distance = sqrt√(  (x2 - x1)^ + (y2 - y1)^2  )

x1 = 6

x2 = 8

y1 = -8

y2 = -3

distance = sqrt(  ( 8 - 6)^2 + (-3 - -8)^2  )

distance = sqrt( 2^2 + 5^2)

The mean weight of 32 students is 98.3 lb. The total weight of 32 students would be 3145.6 lb.

To find the total weight of 32 students, we need to multiply the mean weight of each student by the number of students. In this case, the mean weight of each student is 98.3 lb.

So, to find the total weight, we can use the formula:

Total weight = Mean weight × Number of students

Total weight = 98.3 lb × 32

Total weight = 3145.6 lb

Therefore, the total weight of 32 students would be 3145.6 lb.

It's important to note that the mean weight is the average weight of the 32 students. It is calculated by adding up the weight of each student and then dividing by the total number of students. So, if the weights of the students are evenly distributed, then the mean weight is a good estimate of the total weight. However, if the weights are not evenly distributed, then the total weight may be slightly different.

Overall, it's important to use statistical measures such as mean, median, and mode to gain insights into data and make informed decisions.

the line segment after a 90 counterclockwise rotation about the origin is attached accordingly.

A rotation is a sort of transformation  that rotates each point in a figure a specific number of degrees around a particular  point.

To do a 90-  degree counterclockwise rotation about  the origin, we can use the following rotation  formula

x ' = x *  cos( θ) - y * sin(θ)

 y' =  x * sin(θ )+ y * cos( θ)

where   (x, y) are the original coordinates and (x ', y') are the coordinates after the rotation.

Applying this

For   point A (- 5, -3) we have

x' = (-5) * cos(90°) - ( -3) * sin(90 °) = 3

y' = (-5) * sin(90°)+ (-3) * cos(90°) =  -5

So the new coordinates after the 90-degree counterclockwise rotation about the origin for point A are (3, -5).

 point B (1  , -2)

x' =  (1 ) * cos(90°) - (-2) * sin(90°) = 2

y ' = (1 ) * sin ( 90°) + ( - 2) * cos (90 °) = 1

So the new coordinates after the 90-degree counterclockwise rotation about the origin   for point B are (2, 1).

The line segment after a 90-degree counterclockwise rotation about the origin would connect point A' (3, -5) to point B' (2, 1).

The actual area of the park is 593142 m²

The space enclosed by the boundary of a plane figure is called its area. Area is measured in squared units.

The scale of the drawing of the park is 1cm represent 110m. This means that 1cm on the drawing is 110m actual length.

Therefore , since the length on the drawing is 8.6 cm, the actual length of the park = 8.6 × 110 = 946m.

The width on the drawing is 5.7 cm , therefore the actual width of the park = 110 × 5.7 = 627m

Therefore, the park takes the shape of a rectangle, The area of the park is therefore calculated as:

A = l× w

It is important to consider the scale of measurement and the specific characteristics of the variables when selecting an appropriate statistical test.The tests can be classified as follows:

1. A researcher measures the proportion of schizophrenic patients born in each season.

This test is nonparametric. The scale of measurement is categorical, as the seasons (spring, summer, fall, winter) represent distinct categories rather than continuous numerical values. Therefore, parametric assumptions, such as normality and equal variances, do not apply to this measurement.

2. A researcher measures the average age that schizophrenia is diagnosed among male and female patients.

This test is parametric. The scale of measurement is continuous and numerical (age in years). Parametric tests, such as t-tests or ANOVA, can be applied when working with continuous data, assuming the data meet the required assumptions (e.g., normality, independence, and equal variances).

3. A researcher tests whether frequency of Internet use and social interaction are independent.

This test can be both parametric or nonparametric, depending on the measurement scale and the specific statistical test used. If the variables are measured on a nominal or ordinal scale, nonparametric tests, such as the chi-square test, would be appropriate. If the variables are measured on a continuous scale, parametric tests, such as logistic regression, could be employed.

