Answer: Math and history are very important!

Step-by-step explanation: We use math every day, some people more than others. Math helps your brain become more smarter. It gives us a way to understand different types of patterns better, to quantify relationships, and to in some cases, predict the future. There are many reasons that math is important to us, but what about history? History gives us a tool  to help us better understand our past, helping us to spot patterns that are invisible in the present. We can learn about past societies, past ideologies, and lots of other things to see how we got to where we are now. Studying math and history might be boring, pointless, or hard right now(I struggle with math!), but these two subjects are used in everyday life!

There are a number of reasons why studying history and mathematics is crucial. Although history aids in the knowledge of the past, the development of critical thinking abilities, and the development of cultural understanding, mathematics gives a framework for comprehending the world around us and develops essential skills.

A person who is proficient in maths can manage a budget, construct furniture, predict, and tell time, among other essential life abilities. As an adult, you need to be able to analyse expenditures, balance a chequebook, and deduct balances. Math can help you with these tasks. Math helps you become a better cook.

Several everyday uses of mathematics exist in contemporary life. It offers a common vocabulary for speaking about and comprehending the physical world. Engineering, computer science, physics, finance, and many other professions depend heavily on mathematics. Many of the technical advancements we take for granted today, like cell phones and space travel, would not exist without mathematics.

On the other hand, history is the study of historical occurrences and their importance. It is significant for a variety of reasons, such as:

Therefore, both mathematics and history are significant academic disciplines for a variety of reasons. Although history enables us to comprehend the past, learn from it, and foster cross-cultural understanding, mathematics gives us a framework for understanding the world around us and develops crucial abilities.

Step-by-step explanation:

You are asked to use the compound interest formula for different values of n, the number of times per year the interest is compounded.

__

The basic formula is ...

  A = P(1 +r/n)^(nt)

for the amount in an account in which principal P earns interest at annual rate r compounded n times per year for t years.

The problem statement gives values for P, r, t, so we only need to compute the result for different values of n. With the given values filled in, the formula is ...

  A = 1000(1 +0.045/n)^(10n)

Values of n to be used are ...

The formula you will evaluate uses these values where 'n' is in the formula. Corresponding account balances are ...

__

For repetitive evaluation of the same formula, we like a calculator or spreadsheet. Many calculators have the "time value of money" formulas pre-programmed. This is shown in the second attachment, where the value that varies is "C/Y", the number of compoundings per year.

Answer: Given that MP \\NS , RS\\PQ and MR =NQ

MRN is a straight line with sum of angles equal to 180⁰ MQN is also a straight line triangle equal to 180⁰

Angle at R + 3 = Angle at Q +2 = 180⁰

Angle R is alternate to Q and angle 2 is alternate to 3 and both sets are equal

Therefore angle 1 is equal to 4 and this makes their third angles in the triangle equal.

Triangle MQP then becomes a perfect replica of NRS

Answer:

m= 26

Step-by-step explanation:

The sum of the angles that lie on a straight line is 180°.

(4m -5)° +(3m +3)°= 180° (adj. ∠s on a str. line)

4m +3m -5 +3= 180

7m -2= 180

7m= 180 +2

7m= 182

Divide both sides by 7:

m= 182 ÷7

m= 26

Answer:

part: 17 players = 1/4

whole: 68 players in all

percent: 17 players = 25%

Step-by-step explanation:

We'll use p as a variable for the total players, alright?

So, 25% of p usually gets called back.

This season, 17 is 25% of p OR you might say 17 = 1/4 of p

in other words, p/4 = 17

multiply each side by 4 (to get the variable alone)

p = 17 * 4

p = 68

______________

part/whole = percent/100

SUBSTITUTE!

17/68 = 25%

check!

(simplify) 1/4 = 25% true!

The data of players of volleyball tournament, the mean is 56.5, median is 53, range is 56 and interquartile range is 20

The mean of the data is the average value of the given data. The mean of the data is the ratio of the sum of all the values of data to the total number of values of data.

The median of the data is the middle value of the data set when it arrange in ascending or descending order.

Mode of a data set is the value, which occurs most times for that data set. The value which has the highest frequency in the given set of data is known as the mode of that data set.

The stem-and-leaf plot shows the number of digs for the top 15 players at a volleyball tournament. The table is attached below.

The data according to the table is,

41,41,43,43,45,50,52,53,54,62,63,63,67,75,97

[tex]\mu=\dfrac{41+41+43+43+45+50+52+53+54+62+63+63+67+75+97}{15}\\\mu=\dfrac{849}{15}\\\mu=56.5[/tex]

The arranged data according to the table is,

41,41,43,43,45,50,52,53,54,62,63,63,67,75,97

Here, the middle value is 53. Thus, the median is 53.

Mode is the data which occur most offen. Here the order of modes from least to greatest is,

41   41   43   43   45   50   52   53   54   62   63   63   67   75   97  

Lowest value in data is 41 and highest is 97. Thus, the range is,

[tex]r=97-41\\r=56[/tex]

The third quartile of data is 63 while first quartile is 43. Thus, the interquartile range is.

[tex]IQR=63-23\\IQR=20[/tex]

Thus, the data of players of volleyball tournament, the mean is 56.5, median is 53, range is 56 and interquartile range is 20.

Based on the graph of this regression calculator, the number of hours that can be used to make an extrapolation of the level he could achieve is: A. 2.

A regression line can be defined as a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.

From the graph of this regression calculator, we can deduce that the linear regression is given by this function y ≈ 1.62x + 0.117; r ≈ 0.92.

Thus, the extrapolation would be given by:

0.14999 ≤ x ≤ 4.35.
