Find the total of the areas under the standard normal curve to the left of z1=−2.575 and to the right of z2=2.575. Round your answer to four decimal places, if necessary.

Answer:

The following equations are equivalent:

2 + x = 5

x + (negative 4) = 7

Negative 5 + x = negative 2

All of these three equations are equivalent because they all represent the same mathematical relationship between x and other numbers. The variable x is the same in each equation. We can see this by applying the same operation on both sides of the equations, and the variable x will cancel out and the two sides will be equal.

A "full table of 5" refers to a multiplication table that includes all of the products of the number 5 multiplied by the integers from 1 to some maximum value.

Here is an example of a full table of 5:

5 x 1 = 5

5 x 2 = 10

5 x 3 = 15

5 x 4 = 20

5 x 5 = 25

5 x 6 = 30

5 x 7 = 35

5 x 8 = 40

5 x 9 = 45

5 x 10 = 50

In this example, the maximum value for the multiplier is 10, but a full table of 5 can continue with any number of rows. This table is useful for memorizing the multiplication facts of 5, and also to see the pattern of the multiples of 5.

It's worth to mention that if you are looking for a way to calculate the products you could use a loop or a function that takes the maximum value of the multipliers as an input and prints the full table of 5.

The value of 0.55 hectometers expressed in decimeters is 550 decimeters. The result is obtained by using the concept of unit ladder system.

The common length units are kilometers to milimeter. The conversion can be described in a unit ladder system as follows.

km (kilometers)

  hm (hectometers)

     dam (decameters)

        m (meters)

           dm (decimeters)

              cm (centimeters)

                  mm (millimeters)

Every time the length unit goes down, it is multiplied by ten. Every time the length unit goes up, it is divided by ten.

We have 0.55 hectometers. Express that value in decimeters!

From hectometers to decimeters, it goes down 3 times. So,

0.55 hectometers = 0.55 × 10 × 10 × 10 decimeters

0.55 hectometers = 0.55 × 1000 decimeters

0.55 hectometers = 550 decimeters

Hence, 0.55 hectometers is equal to 550 decimeters.

Using a graphing calculator, we have the following summary

The regression equation is represented as

Regression Equation = ŷ = bX + a

Where

b = SP/SSX = 386.5/17.5 = 22.08571

Mary is mistaken in her conclusion that the two triangles are not similar because size does not determine similarity. Similarity is determined by the proportionality of corresponding sides and the congruence of corresponding angles. Congruence is the equality of all the measures of the corresponding parts of two figures.

In order to determine if two triangles are similar, we must compare the ratios of corresponding sides. If the ratios of corresponding sides are equal, then the triangles are similar. In the diagram, it is not specified what the measures of the sides of the triangles are, so it is not possible to determine if the triangles are similar based on the information given. However, if the ratio of corresponding sides are same, then the triangles are similar.

It is important to note that similarity and congruence are different concepts. Congruence refers to the equality of all measures of corresponding parts of two figures, including side lengths and angles. Similarity refers to the proportionality of corresponding parts, including side lengths and angles. A triangle can be similar to another triangle without being congruent, and congruent triangles are always similar.

In summary, Mary is mistaken because the size of the triangle does not determine similarity, it is determined by the proportionality of corresponding sides and congruence of corresponding angles. Without knowing the measures of the sides of the triangles, it is impossible to determine if the triangles are similar based on the information given.

Proportionality is a fundamental concept in mathematics and physics. It is a relationship between two or more variables where a change in one causes a proportional change in the other. In other words, the ratio between the two remains constant. Proportionality is an important concept in mathematics because it is used to make predictions and solve problems.

To find the slope of the line representing the number of goats the farmer has over time, we need to use the formula:

Where y2 and y1 are the number of goats the farmer has at the end of two different months, and x2 and x1 are the number of months that have passed since he started selling the goats.

In this case:

So the slope of the line is:

The slope of the line is -14, which means that the number of goats the farmer has decreases by 14 goats per month.

