The points (3,0) and (3,1) are located on the first line. The point (3,0) is three units to the right of the origin on the x-axis, while the point (3,1) is three units to the right and one unit up from the origin.

To create a number graph that ranges from negative two to ten on both the x and y axes, you would need to draw a grid with 13 horizontal lines and 13 vertical lines, spaced one unit apart. The point (0,0) is located at the center of the graph.

A line passes through the points (0,0) and (3,1). To graph this line, start at (0,0) and move three units to the right and one unit up to reach (3,1). Draw a straight line connecting these two points.

A second line passes through the points (0,7) and (3,1). To graph this line, start at (0,7) and move three units to the right and six units down to reach (3,1). Draw a straight line connecting these two points.

The determinants for the given linear system are |A| = -19, |Ax| = -74, and |Ay| = 57.

A linear system is a collection of one or more linear equations involving one or more variables.

The given linear system's determinants are:

The coefficient matrix determinant, denoted by |A|

The x variable matrix determinant, denoted by |Ax|

The y variable matrix determinant, denoted by |Ay|

To find these determinants, we first need to write the coefficient matrix and the x and y variable matrices.

The coefficient matrix is the matrix of the coefficients of the variables

| 5 2 |

|-3 -5 |

The x variable matrix is obtained by replacing the x column in the coefficient matrix with the constants on the right-hand side of the equations:

| 14 2 |

| 3 -5 |

The y variable matrix is obtained by replacing the y column in the coefficient matrix with the constants:

| 5 14 |

|-3 3 |

Now we can calculate the determinants:

|A| = determinant of the coefficient matrix = (5)(-5) - (-3)(2) = -19

|Ax| = determinant of the x variable matrix = (14)(-5) - (2)(3) = -74

|Ay| = determinant of the y variable matrix = (5)(3) - (14)(-3) = 57

Therefore, the determinants for the given linear system are |A| = -19, |Ax| = -74, and |Ay| = 57.

The p-value of the test statistic is 0.5520

The director of research and development is testing the medicine to see if there is evidence that it relieves pain in more than 390 seconds. To do this, they took a sample of 75 patients, and found that the mean time for the medicine to relieve pain was 398 seconds, with a population variance of 576. The test statistic in this case is the p-value, which can be found using the formula for the Z-score, which is:
Z = (398 - 390) / (√576/75)

Plugging in the numbers, we get:

Z = (398 - 390) / (24/75) = 0.167

Using a Z-table, the p-value of the test statistic is 0.5520. Thus, the p-value of the test statistic is 0.5520, rounded to four decimal places.

Answer:

D. x=-3

Step-by-step explanation:

First of all, it's an equation (=), not an inequality (>). D is the only option that shows the result of an equation :)

Anyway, here you go:

Simplify the equation using PEMDAS. Expand using the distributive property:

\(5(2x)+5(8)=10\\\\10x+40=10\)

Use inverse operations to isolate the variable. Subtract 40 from both sides, canceling out the positive 40 on the left:

\(10x+40-40=10-40\\\\10x=-30\)

Isolate the variable using inverse operations. Divide both sides by 10, canceling the 10 out on the left:

\(\frac{10x}{10} =\frac{-30}{10} \\\\x=-3\)

The value of x is -3. The correct answer is (D).

The area enclosed by the figure is 6425 square meters.

The area enclosed by the figure is made up of a square of 50m x 50m = 2500 m^2 There are four semicircles attached to each side of the square.

Each semicircle has a radius of 25m, so the area of each semicircle is,

(1/2) * pi * 25^2

= (1/2) * 3.14 * 625 m^2.

The total area of the four semicircles is,

4 * (1/2) * 3.14 * 625 m^2

= 2 * 3.14 * 625 m^2

= 3925 m^2

To find the total area enclosed by the figure, add the area of the square to the area of the semicircles:

2500 m^2 + 2 * 3.14 * 625 m^2

= 2500 m^2 + 3950 m^2

Answer:

The answer is 12, I would know because I just took it

Step-by-step explanation:

The variance of P(T ≤ 25) is equal to 0.6431 * (1 - 0.6431), which is approximately 0.2317 (rounded to four decimal places).

