The measurement deviates from the mean by more than 100 standard deviations.

It's a way to gauge how widely apart each data point is from the mean. The standard deviation formula comes in two different forms: Standard deviation for the population When you can measure the entire population or the entire collection of data, you use the population version of the formula. Experts in statistics have determined that measurements that fall within a 2 SD range of the true value are more accurate than those that do not..

The coordinates of the point X are (1 + 2, 6 - 1.25) = (3,4.75).

The segments, PX and XQ, have lengths in a ratio of 1: 2.

A line segment is partitioned when it is divided into equal parts according to a specified ratio. The total number of partitions of the line segment must be equal to the sum of the two values in the ratio.

Suppose you have a line segment PQ on the coordinate plane, and you need to estimate the point on the segment 1/3 of the way from P to Q.

Where P exists at the origin and line segment is a horizontal one.

The length of the line exists 6 units and the point on the segment 1/3 of the way from P to Q would be 2 units away from P, 4 units away from Q and would be at (2, 0).

The segment exists not a horizontal or vertical line:

The components of the directed segment PQ exists (6, 3) and we require to estimate the point, say X on the segment 1/3 of the way from P to Q. Then, the components of the segment PX exists [tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(3)\right\rangle=\langle 2,1\rangle$[/tex].

Since the initial point of the segment exists at origin, the coordinates of the point X exists given by (0+2, 0+1) = (2, 1).

where neither P nor Q exists at the origin.

Use the end points of the segment PQ to estimate the components of the directed segment.

[tex]$\left\langle\left(x_2-x_1\right),\left(y_2-y_1\right)\right\rangle=\langle(7-1),(2-6)\rangle \\[/tex]

= (6, -4)

The components of the segment PX where X exists a point on the segment 1/3 of the way from P to Q are

[tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(-4)\right\rangle[/tex]= (2, -1.25)

To estimate the coordinates of the point X add the components of the segment PX to the coordinates of the initial point P.

Therefore, the coordinates of the point X exists (1 + 2, 6 - 1.25) = (3,4.75).

The segments, PX and XQ, have lengths in a ratio of 1: 2.

Using the probability concept, it is found that:

a) The tree diagram is given by the image at the end of the answer.

b) The probability is of 0.18 = 18%.

c) The probability is of 0.72 = 72%.

A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.

For item a in this problem, we have two independent events, hence the tree diagram will contain two nodes, one with each event and it's probabilities.

For item b, since the events are independent, to find the probability of both, we multiply the probability of each, hence:

0.3 x 0.6 = 0.18.

For item c, first we find the probability of none being completed, hence:

(1 - 0.3) x (1 - 0.6) = 0.7 x 0.4 = 0.28.

At least one is complementary to none, hence the probability is given as follows:

p = 1 - 0.28 = 0.72 = 72%.

Answer

Step 1:         6,3

Step 2:       x1  -1                     y2- 2

Step 3:           1, 7

Step-by-step explanation:

The y intercept of the function f(x) = 2^2−4 is 0

The x intercept of the function f(x) = 2^2−4 is 0 or 2

The zeros of the function f(x) = 2^2−4 is 0 or 2

When f(x) = f(-4) then the function f(-4) = 48

When f(x) = 2 then x = -0.4142 or 2.142

given data

f(x) = 2^2 − 4

The y intercept

f(x) = 2^2−4

y = 2^2−4

at x = 0

y = 2 ( 0 ) ^2 - 4 ( 0 )

y = 0 - 0

y = 0

The x intercept

f(x) = 2^2 − 4

y = 2^2− 4

at y = 0

0 = 2^2− 4

0 = 2x( x - 2 )

2x = 0    OR     x - 2 = 0

x = 0      OR     x = 2

The zeros

This same as the x intercept

f(-4)

f(x) = 2^2− 4

f(-4) = 2 (-4)^2 - 4 * -4

f(-4) = 2 * 16 + 16

f(-4) = 48

f(x) = 2 when x =

f(x) = 2^2− 4

2 = 2x( x - 2 )

1 = x^2 - 2x

The solution set for the inequality is p > -9.4. See attachment below for the graph.

