If the scatter plot shows no discernible relationship between the variables and the points appear randomly scattered, then the r-value of 0.01 is accurate. However, if there is a visible relationship, the value of r may need to be recalculated or checked for errors in data input or analysis.

To find whether a correlation coefficient of r = 0.01 is an accurate value for the data based on the scatter plot, it's essential to consider the following factors:

1. Visual inspection of the scatter plot: Observe the overall pattern of data points in the scatter plot. If the points seem randomly scattered with no discernible pattern, then a correlation coefficient close to 0, such as r = 0.01, would be accurate. However, if there is a clear linear or non-linear relationship between the variables, the value of r = 0.01 may not be accurate.

2. Strength of the relationship: The correlation coefficient r ranges from -1 to 1, where -1 represents a strong negative relationship, 0 represents no relationship, and 1 represents a strong positive relationship. An r-value of 0.01 indicates a very weak or no relationship between the variables. Confirm that this is consistent with the scatter plot pattern.

To determine if the r-value of 0.01 is accurate for the data, carefully examine the scatter plot and consider these factors. If the scatter plot shows no discernible relationship between the variables and the points appear randomly scattered, then the r-value of 0.01 is accurate. However, if there is a visible relationship, the value of r may need to be recalculated or checked for errors in data input or analysis.

This shows that they read less frequently than 95.7% of their classmates in the same grade level.

In statistics, a percentile is a metric that is used to express where one observation stands in relation to a larger group of data. It displays the proportion of data points that fall under a given value. For instance, if a student achieves a score in the 90th percentile on a standardised test, it signifies that they outperformed 90% of their peers who also took the test. As an alternative, if a child is taller than 25% of children their age and shorter than 75%, their height is in the 25th percentile for their age.

given

We must first compute the z-score using the following formula to determine the percentile of the child's reading proficiency.

z = (x - μ) / σ

where x represents the child's reading rate, represents the grade-level mean reading rate, and represents the standard deviation.

Inputting the values provided yields:

z = (46.2 - 85) / 22

z = -1.727

We can calculate or use a conventional normal distribution table to obtain the value of 0.0428 for the region to the left of z = -1.727. The child's reading rate is at the 4.28th percentile according to this statistic.

As a result, the child's reading proficiency is 4.3 percentile (rounded to one decimal place).

This shows that they read less frequently than 95.7% of their classmates in the same grade level.

Answer:

She is 11, turning 12. She was born in 2009.

Step-by-step explanation:

T is the linear transformation described by T(w,z) in L(C2). This indicates that the linear transformation T changes two-dimensional vectors of the type (w,z) to (-z,w).

To get T's eigenvalues, solve the equation T(v) = v, where is the eigenvalue and v is the eigenvector. By solving this equation, we discover that T's eigenvalues are λ1 = -1 and λ2 = 1.

For each eigenvalue, the associated eigenspaces are the subspaces of C2 that are spanned by the eigenvectors of T. The eigenspace is the subspace covered by the eigenvector λ1= -1 is (1,0). The eigenspace is the subspace spanned by the eigenvector λ2= 1 is (0,1).

As a result, the subspaces covered by (1,0) and (1,1) are the generalized eigenspaces corresponding to the different eigenvalues of T. (0,1).

Step-by-step explanation:

;)

The values for the given expressions giving a = i +5j and b = -4i - j, is as follows:
a + b = -3i + 4j + 3k
2a + 3b = -10i + 7j + 11k
|a| = \(\sqrt{30}\)
|a - b| =  \(\sqrt{34}\)

To find the values of a + b, 2a + 3b, |a|, and |a - b|, given the vectors a = i + 5j - 2k and b = -4i - j + 5k, we can perform the necessary vector operations:

a + b = (1i + 5j - 2k) + (-4i - j + 5k)
        = (1 - 4)i + (5 - 1)j + (-2 + 5)k
        = -3i + 4j + 3k

2a + 3b = 2(i + 5j - 2k) + 3(-4i - j + 5k)
            = (2i + 10j - 4k) + (-12i - 3j + 15k)
            = (-10i + 7j + 11k)

|a| = magnitude of vector a = √(i^2 + 5j^2 + (-2k)^2)
    = √(1 + 25 + 4)
    = √30

|a - b| = magnitude of vector (a - b) = √((-3i + 4j + 3k)^2)
   = √(9 + 16 + 9)
   = √34

Therefore, the values are:

a + b = -3i + 4j + 3k

2a + 3b = -10i + 7j + 11k

|a| = √30

|a - b| = √34

Step-by-step explanation:

Let a be adult at premiere.

Let c be children at premiere.

Equation 1:-    a + c = 600

Let 13a be total price of tickets for adults.

Let 2c be total price of tickets for children.

Equation 2:-   13a + 2c = 2630

Solve simultaneously for c to determine children at premiere.

Make c the subject from Equation 1 to get Equation 3.

Equation 3:-  c = 600 - a

Substitute c's value in Equation 3 in Equation 2

13a + 2 (600 - a) = 2630

13a + 1200 -2a = 2630

11a = 2630 -1200

11a  = 1430

a = 130

Substitute value of a in Equation 3

c = 600 - 130

c = 470

Option C. which corresponds to the probability of approximately 0.0771 that there will be 8 occurrences within a period of ten minutes.

This problem follows a Poisson distribution, where the mean and variance of the distribution are equal to λ. Here, λ = 5, and we need to find the probability of having 8 occurrences in 10 minutes. The probability mass function of Poisson distribution is:

P(X = k) = (e⁽⁻λ⁾ * λᵏ) / k!

Substituting the given values, we get:

P(X = 8) = (e⁽⁻⁵⁾ * 5⁸) / 8!

P(X = 8) ≈ 0.0771

The area to the right of z = -1 for the standard normal distribution is approximately 0.8413.

a. To find the area to the right of z = -1 for the standard normal distribution, we need to calculate the cumulative probability using the standard normal distribution table or a statistical calculator.

From the standard normal distribution table, the area to the left of z = -1 is 0.1587. Since we want the area to the right of z = -1, we subtract the left area from 1:

Area to the right of z = -1 = 1 - 0.1587 = 0.8413

Therefore, the area to the right of z = -1 for the standard normal distribution is approximately 0.8413.

The length of each of its sides is 12 inches if the perimeter of a regular hexagon is 72 inches option (B) is correct.

A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

\(\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|\)

Given ,

One angle of the figure as 123°.

Now,

∠C and 123° form linear pair.

So,

∠A= 127°

∠B = 127°

∠C = 57°

b)

Values of ∠D = 98°, ∠E = 98°, ∠F = 98° .

Given one angle as 82°

∠F = 98°

Now,

∠D and ∠F are corresponding angles. Thus,

∠D = ∠F

∠D = 98° .

Now,

∠D and ∠E are vertically opposite angles.

Thus,

∠E = 98°.

Hence,

∠D = 98°

∠E = 98°

∠F = 98°
