Answer:
Population
Step-by-step explanation:
In mathematics, when we talk about the people, places, or things under consideration, we are referring to the population. The Population is the entire sum of objects in a study. When a researcher wants to study factors that concern a particular set of people, places, or things, the group under study is the population. For example, the researcher might want to do a study on the amount of food consumed by Brazilian students in the year 2019. The Brazilian students represent the population, because they are the group of people being studied.
The population under study might sometimes be difficult to study as a whole. For example, the study of the entire Brazilian students might be cumbersome. In such cases, a sample can be drawn from the population and studied, or the population narrowed down a little more, so that it can be easily studied.

Answer:
Hi there!
The distance L between two points (x1, y1) and (x2, y2) in two-dimensional plane could be calculated by:
L = sqrt((y2 - y1)^2 + (x2 - x1)^2)
The distance between two points (-5, 4) and (3, -2) can therefore be calculated by:
L = sqrt( (-2 - 4)^2 + (3 - -5)^2) = sqrt( 6^2 + 8^2) = sqrt(36 + 64) = sqrt(100 ) = 10
=> Option C is correct.

What is the sum of this arithmetic series?
586 +564 + 542 + ... +212
Answer:
sum of the series = 7182
Step-by-step explanation:
This is an arithmetic series. The first term is known as 586 and the last term is known as 212. We are ask to find the sum of the series. The common difference of this sequence is -22 . The difference between the next term and the previous term is -22. Let us find the number of terms.
common difference = 564 - 586 = -22
number of terms = n
nth term = a + (n - 1)d
212 = 586 + (n - 1)-22
212 = 586 - 22n + 22
212 - 586 - 22 = -22n
-396 = -22n
divide both sides by -22
n = -396/-22
n = 18
Using the formula for sum
sum of nth term = n/2(a + l)
where
l = last term
a = first term
n = number of term
sum of nth term = n/2(a + l)
sum of nth term = 18/2(586 + 212)
sum of nth term = 9(798 )
sum of the series = 7182

Consider the polynomials p1(t) = 1 + t , p2(t) = 1 -t , and p3(t) = 2 (for all t). By inspection, write a linear dependence relation among p1, p2, and p3. Then find a basis for Span{ p1 , p2 , p3 }.
Answer:
[tex]\{p_1,p_2\}$ is a basis of Span\{p_1,p_2,p_3\}[/tex]
Step-by-step explanation:
Given the polynomials:
[tex]p_1(t) = 1 + t\\ p_2(t) = 1 -t\\p_3(t) = 2\\[/tex]
On Inspection
[tex](1+t)+(1-t)=1+1+t-t=2\\$Therefore:\\p_1(t)+p_2(t)=p_3(t)[/tex]
By the Spanning Theorem
If one vector in S is a linear combination of the others, we can delete it and get a subset (one vector smaller) [tex]S' \subseteq S[/tex] that has the same span.
Therefore, since [tex]p_3(t)=p_1(t)+p_2(t)[/tex]
[tex]Span\{p_1,p_2,p_3\}=Span\{p_1,p_2\}[/tex]
[tex]p_1$ and p_2[/tex] are linearly independent because [tex]p_1[/tex] cannot be written in terms of [tex]p_2[/tex].
Therefore, [tex]\{p_1,p_2\}$ is a basis of Span\{p_1,p_2,p_3\}$ as required.[/tex]
A linear dependence relation among the polynomials p₁, p₂, and p₃ is given as p₁ + p₂ = p₃
What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Consider the polynomials are
[tex]\rm p_1(t) = 1 + t\\\\ p_2(t) = 1 -t \\\\ p_3(t) = 2[/tex]
a linear dependence relation among p₁, p₂, and p₃ will be
Let add the p₁ and p₂, we have
1 + t + 1 -t = 2
We get the polynomial p₃.
Thus the linear relation is p₁ + p₂ = p₃

There are 10 clean individual socks in your sock drawer. There is only one matching pair among them. In the dark, you reach into the drawer and randomly pick 2 socks. What is the probability that you choose the matching pair
The required probability of choosing the matching pair of socks is approximately 0.0222 or 2.22%.
To find the probability of choosing the matching pair of socks, we need to consider the total number of possible outcomes and the number of favorable outcomes.
In this case, there are 10 individual socks in the drawer, and only one matching pair. When you randomly pick 2 socks, there are C(10, 2) = 45 possible outcomes, as you are choosing 2 socks out of 10.
The favorable outcome is when you choose the matching pair, which can occur in only one way.
Therefore, the probability of choosing the matching pair of socks is:
P(matching pair) = favorable outcomes / total outcomes
= 1 / 45 ≈ 0.0222
So, the probability of choosing the matching pair of socks is approximately 0.0222 or 2.22%.

