The other person was right they forgot to make it a negative
There are two sequence in mathematics, one is arithmetic and other is geometric sequence. Therefore, the 64th term of the arithmetic sequence is -1075.
What is Arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms, called common difference, is always the same. Another sequence is the geometric sequence.
The nth term of an arithmetic sequence is given by:
[tex]a_{n}[/tex]=a₁+(n-1)d
In which is the first term from−4,−21,−38 is a₁ -4
Common difference between two consecutive terms is d=-38-(-21)=-17
substituting in the above equation an=a1+(n-1)d
[tex]a_{n}[/tex]=-4+(n-1)(-17)
Since we have to find the 64th term of the arithmetic sequence we have to put n=64
[tex]a_{n}[/tex]=-4+(64-1)(-17)
[tex]a_{n}[/tex] =-4+(63)(-17)
[tex]a_{n}[/tex] =-1075
Therefore, the 64th term in the arithmetic sequence -4, -21, -38 is -1075.

A and B are two events.
Given that P(A)=0.25 , P(B)=0.2 , and P(A and B)=0.04 .
Drag and drop the answers into the boxes.
Answer:
Not independent.
Step-by-step explanation:
Given that P(A)=0.25 , P(B)=0.2 , and P(A and B)=0.04
To check whether A and B are independent.
Two events are independent if
P(A/B) = P(A) or P(B/A) = P(B) or P(AB) = P(A) P(B)
if any one of the above three is true also, the two events would be independent.
Let us find out first one
P(A/B ) = P(AB)/P(B) (as per conditional probability formula)
= 0.04/0.2=0.2
But P(A) = 0.25 and not equals P(A/B)
Hence we can conclude that A and B are not independent
because P(A/B) not equals P(A)

The one-time fling! Have you ever purchased an article of clothing (dress, sports jacket, etc.), worn the item once to a party, and then returned the purchase? This is called a one-time fling. About 20% of all adults deliberately do a one-time fling and feel no guilt about it! In a group of nine adult friends, what is the probability of the following?
Given that about 20% of adults do one time fling.
That is probability of a person doing fling is [tex]\frac{20}{100}=0.2[/tex] . Let it be p.
Then we have to use binomial distribution formula for the given problems.
b(x;n,p)=[tex]n_{C_{x}}p^{x}(1-p)^{n-x}[/tex]
A)Probability of no one has done one time fling means x is 0 here.
Hence [tex]b(0;9,0.2)=9_{C_{0} }(0.2)^{0}(1-0.2)^{9}[/tex]
[tex]=1X1X0.8^{9}=0.1342[/tex]
b) Probability of at least one person has done fling=1-(probability of no one has done)
=1-0.1342=0.8658
c)Probability of no more than two people have done one time fling means we need to add the probabilities for x=1,x=2 along with x=0.
[tex]b(1;9,0.2)=9_{C_{1}}(0.2)^{1}(1-0.2)^{8}[/tex]
[tex]=9X0.2X0.8^{8}=0.302[/tex]
[tex]b(2;9,0.2)=9_{C_{2}}0.2^{2}(1-0.2)^{7}[/tex]
[tex]=36X0.04X0.8^{7}=0.302[/tex]
Hence probability = 0.1342+0.302+0.302 = 0.7382

Answer:
(1) .20 (2) .40 (3) .12 (4) Less than
Step-by-step explanation:
You have to look at the table. There are 5 columns with 10 rows. 5x10=50
Then simply count the boxes that have the correct number of currency for instance, if they are asking for EXACTLY 1 dime then you rule out the ones that have 2 or 3 dimes and only the count the ones that have a single dime. So you count PDN but you would not count PDD. There are 20 boxes that have a single dime in them. 20 out of the 50 boxes. 20/50=.40 (answer 2)
The estimated probability that exactly two of the three coins Avery randomly picked are nickels is . 20
The estimated probability that exactly one of the three coins Avery randomly picked is a dime is . 40
The estimated probability that all three coins Avery randomly picked are pennies is . 12

