Answer:

  3 fish, 2 dogs

Step-by-step explanation:

You want a point on the grid representing the solution to the relations, Kingston has 5 pets, and the number of fish is 1 more than the number of dogs.

Each relation can be plotted as a line on the graph:

  f + d = 5 . . . . . . . . the total number of pets is 5

  f = d + 1 . . . . . . . . there is 1 more fish than dogs

The attached plot shows these lines cross at coordinates ...

  (fish, dogs) = (3, 2)

The red circle is the point on the grid that represents the numbers of pets Kingston has.

Additional comment

The equations are plotted only for their respective practical domains. It makes no sense to plot numbers of pets in a range outside 0 to 5.

Answer:

140608 cubic in

Step-by-step explanation:

\(x+x+h=156\)

\(h=156-2 x\)

\(V=x^{2} h \quad\) We eliminate one of the variables

\(V=x^{2}(156-2 x)\)

\(V=156 x^{2}-2 x^{3}\) Differentiating \(v\)

\(V^{\prime}=312x-6 x^{2} \quad\( When \)V=0\)

\(312x-6 x^{2}=0\)

\(x(312-6 x)=0 \quad=\quad\left\{\begin{array}{l}x=0 \\ x=52 \quad x=0 \text { not acceptable }\end{array}\right.\)

\(h=156-2(52)=\Rightarrow h=52\)

\(V=52\times52\times52= 140608 \text{ cubic in}\)

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

a hexagon has 6 sides , then

sum = 180° × (6 - 2) = 180° × 4 = 720°

12

the polygon has 5 sides , so

sum = 180° × (5 - 2) = 180° × 3 = 540°

sum the interior angles and equate to 540

y + 90 + 120 + 90 + 110 = 540

y + 410 = 540 ( subtract 410 from both sides )

y = 130

13

the polygon has 7 sides , so

sum = 180° × (7 - 2) = 180° × 5 = 900°

sum the interior angles and equate to 900

p + 90 + 141 + 130 + 136 + 123 + 140 = 900

p + 760 = 900 ( subtract 760 from both sides )

p = 140

A probability density function, also known as the density of a continuous random variable, is a function used in probability theory whose value at any given sample (or point) in the sample space can be interpreted as giving a relative likelihood that the random variable's value would be close to that sample. While the absolute likelihood of a continuous random variable taking on any given value is 0, probability density (PDF) at two different samples can be used to infer, in any given draw of the random variable, how much more likely it would be that the random variable would be close to one sample compared to the other sample.

We have,

f(x) = xe^(-x)             x>0

= 0                     o.w.

Consider,

\(E(X) = \int\limits^a_0 {xf} (x)\, dx \\\\E(X) = \int\limits^a_0 {xxe}^{-x} \, dx \\\\E(X) = \int\limits^a_0 {x}^{2}e^{-x} \, dx \\\\E(X) = \int\limits^a_0 {x}^{b-1}e^{-mx} \, dx = \frac{n}{m^{n} } \\\\= 2! = 2\)

Answer:

The polygon is a rectangle

Explanation

If you subtract the y-values of the coordinates that have the same x-values, you will get one of the sides of polygon. Then, if you subtract the x-values of the coordinates that have the same y-values, you will get the other side of the polygon. Since this has only 4, sides with a right angle. It must be a rectangle or square. but seeing that the sides are different, the polygon must be a rectangle

Answer:

First, we would need to find the slope for all equations.

Given points, (0,4) and (8,11), we use the formula:

y2 - y1

_____

x2 - x1

Replace values;

11 - 4        7

____ = ____, 7/8 is the slope for function A.

8 - 0        8

Now on the graph for function, B:

Select any two random points, and apply the formula we used for function A(unless you can eye the slope, but double check in case.)

Two random points on this graph, (0,0) and (1, -4)

y2 - y1

______

x2 - x1

Replace values;

-4 - 0         -4

_____ = _____, = -4/1 is the slope for function B.

1 - 0           1

Now, for function C, it is already formatted in slope intercept form, so it's easy to figure out the slope;

(y = mx + b), our equation → y = -3/4x + 5/4

(I'm going to define these variables for you)

y = independent variable

x = dependent variable

y depends on x

m = slope(rise/run)

b = y-intercept(where the line meets the y-axis)

Now, since I defined these for you, we can see that -3/4 is the slope for function C.

Now, let's order these.

-4 by far, is the least slope.

-3/4, is the second least slope.

