state four reasons why choice should be made in satisfaction human wants​

Answer:

B is the correct answer

Step-by-step explanation:

A possible set of scores for the students is: 4, 4, 6, 6, 6

We are given that five students took the quiz. If the lowest score is 4 and the highest score is 6, we can say that the set of values ​​can be expressed as:

4, x, y, z, 6

Here we can see that the mode is 6 and the mean is 5.2. Therefore, at least one other student of hers has scored her 6, which could result in:

4, x, y, 6, 6

Therefore:

(4 + x + y + 6 + 6)/5 = 5.2

16+x+y=26

x + y = 10

So the other two numbers are probably 6 and 4, because 6 is the mode, so they can't both be 5.

Step-by-step explanation:

I think that we have to find the lateral area

circumference = 2 x radius x pi = 2 x 4 x pi = 25,13 in^2 (round to the nearest hundreds)

lateral surface = (circumference x slant height)/2 = (25,13 x 6)/2 = 75,39 in^2 (round to the nearest hundreds)

Answer:

A) 4:5

Step-by-step explanation:

A) 4:5

B) 4:9

C) 5:4

D) 5:9

If there are 4 sixth grade students, you can already cross off D because there is no 4 as an option. There are 5 seventh grade students, you can cross off B because there's no 5. So now it's down to 4:5 or 5:4. Since it wants the ration of sixth to seventh, it's 4 to 5.

Hence, the ratio is 4:5, answer A

The linear system X₁ + 2X₂ = 3.21 and 4.02X₁ + IL || -1 = -1 using Cramer's rule, we need to find the values of X₁ and X₂.

To apply Cramer's rule, we first need to calculate the determinant of the coefficient matrix and the determinants of the matrices obtained by replacing each column of the coefficient matrix with the constant terms.

The coefficient matrix is:

| 1   2 |

| 4.02  IL || |

The determinant of the coefficient matrix, denoted as D, is given by:

D = (1 * IL ||) - (2 * 4.02)

  = IL || - 8.04

The matrix obtained by replacing the first column with the constant terms is:

| 3.21   2 |

| -1     IL || |

The determinant of this matrix, denoted as D₁, is given by:

D₁ = (3.21 * IL ||) - (-1 * 2)

   = 3.21IL || + 2

The matrix obtained by replacing the second column with the constant terms is:

| 1   3.21 |

| 4.02  -1 |

The determinant of this matrix, denoted as D₂, is given by:

D₂ = (1 * -1) - (4.02 * 3.21)

   = -1 - 12.9042

   = -13.9042

Now, we can find the values of X₁ and X₂ using the formulas:

X₁ = D₁ / D

X₂ = D₂ / D

Substituting the values we calculated earlier, we have:

X₁ = (3.21IL || + 2) / (IL || - 8.04)

X₂ = (-13.9042) / (IL || - 8.04)

This gives us the solution to the linear system.

Solve the linear system X 1 X1 + 2x2 3.21 + 4.02 IL || -1 -1 = via Cramer's rule if possible.

Answer:

-x² + 6x - 17

Step-by-step explanation:

First, expand (x-3)² using FOIL

(x - 3)(x - 3)

= x² - 6x + 9

Distribute the negative sign to the expression:

-(x² - 6x + 9)

-x² + 6x - 9

Now, subtract 8 from this

-x² + 6x - 9

= -x² + 6x - 17

So, the equation in standard form is -x² + 6x - 17

The answer is.. x^2+6x-17

The length of the diameter circumcised about this isosceles triangle is 32 cm.

To find the length of the circumcircle's diameter, we can use the properties of an isosceles triangle.

In an isosceles triangle, the vertex angle is the angle formed by the two congruent sides. In this case, the vertex angle is given as 120 degrees.

We know that the vertex angle of an isosceles triangle is located opposite the base. Let's denote the base as side a, and the congruent sides as side b.

In an isosceles triangle, the base angles are congruent. Since the sum of the angles in a triangle is 180 degrees, each base angle in this triangle measures (180 - 120) / 2 = 30 degrees.

