Answer:

\(\frac{1}{5} (2x+10)=4\) \(x=5\)

\(\frac{1}{3} (3x+9)=9\) \(x=6\)

Step-by-step explanation:

\(\frac{1}{5} (2x+10)=4\)

Multiply both sides of the equation by 5.

5 · \(\frac{1}{5}\) · \((2x+10)=\) 5 · 4

Simplify both sides of the equation.

\(2x+10=20\)

Subtract 10 from both sides of the equation.

\(2x=10\)

Divide each term by 2 and simplify.

\(x=5\)

--------------------------------------------------------------------

\(\frac{1}{3} (3x+9)=9\)

Substitute x for 6

\(\frac{1}{3} (3(6)+9)=9\)

Multiply 3 · 6

\(\frac{1}{3} ((18)+9)=9\)

Add 18 + 9

\(\frac{1}{3} (27)=9\)

Divide \(\frac{1}{3}\) ÷ 27

9 = 9

The population of interest for this student is the students whom are enrolled in statistics classes.

Step-by-step explanation:

Sampling

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

For example:

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.

The population of interest are all residents of New York State.

A simple random sample of 500 students was selected from all the students enrolled in statistics classes.

This means that the population of interest for this student is the students whom are enrolled in statistics classes.

Answer and Step-by-step explanation:

The answer is 2 (which is equal to x).

If you were to plug 2 in to the function, the result if 30.

\(x^{3}+ 6x^{2} -x\\\\\\\\(2)^3+6(2)^2 - 2 = 30 = f(2)\)

Answer:

58.61%

Step-by-step explanation:

Your total backyard is 18ft * 9ft = 162 ft^2

Your patio is 5ft * 8ft = 40 ft^2

Your Garden is 4ft * 7ft = 28 ft^2

Your walkway is 3ft * 9ft = 27 ft^2

Add all those areas together you have 95 ft^2

95 of 162 = 58.61%

Answer:

-3,4

Step-by-step explanation:

just follow up the other coordinates

You can write three consecutive even numbers as follow:

2x, 2(x + 1), 2(x + 2)

Considert that the sum of the first number and the second one is 146, then, you have:

2x + 2(x + 1) = 146

Solve the previous equation for x, as follow:

2x + 2x + 2 = 146 simplify like terms left side

4x + 2 = 146 subtract 2 both sides

4x = 146 - 2

4x = 144 divide by 4 both sides

x = 144/4

x = 36

Next, replace the previous value of x into the expressions for the even numbers:

2x = 2(36) = 72

2(x + 1) = 2(36 + 1) = 74

2(x + 2) = 2(36 + 2) = 76

Hence, the even numbers are 72, 74 and 76

Answer:

\(x=140\)

Step-by-step explanation:

Do not get grounded.

An angle at a point is 360°.

So, \(x+120+70+30=360\)

\(x+220=360\)

\(x=140\)

Remember this All the angles around a point when added gives a 360° !

Thus,

30+ X +70+120 = 360

=> X + 220 = 360

Answer:

it's really hard to see the numbers.. but I can explain how to do it. the 5 is on the x axis and the 0 is on the y axis. if you from 0 to 5 on the x axis and the line crosses through that point then it is true.

As Jim has $30 more than Max, as per this, Max has $270.

Let's assume Max's savings as 'x' dollars.

We have:

2/5 of Jim's savings is equal to 4/9 of Max's savings.

(2/5) * Jim's savings = (4/9) * Max's savings

We also know that Jim has $30 more than Max.

Jim's savings = Max's savings + $30

So,

(2/5) * Jim's savings = (4/9) * Max's savings

(2/5) * (Max's savings + $30) = (4/9) * Max's savings

To solve for Max's savings, we can solve this equation:

(2/5) * (x + $30) = (4/9) * x

So, for x:

(2/5) * (x + $30) = (4/9) * x

Multiplying both sides by 45 (the least common denominator of 5 and 9) to eliminate the fractions:

18(x + $30) = 20x

18x + 540 = 20x

540 = 20x - 18x

540 = 2x

x = 270

Therefore, Max has $270.

the graph of Andrew's distance from home will look like this: Time (x-axis)  0  1  2  3  4  5  6  7  8  9  10 Distance (y-axis)  0  5  10 10 15 20 20 24 28 32  0

Graph is a data structure which is used to represent relationships between objects or data points. It is composed of nodes and edges, where nodes are the objects and edges are the connections between the objects. Graphs are used to represent mathematical equations, networks, and data structures such as trees. They are also used to represent relationships between data points in large datasets. Graphs can be used to represent both directed and undirected relationships, and are commonly used in many fields including computer science, engineering, mathematics, and data science.

