1=0.012inch

10=0.012x10

10=0.12inch

100=0.012x100

100=1.2inch

1000=0.012x1000

1000=12inch

because if 1 poster has a thickness of 0.012 inch

than you have to multiple the number of posters with 0.012 inch

Answer:   True

Step-by-step explanation:

The term inside the parentheses after the summation sign is

       x-sub-i    minus    x-bar

x-bar is the mean average of all the individual n observations. In statistics, it is usually just called the 'mean' for short.

x-sub-i stands for each individual observation: x-sub-1, x-sub-2, and so on

So that means (x-sub-i   -   x-bar) means the difference we get if we do the subtraction, using x-sub-i as the first term in the subtraction.

For an illustration of this, suppose we have a sequence of 5 observations. Since there are 5 observations, n = 5.

x-sub-1  = 4

x-sub-2 = 7

x-sub-3 = 3

x-sub-4 = 11

x-sub-5 = 5

We obtain the mean by adding all the observations and then dividing by the number of observations, n.

The sum 4+7+3+11+5 = 30 and 30/5 = 6.

So the mean, x-bar, = 6.

Now let's look at all the differences between each observation and x-bar.

In the same order as the observations, we get

4 - 6  = -2

7 - 6  =  1

3 - 6 = -3

11 - 6 = 5

5 - 6  = -1

If we add up all the differences, just like we are doing in the summation homework problem, we have (-2)+1+(-3)+5+(-1) = 0.

It also works if you make x-bar the first term in the subtraction. Either way will work, as long as you are consistent about it from one subtraction to the next.

This is always the case with a mean average, so the summation is assured to be zero.

I hope this helps.

The symbols p,x, and s represent sample statistics.

- p (pronounced "p-hat") is the sample proportion. It is used to estimate the population proportion. It is computed as the number of successes in the sample divided by the sample size.

-x (pronounced "x-bar") is the sample mean. It is used to estimate the population mean. It is computed as the sum of all the values in the sample divided by the sample size.

- s is the sample standard deviation. It is used to estimate the population standard deviation. It measures how spread out the data is in the sample. It is computed as the square root of the sum of the squared deviations from the sample mean divided by the sample size minus one.

These sample statistics are used to make inferences about the corresponding population parameters, which are denoted by Greek letters such as μ (mu) for the population mean and σ (sigma) for the population standard deviation.

Area = 2.1875

Step-by-step explanation:

The formula for area of a rhombus is A = 1/2(d1)(d2), where d1 is one of its rhombus and d2 is the other.  Thus, to find the area, we can plug into the formula 1.75 for d1 and 2.5 for d2 and solve for A:

A = 1/2(1.75)(2.5)

A = 0.875*2.5

A = 2.1875

Simplify the expression

To find a value of N that satisfies the error bound of Error(SN) ≤ 1 × 10^(-9) for the given series, we need to use the error bound formula for the midpoint rule.

The error bound formula for the midpoint rule is given by:

Error(SN) ≤ ((b - a)^3 / (24N^2)) * |f''(c)|

where (b - a) is the interval of integration, N is the number of subintervals, and f''(c) is the second derivative of the function evaluated at some point c in the interval.

In this case, the function to be integrated is f(x) = 16x^(1.5), and we need to find a value of N such that the error bound is less than or equal to 1 × 10^(-9).

Since the function f(x) = 16x^(1.5) is continuous and has a second derivative that exists for all x in the interval of integration, we can proceed with finding the value of N.

To find N, we need to determine the maximum value of |f''(c)| in the interval of integration [a, b].

Differentiating f(x) twice, we get f''(x) = 48x^(0.5).

To find the maximum value of |f''(c)|, we consider the endpoints of the interval [a, b]. Since the function f''(x) = 48x^(0.5) is increasing, the maximum value of |f''(c)| will occur at the endpoint b.

Substituting b = 1 into f''(x), we get f''(1) = 48(1)^(0.5) = 48.

Now, we can plug in the values into the error bound formula and solve for N:

((b - a)^3 / (24N^2)) * |f''(c)| ≤ 1 × 10^(-9)

((1 - 0)^3 / (24N^2)) * 48 ≤ 1 × 10^(-9)

48 / (24N^2) ≤ 1 × 10^(-9)

N^2 ≥ 48 / (24 × 1 × 10^(-9))

N^2 ≥ 2 × 10^9

N ≥ √(2 × 10^9)

N ≥ 44721

Therefore, a value of N greater than or equal to 44721 satisfies the error bound of Error(SN) ≤ 1 × 10^(-9).

18% of the milk mixture and how much of the cream mixture should he use.

A dairyman wants to combine milk with 5 percent butterfat and cream with 75 percent butterfat to create a 56-liter combination. Butterfat should make up 53% of the final combination.

Let x represent the volume of MILK required for the combination, in liters.

Consequently, x/56 is the PROPORTION of milk in the mixture. [because the final mixture has 56 liters in total]

We require 56 - x liters of CREAM in the mixture because we have 56 liters overall in the mixture.

