Answer:

-9/11

Step-by-step explanation:

You have to find the reciprocal of the number you're dividing by. In your case the number you are dividing by is 11/6. Just flip 11/6 to get the reciprocal, and the multiply it by -3/2. 6/11 is the reciprocal of 11/6.

\(-\frac{3}{2} * \frac{6}{11} = -\frac{18}{22}\)

Simplify by dividing by 2.

-9/11 is the answer.

Step-by-step explanation: : Explanation We have height (H) = 4 yards Diameter = 4x4 = 16, Radius (r) = 16/2 = 8, volume and cylinder V = nr2h. V= 3.14 x 8x8x4, V= 804.25 yards 3

Answer:

\( - 2m - 5m = 9m - 12 \\ ⟶ - 2m - 5m - 9m = - 12 \\ ⟶ - 16m = - 12 \\ ⟶ - m = \frac{ - 12}{16} \\ ⟶ - m = \frac{ - 6}{8} \\ ⟶ m = - ( - \frac{6}{8} ) \\ ⟶m = \frac{6}{8} \)

\(m=0.75\)

Answer:

\( \boxed{ \bold{ \huge{ \boxed{ \sf{m = 0.75}}}}}\)

Step-by-step explanation:

\( \sf{ - 2m - 5m = 9m - 12}\)

Collect like terms

⇒\( \sf{ - 7m = 9m - 12}\)

Move 9m to left hand side and change it's sign

⇒\( \sf{ - 7m - 9m = - 12}\)

Collect like terms

⇒\( \sf{ - 16m = - 12}\)

Divide both sides of the equation by -16

⇒\( \sf{ \frac{ - 16m}{ - 16} = \frac{ - 12}{ - 16} }\)

Calculate

⇒\( \sf{ m = 0.75}\)

Answer:

Third term is 36

Step-by-step explanation:

According to the definition of proportion, if two sets of given numbers are  in the same ratio, then the ratios are said to be directly proportional to each other

We use the symbol :: to denote proportion

So if

a:b :: c:d

Then a/b = c/d

We are given that first number = 16, second is 24 and the last is 54

Let the third number be x

We have that
16:24 :: x : 54

In other words

16/24 = x/ 54

Simplifying left side

2/3 = x/54

x = 2/3 x 54 = 36

If regular hexagon, regular octagon are inscribed in circle, perimeter of hexagon is greater than perimeter of octagon, each perimeter is greater than circumference of circle. Therefore, statement B is true.

The perimeter of a polygon is the sum of the lengths of all its sides. In a regular polygon, all sides have equal length, so the perimeter is simply the number of sides multiplied by the length of one side. The circumference of a circle is the distance around its outer edge.

Since both polygons are inscribed in the same circle, they have the same circumcircle, which means that their perimeters are both less than the circumference of the circle.

To compare the perimeters of the two polygons, we need to know the number of sides of each polygon and the length of one side. A regular hexagon has six sides, and a regular octagon has eight sides. Since the circle is inscribed in both polygons, the sides of each polygon are tangents to the circle, forming right angles with the radii of the circle.

Thus, we can draw a right triangle with the radius of the circle as the hypotenuse, and the side of the hexagon (or octagon) as one leg. Using trigonometry, we can find the length of one side of the hexagon (or octagon) in terms of the radius of the circle.

After calculating the lengths of one side of each polygon, we can compare their perimeters. It turns out that the perimeter of the octagon is greater than the perimeter of the hexagon, since the octagon has more sides.

Therefore, statement B is true.

Given data

\((1-2b)(1-5b+b^{2} )+(2b-1)(1-6b+b^{2} )=b(1-2b)\)

breaking the expansion into 2 we have

\(=(1-2b)(1-5b+b^{2} )\)

\(=(1)(1)+(1)(-5b)+(1)(b^2)+(-2b)(1)+(-2b)(-5b)+(-2b)(b^2)\)

\(=1-5b+b^2-2b+10b^2-2b^3\)

\(=-2b^3+11b^2-7b+1\)

expanding this \((2b-1)(1-6b+b^2)\) gives:

\(=2b^3-13b^2+8b-1\)

adding both equation gives

\(= -2b^3+11b^2-7b+1 + 2b^3-13b^2+8b-1\)

\(= -2b^2 + b\)

\(= b - 2b^2\)

\(= b (1 - 2b)\)

Answer:

$1850

Step-by-step explanation:

The annual cost of Martinez's family membership for medical insurance is $3,900.