The planets move around the sun in elliptical orbits with the sun at one focus. The point in the orbit at which the planet is closest to the sun is called perihelion, and the point at which it is farthest is called aphelion. These points are the vertices of the orbit. A planet's distance from the sun is 741,000,000 km at perihelion and 817,000,000 km at aphelion. Find an equation for the planet's orbit. (Place the origin at the center of the orbit with the sun on the x-axis. Use the following as necessary: x, y.)
Answer:
The shape of planetary orbits follows from the observed fact that the force of gravity between two objects depends on the square of the distance between them. ... Ellipses are closed so the planets we see in elliptical orbits stick around.
Step-by-step explanation:
We can write the equation for the planet's orbit:[tex]\[ \frac{x^2}{(817,000,000)^2} + \frac{y^2}{(741,000,000)^2} = 1 \][/tex]
How to find an equation for the planet's orbitTo find an equation for the planet's orbit, we can use the properties of an ellipse. The standard form of the equation for an ellipse with its center at the origin and major and minor axes along the x and y-axes is:
[tex]\[ \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 \][/tex]
In your problem, the distances at perihelion and aphelion are given as 741,000,000 km and 817,000,000 km, respectively. These distances represent the values of \(a\) and \(b\) in our equation.
So, we have:
[tex]\[ a = 817,000,000 \text{ km} \][/tex]
[tex]\[ b = 741,000,000 \text{ km} \][/tex]
Now, we can write the equation for the planet's orbit:
[tex]\[ \frac{x^2}{(817,000,000)^2} + \frac{y^2}{(741,000,000)^2} = 1 \][/tex]
This is the equation for the planet's elliptical orbit with the sun at one of the foci, where the origin is at the center of the orbit.

Start with the following conditional statement: If it is October 31, then it is Halloween.
a. State the converse of the statement.
b. State the inverse of the statement.
c. State the contrapositive of the statement.
( Answer in your own words, or don't answer at all )
The converse of 'If it is October 31, then it is Halloween' is 'If it is Halloween, then it is October 31.' The contrapositive is 'If it is not Halloween, then it is not October 31.'
Explanation:In logic and mathematics, we often explore the relationships between statements through their converses and contrapositives. Starting with the conditional statement, 'If it is October 31, then it is Halloween,' we can form the converse and contrapositive as follows:
The converse of the statement essentially flips the 'if' and 'then' components. As such, the converse of your statement would be: 'If it is Halloween, then it is October 31.'The contrapositive of a statement switches the 'if' and 'then' components and negates both. Hence, the contrapositive of your statement is: 'If it is not Halloween, then it is not October 31.'Learn more about Conditional Statements here:https://brainly.com/question/36974334

On Monday, Torrance practiced the violin for 4/10 of an hour. On Tuesday, he practiced for 1 6/8 of an hour. How much time did he practice in all?
Answer: [tex]2\frac{3}{20}[/tex]
Step-by-step explanation:
First, convert mixed numbers into improper fractions and simplify all fractions
[tex]\frac{4}{10}[/tex] ÷ [tex]\frac{2}{2}[/tex] = [tex]\frac{2}{5}[/tex]
[tex]1\frac{6}{8}[/tex] = [tex]\frac{8(1) + 6}{8}[/tex] = [tex]\frac{14}{8}[/tex] ÷ [tex]\frac{2}{2}[/tex] = [tex]\frac{7}{4}[/tex]
Next, find their sum. Remember to find the LCD and convert the fractions so they have like denominators.
Monday + Tuesday = Total
[tex]\frac{2}{5}[/tex] + [tex]\frac{7}{4}[/tex] = Total the LCD of 5 and 4 is 20
[tex](\frac{4}{4})\frac{2}{5}[/tex] + [tex](\frac{5}{5})\frac{7}{4}[/tex] = Total
[tex]\frac{8}{20}[/tex] + [tex]\frac{35}{20}[/tex] = Total
[tex]\frac{43}{20}[/tex] = Total
Then, convert the improper fraction into a mixed number
[tex]\frac{43}{20}[/tex] = [tex]2\frac{3}{20}[/tex]
The garden club earned \$15$15dollar sign, 15 per hour by weeding neighborhood gardens for ttt hours. A generous donor has agreed to double their earnings.
how much did the garden club earn in all?
The garden club earned $15 per hour by weeding neighborhood gardens for t hours.
A generous donor has agreed to double their earnings.
Double their earnings means we multiply by 2
So earning 15 per hour becomes 2*15 = 30 per hour
Given the number of hours is t
Earnings = $30 times number of hours
Earnings = 30 * t
Given that earning for 1 hour by weeding neightborhoods garden = $15
Then earning for 2 hours by weeding neightborhoods garden = $15*2= $30
Then earning for 3 hours by weeding neightborhoods garden = $15*3
Using same pattern earning for t hours by weeding neightborhoods garden = $15*t= $15t
Not it says that earning is doubled means you are getting 2*15 or $30 per hour
then new earning will be $30t in place of $15t
Hence final answer is $30t.

