Explain how to describe the data on a histogram.
Answer:
In a histogram, the distribution of the data is symmetric if it has one prominent peak and equal tails to the left and the right. The Median and the Mean of a symmetric dataset are similar.
Step-by-step explanation:
Answer:
You can consider a cluster, which is a group of the bars, and this could help define the higher frequency in these intervals. Another way is the peak which is there the frequency is highest. There can also possibly be bars on a certain area, meaning the frequency is 0. You can also describe a histogram as symmetrical, evenly distributed, or none of those.
Step-by-step explanation:
A cluster is a group of bars, meaning the frequency is higher in these intervals. A peak is a bar that is higher than the other bars around it. So a peak is where the frequency is highest. Intervals on a histogram where there are no bars means the frequency is 0. If the graph is symmetrical, then the data are evenly distributed.
A cluster is a group of bars, meaning the frequency is higher in these intervals.
A peak is a bar that is higher than the other bars around it.
A peak is where the frequency is highest.
Intervals on a histogram where there are no bars means the frequency is 0.
If the graph is symmetrical, then the data are evenly distributed.

Yes, this makes sense since the data on the box-o-gram fall within the data given in the chart at the top of the worksheet.
You flip a coin and roll a regular six-sided number cube. Find the probability of flipping tails and rolling an even number
Answer:
Since flipping a coin and rolling a 6-sided die are independent events ,thus the probability of getting head and an even number is just the product of the individual probability of events.
Let A be the event of getting a head ,and B be the event of getting an even number on die.
therefore, P(A and B)=P(A) P(B)=(1/2)*(3/6)=1/4=0.25

The very busy Freshman class is selling tickets for an upcoming field hockey game. The class sells 20 more student tickets than adult tickets. The adult tickets cost $4 and the student tickets cost $2. The class made a total of $280 from ticket sales. How many of each type of ticket did they sell? Elaborate and clarify your reasoning.
1a. Define the variables in this system
b. Create equations to describe the relationships in this system between the variables
Answer:
60 student tickets and 40 adult tickets were sold
Step-by-step explanation:
Let s represent student tickets and a adult tickets, then the system of equations can be written as
s - a = 20 →(1)
2s + 4a = 280 → (2)
Multiply (1) by 4 and add to (2) to eliminate a
4s - 4a = 80 → (3)
Add (2) and (3) term by term
6s = 360 ( divide both sides by 6 )
s = 60
Substitute s = 60 into (1)
60 - a = 20 ( subtract 60 from both sides )
- a = - 40 ( multiply both sides by - 1 )
a = 40
Thus
60 student and 40 adult tickets were sold.

What are the next two terms in this sequence?
Final answer:
The next two terms in the sequence 2, 5, 7, 12, 19 are 30 and 43, which are derived by following a pattern of increasing each term by the next prime number.
Explanation:
To determine the next two terms in the sequence 2, 5, 7, 12, 19, we need to look for a pattern. Let's examine the differences between consecutive terms:
5 - 2 = 3
7 - 5 = 2
12 - 7 = 5
19 - 12 = 7
It seems that there is no straightforward arithmetic progression, but we can notice a pattern in the differences: 3, 2, 5, 7. The differences themselves seem to be part of a sequence. If we take subtract 1 from the second term, add 3 to the third term, and add 2 to the fourth term, we get a sequence of primes: 3, 2, 5, 7. Following that pattern, the next prime numbers are 11 and 13.
So if we add 11 to the last term (19), we get 30 as the next term. Adding 13 to 30 gives us 43 as the term after that. Therefore, the next two terms in the sequence should be 30 and 43.

Suruchi is reading a book that is 333 pages long. So far, she has read 5/9 of the book. How many pages does Suruchi have left to
read?
Final answer:
Suruchi has read 5/9 of a 333-page book, which equates to approximately 185 pages. Therefore, she has 148 pages left to read.
Explanation:
The student is asking how many pages Suruchi has left to read from a book that is 333 pages long given that she has already read 5/9 of the book. To find the number of pages read, we multiply 5/9 by the total number of pages:
Pages read = (5/9) imes 333After calculating, Suruchi has read 185 pages since 5/9 of 333 is approximately 185. Therefore, the number of pages she has left to read is:
Pages left = Total pages - Pages readPages left = 333 - 185 = 148So, Suruchi has 148 pages left to read.

