Step-by-step explanation:

The value of given expressions is -4\(x^{-2}\) + 3\(y^{0}\) = 19 and 2\(x^{0}\)\(y^{-2}\) = 0.08

Simplifying an equation is simply another way of saying solving a math problem. When you simplify a phrase, you are attempting to write it in the simplest way feasible. In conclusion, there should be no more adding, subtracting, multiplying, or dividing to do.

Given expression 1. -4\(x^{-2}\) + 3\(y^{0}\)  2. 2\(x^{0}\)\(y^{-2}\)

Expression for x =2 and y=5

-4x-2 + 3y0

= -4(2)-2 + 3(5)0

= 16+3

=19

Now

2x0y-2

= 2(2)0x(5)-2

= 2 x (1/25)

= 2 x 0.04

= 0.08

Therefore the value of given expressions is -4\(x^{-2}\) + 3\(y^{0}\) = 19 and 2\(x^{0}\)\(y^{-2}\) = 0.08

By analyzing the graph and evaluating the objective function at each vertex of the feasible region, we can find the optimal solution, which is the vertex that maximizes the objective function z = 3x + y.

To find the optimal solution of the given problem using the graphical method, we need to plot the feasible region determined by the given constraints and then identify the point within that region that maximizes the objective function.

Let's start by graphing the constraints:

1. Plot the line 2x - y = 5. To do this, find two points on the line by setting x = 0 and solving for y, and setting y = 0 and solving for x. Connect the two points to draw the line.

2. Plot the line -x + 3y = 6 using a similar process.

3. The x-axis and y-axis represent the constraints x ≥ 0 and y ≥ 0, respectively.

Next, identify the feasible region, which is the region where all the constraints are satisfied. This region will be the intersection of the shaded regions determined by each constraint.

Finally, we need to identify the point within the feasible region that maximizes the objective function z = 3x + y. The optimal solution will be the vertex of the feasible region that gives the highest value for the objective function. This can be determined by evaluating the objective function at each vertex and comparing the values.

Note: Without a specific graph or additional information, it is not possible to provide the precise coordinates of the optimal solution in this case.

Answer: x = 10

Step-by-step explanation:

4x+89=129

(2 parallel straight lines have congruent angles)

then solve for x.

Step 1: Subtract 89 from both sides of the equation.

4x = 40

(We want to isolate the variable x on one side of the equation. To do this, we need to get rid of the number 89 that is currently on the right side of the equation. To do this, we subtract 89 from both sides of the equation.)

Step 2: Divide both sides of the equation by 4.

x = 10

(To isolate the variable x further, we need to get rid of the coefficient 4 that is currently in front of x. To do this, we divide both sides of the equation by 4.)

Answer:

The Confidence Interval = (2180, 2782)

Lower Bound for the true average difference between 1-minute modulus and 4-week modulus = 2180

Upper Bound for the true average difference between 1-minute modulus and 4-week modulus = 2782

- The interval obtained represents the range of values that the true average difference between 1-minute modulus and 4-week modulus can take on.

Step-by-step explanation:

The confidence interval for any distribution is the range of values that the true population mean can take on with some level of confidence.

It is given mathematically as

Confidence Interval = (Sample Mean) ± (Margin of Error)

The Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as

Margin of Error = (Critical Value) × (Standard Error of the Mean)

Before anything, we first state the conditions necessary for the confidence interval calculated to be valid.

- The sample must be a random sample extracted from the population distribution using random sampling technique.

- The sample distribution must be normal or approximately normal and this is confirmed by knowing that the population distribution is normal or almost normal.

These two conditions are assumed to be plausible for this sample distribution.

Here, we need the confidence interval for the true average difference between 1-minute modulus and 4-week modulus.

So, before anything, we need to first fin the sample mean and standard deviation for the differences obtained from the sample specimens.

904, 3370, 2580, 3117, 2850, 2690, 2180, 1241, 2210, 2350, 2260, 2758, 2880, 2750, 3520, 2033

Mean = (Σx/N)

Σx = Sum of all the variables = 39693

N = Sample size = 16

Sample Mean = (39693/16) = 2480.8125

Standard deviation = \(\sqrt{\frac{Σ(x - xbar)^{2}}{N-1}\\}\)

x = each variable

xbar = sample mean = 2480.8125

Note that we use (N-1) for the standard deviation because it is a sample standard deviation.