The company pays 50% of the cost.

So, the cost paid by the company= 50% of $3,900.

\(=\frac {50}{100}\times 3900=\$1850\)

The remaining cost for the family medical insurance must be paid by Gail Martinez.

So, the annual payment by her =$3900-$1850=$1850

Hence, she pays $1850  annually for medical insurance.

The volume of the right prism include the following: 8,640 in³.

In Mathematics and Geometry, the volume of a rectangular prism can be calculated by using the following formula:

Volume of a rectangular prism = L × W × H

Where:

Next, we would determine the area of the triangle at the base of the right prism as follows:

Base area = 1/2 × ( 36 × 12)

Base area = 1/2 × 432

Base area = 216 in².

Now, we can calculate the the volume of this right prism:

Volume = base area × height

Volume = 216 × 40

Volume = 8,640 in³.

The mean absolute deviation of the data set 10, 8, 10, 6, 6, 2, 10, 4 is 2.5.  

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.

We have data:

10, 8, 10, 6, 6, 2, 10, 4

We know the mean absolute deviation formula:

\(\rm MAD = \dfrac{\sum (x_i-X)}{n}\)

X is the mean:

X = (10+8+10+6+6+2+10+4)/9

X = 56/8 = 7

MAD = 20/8 = 2.5

Thus, the mean absolute deviation of the data set 10, 8, 10, 6, 6, 2, 10, 4 is 2.5.

The relationship that is NOT always true is B. (A U B U C) = Ac - Bc + (A U B) + (A ∩ B)c - (B U C) + (A ∩ B ∩ C).

The correct expression for the union of three events A, B, and C is given by the principle of inclusion-exclusion, which is stated in option A. This principle accounts for the overlapping regions between the events to avoid double counting. Option B is incorrect because it does not follow the principle of inclusion-exclusion.

In option B, the term (A U B) is correctly included to account for the union of A and B. However, the term (A ∩ B)c is subtracted, which results in the exclusion of the intersection of A and B. This is not consistent with the principle of inclusion-exclusion, which includes the intersection term.

To further illustrate the error in option B, consider the case where A, B, and C are mutually exclusive events (i.e., they have no intersection). In this case, the expression (A U B U C) = Ac - Bc + (A U B) + (A ∩ B)c - (B U C) + (A ∩ B ∩ C) simplifies to A U B U C = Ac - Bc + (A U B) - (B U C) + (A ∩ B ∩ C). However, this contradicts the definition of mutually exclusive events, as the union of A, B, and C should be equal to A U B U C = A + B + C.

Therefore, option B is not always true and does not accurately represent the relationship between the union of three events A, B, and C.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

If the magnitude of the second derivative, |f''|, is small on a given 6-interval centered at a, then the slopes of the tangent lines change slowly as r increases over the interval.

The second derivative, f'', measures the rate of change of the slope of a function f. If |f''| is small, it implies that the rate of change of the slope is small. In other words, the function is relatively "smooth" or "flat" on the interval.

When the function is smooth, the tangent lines to the curve change slowly as the parameter r increases. This means that for small changes in r, the slopes of the tangent lines will not vary significantly. The graph of the function will exhibit a gradual change, without sudden or rapid fluctuations in the steepness of the curve.

Conversely, if |f''| were large on the 6-interval, it would indicate that the function has more pronounced changes in slope. In such cases, the tangent lines would change quickly as r increases, resulting in a graph with more abrupt variations in steepness.

Therefore, when the magnitude of the second derivative is small on a given 6-interval with center a, the slopes of the tangent lines change slowly as r increases over the interval.