In a Poisson process with arrival rate λ, the waiting time until the k-th arrival follows a gamma distribution with parameters k and 1/λ.

In this case, we want to find the waiting time until the third arrival, which follows a gamma distribution with parameters k = 3 and λ = 0.2. The mean and variance of a gamma distribution with parameters k and λ are given by:

Mean = k / λ

Variance = k / λ^2

Substituting the values, we have:

Mean = 3 / 0.2 = 15 minutes

Variance = 3 / (0.2^2) = 75 minutes^2

So, the mean of T is 15 minutes and the variance of T is 75 minutes^2.

To find P(T ≤ 25), we need to calculate the cumulative distribution function (CDF) of the gamma distribution with parameters k = 3 and λ = 0.2, evaluated at t = 25.

P(T ≤ 25) = CDF(25; k = 3, λ = 0.2)

Using a gamma distribution calculator or software, we can find that P(T ≤ 25) is approximately 0.6431 (rounded to four decimal places).

Therefore, the variance of P(T ≤ 25) is equal to 0.6431 * (1 - 0.6431), which is approximately 0.2317 (rounded to four decimal places).

Step-by-step explanation:

The Volume of the cone with base radius 5cm and Total Surface Area 907cm² is   1374.5cm³.

The Volume of the cone is denoted by

V = (1/3)*π*r²*h

where r = base radius

h = height of the cone

In the given question

the base radius r = 5cm

the total surface area of the cone = 907cm²

Total Surface Area of the cone is denoted by = πr(L+r)

where L is the slant height .

Step1: we first calculate Slant height "L"

Substituting the values in Total Surface Area formula we get

907 = π*5(L+5)

Simplifying further we get

L+5 = 907/5π

L = 907/5π - 5

L = 57.77 - 5

L = 52.77

Step2: Use L to find the height of cone

Using Pythagoras Theorem

L²=r²+h²

(52.77)² = (5)² + h²

Simplifying further we get

2784.67 = 25 +  h²

h² = 2759.67

h = √2759.67

h = 52.53

Step 3: use h to find the Volume

Substituting the value of h and r in Volume formula we get  ,

V = (1/3)*π*5²*52.53

= (1/3)*(3.14)*25*52.53

= 4123.605 / 3

= 1374.535

≅1374.5

Therefore , the volume of the cone is 1374.5cm³.

we have given that the sint=1/8 then we have to find the exact value of

sin(2t) , cos(2t) , and tan(2t).

Here the value of Sint = 18

then sin2t becomes

sin2t = 2*1/8 then

sin2t = 1/4.

And

(Cos2t)^2 = 1 - (Sin2t)^2

(Cos2t)^2 = 1 - 1/16

(Cos2t)^2 = (16 - 1)/16

(Cos2t)^2 = 15/16

(Cos2t) = (15/16)^1/2

To find the length of the longest subsequence within Z that is a blend of two subsequences from X and Y, we can set up a recurrence relation. The recurrence relation involves defining a function and variables. By recursively solving the problem and considering the new function calls, we can determine the length of the longest blend subsequence. Base cases are also defined to handle the termination condition.

To solve the problem of finding the length of the longest blend subsequence in Z, we can define a recursive function. Let's call this function "findLongestBlend" with the input strings X, Y, and Z, and their respective lengths x, y, and z.

The base cases for the recursion are:

If any of the strings X, Y, or Z becomes empty (i.e., x = 0, y = 0, or z = 0), the length of the blend subsequence would be 0.

If the last characters of X and Y are the same as the last character of Z, then the blend subsequence length would be the maximum of:

1 + findLongestBlend(X, Y, Z without the last character)

findLongestBlend(X without the last character, Y, Z without the last character)

findLongestBlend(X, Y without the last character, Z without the last character)

In each recursive call, we reduce the length of X, Y, and Z by removing the last character if it matches with the last character of Z. We consider the three possible cases mentioned above and choose the maximum length among them.

By applying this recursive approach and handling the base cases properly, we can find the length of the longest blend subsequence within Z formed by subsequences from X and Y.
