The data points from the set of collected that are outside the [-2, 2] range means that the data is an outlier or unusual data

The z–score also known as standard score is the number of standard deviation a score is differs from the mean or average score

The z–score is given by the formula;

[tex]Z = \frac{x - \mu}{ \sigma} [/tex]

The Z–Score is therefore, the number of standard deviations, a data point, x is far from the mean, [tex] \mu [/tex]

The standard deviation, [tex] \sigma [/tex], is given by the formula;

[tex] \sigma = \sqrt{ \frac{ \sum {( x_{i} - \mu)}^{2} }{N} } [/tex]

As the value of [tex] \sigma [/tex] increases, the variability increases, and the Z–Score decreases, such that a Z–Score of less than -2 or greater than 2 are unusual.

From the z–score calculator, the probability that a data point has a z–score of less than -2 or more than 2 is 0.02275

Such a data point can be taken as an outlier

Therefore, data that is outside the [-2, 2] range is an unusual (outlier) data

Step-by-step explanation:

13+6.2+5.8

= 13+(6.2+5.8)

- the sum in the parentheses is easy to calculate (it = 12).

The new cost of the shirt is $135

Macy's offer a shirt at the cost of $300

One week later, they offer 25% off

25/100 × 300

0.25 × 300

= 75

300-75

= 225

The next week it was reduced by an additional 40% off

40/100 × 225

= 0.4 × 225

= 90

225-90

= 135

Hence Macy's new shirt costs $135

The geometric sequence has an explicit equation of f(n) = 3^(n - 1)

The given parameters are

r = 3

f(1) = 1

The above means that we have the following parameters:

The explicit equation of the geometric sequence is represented as

f(n) = f(1) * r^(n - 1)

Substitute the known values in the above equation

So, we have the following equation

f(n) = 1 * 3^(n - 1)

Evaluate the products

So, we have the following equation

f(n) = 3^(n - 1)

The equation of line in slope-intercept form is found as y = -3x + 7.

For the given question;

The two passing point of the line are;

(x1, y1) = (2,1)

(x2, y2) = (1,4)

Slope = m = (y2 - y1)/(x2 - x1)

Put the values.

m = (4 - 1)/(1 - 2)

m = -3

Then, the equation of the line in slope intercept form is found using two point equation.

y - y1 = m(x - x1)

y - 1 = -3(x - 2)

Simplifying,

y = -3x + 7

-3 is the slope and 7 is the y intercept.

Thus, the equation of line in slope-intercept form is found as y = -3x + 7.

The given equation is 1-degree linear equation in one variable.

What is linear equation?

A linear equation is one that may be written as a1x1+a2x2+......+anxn in mathematics, where a1, a2,...., an are the coefficients, which are frequently real integers. The coefficients, which may be any expressions as long as they don't contain any of the variables, can be thought of as the equation's parameters. The coefficients a1 to a must not all be 0 in order for the equation to have any sense. An alternative method for creating a linear equation is to equalize a linear polynomial over a field, from which the coefficients are drawn, to zero. The numbers that, when used to replace the unknowns in such an equation, result in the equality, are the solutions.

x+1 = x+1 is a 1-degree linear equation in one variable (x).

The equation of the function is given as:

n(x) = -1 -1/3x + 1 2/3

The replacement set is given as

x = -2, 0, 5

So, we replace the variables using the elements in the replacement set

When x = -2, we have

n(-2) = -1 -1/3 x -2 + 1 2/3

Evaluate the equation

So, we have the following equation

n(-2) = 4/3

When x = 0, we have

n(0) = -1 -1/3 x 0 + 1 2/3

Evaluate the equation

So, we have the following equation

n(0) = 2/3

When x = 5, we have

n(5) = -1 -1/3 x 5 + 1 2/3

Answer:

a = 22, b = 6, c = 14, d = 8

Step-by-step explanation:

sum the elements in the leading diagonal , that is

7 + 15 + 23 = 45

then all other rows and columns and the other diagonal total 45

top row

7 + a + 16 = 45

23 + a = 45 ( subtract 23 from both sides )

a = 22

middle row

24 + 15 + b = 45

39 + b = 45 ( subtract 39 from both sides )

b = 6

left column

7 + 24 + c = 45

31 + c = 45 ( subtract 31 from both sides )

c = 14

bottom row

c + d + 23 = 45 , that is

14 + d + 23 = 45

37 + d = 45 ( subtract 37 from both sides )

Considering the definition of an equation and the way to solve it, the girls will both pay the same if they buy six pairs of pants and one sweater.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values appear.

The solution of a equation means determining the value that satisfies it. In this way, by changing the unknown to the solution, the equality must be true.

To solve an equation, keep in mind:

Being "x" the number of pairs of pants, you know that:

The equation in this case is:

17.95x + 24 = 18.95x + 18

Solving:

24 -18= 18.95x - 17-95x

6= x

Part 1: The first five terms of the sequence are -1, 16, 69, 266, 1039

Part 2: The first five terms of the sequence are 12, 12, 130/9, 69/4, 126

Part 1:

For finding the first five terms we will substitute values in n from 1,2,3,4 and 5

an = 2n^2 + 5n-10

a1 = 2(1)^2 + 5(1)-10

=4+5-10 = -1

So, the first term is -1

a2 = 2(2)^2+5(2)-10

= 16+10-10 =16

The second term is 16

a3 = 2(3)^2+5(3)-10

=64+15-10

=69

The third term is 69

a4 = 2(4)^2+5(4)-10

=256+20-10

=266

The fourth term is 266

a5 = 2(5)^2+5(5)-10

= 1024+25-10

= 1039

The fifth term is 1039

Part 2:

an = 3n+4/n^2+5

a1 = 3(1)+4/1^2+5

= 3+4+5

= 12

The first term is 12

a2 = 3(2)+4/2^2+5

= 6+1+5

= 12

The second term is 12

a3 = 3(3)+4/3^2+5

= 9+4/9+5

= 81+4+45/9

=130/9

The third term is 130/9

a4 = 3(4)+4/4^2+5

= 12+4/16+5

=17+1/4

=69/4

The fourth term is 69/4

a5 = 3(5)+4/5^2+5

= 15+4/25+5

=20+4/25

[tex]\textsf{Draw the line } \;\;y=0\;\;\textsf{and shade above (to the right of) the line}.[/tex]

Therefore, the feasible region is bounded by the corner points:

Determine the value of z at the corner points by substituting the x and y values of the points into the equation for z:

[tex]\textsf{Value of $z$ at $A(0,0)$}: \quad 6(0)+12(0)=0[/tex]

[tex]\textsf{Value of $z$ at $B(0,4)$}: \quad 6(0)+12(4)=48[/tex]

Hence, the maximum value of z is 48 at B(0, 4).