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 30% salt and Solution B is 70% salt. She wants to obtain 120 ounces of a mixture that is 65% salt. How many ounces of each solution should she use?
Answer:
Solution A: 15 ounces
Solution B: 105 ounces
Step-by-step explanation:
A + B = 120
A = 120 - B
0.3A + 0.7B = 0.65(120)
0.3A + 0.7B = 78
0.3(120 - B) + 0.7B = 78
36 - 0.3B + 0.7B = 78
0.4B = 42
B = 105
A = 120 - 105
A = 15
Answer:
15 ounces solution A
105 ounces solution B
Step-by-step explanation:
Let x be the amount of solution A
We need a total of 120 ounces of solution
Therefore we need
120-x ounces of solution B
Take the ounces of solution A times the percentage salt + the ounces of solution B times the percentage salt and this should equal the total ounces time the percentage sale
.3 x + (120-x) *.7 = 120 * .65
Distribute
.3x +84 -.7x = 78
Combine like terms
-.4x = -6
Divide each side by -.4
-.4x/-.4 = -6/-.4
x =15
We need 15 ounce of solution A
We need 120 ounces total
120-15 =105 ounces of solution B
A spinner has four unequal parts. Tony spun the spinner 16 times. The spinner landed on
red 1 time, blue 2 times, yellow 3 times and green 10 times. Using this data, what is the
most likely outcome on the next spin?
red
blue
green
yellow
Answer:Green
Step-by-step explanation:
Final answer:
Based on past spins, the most likely outcome for the next spin is green, as it was landed on the most frequently.
Explanation:
If a student spun a spinner 16 times and it landed on red 1 time, blue 2 times, yellow 3 times, and green 10 times, the most likely outcome on the next spin would be green.
This conclusion is based on the relative frequency of the outcome for each color so far. The frequency suggests that the spinner is biased toward the green section since it has been landed on the most in this small sample of spins. Assuming the conditions remain the same and there's no alteration to the spinner, the probability of landing on a particular color is proportional to the number of times it has been landed on in the past.
Therefore, with the information provided and based on past occurrences, green is the most likely outcome for the next spin on this specific spinner.
Find the accumulated value of an investment of $1,400 at 8% compounded quarterly for 4 years.
Final answer:
The accumulated value of a $1,400 investment at an 8% annual interest rate, compounded quarterly for 4 years, using the compound interest formula, is $1,914.31.
Explanation:
To calculate the accumulated value of an investment with compound interest, we use the formula A = P(1 + r/n)^(NT), where:
P is the principal amount (the initial amount of money)r is the annual interest rate (in decimal form)N is the number of times the interest is compounded per yearT is the time the money is invested for, in yearsIn this case, the student invests $1,400 at an 8% annual interest rate, compounded quarterly for 4 years.
Using the formula:
Convert the annual rate to a decimal: 8% = 0.08
Determine the number of compounding periods per year: Quarterly means 4 times per year
Calculate the number of compounding periods: 4 years × 4 times per year = 16 total compounding periods
Calculate the accumulated value: A = 1400(1 + 0.08/4)^(4×4)
Plugging in the values:
A = 1400(1 + 0.02)^(16)A = 1400(1.02)^16A = 1400 × (1.367363)A = $1,914.31Therefore, the accumulated value of the investment after 4 years is $1,914.31.

Determine the approximate ordered pair for f(x) = g(x). the graph of two linear functions negative 4 times x plus 15 times y equals negative 300 and 20 times x plus 4 times y equals negative 20
Answer:
(x, y) ≈ (2.848, -19.241)
Step-by-step explanation:
I find it much easier to work with the problem statement when math expressions are written using numbers and symbols. We assume you have ...
-4x +15y = -300
20x +4y = -20
Dividing the second equation by 4 and subtracting the x-term gives ...
y = -5-5x
Substituting that into the first equation, we get ...
-4x +15(-5-5x) = -300
-79x -75 = -300
x = -225/-79 = 2 67/79 ≈ 2.8481
Substituting this into the equation for y gives ...
y = -5(x +1) = -5(3 67/79) = -19 19/79 ≈ -19.2405
The approximate solution is ...
(x, y) = (2.8481, -19.2405)
