbf{r}(t)$ with respect to $t$, we have $\mathbf{r}'(t) = \langle 3, 3 \rangle$. Integrating $2x^2$ with respect to $y$ along the curve $C$ gives us:

$\int_C 2x^2 \mathrm{~d}y = \int_0^4 2(3t-3)^2 (3 \mathrm{~d}t) = 2 \int_0^4 (27t^2 - 54t + 27) \mathrm{~d}t$.

Evaluating the integral, we get $\int_C 2x^2 \mathrm{~d}y = [9t^3 - 27t^2 + 27t]_0^4 = 486$.

Therefore, the line integral $\int_C 2x^2 \mathrm{~d}y$ along the curve $C$ is equal to 486.

Answer:

y = -5x +7

Step-by-step explanation:

The equation of a line parallel to y = - 5x + 4 and passes through (1, 2) is

y = - 5x + 7.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, a line y = - 5x + 4.

It has a slope of - 5 and we know lines parallel to each other have the same slope.

∴ The slope of the required line is also - 5.

Let, y = - 5x + b is the required line passes through (1, 2),

∴ 2 = - 5(1) + b.

2 = - 5 + b.

b = 2 + 5.

b = 7.

So, y = - 5x + 7.

the area of the trapezium is 126cm ².

Since,

'A trapezium is a quadrilateral, which is defined as a shape with four sides and one set of parallel sides.'

According to the given problem,

AB = FC = 7cm

Perimeter of ABCF = 26cm

CB = FA

⇒ 26 = 7 + 7 + CB + CB

⇒ 12 = 2CB

⇒ CB = 6

Base 1 = CF = 6cm

Base 2 = DEDE = DB + BA + AEDB = AEDE = 14 + 7 + 14 = 35

Area = 1/2 (a + b) h

h = 4a = Base 1 = 7b = DE = 28

The range of the function g(x) = |x - 12| - 2 is {y | y > -2}, indicating that the function can take any value greater than -2.

To find the range of the function g(x) = |x - 12| - 2, we need to determine the set of all possible values that the function can take.

The absolute value function |x - 12| represents the distance between x and 12 on the number line. Since the absolute value always results in a non-negative value, the expression |x - 12| will always be greater than or equal to 0.

By subtracting 2 from |x - 12|, we shift the entire range downward by 2 units. This means that the minimum value of g(x) will be -2.

Therefore, the range of g(x) can be written as {y | y > -2}, which means that the function can take any value greater than -2. In other words, the range includes all real numbers greater than -2.

Visually, if we were to plot the graph of g(x), it would be a V-shaped graph with the vertex at (12, -2) and the arms extending upward infinitely. The function will never be less than -2 since we are subtracting 2 from the absolute value.

If a square pyramid is sliced in a way that the plane cuts in a direction perpendicular to the base but doesn't pass through the vertex, the resulting cross-section will be a trapezoid.

This trapezoid will have one pair of parallel sides and one pair of non-parallel sides.

To understand why the resulting cross-section is a trapezoid, imagine a square pyramid standing on its base. Now, imagine slicing the pyramid horizontally, parallel to the base. The resulting cross-section would be a square.

However, if we change the direction of the slice to be perpendicular to the base, but not passing through the vertex, the resulting cross-section will not be a square. Instead, it will be a trapezoid, with one set of parallel sides corresponding to the base of the pyramid, and the other set of sides corresponding to the slice that was made.

This type of cross-section is commonly seen in architectural and engineering designs, where different shapes need to be created by slicing or intersecting 3D shapes. Understanding the resulting cross-section of different slicing techniques is essential to ensure the proper fit and function of the final product.

a) The probability of all three cubes being the same color is 1/4.  For all three cubes to be the same color, we need to choose either 2 green cubes or 2 yellow cubes from bag 1, and then choose a cube of the same color from bag 2.

- Probability of choosing 2 green cubes from bag 1: (2/3) * (1/2) = 1/3
- Probability of choosing 2 yellow cubes from bag 1: (1/3) * (1/2) = 1/6
The probability of choosing a cube of the same color from bag 2 is 1/2.
So, the probability of all three cubes being the same color is: (1/3) * (1/2) + (1/6) * (1/2) = 1/4.

b) The probability of exactly two cubes being the same color is 2/3. For exactly two cubes to be the same color, we can have either 2 green cubes and 1 yellow cube, or 1 green cube and 2 yellow cubes from bag 1, and then choose any cube from bag 2.

- Probability of choosing 2 green cubes and 1 yellow cube from bag 1: (2/3) * (1/2) = 1/3
- Probability of choosing 1 green cube and 2 yellow cubes from bag 1: (2/3) * (1/2) = 1/3
The probability of choosing any cube from bag 2 is 1.
So, the probability of exactly two cubes being the same color is: (1/3) * 1 + (1/3) * 1 = 2/3.

c)  The probability of all three cubes being different colors is 1/3. For all three cubes to be different colors, we need to choose 1 green cube and 1 yellow cube from bag 1, and then choose any cube from bag 2.

- Probability of choosing 1 green cube and 1 yellow cube from bag 1: (2/3) * (1/2) = 1/3
