To find the answer, we need to identify the quartiles of the data set and use them to construct the box plot.

First, we need to order the data set in increasing order:

10, 15, 20, 25, 30, 35, 40, 45, 50, 55

Next, we need to find the median (Q2) of the data set. Since we have an even number of data points, we take the average of the two middle values:

Q2 = (25 + 30) / 2 = 27.5

This value represents the median of the data set.

To find Q1 and Q3, we divide the data set into two halves:

10, 15, 20, 25, 30 | 35, 40, 45, 50, 55

Q1 is the median of the lower half:

Q1 = (15 + 20) / 2 = 17.5

Q3 is the median of the upper half:

Q3 = (45 + 50) / 2 = 47.5

We can now use this information to construct the box plot:

     |         -------

     |        /

     |    -------

     |   /

     |-------

     |         10    20    30    40    50

            Q1          Q2         Q3

The box represents the middle 50% of the data (from Q1 to Q3), while the whiskers represent the minimum and maximum values that are not outliers.

Since we want to find the paint time for a student who is slower than 75% of the other students, we need to look at the upper quartile (Q3) of the data set. 75% of the data is contained between Q1 and Q3, so a student who is slower than 75% of the other students would have a paint time greater than Q3.

Therefore, the answer is 46 minutes, which is greater than Q3 (47.5 minutes).

The probability of exactly 12 from 39 college students majoring in STEM is \(0.1776\)

To find the probability of exactly 12 out of 39 college students majoring in STEM, we can use the binomial probability formula.

The formula is P(X=k) = (n choose k) * p^k * (1-p)^(n-k).

Data;

n = 39, k = 12, p = 0.26, and (n choose k) = 39 choose 12 = 3,720.

Plugging in the values:

P(X=12) = 3,720 * 0.26^12 * 0.74^27

P(X=12) ≈ 0.1776

To determine if the bolts vary by more than the required variance, we can conduct a hypothesis test. The null hypothesis (H₀) states that the variance of the bolts is equal to or less than the required variance (σ² ≤ 0.025), while the alternative hypothesis (H₁) states that the variance is greater than the required variance (σ² > 0.025).

Next, we need to determine the critical value(s) of the test statistic. Since we are testing for variance, we will use the chi-square distribution. For a one-tailed test with α = 0.01 and 14 degrees of freedom (n-1), the critical value is 27.488.

Now, we can compare the test statistic to the critical value. The test statistic is calculated as (n-1) * s² / σ², where n is the sample size (15), s² is the sample variance (0.1587²), and σ² is the required variance (0.025).

If the test statistic is greater than the critical value, we reject the null hypothesis and conclude that the bolts vary by more than the required variance. Otherwise, we fail to reject the null hypothesis.

The required quadratic equation is: \(2x^2 + 4x - 30\)

A second-order polynomial equation with just one variable, x, is referred to as a quadratic equation. with a ≠ 0 . The fundamental theorem of algebra guarantees that it has at least one solution since it is a second-order polynomial equation. The solution might be real or hard.

The quadratic equation with roots 3 and -5 and a leading coefficient of 2 can be written as:

\(2(x - 3)(x - (-5))\)

Simplifying, we get:

\(2(x - 3)(x + 5)\)

Expanding, we get:

\(2(x^2 + 5x - 3x - 15)\)

\(2(x^2 + 2x - 15)\)

The solution to the given system of inequalities is the region below the line y = (-1/3)x - 1 and to the right of the vertical line x = 3.

To determine the region that represents the solution to the given system of inequalities, we need to graph the individual inequalities and identify the overlapping region.

Let's start with the first inequality: x + 3y < -3. To graph this inequality, we can first rewrite it in slope-intercept form:

3y < -x - 3

Next, isolate y by dividing both sides of the inequality by 3:

y < (-1/3)x - 1

This inequality represents a line with a slope of -1/3 and a y-intercept of -1. We can plot this line on a coordinate plane.

