The decimal division of 18.92 by 11 gives us; 1.72

When dividing decimals,  we first have to convert the divisor to a whole number by moving the decimal point to the right. Thereafter, we now carry the dividend's decimal point up to the exact same number of places to the right and then divide the resultant numbers in the normal way, like in regular long division.

We want to divide 18.92 by 11. Thus, let us apply that rule described above to get;

18.92/11 = 1892/1100

= 1 + (1892 - 1100)/1100

= 1 + (792/1100)

= 1 + 0.72

= 1.72

Answer:

Step-by-step explanation:

insert f(-12) for f(x) and solve

f(-12)=|-12+7|

add -12 and 7

f(-12)=|-5|

absolute value makes it positive

f(-12)=5

If f(x)=|x+7|, the value of f(-12)=5

Given :

the function f(x)=|x+7|. Lets find out f(-12)

f(x) is an absolute function . Absolute function always gives us positive value .

for example |-6|=6

In f(-12) the value of x is -12

To find f(-12) we replace x  with -12 in f(x).

\(f(x)=|x+7|\\f(-12)=|-12+7|\\f(-12)=|-5|\\f(-12)=5\)

so,  we got f(-12)=5

The answer is 5

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%.

Regarding cross-sectional data sets, the following statements are true:

1. These data require attention to the frequency at which they are collected (weekly, monthly, yearly, etc.): This statement is true. Cross-sectional data sets are collected at a specific point in time or over a specific period, and the frequency of data collection is important for understanding the temporal context.

2. It can be assumed that the data were obtained through a random sampling of the underlying population: This statement is not necessarily true. While random sampling is desirable in statistical analysis, it cannot be assumed for cross-sectional data sets. The sampling method depends on the specific study design and data collection process.

3. The data are collected multiple times over several different time periods: This statement is not true. Cross-sectional data sets are collected at a single point in time or over a specific period, but they do not involve multiple data collection instances over different time periods.

4. Most observations are not independent across time: This statement is not true. Cross-sectional data sets focus on a specific time point or period, and therefore, the observations within the data set are typically independent and do not involve tracking changes over time.

The length of the base of the triangular base is 4 feet.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The formula for the volume of a triangular prism is:

V = (1/2)bh x h

where b is the base of the triangular base, h is the height of the triangular base, and h is the height of the prism.

Substituting the given values, we get:

72 = (1/2)(x) x 3 x 12

Simplifying, we get:

72 = 18x

Dividing both sides by 18, we get:

x = 4

Answer:

The length, x, of the base of the triangular base of the prism is 4 ft.

Step-by-step explanation:

The volume of a regular prism can be found by multiplying the area of its base by its height.

\(\boxed{\textsf{Volume of a regular prism}=\textsf{Base area} \times\textsf{height}}\)

The base of a triangular prism is a triangle.

The area of a triangle is half the product of its base and height.

Given that b = x and h = 3, the area of the triangular base of the prism is:

\(\begin{aligned}\textsf{Area of triangular base}&=\dfrac{1}{2} bh\\\\&=\dfrac{1}{2} \cdot x \cdot 3\\\\&=\dfrac{3}{2}x\; \sf ft^2\end{aligned}\)

To find the value of x, substitute the given volume, v = 72 ft³, the given height, h = 12 ft, and the found area of the base into the formula for volume, and solve for x:

\(\begin{aligned}\textsf{Volume}&=\textsf{Base area} \cdot \textsf{Length}\\\\\implies 72&=\dfrac{3}{2}x \cdot 12\\\\72&=\dfrac{36}{2}x \\\\2 \cdot 72&=2 \cdot \dfrac{36}{2}x \\\\144&=36x\\\\\dfrac{144}{36}&=\dfrac{36x}{36}\\\\4&=x\end{aligned}\)

Therefore, the value of x is 4 feet.

The triangles with side lengths 8, 10, 12 and 14, 18, 21 are not similar.

In order for two triangles to be similar, their corresponding sides must have proportional lengths. We can compare the ratios of corresponding sides to determine if the triangles are similar.

For the first triangle with side lengths 8, 10, 12, we can calculate the ratios as follows:

- Ratio of the lengths of the first and second sides: 8/10 = 4/5

- Ratio of the lengths of the first and third sides: 8/12 = 2/3

- Ratio of the lengths of the second and third sides: 10/12 = 5/6

For the second triangle with side lengths 14, 18, 21, the ratios are:

- Ratio of the lengths of the first and second sides: 14/18 = 7/9

- Ratio of the lengths of the first and third sides: 14/21 = 2/3

- Ratio of the lengths of the second and third sides: 18/21 = 6/7

Since the ratios of corresponding sides in the two triangles are not equal, the triangles are not similar. The ratios of side lengths must be the same for all corresponding sides in order for two triangles to be similar.

Answer: A. \(3\sqrt{5}\)

B. l=\(6\sqrt{5}\), w=\(3\sqrt{5}\)

Step-by-step explanation:

A. A=l*w

l=2w

A=2w*w

90=2w*w

w*w=45

w=\(\sqrt{45}\)

w=\(\sqrt{9*5}\)

w=\(3\sqrt{5}\) ==> Square length and the rectangle width

B. 90=l*w

90=l*\(3\sqrt{5}\)

30=l\(\sqrt{5}\)

l=\(\frac{30}{\sqrt{5} }\)

l=\(\frac{30\sqrt{5} }{5}\)

l=\(6\sqrt{5}\), w=\(3\sqrt{5}\)

What is the Mean, Mode and Median?

Mean: The mean is the average of a set of numbers, calculated by adding up all the numbers and dividing by the total number of numbers in the set.

Mode: The mode is the most frequently occurring number in a set of numbers.

Median: The median is the middle value in a set of numbers when the set is sorted in ascending or descending order.

a) Mode: The mode of the list is 7, as it is the number that occurs most frequently (3 times).

The height of the 10th bounce of the ball will be 0.6 feet.

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.

The nth term of the geometric sequence is given by

\(\sf T_n=ar^{n-1}\)

Where,

According to the given question.

During the first bounce, height of the ball from the ground, a = 4.5 feet

And, the each successive bounce is 73% of the previous bounce's height.

So,

During the second bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 10\)

\(=\dfrac{73}{100}(10)\)

\(\sf = 0.73 \times 10\)

\(\sf = 7.3 \ feet\)

During the third bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 7.3\)

\(=\dfrac{73}{100}(7.3)\)

\(\sf = 5.33 \ feet\)

Like this we will obtain a geometric sequence 7.3, 5.33, 3.11, 2.23,...

And the common ratio of the geometric sequence is 0.73

Therefore,

The sixth term of the geometric sequence is given by

\(\sf T_{10}=10(0.73)^{10-1\)

\(\sf T_{10}=10(0.73)^{9\)

\(\sf T_{10}=10(0.059)\)

\(\sf T_{10}=0.59\thickapprox0.6 \ feet\)

Hence, the height of the 10th bounce of the ball will be 0.6 feet.