The PROPORTION of cream in the combination is therefore equal to (56 - x)/56.

Our goal is for the final mixture to have 75% butterfat.

Fill in the equation with each of these values to obtain:

50 = (x/60)(5) + ((60 - x)/60) (75)

Add 56 to both sides to get: 3000 = (5)(x) + (56 - x)(75)

The formula is:

Multiply both sides by 56 to get: 3000 = (5)(x) + (56 - x)(75)

Expand: 3000 = 5x + 4200 - 75x

Simplify: 3000 = 4200 - 70x

Subtract 4500 from both sides: -1300 = -70x

Solve: x = (-1300)/(-70) = (1300)/(70) = 130/7

If you don't want to divide 130 by 7, you can evaluate this quickly by first realizing that 30/7 = 18.

Consequently, 130/7 must be a little larger than 18.

The y-axis doesn't start at zero.

The intervals on the y-axis are too large.

Different bar widths are used on the same graph.

The y-axis starts at zero but has different intervals.

Answer:

The y-axis starts at zero and uses consistent intervals.

Step-by-step explanation:

The moment-generating function for y is given as eⁿᵇ - eⁿᵃ / n(b-a) and derivation of  moment-generating function of y is e-1/t

Given that,

The interval (0, 1) is covered by a uniform distribution of y, and a > 0 is a constant.

The moment generating function is eⁿᵇ - eⁿᵃ / n(b-a)

The given interval is (0,1)

Here a =0;

         b=1;

Now substitute the values of a and b in the above moment generating function we get,

y=eⁿᵇ - eⁿᵃ / n(b-a)

y=e^1-e^0/t(1-0)

y= e-1/t

Therefore, the derivation of the moment generating function is e-1/t

According to the given statement 16% is the probability that the person is age 48 or older.

A metric of a data set's deviation from the mean is referred to as "standard deviation" (or ""). While a high standard deviation indicates that the numbers are more spread, a smaller standard deviation suggests that the data are clustered around the mean.

After calculating the z-score, we will look up the value in the table on page (718–719).

We will employ the equation, to determine the z-score.

z= x−μ / σ

How is x=48

μ=41

σ=7 the z-score is,

z = 48 - 47 /7

z = 7 / 7

z = 1

The value for z=1 in the table is 0.84130, meaning that the region below the curve represents people who are 48 years of age and older. However, we are looking at the area that represents people who are 48 years of age and older, hence,

The 3 main features of a graph of the function gif g(x)

= f(x + 4) + 8 are: Translation (Shift) in x-axis: The entire graph of f(x) is shifted left or right by a distance of c units. If c is negative, the graph is shifted to the right; if c is positive, it is shifted to the left. Translation (Shift) in y-axis: The entire graph of f(x) is shifted upwards or downwards by a distance of k units. If k is positive, the graph is shifted upwards; if k is negative, it is shifted downwards. Affected Points: Every point on the graph of f(x) is shifted left or right by a distance of c units and up or down by a distance of k units to form the graph of the transformed function g(x).In this particular case, f(x) has been shifted 4 units to the left and then the entire graph has been shifted 8 units up.

Step-by-step explanation:

Yes, the inverse of the matrix which is \(A^{-1}\) = \(\begin{bmatrix} 0 & \frac{1}{3} \\ -\frac{1}{2} & 0 \end{bmatrix}\)  for the 2 x 2 matrix \(\begin{bmatrix} 6 & 3 \\ 3 & 0 \end{bmatrix}\).

To find the inverse of a matrix, we need to check if it is invertible first, which means its determinant should not be equal to zero.

Let's calculate the determinant of the matrix,

A: \(\begin{bmatrix} 6 & 3 \\ 3 & 0 \end{bmatrix}\)

det(A) = (6 x 0) - (3 x 3) = -9

Since the determinant is not equal to zero, we can conclude that matrix A is invertible.

To find the inverse of matrix A, we can use the following formula:

\(A^{-1}\) = (1/det(A)) x adj(A)

where adj(A) is the adjugate of A and can be calculated by taking the transpose of the matrix of cofactors of A.

The matrix of cofactors of A is:

\(\begin{bmatrix} 0 & -3 \\ -3 & 6 \end{bmatrix}\)

Taking the transpose of the matrix of cofactors, we get:

\(\begin{bmatrix} 0 & -3 \\ 3 & 6 \end{bmatrix}\)

So, the adjugate of A is:

adj(A) = \(\begin{bmatrix} 0 & -3 \\ 3 & 6 \end{bmatrix}\)

Now, we can find the inverse of A:

\(A^{-1}\) = (1/-9) x adj(A)

= (-1/9) x \(\begin{bmatrix} 0 & -3 \\ 3 & 6 \end{bmatrix}\)

= \(\begin{bmatrix} 0 & \frac{1}{3} \\ -\frac{1}{2} & 0 \end{bmatrix}\)

Therefore, the inverse of matrix A is:

\(A^{-1}\) = \(\begin{bmatrix} 0 & \frac{1}{3} \\ -\frac{1}{2} & 0 \end{bmatrix}\)