Next, let's graph the second inequality: x > 3. This inequality represents a vertical line passing through x = 3.

Now, we need to determine the overlapping region between the two graphs. Since we have a strict inequality (less than) for the first inequality, the region below the line represents the solution set.

Combining both graphs, we find that the solution to the given system of inequalities is the region that lies below the line y = (-1/3)x - 1 and to the right of the vertical line x = 3.

Answer: (5,-2)

Step-by-step explanation:

I'm assuming the equations are:

Y=-(6/5)x +4

y = -(1/5)x -1  [Note that I changed "y-" to just "y."]

We can solve this in one of two ways:  Mathematically and Graphically.

Math:  

y = -(1/5)x -1

6y = -(6/5)x -6

-(Y=-(6/5)x +4)

5y = -10

y = -2

y = -(1/5)x -1

-2 = -(1/5)x -1

-1 = -(1/5)x

5 = x

x = 5

Answer:b

Answer:B

Step-by-step explanation:

ΔABC is translated by 4 units to the right to become ΔA'B'C'. Then ΔA'B'C' is reflected over the y-axis to become ΔA"B"C". Because the transformations are rigid transformations, the pre-image and image are congruent.

In transformations, there are different types such as translation, reflection, dilation e.t.c.

Now, the transformation from ΔABC to ΔA'B'C'  is a translation by 4 units to the right because we see that the shape and dimensions are preserved and the coordinates change by the transformation rule;

(x, y) → ((x + 4), y)

The second transformation is simply a reflection over the x-axis as we see that all the y-values are negated.

Thus, the final transformation from ΔA'B'C' to ΔA"B"C" follows the transformation rule (x, y) → (x, -y)

Answer:

x = 5 , ML = 18

Step-by-step explanation:

the midsegment NP of the trapezoid is half the sum of the bases, that is

NP = \(\frac{JK+ML}{2}\)

25 = \(\frac{4x-2+6x+2}{2}\) ( multiply both sides by 2 to clear the fraction )

50 = 10x ( divide both sides by 10 )

5 = x

Then

ML = 4x - 2 = 4(5) - 2 = 20 - 2 = 18

Recovering low-rank structures via eigenvector perturbation analysis is a common problem in statistical machine learning, such as in factor analysis, community detection, ranking, matrix completion, among others.

While a large variety of bounds are available for average errors between empirical and population statistics of eigenvectors, few results are tight for entrywise analyses, which are critical for a number of problems such as community detection.

This paper investigates entrywise behaviors of eigenvectors for a large class of random matrices whose expectations are low-rank, which helps settle the conjecture in Abbe et al. (2014b) that the spectral algorithm achieves exact recovery in the stochastic block model without any trimming or cleaning steps. The key is a first-order approximation of eigenvectors under the ℓ∞ norm:

\(u_{k }\)≈1/ λ (\(\frac{A u^*_{k}}{*k}\))

where {uk} and {u∗k} are eigenvectors of a random matrix A and its expectation EA, respectively. The fact that the approximation is both tight and linear in A facilitates sharp comparisons between uk and u∗k. In particular, it allows for comparing the signs of uk and u∗k even if ∥uk−u∗k∥∞ is large. The results are further extended to perturbations of eigenspaces, yielding new ℓ∞-type bounds for synchronization (Z2-spiked Wigner model) and noisy matrix completion.

Data reduction techniques can be applied to both rows (observations) and columns (variables) in a given dataset. Data reduction techniques like Principal Component Analysis (PCA) and Factor Analysis are applied to variables in order to reduce the number of variables and extract relevant information from them. These techniques aim to identify underlying factors or components that explain the variance in the data and represent them in a lower-dimensional space. Similarly, techniques like clustering and outlier detection can be applied to observations in order to group similar observations together or identify outliers.

Therefore, data reduction can be applied to both rows and columns, depending on the analysis goals and data characteristics.