From the given information, we can create a graph that shows Andrew's distance from home as he drives to the store, to the bank, and back again. The x-axis will represent time (in minutes), and the y-axis will represent the number of blocks away from home.

At time zero, Andrew is at his home, so the graph will begin with a point at (0, 0). As he travels to the store, the graph will move up 5 blocks for every minute he drives. Therefore, after 2 minutes, he will be 10 blocks away from home, so the graph will be at (2, 10). After he stops at the store for 2 minutes, he will still be 10 blocks away from home, so the graph will stay at (2, 10).

When he leaves the store and drives to the bank, he will move 5 blocks each minute. After 5 minutes, he will be 25 blocks away from home, so the graph will be at (5, 25). After he stops at the bank for 3 minutes, he will still be 25 blocks away from home, so the graph will remain at (5, 25).

Finally, when he drives home, he will move 4 blocks for each minute he drives. After 5 more minutes, he will be back at his home, so the graph will be at (10, 0).

Therefore, the graph of Andrew's distance from home will look like this:

Time (x-axis)  0  1  2  3  4  5  6  7  8  9  10

Distance (y-axis)  0  5  10 10 15 20 20 24 28 32  0

The time spent higher than 26 meters above the ground is 0.42 minutes. Answer: 0.42

A Ferris wheel is 30 meters in diameter and boarded from a platform that is 4 meters above the ground.

The six o'clock position on the Ferris wheel is level with the loading platform.

The wheel completes 1 full revolution in 2 minutes.

We have to find how many minutes of the ride are spent higher than 26 meters above the ground.

So, let's start with some given data,Consider the height of a person at the six o'clock position = 4 meters

So, the height of a person at the highest point = 4 + 15 = 19 meters (since the diameter is 30 meters, the radius will be 15 meters)

Also, the height of a person at the lowest point = 4 - 15 = -11 meters

Therefore, the Ferris wheel completes one cycle from the lowest point to the highest point and back to the lowest point.

So, the total distance travelled will be = 19 + 11 = 30 meters.

Also, we are given that the wheel completes 1 full revolution in 2 minutes.

We need to calculate the time spent higher than 26 meters above the ground.

So, the angle between the 6 o'clock position and 2 o'clock position will be equal to the angle between the 6 o'clock position and the highest point.

This angle can be calculated as follows:

Angle = Distance travelled by the Ferris wheel / Circumference of the Ferris wheel * 360 degrees

Angle = 30 / (pi * 30) * 360 degrees

Angle = 360 degrees / pi

= 114.59 degrees

So, the total angle between the 6 o'clock position and the highest point is 114.59 degrees.

Now, we need to find out how much time is spent at an angle greater than 114.59 degrees.

This can be calculated as follows:

Time = (Angle greater than 114.59 degrees / Total angle of the Ferris wheel) * Total time taken

Time = (180 - 114.59) / 360 * 2 minutes

Time = 0.42 minutes

Answer:

To determine the possible degree(s) of a function from the graph alone, you need to examine the behavior of the graph at the extremes (far left and far right) and consider the number of turning points or changes in direction. Here's a step-by-step approach:

Look at the far left side of the graph: Determine the behavior of the graph as it approaches negative infinity. Does the graph approach a specific value, such as a horizontal line (asymptote) or the x-axis? If the graph approaches a horizontal line, it suggests a polynomial function of even degree. If the graph approaches the x-axis, it indicates a polynomial function of odd degree or possibly a function with a root of multiplicity greater than one.

Look at the far right side of the graph: Determine the behavior of the graph as it approaches positive infinity. Similar to step 1, observe if the graph approaches a specific value or a horizontal line. The behavior at the far right side should be consistent with the behavior at the far left side. This can help you identify if the function is even or odd degree.

Examine the number of turning points or changes in direction: Count the number of times the graph changes direction. These points are where the slope of the graph changes from positive to negative or vice versa. The number of turning points can provide an indication of the degree of the polynomial. For example, if there are two turning points, it suggests a polynomial function of degree 3.

Remember that this method provides potential degrees, but it may not definitively determine the exact degree of the function. Additional information or analysis might be required for a more accurate determination.