4. A researcher measures the amount of time (in seconds) that a group of teenagers uses the Internet for school-related and non-school-related purposes.

This test is parametric. The scale of measurement is continuous (time in seconds), and parametric tests, such as t-tests or ANOVA, can be utilized to compare means or variances, assuming the required assumptions are met.

Answer: 8

Step-by-step explanation:

= (-100) ÷ (200 - 30 x 5) + 10

= (-100) ÷ (200 - 150) +10

= (-100) ÷ 50 + 10

= -2 + 10

=8

Answer:   8

Step-by-step explanation:    Remember BIDMAS, order of operations (brackets, indices, division, multiplication, addition, subtraction), since we have multiple brackets inside one another we'll start with the most inner brackets and then work from there.

14-(-16) = 30

30 x 5 = 150

200 - 150 = 50

(-100) ÷ 50 = -2

-2 + 10 = 8

y = 2 ( x + 3/4 )^2 − 25 8

Answer:

\(\boxed{ \ 2(x+\dfrac{3}{4})^2-\dfrac{25}{8}\ }\)

Step-by-step explanation:

we should write this function

\(2x^2+3x-2\)

this way \(a(x-b)^2+c\)

let s check the first terms in\(x^2\) and x

\(2x^2+3x\)

this is the beginning of

    \(2(x+\dfrac{3}{4})^2\)

indeed

   \(2(x+\dfrac{3}{4})^2=2x^2+3x+2(\dfrac{3}{4})^2=2x^2+3x+\dfrac{9}{8}\)

so we can write that

   \(2x^2+3x=2(x+\dfrac{3}{4})^2-\dfrac{9}{8}\)

then

   \(2x^2+3x-2=2(x+\dfrac{3}{4})^2-\dfrac{9}{8}-2=2(x+\dfrac{3}{4})^2-\dfrac{9+16}{8}=2(x+\dfrac{3}{4})^2-\dfrac{25}{8}\)

Step-by-step explanation:

The solution to the given differential equation is \(y = a_0x^{[0]} + a_1x^{[1]} + a_2x^{[2]}\), where a_0, a_1, and a_2 are constants.

To fathom the given differential equation, xy'' + y' = 0, we will begin by expecting a control arrangement of the frame y = ∑(n=0 to ∞) a_nx^n, where a_n speaks to the coefficients to be decided.

Separating y with regard to x, we get:

\(y' = ∑(n=0 to ∞) a_n(nx^[(n-1))] = ∑(n=0 to ∞) na_nx^[(n-1)]\)

Separating y' with regard to x, we get:

\(y'' = ∑(n=0 to ∞) n(n-1)a_nx^[(n-2)]\)

Presently, we substitute these expressions for y and its subsidiaries into the differential condition:

\(x(∑(n=0 to ∞) n(n-1)a_nx^[(n-2))] + (∑(n=0 to ∞) na_nx^[(n-1))] =\)

After improving terms, we have:

\(∑(n=0 to ∞) n(n-1)a_nx^[(n-1)] + ∑(n=0 to ∞) na_nx^[n] =\)

Another, we compare the coefficients of like powers of x to zero, coming about in a boundless arrangement of conditions:

For n = 0: + a_0 = (condition 1)

For n = 1: + a_1 = (condition 2)

For n ≥ 2: n(n-1)a_n + na_n = (condition 3)

Disentangling condition 3, we have:

\(n^[2a]_n - n(a_n) =\)

n(n-1)a_n - na_n =

n(n-1 - 1)a_n =

(n(n-2)a_n) =

From equation 1, a_0 = 0, and from equation 2, a_1 = 0.

For n ≥ 2, we have two conceivable outcomes:

n(n-2) = 0, which gives n = or n = 2.

a_n = (minor arrangement)

So, the solution to the given differential equation is \(y = a_0x^{[0]} + a_1x^{[1]} + a_2x^{[2]}\), where a_0, a_1, and a_2 are constants.
