Find the mode and median of the following data set
Red, purple, white, red, white, black, white, white, black, blue, black, red, black, blue, black, black
The mode of the given data set is black, and the median is blue.
Explanation:In the given data set Red, purple, white, red, white, black, white, white, black, blue, black, red, black, blue, black, black, the mode is the value(s) that occur(s) most frequently. The mode in this data set is black as it appears 6 times, which is more than any other value in the set.
The median is the middle value when the data set is arranged in order. To find the median, we first need to order the data set: black, black, black, black, black, blue, blue, purple, red, red, red, white, white, white, white. As there are 15 values in the set, the middle value is the 8th value, which is blue.

2, 5, 7, 12, 19 ...
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.

Create a real-world problem involving three lengths that form a right triangle
Give the measurement of the “legs”, then solve for the missing hypotenuse
Answer:
A ladder is leading on a wall that is 4 feet tall. The distance from the bottom of the ladder to the wall is 3 feet wide. Therefore, using the Pythagorean Theorem, 3^2 + 4^2 = 9 + 16 = 25. The square root of 25 is 5. The triangle's hypotenuse or the ladder's length is 5 feet.
The length of the hypotenuse is 25 feet
What is a right-triangle?
A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangle-triangle, is a triangle in which one angle is a right angle or two sides are perpendicular.
According to the given problem,
Let us assume,
A pole of length 15 feet cast a shadow of length 20 feet. What is the distance between the tip of the pole and the tip of the shadow?
Now, given,
Perpendicular = 15 feet
Base = 20 feet.
We know,
Hypotenuse² = Perpendicular² + Base²
⇒ H² = 15² + 20²
⇒ H² = 225 + 400
⇒ H² = 625
⇒ H = 25
Hence, we can conclude, the distance from the tip of the pole to the tip of the shadow is 25 feet.

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.

What is a function ?
A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.
A graph is given which shows a function. We need to find out domain and the range of this function based on the graph.
We know that , in a graph , domain is always represented on the x - axis whereas we represent range on the y - axis. Also , the domain of a function is the input provided to the function whereas the output we get is the range of the function.
In the graph shown : the dots on the x-axis are connected by -5 and 1 . This meant x coordinate is (-5,1) and dots on the y-axis are connected by -4 and 7. This meant y - coordinate is (-4 , 7).
So ,
The domain will be -5 ≤ x ≤ 1 .
The range will be -4 ≤ x ≤ 7 .
Therefore , the domain of the given function is -5 ≤ x ≤ 1 and range of the given function is -4 ≤ x ≤ 7.

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.
The function f(x) = 185(1.2)x models the number of foxes on a reservation x years from now. What does the 185 represent?
Answer:
It is the number of foxes in time t=0.
Step-by-step explanation:
If you evaluate f in x=0, you obtain that f(0) = 185*1.2⁰ = 185*1 = 185. This means that after 0 years, the number of foxes on the reservation is 185. In other words, the reservation starts with 185 years and then it grows. 185 here represents, as a result, the value of f, in other words the number of foxes, at time t=0.

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.

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.
