Answer:

P(dog) = 12/30 = 0.4 or 40%

Step-by-step explanation:

We can use the formula for probability:

P(dog) = number of students with a dog / total number of students

To find the number of students with a dog, we can use the fact that 19 students have a dog and 6 students have neither a cat nor a dog:

number of students with a dog = total number of students - number of students with no pets - number of students with only a cat

number of students with a dog = 30 - 6 - 12 = 12

So the probability that a student chosen randomly from the class has a dog is:

P(dog) = 12/30 = 0.4 or 40%

The value of x in the circle is,

⇒ x = 25.6

We have to given that;

An angle is, 23 degree

Hence, We can formulate;

(14x - 22) + 23 = 360

14x + 1 = 360

14x = 359

x = 25.6

Thus, The value of x in the circle is,

Answer:

  85 1/3 cubic units

Step-by-step explanation:

You want the volume of a solid whose base is the ellipse in the x-y plane with axes 16 and 8 units and whose cross sections perpendicular to the major axis are isosceles triangles with height equal to 1/4 of the cross section dimension parallel to the minor axis.

The isosceles triangle cross section has base 2y and height (2y)/4, so area of ...

  A = 1/2bh

  A = (1/2)(2y)(2y/4) = y²/2

A differential of volume is the product of the area of a slice and its thickness:

  dV = A·dx = (1/2)y²·dx

The total volume is the integral of this differential of volume over the interval x ∈ [-8, 8]. That integral will be twice the integral on the interval [0, 8}, so we have ...

  [tex]\displaystyle V=2\int_0^8{\dfrac{y^2}{2}}\,dx=16\int_0^8{\left(1-\dfrac{x^2}{64}\right)}\,dx=16\left((8-0)-\dfrac{8^3-0^3}{3\cdot64}\right)\\\\\boxed{V=85\dfrac{1}{3}\text{ cubic units}}[/tex]

__

Alternate computation

The volume of half an ellipsoid with semi-axes 2, 4, and 8 is ...

  V = (1/2)(4/3)π(abc)

  V = (1/2)(4/3)π(2)(4)(8) = 128π/3

The area of half an ellipse with semi-axes 2 and 4 is ...

  A = (1/2)π(ab)

  A = (1/2)π(2)(4) = 4π

The area of a triangle with the same semi-axes is ...

  A = 1/2bh = (1/2)(2)(2·4) = 8

Then the ratio of triangle area to ellipse area at each cross section is ...

  triangle / ellipse = 8/(4π) = 2/π

The volume of the solid of interest is estimated to be this factor multiplied by the volume of the half-ellipsoid:

  (2/π)(128π/3) = 256/3 = 85 1/3 . . . . same as above

The patient will have to pay approximately $727.74 in total.

Total grams of marijuana: 39 grams

Weight of each bud: 0.07 grams

Number of buds = Total grams of marijuana / Weight of each bud

Number of buds = 39 / 0.07 ≈ 557.14

Since the patient can't purchase a fraction of a bud, they will need 558 buds (rounding up).

Now, let's calculate the total cost.

Dispensary cost: $530 per ounce (28.4 grams)

First, we need to find the cost per gram:

Cost per gram = $530 / 28.4 ≈ $18.66

Total grams of marijuana: 39 grams

Total cost = Cost per gram * Total grams of marijuana

Total cost = $18.66 * 39 ≈ $727.74

The patient will have to pay approximately $727.74 in total.

The reduced row echelon form of the matrix is given as follows:

[tex]\left[\begin{array}{cccc}-1&0&0&8\\0&1&0&-2\\0&0&1&-6\end{array}\right][/tex]

The reduced row echelon form of a matrix is matrix in which the matrix except the last column has the format of an identity matrix, that is, a matrix in which the principal diagonal elements are of 1 and the rest of the elements are of 0.

Hence we can use a mix of row operations, along with the solution of a system of equations, to obtain the reduced row echelon form of a matrix.

The matrix in the context of this problem is defined as follows:

[tex]\left[\begin{array}{cccc}-1&5&-3&6\\0&3&6&-42\\0&-6&-1&18\end{array}\right][/tex]

First we want a value of 1 at line 1, column 1, hence we multiply the first line by -1, that is:

R1 -> -R1.

Hence:

[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&3&6&-42\\0&-6&-1&18\end{array}\right][/tex]

Then we want a value of 1 at line 2 column 2, thus:

R2 -> R2/3.

Hence:

[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&1&2&-14\\0&-6&-1&18\end{array}\right][/tex]

Then we want a value of 0 at line 3, column 2, hence:

L3 -> L3 + 6L2

[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&1&2&-14\\0&0&11&-66\end{array}\right][/tex]

Then the solution to the system of equations is given as follows:

Hence the row echelon form of the matrix is given as follows:

The family's monthly payment should be $504.70.

We can use the following formula:

[tex]P = (r * A) / (1 - (1 + r)^(-n))[/tex]

where

In this instance, the total loan amount is $43,008, the total number of payments is 9 years * 12 months/year = 108 months . The yearly interest rate must first be divided by 12 to determine the monthly interest rate. Assume that there is a 5% yearly interest rate.

[tex]r = 0.05 / 12 = 0.00417[/tex]

Now we can substitute the values into the formula and solve for P:

[tex]P = (0.00417 * $43,008) / (1 - (1 + 0.00417)^(-108))[/tex]

= $504.70

The cost each of one of the bag of windflower bulbs and one package of crocus bulbs is $14 and $16 respectively.

Let

cost each of one of the bag of windflower bulbs = x

Cost of each one package of crocus bulbs = y

4x + 9y = 200

2x + 6y = 124

Multiply (2) by 2

4x + 12y = 148

So,

4x + 9y = 200

4x + 12y = 248

Subtract to eliminate x

12y - 9y = 248 - 200

3y = 48

divide both sides by 3

y = 48/3

y = 16

Substitute y = 16 into (1)

4x + 9y = 200

4x + 9(16) = 200

4x + 144 = 200

4x = 200 - 144

4x = 56

x = 56/4

2. Spending variances: Analyze the costs related to pizza production and delivery person wages. Compare the actual costs to the budgeted costs, and label the variances as "F" for favorable (actual costs lower than budgeted) or "U" for unfavorable (actual costs higher than budgeted).

3. Activity variances: Assess the differences in the number of pizzas sold and deliveries made compared to the budgeted activity levels. Label these variances as "F" for favorable (higher activity than budgeted), "U" for unfavorable (lower activity than budgeted), or "None" for no effect (zero variance).

The correct answer is B. Wages will increase.

When the Long-Run Aggregate Supply (LRAS) curve begins to slope upward in the second phase, it indicates that as the economy moves towards full employment and productive capacity, wages will increase.

The upward slope of the LRAS curve suggests that as the economy expands and approaches its maximum potential output, the demand for labor increases, leading to higher wages.

This is because firms need to pay higher wages to attract and retain workers in a tightening labor market, where the supply of labor becomes relatively scarce compared to the demand.
