A 2-column table with 10 rows. the first column is labeled x with entries 0.5, 1, 1, 1.5, 2, 2, 2.5, 3.5, 3.5, 4. the second column is labeled y with entries 1, 1, 2, 3, 2, 5, 4, 5, 6, 7. a graph shows the horizontal axis numbered 1 to 4 and the vertical axis numbered 1 to 7. a line increases from 0 to 4. the regression calculator shows the relationship between the hours devin spent playing a video game, x, and the levels he achieved, y. which number of hours can be used to make an extrapolation of the level he could achieve? 2 3 4 5
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.
What is a regression line?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.
How to determine number of hours?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.
0.39999 ≤ y ≤ 7.6.
Therefore, two (2) number of hours can be used to make an extrapolation of the level he could achieve.

Maria got a prepaid debit card with $20 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 8 cents per yard. If after that purchase there was $19.12 left on the card, how many yards of ribbon did Maria buy?
Answer:
11 yards
Step-by-step explanation:
Given :
Maria got a prepaid debit card with $20 on it.
For her first purchase with the card,
she bought some bulk ribbon at a craft store.
The price of the ribbon was 8 cents per yard.
To Find:
If after that purchase there was $19.12 left on the card, how many yards of ribbon did Maria buy?
Solution:
$20- 19.12= 0.88
She spent 0.88 on the ribbon
One yard of ribbon is $0.08
0.88/0.08 = 11
Therefore she bought 11 yards of ribbon

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

In this problem you will compare the effects of different compounding periods on the interest an investment earns. Complete the table below using the values indicated. Show the formula you used, with the correct values, in the second column. In the third column, give the result, rounded to the nearest cent.
Principal: $1,000
APR: 4.5%
Time: 10 years
Find the equations for annually, quarterly, monthly and daily
Answer:
see attached
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 ...
annually: n = 1quarterly: n = 4monthly: n = 12daily: n = 365The formula you will evaluate uses these values where 'n' is in the formula. Corresponding account balances are ...
annual compounding: $1552.97quarterly compounding: $1564.38monthly compounding: $1566.99daily compounding: 1568.27__
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.
2. For a simple interest rate of 10%, p.a calculate the number of year's needed for an interest of $1149.60 to be earned on an investment of $2874
Answer:
r=10%
I=1149.60
P=2874
t=(I×100)/(p×r)
(1149.60×100)/(2874×10)
114960÷28740
4 years
[tex]r = 10\%[/tex]
[tex]p = 2874[/tex]
[tex]l = 1149.60[/tex]
to find:the numbers of year's needed for the investment.
solution:[tex]t = \frac{l \times 100}{p \times r} [/tex]
[tex]t = \frac{1149.60 \times 100}{2874 \times 10} [/tex]
[tex]t = \frac{114960}{28740} [/tex]
[tex]t = 4[/tex]
therefore, 4 years is needed for the investment.

Solve for m (4m-5) (3m+3)
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

why do we need math and history
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.
What is the importance of math in real life?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:
History may teach us important lessons that will help us in the future. We may learn how to prevent or repeat prior errors and accomplishments by looking at what went right and wrong in the past.Understanding the current: History enables us to understand how current events continue to be shaped by earlier ones and how they have impacted our world.Understanding diverse civilizations: History offers a glimpse into many cultures and communities.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.

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!