And last but not least, is 7/8 which is our greatest slope

So it'll be ordered:

Answer:

Step-by-step explanation:

The solution to the system of equations, -x + y = 3 and 4x + y = 8 is: x = 1, y = 4.

If we are given two equations in a system, such as:

-x + y = 3 --> eqn. 1

4x + y = 8 --> eqn. 2

To solve by substitution, rewrite equation 1:

-x + y = 3

y = 3 + x --> eqn. 3

Substitute the value of y into equation 2:

4x + (3 + x) = 8

4x + 3 + x = 8

5x + 3 = 8

5x = 8 - 3

5x = 5

x = 1

Substitute the value of x into eqn. 3:

y = 3 + 1

y = 4

The solution is x = 1, y = 4.

Each piece Measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.

When a particular angle is cut into nine equal parts, the measure of each piece needs to be calculated.

Therefore, it is essential to first calculate the total angle measure and then divide it by the number of parts into which it is being cut.

What is an Angle?

An angle is a geometrical shape that consists of two rays sharing a common endpoint. The common endpoint is known as the vertex, and the two rays are known as the arms of the angle. An angle can be measured in degrees, radians, or gradians. Degrees are the most commonly used unit of measuring angles.How to Calculate Each Piece Measurement of an Angle if Cut into 9 Equal Lengths

To determine each piece measurement of an angle if cut into nine equal lengths, we will need to carry out the following steps:

Step 1: Calculate the total angle measure Suppose the angle being cut into nine equal lengths is an obtuse angle measuring 120 degrees. In that case, the total angle measure will be 120 degrees.

Step 2: Divide the total angle measure by the number of parts into which it is being cut.120 degrees ÷ 9 = 13.3333 degrees

Step 3: Add the kerf width to the piece measurements.0.125 x 9 = 1.125 degrees13.3333 + 1.125 = 14.4583 degrees

Therefore, each piece measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.

The area of the square is given by the  quadratic expression:

\(A = 9x^2 - 6xy + y^2\)

If we have a square whose side measures S, the area of said square is given by the equation:

\(A = S^2\)

In this case, we know that the side length of our square is given by:

\(S = 3x - y\)

Replacing that in the area equation we get:

\(A = (3x - y)^2\)

Now we just need to expand that product, we will get:

\(A = (3x - y)^2 = (3x)*(3x) + (3x)*(-y) + (-y)*(3x) + (-y)*(-y) \\\\A = 9x^2 - 6xy + y^2\)

Then we can see that the correct option is the last one.

Answer:

Step-by-step explanation:

The formula for calculating the magnitude of an earthquake using the Richter scale is:

   M = log10(A) - log10(A0)

where M is the magnitude, A is the amplitude of the earthquake, and A0 is a reference amplitude. The reference amplitude is 1 micron at a distance of 100 km from the epicenter.

For a major earthquake with a rating of 6, we can assume that the amplitude is 1 meter (or 1,000,000 microns), since the Richter scale is logarithmic. Substituting these values into the formula, we get:

   6 = log10(1000000) - log10(1)

Simplifying:

   6 = 6 - 0

Therefore, x = 1 meter, rounded to the nearest hundredth.

Answer: Yes, your calculation of P(A1 OR A2 OR A3) is correct.

Step-by-step explanation: Your calculation of P(A1 OR A2 OR A3) is correct.

To calculate P(X=2), you can use the formula:

P(X=2) = P(A1 AND A2 AND NOT A3) + P(A1 AND A3 AND NOT A2) + P(A2 AND A3 AND NOT A1)

This is because to have precisely two defects, we need two events A1, A2, and A3 to occur and one not to occur.

You cannot simply sum the intersections P(A1 AND A2) + P(A2 AND A3) + P(A1 AND A3) and subtract P(A1 AND A2 AND A3) to get P(X=2), because this will overcount the cases where all three defects occur together.

Instead, you can use the formula above, and note that:

P(A1 AND A2 AND NOT A3) = P(A1 AND A2) - P(A1 AND A2 AND A3)

P(A1 AND A3 AND NOT A2) = P(A1 AND A3) - P(A1 AND A2 AND A3)

P(A2 AND A3 AND NOT A1) = P(A2 AND A3) - P(A1 AND A2 AND A3)

Substituting these into the formula, we get:

P(X=2) = (P(A1 AND A2) - P(A1 AND A2 AND A3)) + (P(A1 AND A3) - P(A1 AND A2 AND A3)) + (P(A2 AND A3) - P(A1 AND A2 AND A3))

which gives us the correct answer for P(X=2).