\(\sqrt{\frac{Σ(x - xbar)^{2}}{N-1}\\}\) = √(7227548.4375/15) = √(481836.5625)

= 694.14448243863 = 694.1445

Confidence Interval = (Sample Mean) ± (Margin of Error)

Margin of Error = (Critical Value) × (Standard Error of the Mean)

Confidence Interval = (Sample Mean) ± [(Critical Value) × (Standard Error of the Mean)]

Critical Value is obtained from the t-distribution table since no information on the population standard deviation is known.

For that, we need the significance level for the test and the degree of freedom.

Significance level = α = 0.05 (given in the question)

Degree of freedom = N - 1 = 16 - 1 = 15

t(0.05, 15) = 1.753 (from the t-distribution tables)

Standard error of the Mean = σₓ = (σ/\(\sqrt{N}\)) = (694.1445/\(\sqrt{16}\)) = 173.536125 = 173.536

Confidence Interval = (Sample Mean) ± [(Critical Value) × (Standard Error of the Mean)]

CI = (2480.8125) ± [(1.753 × 173.536)]

CI = (2480.8125) ± (301.09385)

CI = (2179.71865, 2781.90635)

CI = (2180, 2782)

This interval represents the range of values that the true average difference between 1-minute modulus and 4-week modulus can take on.

Step-by-step explanation:

If he always  works 8 hours per day then he can take 3.75  days off.

Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed.

We denote division by '÷' this symbol.

Given that,

He has  only have 30 hours of vacation time left,

Working time = 8 hours/day

Days off = ?

If he has 30 hours of vacation time left and you work 8 hours per day, you can take the following number of days off:

= 30 hours/8 hours per day

= 3.75 days

So, you can take 3.75 days off, which is equivalent to 3 full days and 12 hours.

The image of  y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:

The graph will be a vertical parabola opening downwards

when the function y = −2x^2 − 20x + 2 translates right 4 units it gives  

y = -2(x - 4)^2 − 20(x - 4) + 2

going up two units

y = -2(x - 4)^2 − 20(x - 4) + 2 + 2

simplifying the equation further gives

y = -2(x - 4)(x - 4) − 20(x - 4) + 4

y = -2(x^2 - 8x + 16) - 20x - 80 + 4

y = -2x^2 + 16x - 20x - 32 - 80 + 4

y = -2x^2 - 4x - 108

completing the square

-2x^2 - 4x - 108 = 0

-2x^2 - 4x = 108

-2x^2 - 4x + (4/4)^2 = 108 -(4/4)^2

The dimensions of the rectangular field are given as follows:

The perimeter of a rectangle is given by twice the sum of the length and the width of the rectangle, as follows:

P = 2(l + w).

For this problem, the perimeter is of 582 yards, hence:

2(l + w) = 582

l + w = 291.

The length of the field is 4 yards less than quadruple the width, hence:

l = 4w - 4.

Then the width is obtained as follows:

4w - 4 + w = 295

5w = 295

w = 295/5

w = 59.

Answer:

8m ×3.5m

Step-by-step explanation:

Area of rectangle= length ×width

Let the length and width of the rectangle be L and W meters respectively.

Area of rectangle= LW

LW= 28 -----(1)

L= 2W +1 -----(2)

Subst. (2) into (1):

(2W +1)(W)= 28

Expand:

2W² +W= 28

-28 on both sides:

2W² +W -28= 0

Factorise:

(W +4)(2W -7)= 0

W +4=0 or 2W -7=0

W= -4 (reject) or W= 3.5

Substitute W= 3.5 into (2):

L= 2(3.5) +1

L= 7 +1

L= 8

∴ The dimensions of the rectangle is 8m ×3.5m.

What are similar triangles?

To be similar, two triangles must have the same shape, which means that their corresponding angles are equal. If the angles in two triangles are the same, they are said to be "congruent". If the angles are congruent and the sides are proportional, then the triangles are similar.

Let's call the height of the building "h". We can use similar triangles to find the height of the building.

This forms two triangles, one with the height of the building and the other with the length of the shadow.

Using the properties of similar triangles, we can set up the following proportion:

h/10 = (h+x)/26

where x is the distance from the tip of the shadow to the bottom of the building. We want to solve for h, so we can simplify and solve for h:

26h = 10 (h+x)

26h = 10h + 10x

16h = 10x

h = 10x/16

h = 0.625x

So, the height of the building is 0.625 times the distance from the tip of the shadow to the bottom of the building. We know that the distance from the top of the building to the tip of the shadow is 26 m, so the distance from the tip of the shadow to the bottom of the building is:

x = 26 - h = 26 - 0.625x

Solving for x, we get:

1.625x = 26

x = 16

Therefore, the height of the building is:

h = 0.625x = 0.625(16) = 10

So, the height of the building is 10 meters.