It's important to note that when the value of the slope is negative, it means that the line is going down; this means that the farmer is selling goats at a constant rate.

a)   Length of the parking lot: 98 m

b)   Width of the pool: 89 m

Step-by-step explanation:

a)   The formula for the area of a rectangle is [tex]A=lw[/tex].

We need to evaluate the length. Lets solve for [tex]l.[/tex]

[tex]A=lw[/tex]

Divide both sides of the equation by [tex]w[/tex].

[tex]\frac{A}{w} =l[/tex]

We are given

[tex]A=8428\\w=86[/tex]

Lets evaluate [tex]l[/tex].

[tex]\frac{8428}{86}=l[/tex]

[tex]l=98[/tex]

b)   The formula for the perimeter of a rectangle is [tex]P=2l+2w[/tex].

We need to evaluate the width. Lets solve for [tex]w[/tex].

[tex]P=2l+2w[/tex]

Subtract [tex]2l[/tex] from both sides of the equation.

[tex]P-2l=2w[/tex]

Divide each term by 2.

[tex]\frac{P}{2} -\frac{2l}{2} =\frac{2w}{2}[/tex]

Simplify.

[tex]w=\frac{P}{2}-l[/tex]

We are given

[tex]P=376\\l=99[/tex]

Lets evaluate [tex]w[/tex].

[tex]w=\frac{376}{2}-99[/tex]

[tex]w=188-99[/tex]

[tex]w=89[/tex]

Answer:

a) 98m , b) 89m

Step-by-step explanation:

(a) Given,

To Find : Length of the Parking lot

Length of a rectangle shape can be derived by the formula,

[tex]l = \frac{A}{w}[/tex]

[tex]l = \frac{8428}{86}[/tex]

[tex]l = 98m[/tex]

Hence , the length of a rectangular parking lot is 98m

(b) Given ,

To Find : The width of the rectangular pool

We take the width as variable 'x'

Now we plug it into the perimeter of a rectangle equation

[tex]376 = 2(99 + x)[/tex]

Using distributive property we,

[tex]376 = 198 + 2x[/tex]

We now flip the equation

[tex]2x + 198 = 376[/tex]

[tex]2x = 376 - 198[/tex] ( Transposing into the right hand side)

[tex]2x = 178[/tex]

[tex]x = \frac{178}{2}[/tex]

The quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

A quadratic equation in standard form is of the form ax² + bx + c, where a, b, and c are constants.

The axis of symmetry of a quadratic equation is given by the line x = -b/2a, so if the axis of symmetry is x=-2, we can set -b/2a = -2, which gives b = 4a.

To find the y-intercept of the quadratic equation, we can set x = 0 and substitute that into the equation: y = a(0)² + b(0) + c = c
So, if the y-intercept is (0,6) then c = 6.

By using above two information, we can write the quadratic equation in standard form as:

a(x+2)² + 4a(x+2) + 6 =0
=> a(x²+4x+4) + 6 = 0
=> a(x²+4x+4) = -6
=> a(x²+4x+4) = -6
=> x² + 4x + 4 = -6/a
=> x² + 4x + 4 = -6/a +10
=> x² + 4x - 6 = 0

So, the quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

Answer: y = 8x

Step-by-step explanation:

The line passes through points (1,8) and (2,16).

Using this, we can first find the slope.

Slope = Δy/Δx = 8/1 = 8

So the slope is 8.

The equation is now

y = 8x + b

Let's use the point (1,8) to find the value of b now.

8 = 8 +b

b = 0

Therefore, y = 8x is the answer.

From inspection of the given graph, two points on the line are:

Substitute the points into the slope formula to find the slope of the line:

[tex]\implies m=\dfrac{16-0}{2-0}=\dfrac{16}{2}=8[/tex]

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

The y-intercept is the y-value of the point where the line crosses the y-axis. From inspection of the given graph, the y-intercept is zero. So b=0.

Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:
