The given triangle is a scalene triangle and also an obtuse triangle.

A triangle is a two-dimensional geometrical figure that has three sides, three interior angles and three vertices.

For the given triangle, three sides are 9.8, 13.2, 5.2.

Three angles are 120°, 40°, 20°.

Therefore, the given triangle is a scalene triangle and also an obtuse triangle.

Since three sides of the given triangle are different.

Therefore, it is neither a isosceles triangle nor an equilateral triangle.

None of the angles is a right-angle.

Hence, it is not a right-angle triangle.

One of three angles of the given triangle is 120°.

Hence, it is not an acute triangle.

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.

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.

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:

In 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:

Therefore, the accumulated value of the investment after 4 years is $1,914.31.

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

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

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.

Answer:

I think the answer is x=1

Step-by-step explanation

Well since y=2 then I would multiply 2 with 3. And that is 6. Lastly, I would subtract 7 with 6 and you'll get 1 left over.

The value of x equals 1.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

x + 3y = 7

We have to substitute the value of y = 2.

x + (3 × 2) = 7

x + 6 = 7

Subtracting 6 from both sides,

x = 7 - 6 = 1

Hence the value of x is 1.

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.

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:

After 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:

So, Suruchi has 148 pages left to read.

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.

Area of the trapezoid is, 36 m²

Multiplication means to add number to itself a particular number of times. Multiply will be viewed as a process of repeated addition.

Given that;

A trapezoid has a base of 8 meters, a height of 6 meters, and a top side length of 4 meters.

Now, We know that;

Area of trapezoid = (a + b) h / 2

Here, We have;

a = 4 meters

b = 8 meters

h = 6 meters

Substitute all the values, we get;

Area of trapezoid = (a + b) h / 2

Area of trapezoid = (4 + 8) × 6 / 2

Area of trapezoid = 12 × 3

Area of trapezoid = 36 m²

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
