c refers to the longest side (hypotenuse) whereas a and b referes to the two other smaller sides of atriangle.

pythagoras theorem

a^2 + b^2 = c^2

11.6^2 + x^2 = 19.2^2

The smallest positive integer Joelle could have multiplied 756 by

15876

This is further explained below.

What is a perfect square?

Generally, A perfect square number is a number in mathematics that, when its square root is calculated, yields a natural number.

To solve this problem we can do:

By properties of roots

So, so that the multiplication of 756 by an integer becomes a perfect square, you have to multiply it by 21 to make $21^2$ and thus "eliminate" the root.

756 * 21=15876

In conclusion,  You can verify that 15876is a perfect square since root (15876)=132 and 132 is a natural number

The generating function for the sequence {an} is given by a(x) = (1 + 2x) / (1 - x - 6x^2). It captures the terms of the sequence {an} as coefficients of the powers of x.

To find the generating function of the sequence {an}, we can use the properties of generating functions and solve the given recurrence relation.

The given recurrence relation is: an = an-1 + 6an-2

We are also given the initial conditions: a0 = 1 and a1 = 3.

To find the generating function, we define the generating function A(x) as:

a(x) = a0 + a1x + a2x² + a3x³ + ...

Multiplying the recurrence relation by x^n and summing over all values of n, we get:

∑(an × xⁿ) = ∑(an-1 × xⁿ) + 6∑(an-2 × xⁿ)

Now, let's express each summation in terms of the generating function a(x):

a(x) - a0 - a1x = x(A(x) - a0) + 6x²ᵃ⁽ˣ⁾

Simplifying and rearranging the terms, we have:

a(x)(1 - x - 6x²) = a0 + (a1 - a0)x

Using the given initial conditions, we have:

a(x)(1 - x - 6x²) = 1 + 2x

Now, we can solve for A(x) by dividing both sides by (1 - x - 6x^2²):

a(x) = (1 + 2x) / (1 - x - 6x²)

Therefore, the generating function for the given sequence is a(x) = (1 + 2x) / (1 - x - 6x²).

True. Symmetric Confidence intervals are used to draw conclusions about two-sided hypothesis tests.

Confidence intervals are used to estimate the range of plausible values for a population parameter (e.g., mean, proportion) based on a sample.

Symmetric confidence intervals assume that the distribution of the population parameter is symmetric and can be approximated by a normal distribution.

When we use a two-sided hypothesis test, we test whether the population parameter is different from a hypothesized value, so we need to estimate both the lower and upper bounds of the plausible range of values.

This is where symmetric confidence intervals are useful. They provide a range of values symmetrically around the point estimate, which can be used to draw conclusions about a two-sided hypothesis test.

The foci are located a \((\sqrt{(7/6)} , 0)\)  and\((-\sqrt{(7/6), } 0).\)

The equation\(6x^2 = y^2\) represents a hyperbola.

To find the vertices and foci, we need to first put the equation in standard form.

Dividing both sides by 6, we get:

\(x^2/(1/6) - y^2/6 = 1\)

Comparing this to the standard form of a hyperbola:

\((x-h)^2/a^2 - (y-k)^2/b^2 = 1\)

We see that \(a^2 = 1/6\) and \(b^2 = 6,\) which means\(a = \sqrt{(1/6) }\) and \(b = \sqrt{6}\)

The center of the hyperbola is (h,k) = (0,0), since the equation is symmetric around the origin.

The vertices are located on the x-axis, and their distance from the center is\(a = \sqrt{(1/6). }\)

Therefore, the vertices are at\((\sqrt{(1/6)} , 0) and (-\sqrt{(1/6)} , 0).\)

The foci are located on the x-axis as well, and their distance from the center is c, where \(c^2 = a^2 + b^2.\)

The type of conic section represented by the equation 6x^2 = y^2 is a hyperbola. To find the vertices and foci of this hyperbola, we first need to rewrite the equation in standard form.

We can do this by dividing both sides by 36, giving us x^2/1 - y^2/6 = 1. From this form, we can see that the hyperbola has a horizontal transverse axis, with the vertices located at (-1,0) and (1,0). The foci can be found using the formula c = sqrt(a^2 + b^2), where a = 1 and b = sqrt(6). Plugging these values in, we get c = sqrt(7), so the foci are located at (-sqrt(7), 0) and (sqrt(7), 0).
The given equation is 6x^2 = y^2. To identify the conic section, we'll rewrite the equation in the standard form: (x^2/1) - (y^2/6) = 1. Since we have a subtraction between the two squared terms, this is a hyperbola.

Therefore for a hyperbola with a horizontal axis, the vertices are at (±a, 0). So, the vertices are at (±1, 0), or (1, 0) and (-1, 0) and,  the foci are at (±c, 0), or (±√7, 0), which are (√7, 0) and (-√7, 0).

Based on the given scenario, the appropriate conclusion is option 5) "We did not find enough evidence to say a significant difference exists between the true average fuel economy today and 22.74 MPG." This conclusion is drawn from the fact that the p-value of 0.6901 is greater than the 5% level of significance, which means that we fail to reject the null hypothesis.

Therefore, we cannot conclude that the true average fuel economy today is significantly different from 22.74 MPG. It is important to note that a random sample of data was used in this hypothesis test to draw a conclusion about the population.
To answer this question, let's look at the given information and the 5% level of significance:

1. You have a null hypothesis (H) that states the average fuel economy today is equal to 22.74 MPG.
2. The alternative hypothesis (ui) states that the average fuel economy today is not equal to 22.74 MPG.
3. You performed a hypothesis test on a random sample of data and found a p-value of 0.6901.
4. You are asked to conclude at the 5% level of significance, which means you would reject the null hypothesis if the p-value is less than 0.05.

Since the observed p-value (0.6901) is greater than the 5% level of significance (0.05), you fail to reject the null hypothesis. This means there is not enough evidence to say a significant difference exists between the true average fuel economy today and 22.74 MPG.

So, the appropriate conclusion is:

5) We did not find enough evidence to say a significant difference exists between the true average fuel economy today and 22.74 MPG.

The median represents the middle value of the data 5.8 feet will be the middle value.

The median represents the middle value in a dataset. The median is important because it gives us an idea of where the center value is located in a dataset. The median tends to be more useful to calculate than the mean when a distribution is skewed and/or has outliers.

Given that apod of dolphins contains 800 dolphins of different ages and lengthens. The median length of dolphins in this pod is 5.8 feet.

From the definition, we can see that of the 800 dolphins the length of the middle dolphin is 5.8 feet because it is a median and the upper values will be greater than 5.8 feet and below it all the dolphins will have smaller lengths.

Step-by-step explanation: The point (-2, 4) is on the circle (x - 5)^2 + (y + 3)^2 = 25. To check if a point is on the circle, we can substitute the point's x and y coordinates into the equation of the circle. If the equation is true, then the point is on the circle. In this case, substituting (-2, 4) into the equation of the circle.

(x - 3)(x + 5) + (x - 3)(2x - 1)

We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1

The median of the weight of the male dogs is M = 65 lb

The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points

Arrange the data points from smallest to largest.

If the number of data points is odd, the median is the middle data point in the list.

If the number of data points is even, the median is the average of the two middle data points in the list.

Given data ,

Let the weights of the male dogs be represented as set A

where the value of A is

Set A = { 45, 50, 52, 58, 62, 68, 72, 78, 81, 95 }

On simplifying , we get

The number of terms = 10

So , the median M = ( 62 + 68 ) / 2

The median M = 130/2 = 65 lb

where the mean is C = 66.1 lb

Hence , the median is M = 65 lb
