Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The total number of all these items is 19,607.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

There are seven houses, each containing seven cats.

Each cat kills seven mice.

Each mouse would have eaten seven ears of corn.

Each ear of corn would have produced seven sacks of grain.

Now, the total number of all these items is,

Total number of items

= Number of house + Number of cars + Number of mice + Number of ears of corns + Number of sack of grains

= 7 + 49 + 343 + 2401 + 16807

= 19,607

Hence, the total number of all these items is 19,607.

Jutin chooses a function J(x) = 3x - 1 that when he uses the number 7 as an input, then the output is 20.

As per the given data, Jutin chooses a function in which he uses the number 7 as an input, then the output is 20.

Here we have to determine which function Jutin has to use.

Now we have to substitute the value that x = 7 in all the given functions.

First function:

F(x) = 2\(x^{5}\)

F(7) = 2 \((7)^{5}\)

F(7) = 2 (16807)

F(7) = 33614 which is not equal to 20.

Second function:

G(x) = \(x^{2}\) - 19

F(7) = \((7)^{2}\) - 19

F(7) = 49 - 19

F(7) = 30 which is not equal to 20.

Third function:

H(x) = 13 - x

H(7) = 13 - 7

H(7) = 6 which is not equal to 20.

Fourth function:

J(x) = 3x - 1

J(7) = 3(7) - 1

J(7) = 21 - 1

J(7) = 20

The correct function is J(x) = 3x - 1

From figure A to figure B, the scale factors are 1/8 and 1/2. To scale shapes in various dimensions, utilize the scale factor.

A polygon is a closed object in a two-dimensional plane comprised of line segments rather than curves. The word "polygon" is a combination of the words "poly" (which meaning many) and "gon" (means sides). A closed figure must include a minimum of three line segments that connect end to end. A polygon is any three or more-sided closed two-dimensional shape. In addition to more complex designs like a dodecagon with twelve sides, polygons include triangles and squares. Polygons include shapes like quadrilaterals, triangles, hexagons, and pentagons. The number of sides the form has is indicated by the name.

Answer:

A. 6x+12x+90=180

Step-by-step explanation:

to find x they must all add up to 180 degrees

The average rate of change between year 1 and year 10 is given as follows:

4.3 thousand cars a year.

The average rate of change of a function is obtained by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

\(r = \frac{f(b) - f(a)}{b - a}\)

In this problem, the function is presented as follows:

C(x) = 0.15x³ - 3.28x² + 23.75x - 2.1.

The interval is:

[1,10], hence a = 1, b = 10.

At x = 1, the numeric value is found replacing each instance of x by 1, hence:

C(1) = 0.15(1)³ - 3.28(1)² + 23.75(1) - 2.1 = 18.52 thousand cars.

At x = 10, the numeric value is found replacing each instance of x by 10, hence:

C(10) = 0.15(10)³ - 3.28(10)² + 23.75(10) - 2.1 = 57.4 thousand cars.

Then the average rate of change is obtained as follows:

r = (57.4 - 18.52)/(10 - 1) = 4.3 thousand cars a year.

The problem is given by the image shown at the end of the answer.

A hypothesis can be differentiated from a theory because it is a specific prediction arising from the theory. The statement that is true is, a hypothesis can be differentiated from a theory because it is a specific prediction arising from the theory. A hypothesis is a suggested explanation of a phenomenon or observed data that is testable.

Hypotheses are more detailed, and are written to explain precisely what you think is going to occur in your research and the reason for that prediction. A hypothesis will be rejected if it does not fit the data, whereas a theory will be modified to fit the data.

A hypothesis is more like a forecast, and a theory is more like a law that explains how certain events operate. Thus, we can conclude that a hypothesis is a specific prediction arising from the theory.

The least possible value of n−m, expressed as a common fraction is 17/6.

By Triangle Inequality Theorem,

(x + 4) + 3x > x + 9

So 4x + 4 > x + 9

3x > 5

x > 5/3

If angle A is the largest angle, the side opposite to angle A will be the largest length, so

x + 9 > x + 4 (which is possible for all values of x)

and x + 9 > 3x

2x < 9

x < 9/2

Therefore 5/3 < x < 9/2. So m = 5/3 and n = 9/2

So calculating value of n - m

n - m = 9/2 - 5/3

= 27/6 - 10/6

= 17/6

Answer:

Step-by-step explanation:

The answer is option (C), that is, the events of rolling a fair die two times are independent. The events are neither disjoint nor exclusive.

