The solution of the equations 6x = 52 − 2y and 5x + 7y = 70 by elimination method will be (7, 5).

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

The equations are given below.

6x = 52 - 2y

6x + 2y = 52

3x + y = 26                   ...1

5x + 7y = 70

(5/7)x + y = 10              ...2

Subtraction equation 2 from equation 1, then we have

3x - (5/7)x = 26 - 10

(16/7)x = 16

x = 7

Then the value of 'y' is given as,

3(7) + y = 26

21 + y = 26

y = 5

\(4^{-11/3 -(-2/3)=4^{-11/3 + 2/3}=4^{-3}=1/64\)

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

Therefore, from the options given correct one is 4.

Answer:

51/60

Step-by-step explanation:

First, I'll convert 5 1/10 into an improper fraction to make it easier to work with. I get 51/10. Then, I multiply the two fractions like so:

51/10 * 1/6 = 51/60

You multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom) separately.

So the answer is 51/60.

Answer 1008

Step-by-step explanation:

Answer:

If m is parallel to n and n is perpendicular to p, then m is perpendicular to p.

Step-by-step explanation:

If you draw m parallel to n and then you run a line p through n such that n and p are perpendicular. The line p will also cross over m since lines go on forever and it will be perpendicular to m as well.

The component form of the following vectors is Option A. V = (38.3, 32.1).

To find the component form of a vector given its magnitude and direction angle, we can use trigonometry.

The component form of a vector in two dimensions is represented as (x, y), where x is the horizontal component and y is the vertical component.

In this case, the magnitude of the vector is given as 50, and the direction angle θ is 50°. We can use this information to calculate the horizontal and vertical components.

The horizontal component (x) can be found using the formula x = magnitude * cos(θ), and the vertical component (y) can be found using y = magnitude * sin(θ).

Let's calculate the components:

x = 50 * cos(50°) ≈ 38.3

y = 50 * sin(50°) ≈ 32.1

Rounding the answers to the nearest tenth, we get the component form of the vector V as (38.3, 32.1).

Therefore, the correct answer is A. V = (38.3, 32.1).

Answer:

The sample size is of 366.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which

z is the z-score that has a p-value of \(1 - \frac{\alpha}{2}\).

The margin of error is of:

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

A preliminary sample showed that 30.0% of the families in this sample own this company's product.

This means that \(\pi = 0.3\)

95% confidence level

So \(\alpha = 0.05\), z is the value of Z that has a p-value of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).

The sample size that would limit the margin of error to be within 0.047 of the population proportion is:

This is n for which \(M = 0.047\). So

\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)

\(0.047 = 1.96\sqrt{\frac{0.3*0.7}{n}}\)

\(0.047\sqrt{n} = 1.96\sqrt{0.3*0.7}\)

\(\sqrt{n} = \frac{1.96\sqrt{0.3*0.7}}{0.047}\)

\((\sqrt{n})^2 = (\frac{1.96\sqrt{0.3*0.7}}{0.047})^2\)

\(n = 365.2\)

Step-by-step explanation:

The growth rate of the investment is represented by the constant multiplier in the exponential term of the formula y = 20000(1.035)x. In this case, the constant multiplier is 1.035, which represents the annual growth rate of the investment account.

To calculate the growth rate as a percentage, we can subtract 1 from the constant multiplier, and then multiply the result by 100.

So, the growth rate of the investment is:

1.035 - 1 = 0.035

0.035 * 100 = 3.5%

Therefore, the growth rate of the investment is 3.5%.

The value of a is 5/9 if  y = a(x - 2)(x + 6) and (3,5) is a point on the graph.

It is defined as the graph of a quadratic function that has something bowl-shaped.