Now, we can apply the Law of Sines to find the length of the base, side a. The Law of Sines states:

a/sin(A) = b/sin(B) = c/sin(C)

In our case, since angle A is the vertex angle and side a is the base, we have:

a/sin(120) = b/sin(30)

Using the given length of the leg (side b) as 8 cm, we can solve for side a:

a/sin(120) = 8/sin(30)

a = (8 × sin(120)) / sin(30)

Using the values of sin(120) and sin(30) from a trigonometric table or calculator:

a ≈ (8 × √3) / (1/2) = 16√3 cm

Now, let's find the length of the diameter of the circumcircle. The circumcircle of a triangle passes through the vertices of the triangle and has its center at the intersection of the triangle's perpendicular bisectors.

Since the triangle is isosceles, the perpendicular bisector of the base will pass through the vertex angle and bisect it, resulting in two 60-degree angles.

In an equilateral triangle, the perpendicular bisector of a side passes through the triangle's center, which coincides with the center of the circumcircle. Since our isosceles triangle has two congruent sides, we can treat it as half of an equilateral triangle.

The length of the diameter of the circumcircle of an equilateral triangle is given by the formula:

Diameter = 2 × (side length) / √3

In our case, since we have half of an equilateral triangle, the diameter of the circumcircle will be:

Diameter = 2 × (16√3) / √3 = 32 cm

Therefore, the length of the diameter circumcised about this isosceles triangle is 32 cm.

Let's start solving the given problem. Suppose that an urn contains 3 different types of balls: red, green, and blue. Let pi denote the proportion of red balls, p2 denote the proportion of green balls, and p3 denote the proportion of blue balls.

Here Pi = 1.

Suppose also that 100 balls are selected with replacement, and there are exactly 38 red, 29 green and 33 blue.

We need to find the M.L.E. p; of p1, i = 1, 2, 3.

The probability of obtaining red ball from the urn = pi. The probability of obtaining green ball from the urn = p2. The probability of obtaining blue ball from the urn = p3

Given that, 100 balls are selected with replacement.

Let's calculate the probability of getting 38 red, 29 green, and 33 blue balls from the urn,

P(38 Red and 29 Green and 33 Blue) = P(Red)38 x P(Green)29 x P(Blue)33 = p₁³⁸ x p₂²⁹ x p₃³³

Therefore, the likelihood of obtaining the 38 red, 29 green, and 33 blue balls is L(p1,p2,p3) = p₁³⁸ x p₂²⁹ x p₃³³

Since, L(p1,p2,p3) is a continuous function, so we have to find the critical points of the function to obtain the minimum value of p₁. Let's take natural logarithm on both sides of the function, we get ln

L(p1,p2,p3) = 38 ln p₁ + 29 ln p₂ + 33 ln p₃.

So, taking partial differentiation with respect to p1, p2 and p3 and equating them to 0. We get the following equations,∂ ln L / ∂p1 = 38/p1 = 0∂ ln L / ∂p2 = 29/p2 = 0∂ ln L / ∂p3 = 33/p3 = 0On

solving the above three equations, we get p1 = 38/100 = 0.38p2 = 29/100 = 0.29p3 = 33/100 = 0.33

Therefore, P₁= 0.38, S= 0.29, P3 = 0.33. Hence, the required solution is P₁= 0.38, S= 0.29, P3 = 0.33.

dogs - 13

cats - 39

Step-by-step explanation:

Let the number of dogs Ma Bernier have be represented with d

She has 3 times as many cats as dogs, the number of cats she has :

cats = 3d

The sum of the cats and dogs is 52

d + 3d = 52

4d = 52

divide both sides of the equation by 4

d = 13

She has 13 dogs

Cats = 3d

Answer:

Step-by-step explanation:

Y Let f:R → R be defined by f(3) = Then x2 +1' a is (b) f is not a measurable function.

To determine if f is a measurable function, we need to check if the preimage of any measurable set in the codomain (R) is a measurable set in the domain (R).

In this case, the function f(3) = x^2 + 1 is defined only at x = 3. Since the domain R is continuous and f is only defined at a single point, the preimage of any set in the codomain will either be an empty set or a singleton set containing only the point x = 3.

For example, consider the set [f > 3] in the codomain R. The preimage of [f > 3] under f would be the set of all x in the domain R such that f(x) > 3. However, since f is only defined at x = 3, the preimage would be the singleton set {3}.  Since {3} is not a measurable set in the domain R, f is not a measurable function.

Therefore , the correct option is (B) f is not a measurable function.
