What are some key features of sequence and series graphs?
Answer:
The key features that are unique to the graphs of sequences and series are that they are discrete.
Explanation:
That means that the graph is not a continuous line or curve that joins all the points. On the contrary, the graph is a set of separated dots, because the values are valid only for specific points.

sixty students were surveyed at random about their favorite music genre. Out of population 1,000 students, how many how many will prefer pop music?
So we want to know how many out of 1000 people did not listen to any type of the three music types that were surveyed If 30% of people listened to pop, 26% of people listened to rock and 20% of people listened country music. So first lets see how many people liked the three types of music: 30%+26%+20%=76%. So 24% of people did not like the three types of music that were surveyed. Finally we need to see how many people in 1000 is 24%. 24% out of 1000 people is 0.24*1000=240 people. So 240 people didn't like the 3 types of music.

Christine's parents gave her $70 to spend at the Topsfield Fair. She spent $10 on flowers and needs to buy vases. Each antique flower vase at the fair costs $3. Which represents the number of antique flower vases Christine can buy?
Answer:
a ≤ 20
Step-by-step explanation:
a = number of lower vases, in $
3a = cost of a flower vases, in $
10 + 3a = = cost of $10 worth of flowers plus a vases
10 + 3a ≤ 70 says that the cost of Christine's flowers and vases purchase
must be less than, or at most equal to $70.
Subtracting 10 rom both sides of the inequalour
gives us an equivalent inequality
3a ≤ 70 - 10 <---> 3a ≤ 60
Multiplying (or dividing) both sides by a positive number
gives us an equivalent inequality, so
a ≤ 60/3 <---> a ≤ 20
what is 4,649 divided by 39
Answer:
[tex]4649 \div 39 = 119.205128295[/tex]
Step-by-step explanation:
I hope it's help u
Answer:
119 R 8
Step-by-step explanation:
convert 4649 to tens place, write 1
46 - 39 = 7
drop the 4 in the tens place, write 1
74 - 39 = 35
drop the 9 in the ones place, write 9
359 - 351 = 8
• For each time we got 39 or another number, we wrote the multiple of that number we used to get the result.
• We got the remainder by the general subtraction.
A lion can run at a speed of 1.43 kilometers per minute. How fast can the lion run in miles per hour
The loin's speed in miles per hour will be 53.31 miles per hour.
What is velocity?Velocity is defined as the ratio of the distance moved by the object at a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.
It is given that:-
lion can run at a speed of 1.43 kilometres per minute.How fast can the lion run in miles per hourNow to find the speed of a lion in miles per hour we have the following relationship.

if A=-3+5i, B=4-2i and C=1+6i, where i is imaginary unit, then A-BC equals to what?
Multiplication is the process of multiplying. The value of A-BC is equal to -19-17i.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The value of BC is,
BC = (4-2i)×(1+6i)
BC = 4 + 24i - 2i -12i²
BC = 4 + 22i - 12(-1)
BC = 4 + 22i +12
BC = 16 + 22i
Now, the value of A-BC will be equal to,
A-BC = (-3+5i)-(16+22i)
= -3+5i-16-22i
= -19 - 17i
Hence, the value of A-BC is equal to -19-17i.

Answer:
mean: 106900
median: 8500
mode: 7,000, 8,000, and 11,000
Step-by-step explanation:
To calculate mean, add them all together and divide the number of how many numbers it has. For median make out the sequence from small to large. For this one is 5,000, 7, 000, 7,000, 8,000, 8,000, 9,000, 10,000, 11,000, 11,000, 1,000,000. The middle is between 8,000 and 9,000 so find it's middle number. The mode is the number that appears the most. In this case 7,000, 8000, 11,000 all appeared twice so they are the mode.

Some loose change (pennies, nickels, dimes, and quarters) found behind the couch. Brianna noticed more than half the coins were pennies. Geofrey noticed that there was at least one coin of each type. Michele noticed that you could not make change for the same amount using fewer coins. In the space below, write the total amount of change, in cents, that was found.
The total amount of change, in cents, that was found is determined as 96 cents.
Total amount of change
The total amount of change is calculated as follows;
let the total = T
there was at least one coin of each type
T = p + n + d + q
more than half of the coins were pennies
[tex]\frac{p+n + d + q }{2} \leq p[/tex]
Value of the coinspennies = $0.01nickels = $0.05dimes = $0.1quarters = $0.25more than half = pennies
next, we have; nickels + dimes + quarters
number of dimesy(dimes) = $0.25
y(0.1) = 0.25
y = 0.25/0.1
y = 2.5 ≅ 3
dimes = 3 coins
number of nickelssince dimes = 3 coins, number of nickels is now calculated as;
x(0.05) = 3(0.1)
x = (0.3)/(0.05)
x = 6 coins
nickels = 6 coins
Total coinsTotal coins = nickels + dimes + quarters + pennies
pennies must greater than 6 coins, since we can't have fewer coins.Total coins = nickels + dimes + quarters + pennies
let pennies = 7
Total coins = 6 + 3 + 1 + 7
Total coins = 17
half of 17 = 8.5
7 is less than half (8.5), number of pennies cannot be 7, since more than half of the coins are pennies.
let pennies = 11
Total coins = 6 + 3 + 1 + 11
Total coins = 21
half = 10.5
11 is more than half (10.5)more than half = number of pennies = 11
Total amount in cents11($0.01) + 6($0.05) + 3($0.1) + 1($0.25) = $0.96 = 96 cents

What is the slope of a line parallel to the line whose equation is x + y = -7. Fully
simplify your answer.
Answer:
slope = - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x + y = - 7 ( subtract x from both sides )
y = - x - 7 ← in slope- intercept form
with slope m = - 1
Parallel lines have equal slopes
then the slope of a line parallel to it is - 1

The base diameter and the height of a cone are both
equal to x units.
Answer:
π x³ /12 is the volume of the cone if A cone has a height of x and a diameter of x
Step-by-step explanation:
The base diameter and the height of a cone are both equal to x units
Diameter of cone = x units
Radius = Diameter /2
=> Radius of cone = x/2 units
Height of cone =x units
Volume of cone = (1/3) π r²h
r = radius h = height
=> Volume of cone = (1/3)π (x/2)² * x
= (1/3) π (x²/4) * x
= (1/12) π x³
= π x³ /12 cubic units