(x - h)² = 4a(y - k)

(h, k) is the vertex of the parabola:

a = √[(c-h)² + (d-k²]

(c, d) is the focus of the parabola:

It is given that:

A quadratic relation has the equation y= a(x - s )(x – t).

y = a(x - 2)(x + 6) and (3,5) is a point on the graph

Plug x = 3 and y = 5

5 = a(3 - 2)(3 + 6)

a = 5/9

The parabola has zeros of 4 and -2 and a y-intercept of 1

y= a(x - s )(x – t)

0= a(4 - s )(4 – t)

0= a(-2 - s )(-2 – t)

1= a(0 - s )(0 – t)

No solution.

Similarly, it can find the equation of the parabola in the remaining part,

Thus, the value of a is 5/9 if  y = a(x - 2)(x + 6) and (3,5) is a point on the graph.

Answer:

No, -8 - 1 - 2 does not equal -9 - 3.

Step-by-step explanation:

The order in which arithmetic operations are performed is important. In this case, we are performing subtraction operations, and according to the order of operations, we should first perform the operation inside the parentheses, then the operations that come after it.

Therefore, the correct order of operations for the expression -8 - 1 - 2 is:

(-8 - 1) - 2 = -9 - 2 = -11

On the other hand, the expression -9 - 3 would be evaluated as:

-9 - 3 = -12

Therefore, -8 - 1 - 2 does not equal -9 - 3.

The triangle XYZ is formed by the next points:

X=(2, 5) Y=(0, 2) Z=(3,1)

The transformations that have occurred in the XYZ triangle are:

1. A reflection over the x-axis.

It will result in a change on the sign of the x-coordinate, then the new coordinates are (-x, y):

X'=(-2, 5) Y'=(0, 2) Z'=(-3,1)

2. A translation of 3 units to the right and 5 units down.

Then, the new coordinates are given by (x+3, y-5)

X'=(-2+3, 5-5) Y'=(0+3, 2-5) Z'=(-3+3,1-5)

X'=(1, 0) Y'=(3, -3) Z'=(0,-4)

Since \(x^2 + x + 1 = 0\) means \(x^2+x = -1\), we have for any \(n\) the recursive relation

\(x^n (x^2 + x) = x^{n+2} + x^{n+1} = -x^n \implies x^{n+2} = -x^{n+1} - x^n\)

Let \(f(x)=x^{2015}+x^{2013}+x\). Substitution using the recursive rule generates an alternating power-reduction pattern:

\(f(x) = \left(-x^{2014} - x^{2013}\right) + x^{2013} + x = -x^{2014} + x\)

\(f(x) = -\left(-x^{2013} - x^{2012}\right) + x = x^{2013} + x^{2012} + x\)

\(f(x) = \left(-x^{2012} - x^{2011}\right) + x^{2012} + x = -x^{2011} + x\)

\(f(x) = -\left(-x^{2010} - x^{2009}\right) + x = x^{2010} + x^{2009} + x\)

\(f(x) = \left(-x^{2009} - x^{2008}\right) + x^{2009} + x = -x^{2008} + x\)

\(f(x) = -\left(-x^{2007} - x^{2006}\right) + x = x^{2007} + x^{2006} + x\)

and so on.

Notice that in the equivalent forms of \(f(x)\) involving 3 terms, the largest power of \(x\) is a multiple of 3, and the next largest power is 1 less. This means after so many iterations of substitutions, we would end up with

\(f(x) = x^3 + x^2 + x\)

Then by factorizing, the expression of interest reduces to

\(f(x) = x (x^2 + x + 1) = x \times 0 = \boxed{0}\)

The number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters is 6,760,000, option a is correct.

To determine the number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters, we need to consider the possibilities for each element.

For the numbers, we have 10 options (0-9) for each of the four positions, resulting in a total of \(10^4 = 10,000\) combinations.

For the letters, we have 26 options (A-Z) for each of the two positions, resulting in a total of \(26^2 = 676\) combinations.

To find the total number of different plates, we multiply the number of possibilities for each element:

\(10,000 \times 676 = 6,760,000\).