An open circle is used when the inequality sign involved is ">" or "<". That is, it is used for numbers that are less than or greater than.

An arrow shaded to the right means the solution set is greater than a given value, while an arrow shaded to the left means the solution set includes all values that are less than a given value.

Given the inequality, p + 3.6 > −5.8, solve for p:

p + 3.6 > −5.8

Subtract 3.6 from both sides

p + 3.6 - 3.6 > -5.8 - 3.6

p > -9.4

Thus, the solution set would be all the values that are greater than -9.4. The graph is shown below.

A translation can be defined as a type of transformation which moves every point of the object in the same direction, as well as for the same distance.

Since the pre-image of polygon ABCD is translated (shifted) vertically downward by 4 units and right 5 units, the coordinates of the image of polygon A'B'C'D' would be given by:

The mathematical statement of the expression t - 3 is the difference between t and 3

Expressions are mathematical statements that are represented by variables, coefficients and operators

The algebraic expression is given as

t - 3

The above mathematical representation is an algebraic expression that is already in its most simplified form

This means that the algebraic expression cannot be further simplified

However, the algebraic expression can be rewritten as a mathematical statement

Recall that, we have

t - 3

The pronunciation of the above expression is:

t minus 3

In expressions, minus represents difference

So, we have

t minus 3 can be represented as the difference between t and 3

Using vertical angles, Maggie made her mistake when combining the like terms of x, which has a result of -3x and not 3x, hence the correct result is of x = 9.

Vertical angles are two angles that are opposite by the same vertex when two lines cross each other, and they are congruent, that is, they have the same measure.

For this problem, the vertical angles are given as follows:

Since they are congruent, we can solve for the variable x as follows:

4x + 2 = 7x - 25.

Moving all the terms with x to the left side of the equality and all the constant terms to the right side, with opposite signal, we have that:

4x - 7x = -25 - 2

Combining the like terms, it is found that:

-3x = -27.

Here happened Maggie's mistake, as 4x - 7x = -3x, hence the correct solution is given by:

3x = 27

The dimensions of the region which enclose the maximum area is a side of 162 feet and vertical segment of 108 feet

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the side parallel to the vertical segment and y represent the other side. If the farmer has 648 feet of fencing, hence:

x + x + y + y + x = 648

3x + 2y = 648

y = 324 - 1.5x

Area (A) = xy

A = xy

A = x(324 - 1.5x)

A = 324x - 1.5x²

The maximum area is at A' = 0, hence:

A' = 324 - 3x

324 - 3x = 0

3x = 324

[tex]a_{n}[/tex] =  [tex]a_{1}[/tex] + (n−1)d

where [tex]a_{1}[/tex] is the first term, [tex]a_{n}[/tex] is the nth term and d is the difference between a term and its previous term.

With the help of provided arithmetic sequence we can write;

[tex]a_{n}[/tex] = -385

[tex]a_{1}[/tex] = 7

d = difference between a term and its previous term = 3 - 7 = -4

Put these values in equation 1 , we will get

The fraction of straight section of motor racing circuit is 3/14 miles.

To find the fraction of circuit which is straight, we will perform division. The fraction will be found as - Fraction = length of straight section ÷ total length of motor racing circuit

Keep the values in mentioned relation to find the fraction of circuit which is straight.

Converting the mentioned lengths from mixed fraction to fraction.

Length of motor racing circuit = (6×5 + 5)/6

Length of motor racing circuit = 35/6

Length of straight section of circuit = (4×1 + 1)/4

Length of straight section of circuit = 5/4

Fraction of straight circuit = (5/4)/(35/6)

Simplifying the fraction

Fraction of straight circuit = (5×6)/(35×4)

Performing multiplication in numerator and denominator

Fraction of straight circuit = 30/140

Performing division

Fraction of straight circuit = 3/14 miles