4. Calculate the gravity force between the Earth (m = 6*10^24 Kg) and the Moon (m = 7*10^22 Kg) when their distance is 4*10^8 m. (use G = 7*10^-11 Nm2/Kg2)
Fg = 1.8 * 10^52 N
the answer is given, but can someone explain how to get it?? I've tried for an hour to figure it out, but I am not getting it
r = 4*10^8 is the average distance from the earth to the moon (in meters).
m1 = 6*10^24 is the mass of the earth
m2 = 7*10^22 is the mass of the moon
G = 7*10^(-11) is the gravitational constant
Plug those values into the formula shown on the attached image (see below). Then simplify. When doing all that, I get the answer to be 1.8 * 10^20 newtons, so I'm not sure where your teacher is getting 52 as the exponent.

C. 2,552,129 cubic meters
D. 2,429,586 cubic meters
Answer
C. 2,552,129 cubic meters
Explanation
The volume of a pyramid = (1/3)Ah
Where A ⇒ area of the base
h ⇒ vertical height of the pyramid.
∴ Volume = (1/3) Ah
= 1/3 (229 × 229) × 146
= 1/3 × 52,441 × 146
= 1/3 × 7,656,386
= 2,552,128.667 m³
In whole number = 2,552,129 m³
a play is performed for a crowd of 400 people.adult ticket cost $22 each, student tickets cost $15 each,and tickets for children cost $13.50 each.the revenue for the concert is $7840.there are 40 more children at the concert than students.how many of each type of ticket are sold?
For this case we have the following variables:
A: Represents the number of adults
S: Represents the number of students
C: Represents the number of children
For the income we have:
[tex]22A + 15S + 13.50C = 7840[/tex] -----> (1)
Regarding the number of people at the concert we have:
[tex]A + S + C = 400[/tex] -----> (2)
If there are 40 more children than students, we have:
[tex]C = 40 + S[/tex] -----> (3)
We substitute C in the second equation and it remains:
[tex]A + S + 40 + S = 400[/tex]
[tex]A + 40 + 2S = 400[/tex]
[tex]A + 2S = 400-40[/tex]
[tex]A + 2S = 360[/tex]
[tex]A = 360-2S[/tex] --------> (4)
Substituting (3) and (4) in (1) we have:
[tex]22 (360-2S) + 15S + 13.50 (40 + S) = 7840[/tex]
[tex]7920-44S + 15S + 540 + 13.50S = 7840[/tex]
[tex]7920-7840 + 540 = 44S-15S-13.50S[/tex]
[tex]620 = 15.50S[/tex]
[tex]S = \frac{620}{15.50}[/tex]
[tex]S = 40[/tex]
So, there are 40 children.
Substituting S in (3) and obtaining C:
[tex]C = 40 + S[/tex]
[tex]C = 40 + 40[/tex]
[tex]C = 80[/tex]
Substituting S in (4):
[tex]A = 360-2 (40)\\A = 360-80\\A = 280[/tex]
Thus, 280 tickets of adults, 80 of children and 40 of students were sold.
Answer:
280 tickets for adults, 80 for children and 40 for students

An investment firm wants to create a billboard that displays an enlarged $1,000,000 bill. The actual size of the bill is 2.61 inches by 6.14 inches. If the billboard is 48 feet wide, what's the scale of the bill to the billboard?
A. 1′ = 8.71″
B. 1′ = 7.81″
C. 1″ = 8.71′
D. 1″ = 7.81′
We know how wide the billboard will be. Therefore, to know how much the original image should be enlarged, you have to divide the final width of the billboard between the current width of the invoice.
[tex]\frac{48 feet }{6.14 inches} =7.81\frac{feet}{inches}[/tex]
Therefore the correct answer is option D.
In order for the bill to cover the billboard, the bill must be expanded by a factor of 7.81 feet in length by inch in length.