Answer:
P = -390t +48,000P = 43,710 in 2003Step-by-step explanation:
A) We are given two pairs of (t, P): (0, 48000), (8, 44880). We can use these with the 2-point form of the equation of a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (44880 -48000)/(8 -0)(t -0) +48000
P = -3120/8t +48000
P = -390t +48000
__
B) In 2003, t = 11, so we have ...
P = -390(11) +48000 = 43710
The population in 2003 is predicted to be 43,710.

The correct answer is B. What are the ages of all your cousins?
Explanation:
Statistics focus on using numbers to analyze variables in a population or in a specific sample taken from this population. This means statistical questions can be answered by analyzing different features in a population. For example, you can wonder what is the time students on a class spend doing homework?.
According to this, the one that is a statistical question is "What are the ages of all your cousins?" because this question focuses on analyzing one variable or factor in a population; in this case, the ages of your cousins, which requires gathering information and then using numbers to represent and analyze this, which is the objective of statistics.

find the length of the line segment whose endpoints are ( 3, -2 ) and ( 5, 4 ) in simplest radical form
Answer:
2√10
Step-by-step explanation:
The length of this line segment lies along the hypotenuse of a right triangle. As we go from (3, -2) to (5, 4), the horizontal change is 2, and the vertical change 6. Apply the Pythagorean Theorem to find the length of the hypotenuse, which is also the line segment in question:
length = √[ 2^2 + 6^2 ] = √[4 + 36] = √40 = √4·√10 = 2√10

Given 2 secants to a circle from an external point, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20) ← distribute parenthesis on both sides
64 + 8x = 12 × 32 = 384 ( subtract 64 from both sides )
8x = 320 ( divide both sides by 8 )
x = 40
f(n+1)=f(n)-5. If f(1)=100, what is f(6)
Answer:
75
Step-by-step explanation:
Given:
f(1) = 100
f(n+1) = f(n) - 5
Solve for:
f(6)
Solution:
f(1) = 100
f(2) = f(1) - 5 = 100 - 5 = 100 - 1 x 5 = f(1) - 1 x 5
f(3) = f(2) - 5 = 100 - 5 - 5 = 100 - 2 x 5 = f(1) - 2 x 5
...
f(n) = f(n - 1) - 5 = 100 - (n-1) x 5 = f(1) - (n-1) x 5
=> f(6) = f(1) - (6-1) x 5 = 100 - 5 x 5 = 100 - 25 = 75

The same Honey is sold in two different size jars. Large jar= 540g for £4.10 Small jar= 360g for £2.81. By considering the amount of honey per penny, work out which jar is the best value for money. Working must be shown.
Answer:
From our calculations the large jar is the best value for money because a penny buys more honey
Step-by-step explanation:
In this problem we are expected to determine which purchase of honey is the cheapest ? large jar or small jar ?.We will determine which has the best value for money using the quantity a pound can purchase.
firstly for the large jar.
if £4.10 will purchase 540g of honey then,
£1.00 will purchase xg
cross multiplying to find x will have
[tex]x=[/tex] [tex]\frac{1.00*540g}{4.10}[/tex]
[tex]x= 131.7grams[/tex]
Hence for the large jar a penny would buy 131.7g of honey
secondly for the small jar
if £2.81 will purchase 360g of honey then,
£1.00 will purchase xg
cross multiplying to find x will have
[tex]x=\frac{1.00*360g}{2.81}\\x= 128.1gram[/tex]
Hence for the small jar a penny would buy 128.1g of honey

What is the equation of a line that has a slope of 2 and passes through the point (4,6) ?
Answer:
[tex]y-6=2\,(x-4)[/tex]
or in slope y-intercept form :
[tex]y=2x-2[/tex]
Step-by-step explanation:
The easiest way of find the answer for this is to use what is called the "point-slope" form of a line, because you are in fact given the value of the slope (m) and also a point [tex](x_0,y_0)[/tex] it goes through:
[tex]y-y_0=m\,(x-x_0)[/tex]
In our case the equation becomes:
[tex]y-y_0=m\,(x-x_0)\\y-6=2\,(x-4)\\[/tex]
This can also be written in the slope-intercept form by solving for "y" and operating to remove the parenthesis:
[tex]y-6=2\,(x-4)\\y=2x-8+6\\y=2x-2[/tex]