When rolling a fair die two times, one can get any one of the 36 possible outcomes equally likely. Let A be the event of obtaining an even number on the first roll and let B be the event of getting a number greater than 3 on the second roll. Let’s see how the outcomes of A and B are related:

There are three even numbers on the die, i.e. A={2, 4, 6}. There are four numbers greater than 3 on the die, i.e. B={4, 5, 6}. So the intersection of A and B is the set {4, 6}, which is not empty. Thus, the events A and B are not disjoint. So option (A) is incorrect.

There is only one outcome that belongs to both A and B, i.e. the outcome of 6. Since there are 36 equally likely outcomes, the probability of the outcome 6 is 1/36. Now, if we know that the outcome of the first roll is an even number, does it affect the probability of getting a number greater than 3 on the second roll? Clearly not, since A∩B = {4, 6} and P(B|A) = P(A∩B)/P(A) = (2/36)/(18/36) = 1/9 = P(B). So the events A and B are independent. Thus, option (C) is correct. Neither option (A) nor option (C) can be correct, so we can eliminate options (D) and (E).

Answer:

27π Sq in.

Step-by-step explanation:

Circle A is equal to 9π sq inches. (Radius squared times Pi), Segment BC is a radii of Circle B and the diameter of Circle A. Meaning Circle B's radius is 6 inches. The area of circle B would be 36π sq inches. Now we subtract Circle A's area from Circle B's area(36π sq in. - 9π sq in.), the area of the shaded region is 27π sq in.

If Rachana randomly selects two mugs from the set, the probability that she gets two different mugs is 0.1556 or 15.56%.

To solve this problem, we can use the concept of combinations. Since there are 10 mugs in the set, there are 10 choose 2 = 45 ways to select two mugs without considering order.

Out of these 45 ways, we need to count the number of ways Rachana can select two different mugs. Since there are 3 different types of mugs, Rachana can choose any one of the three types for the first mug. There are 10 mugs in the set, out of which 3 belong to the chosen type. Therefore, the probability of choosing a mug of the chosen type is 3/10.

For the second mug, Rachana can choose from the remaining 9 mugs. Since she needs to choose a different type of mug, she can choose any one of the 2 remaining types. There are 7 mugs left from the other 2 types. Therefore, the probability of choosing a mug of a different type is (7/9) * 2/3 = 14/27.

Therefore, the probability of selecting two different mugs is the product of the probabilities of selecting a mug of the chosen type and a mug of a different type. This is given by (3/10) * (14/27) = 7/45, which is approximately 0.1556 or 15.56%.

The identity sin θ sec θ = tan θ is true for all values of θ except for the values where cos θ = 0.

To verify the identity sin θ sec θ = tan θ, we need to simplify the left-hand side (LHS) and the right-hand side (RHS) and show that they are equal.

LHS = sin θ sec θ

= sin θ (1/cos θ)

= sin θ/cos θ

= tan θ

RHS = tan θ

Since LHS = RHS, we can conclude that the identity sin θ sec θ = tan θ holds true.

The domain of validity for this identity is all real numbers θ except for the values where cos θ = 0. At those values, the expression sec θ is undefined.

The identity sin θ sec θ = tan θ is verified to be true for all values of θ except for the values where cos θ = 0.

         = \(\frac{7}{14}\)

         = \(\frac{1}{2}\)

         = 0.5

cos(D) = \(\frac{\text{Adjacent side}}{\text{Hypotenuse}}\)

We need 12 tiles to cover the floor.

What is the fraction?

A fraction is a mathematical representation of a part of a whole, where the whole is divided into equal parts. A fraction consists of two numbers, one written above the other and separated by a horizontal line, which is called the fraction bar or the vinculum.

To cover the floor, we need to find how many tiles of side 3 m can fit into the length and width of the floor.

The number of tiles that can fit along the length of the floor is:

10 m / 3 m = 3.33

Since we can't use a fraction of a tile, we round up to 4 tiles.

Similarly, the number of tiles that can fit along the width of the floor is:

9 m / 3 m = 3

So, we need 4 tiles along the length and 3 tiles along the width.

The total number of tiles needed to cover the floor is:

4 tiles x 3 tiles = 12 tiles.

Therefore, we need 12 tiles to cover the floor.
