Answer:

Step-by-step explanation:

Find the value of s on one side of the equation to isolate it.

1.1=s+2.3/3

First, switch sides.

\(\sf{\dfrac{s+2.3}{3}=1.1}\)

Multiply by 3 from both sides.

\(\sf{\dfrac{3\left(s+2.3\right)}{3}=1.1* \:3}\)

Solve.

1.1*3=3.3

s+2.3=3.3

Then, subtract by 2.3 from both sides.

s+2.3-2.3=3.3-2.3

Solve.

Subtract.

3.3-2.3=1.0=1

s=1

Therefore, the final answer is s=1.

The probability of getting a five or higher on the first roll and getting a total of 7 on the two dice is 1/18.

Step 1: Calculate the probability of getting a five or higher on the first roll.
There are two favorable outcomes (rolling a 5 or a 6), and there are six possible outcomes (rolling 1, 2, 3, 4, 5, or 6) on the first dice. So, the probability of getting a five or higher is:

P(5 or higher) = Favorable Outcomes / Total Outcomes = 2/6 = 1/3

Step 2: Calculate the probability of getting a total of 7 on the two dice.
There are six possible outcomes on each dice, making 6 x 6 = 36 possible outcomes in total. There are six favorable outcomes that result in a total of 7: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). So, the probability of getting a total of 7 is:

P(total of 7) = Favorable Outcomes / Total Outcomes = 6/36 = 1/6

Step 3: Calculate the probability of both events occurring.
Since the two events are independent, you can multiply their probabilities to find the probability of both events occurring:

P(5 or higher on first roll and total of 7) = P(5 or higher) × P(total of 7) = (1/3) × (1/6) = 1/18

So, the probability of getting a five or higher on the first roll and getting a total of 7 on the two dice is 1/18.

The derivative of \(r\) with respect to \(\theta\) can be found using the chain rule. Let's proceed with the differentiation:

\frac{dr}{d\theta} = \frac{d}{d\theta}\left(\cos\left(\frac{\theta}{3}\right)\right)

To differentiate \(\cos\left(\frac{\theta}{3}\right)\), we treat \(\frac{\theta}{3}\) as the inner function and differentiate it using the chain rule. The derivative of \(\cos(u)\) with respect to \(u\) is \(-\sin(u)\), and the derivative of \(\frac{\theta}{3}\) with respect to \(\theta\) is \(\frac{1}{3}\). Applying the chain rule, we have:

\frac{dr}{d\theta} = -\sin\left(\frac{\theta}{3}\right) \cdot \frac{1}{3}

Now, let's evaluate this derivative at \(\theta = \pi\):

\frac{dr}{d\theta} \bigg|_{\theta=\pi} = -\sin\left(\frac{\pi}{3}\right) \cdot \frac{1}{3}

The value of \(\sin\left(\frac{\pi}{3}\right)\) is \(\frac{\sqrt{3}}{2}\), so substituting this value, we have:

\frac{dr}{d\theta} \bigg|_{\theta=\pi} = -\frac{\sqrt{3}}{2} \cdot \frac{1}{3} = -\frac{\sqrt{3}}{6}

Therefore, the slope of the tangent line to the polar curve \(r = \cos(\theta / 3)\) at the point specified by \(\theta = \pi\) is \(-\frac{\sqrt{3}}{6}.

The average number of miles he will ride each day to meet his goal is 6.6 miles

He wants to ride his bicycle 30.4 miles this week.

He has already ridden 4 miles.

He rides 4 more days.

Therefore, the average number of miles he would have to ride each day to meet his goal can be calculated as follows:

let

x = number of miles driven

Hence, the equation can be represented as follows;

4x + 4 = 30.4

Therefore,

4x + 4 = 30.4

4x + 4 - 4 = 30.4 - 4

4x = 26.4

x = 26.4 / 4

x = 6.6

t^-1 is the inverse of t.

To find the inverse of the given isomorphism t, we need to find a function t^-1 : r2 → p1 such that t(t^-1(x,y)) = (x,y) for all (x,y) in r2.

Let (x,y) be an arbitrary element of r2. We want to find (a,b) in p1 such that t(a,b) = (x,y). Using the definition of t, we have:

t(a,b) = (8b, a-b)

Setting this equal to (x,y), we get the system of equations:

8b = x
a - b = y

Solving for a and b in terms of x and y, we get:

a = y + x/8
b = x/8

Thus, we have found a function t^-1 : r2 → p1 given by:

t^-1(x,y) = (y + x/8, x/8)

We can check that this function is indeed the inverse of t:

t(t^-1(x,y)) = t(y + x/8, x/8) = (8(x/8), y + x/8 - x/8) = (x,y)

Therefore, t^-1 is the inverse of t.

x = 6 and x = 3

Step-by-step explanation:

Given

Given that the triangles are congruent.

According to the SAS (Side-Side-Side)

AC = DC

AB = DB

so

AC = DC

substituting AC = 5x-2 and DC = 3x+10

5x-2 = 3x+10

5x-3x = 10+2

2x = 12

divide both sides by 2

2x/2 = 12/2

x = 6

and

AB = DB

substituting AB = 5x and DB = 4x+3

5x = 4x+3

5x-4x = 3

The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.

The population proportion who participated in voting is given as 63% of all registered voters.

This means that out of every 100 registered voters, 63 participated in voting.

In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.

Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .

Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.

It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.

The correct answer is: Seahawks; they have a larger median value of 23 inches.

To determine which team has the largest overall size hat for their players, we need to compare the central tendency measures of the two sets of data.

The best measure of center to use in this case is the median, which represents the middle value of the data when arranged in ascending or descending order.
Looking at the two tables, we can see that the median value for the Pelicans is 22 inches, while the median value for the Seahawks is 23 inches.

Therefore, the Seahawks have a larger median hat size and can be considered to have the largest overall size hat for their players.

The right response is that the two linear equation never intersect , because the graph of these two linear equation will be two parallel lines.

How many types of solution are there for two linear equations ?

There are 2 types of solution :
Consistent :

A consistent system is said to be an independent system if it has a single solution.

A consistent system is said to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide, so the equations represent the same line. Each point on the line represents a pair of coordinates that fits the system. So there are an infinite number of solutions.

Non-consistent :

Another type of system of linear equations is the inconsistent system, in which the equations represent two parallel lines. The lines have the same slope and different y-intercepts. There are no common points for both lines; therefore, there is no solution to the system and if we draw the graph of these equations then the graphs of both equation becomes parallel to each other.

The two linear equations never intersect.

When a system of two linear equations in two variables has no solution, it means that there is no set of values for the variables that satisfies both equations simultaneously. Geometrically, this corresponds to the two lines represented by the equations being parallel. Since parallel lines never intersect, the statement "The two linear equations never intersect" accurately describes the situation.

If the two linear equations were graphed on a coordinate plane, they would appear as two distinct lines that run parallel to each other without ever crossing or intersecting. This indicates that there is no common point of intersection between the lines, and therefore no solution exists for the system of equations.

It is important to note that this scenario is different from the case where the two linear equations represent the same line. In that case, the equations would be equivalent, and every point on the line would satisfy both equations. However, when there is no solution, it means that the lines do not share any common points and never intersect.
