The remaining number of windows is given by the equation A = 11 windows

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The total number of windows that needs to be washed = 30 windows

The number of windows that was washed before lunch = ( 2/5 ) of the total

Substituting the values in the equation , we get

The number of windows that was washed before lunch = ( 2/5 ) x 30

The number of windows that was washed before lunch = 2 x 6

The number of windows that was washed before lunch = 12 windows

So , the remaining number of windows = 30 - 12 = 18 windows

And ,

The number of windows that was washed after lunch = 7 windows

So , the remaining number of windows that needs to be washed A = remaining number of windows - number of windows that was washed after lunch

On simplifying the equation , we get

The remaining number of windows that needs to be washed A = 18 - 7

The remaining number of windows that needs to be washed A = 11 windows

Hence , the equation is A = 11 windows

The false statement regarding the trigonometric ratios is given as follows:

In △ABE, the sin(A) is the same as the tan(F) in △ACF because the triangles are 45-45-90 triangles and therefore similar.

The three trigonometric ratios are defined as follows:

For similar triangles, the ratios are equal, as the side lengths are proportional.

In a 45-45-90 triangle, the sine is equals to the cosine.

However, similar triangles have different values of sine and tangent, hence the first statement is false.

The most important part of the design cycle is the "Iteration" phase.

In this phase, the designer goes back and forth between testing and evaluating the design, making changes, and testing again until the desired outcome is achieved.

In mathematical terms, the iteration phase can be seen as an optimization process, where the designer seeks to minimize the difference between the desired and actual outcomes.

This phase is crucial because it allows the designer to identify and resolve any issues with the design, ensuring that the final product is functional and meets the desired specifications.

In conclusion, the iteration phase of the design cycle is essential for ensuring that the final design is effective, efficient, and meets all the requirements. The designer must repeat this phase multiple times to achieve the desired outcome and ultimately improve the overall design.

The linear correlation coefficient between the length of the right humerus and the length of the right tibia is 0.517.

To compute the linear correlation coefficient between the length of the right humerus and the length of the right tibia, we will use the formula: r = (n∑xy - (∑x)(∑y)) / sqrt([(n∑x^2 - (∑x)^2)(n∑y^2 - (∑y)^2)])

Where r is the correlation coefficient, n is the number of observations, x is the length of the right humerus, and y is the length of the right tibia.

First, we will calculate the sum of x, y, xy, x^2, and y^2:

∑x = 24.8 + 24.59 + 24.59 + 24.29 + 23.81 + 24.87 + 25.90 + 26.11 + 26.63 + 26.31 + 26.84 = 278.74

∑y = 65.05 + 35.57 + 35.57 + 34.58 + 34.20 + 34.73 + 37.38 + 37.96 + 37.46 + 37.75 + 38.50 = 428.75

∑xy = (24.8)(65.05) + (24.59)(35.57) + (24.59)(35.57) + (24.29)(34.58) + (23.81)(34.20) + (24.87)(34.73) + (25.90)(37.38) + (26.11)(37.96) + (26.63)(37.46) + (26.31)(37.75) + (26.84)(38.50) = 10659.01

∑x^2 = (24.8)^2 + (24.59)^2 + (24.59)^2 + (24.29)^2 + (23.81)^2 + (24.87)^2 + (25.90)^2 + (26.11)^2 + (26.63)^2 + (26.31)^2 + (26.84)^2 = 7221.47

∑y^2 = (65.05)^2 + (35.57)^2 + (35.57)^2 + (34.58)^2 + (34.20)^2 + (34.73)^2 + (37.38)^2 + (37.96)^2 + (37.46)^2 + (37.75)^2 + (38.50)^2 = 15738.39

Now we can plug these values into the formula and calculate the correlation coefficient:

r = (11)(10659.01) - (278.74)(428.75) / sqrt([(11)(7221.47) - (278.74)^2][(11)(15738.39) - (428.75)^2])r = 117249.11 - 119475.235 / sqrt([79436.17 - 77691.79][173122.29 - 183744.56])r = -2226.125 / sqrt([1744.38][-10622.27])r = -2226.125 / sqrt(-18525838.35)r = -2226.125 / (-4304.18)r = 0.517

Therefore, the linear correlation coefficient between the length of the right humerus and the length of the right tibia is 0.517.

√(x₁+1)²+(3x₁-5)² =√74

√(x₂+1)²+(3x₂-5)² =√74

Simplifying each equation and solving for x, we get:

x₁ = -4/3 or x₁ = -2

x₂ = 2/3 or  x₂  = -4

Simplifying each equation and solving for x, we get:

x₁ = -4/3 or x₁ = -2

x₂ = 2/3 or x₂ = -4

Substituting each value of x into y = 3x, we get the coordinates of B and C:

B: (-4/3, -4)

C: (2/3, 2)

The rank (m) and the nullity (n) is the Matrix A is 5 and 3 respectively according to the planes given.

The maximum number of its linearly independent columns (or rows ) of a matrix is called the rank of a matrix. And the dimension of the null space of A, also called the kernel of A.

Given null space of [tex]L_{A}[/tex] is a plane in [tex]lR^{3}[/tex] .

So nullity of matrix A is A = 2

Since the dimensions of a plane in [tex]lR^{3}[/tex] is 2.

The critical value for the 0.05 level of significance is k = 21.

To find the critical value, we can use the binomial distribution. The binomial distribution models the number of successes in n independent Bernoulli trials, each with probability p of success. In this case, the number of successes is the number of dog owners who say Woof Chow is their regular brand, and the number of trials is n = 100. The null hypothesis is that the true market share of Woof Chow is 25%, and the alternative hypothesis is that it is not 25%.

We can use the binomial cumulative distribution function (CDF) to find the critical value. The CDF gives the probability of getting k or fewer successes in n trials, given a probability of success p. The critical value is the smallest value of k such that the CDF at k is greater than or equal to 1 - alpha, where alpha is the level of significance. In this case, alpha = 0.05.

So, we want to find the smallest k such that:

P(X <= k) >= 1 - 0.05

where X is a random variable representing the number of dog owners who say Woof Chow is their regular brand. We can use a binomial calculator or a software package to calculate the binomial CDF, or we can use a table of critical values for the binomial distribution.

The critical value for the 0.05 level of significance is k = 21. This means that if the true market share of Woof Chow is 25%, then the probability of getting 23 or more dog owners who say Woof Chow is their regular brand is less than 0.05. Since the observed number of dog owners who say Woof Chow is their regular brand is 23, which is greater than 21, we can reject the null hypothesis that the true market share is 25%.

This means that based on the survey results, we cannot conclude that Woof Chow has a market share of 25%. The survey results suggest that Woof Chow may have a market share that is greater than 25%.
