Sean wants to practice his soccer skills for at least 2.5 hours this week write inequality to represent the number of hours Sean will spend practicing this week. Graph the solution to your inequality from part A on the number line below

The expressions on the left and right sides are equivalent in part b) and not equivalent in part a) and c).

a) The expressions on the left and right sides are not equivalent.

The left side states that for all values of x, if there exists a value of y such that Q(x, y) is true, then P(x) must be true. The right side states that for all values of x, both the existence of a value of y such that Q(x, y) is true and P(x) must be true.

b) The expressions on the left and right sides are equivalent.

The left side states that it is not the case that there exists an x such that for all values of y, P(x, y) is true. The right side states that for all values of x, there exists a value of y such that either P(x, y) is true or Q(x, y) is true.

c) The expressions on the left and right sides are not equivalent.

The left side states that for all values of x, there exists a value of y such that P(x) implies Q(x, y). The right side states that for all values of x, P(x) implies that there exists a value of y such that Q(x, y) is true.

Answer:

Hispanics Account for More than Half of Nation's Growth in ...

The 2010 Census counted 50.5 million Hispanics in the United States, making up 16.3% of the total population. The nation's Latino population, which was 35.3 million in 2000, grew 43% over the decade.

Step-by-step explanation:

This answer provides step by step guidance to understanding a data set comprising of the Hispanic population in the US. It guides through the interpretation of the provided spreadsheet, the creation and interpretation of histograms and box plots, and the identification and analysis of outliers.

Since I'm not able to interact directly with your provided spreadsheet and tools, I'll guide you along the process. On Brainly, tutors can't provide images or interactive tools.

The 'Number' column represents the actual count of Hispanic/Latino population in a given location. The '% of Total Population' column represents the proportion of the Hispanic/Latino population against the total population in the same location. The 'Total' column, in this context, likely represents the total population of a given location.

For histogram and box plot creations, first copy the column of data you need, then paste it into the respective tool. Make sure to set meaningful limits and label your graphics appropriately. These visuals will help in understanding the distribution of the data.

Analyze your plots. Look for whether the data is symmetric (normal), skewed left (negative) or skewed right (positive). 'Spread' refers to the variability in your data, a key indicator might be the difference between maximum and minimum values discussed in Part B.

Central tendencies can be understood as the 'middle' or 'average' of the data. In a histogram, look for peaks, which represent the mode of the distribution. For a box plot, calculate the median (Q2), essentially the mid-point of the plotted data.

To find min/max values excluding outliers, look for the smallest/largest value that falls within the range defined by Q1 - 1.5*(IQR) and Q3 + 1.5*(IQR). Outliers are the data points outside this range. Check back to see which states these outliers correspond to.

Compare the given 16.3% to your box plot. Depending on where it fits within the plot's quartiles, it may or may not be surprising due to differing state-level proportions vs the overall distribution. Explanation might involve immigration, cultural hubs, or state-specific policies among others.

Step-by-step explanation:

A shop is open 9 am - 7 pm. the function r(t), graphed above, gives the rate at which customers arrive (in people/hour) at time t, the line will vanish at 9 am + 2.5 hours = 11:30 am.

Since the salespeople can serve customers at a rate of 75 people per hour, the net rate at which customers are added to the line is given by:

Net rate = R(t) - 75

where R(t) is the rate at which customers arrive.

The line will vanish when the net rate becomes zero, which means that the rate at which customers are added to the line is equal to the rate at which they are served. Thus, we have:

R(t) - 75 = 0

Solving for t, we get:

R(t) = 75

Looking at the graph, we can see that R(t) is equal to 75 at approximately 2.5 hours after 9 am. Therefore, the line will vanish at 9 am + 2.5 hours = 11:30 am.

Gender and ethnicity are categorical variables and therefore, the standard deviation cannot be calculated for variables.

The standard deviation is a measure of the spread or dispersion of the data around the mean. In other words, it tells us how far each data point in a set is from the average of the set.

When we analyze data, it's important to understand how much variation there is in the data, and the standard deviation is one way to do this.

When it comes to the three dependent variables in the data set (gender, age, and ethnicity), it is important to understand that the standard deviation is only calculated for numerical data.

However, age is a numerical variable, and the standard deviation can be calculated for it.

To find the standard deviation of the ages, we need to first find the mean of the ages and then subtract each age value from the mean and square the result.

Next, we add up all the squared deviations and divide by the number of ages minus one. Finally, we take the square root of the result, and that gives us the standard deviation of the ages in the data set.

To determine the change in angular momentum (ΔL) of a cylinder from t = 0 to t = t0, a student can use the equation:

ΔL = I * Δω

where ΔL is the change in angular momentum, I is the moment of inertia of the cylinder, and Δω is the change in angular velocity.

To calculate Δω, the student needs to know the initial and final angular velocities, ω0 and ωt0, respectively. The change in angular velocity can be calculated as:

Δω = ωt0 - ω0

Once Δω is determined, the student can use the moment of inertia (I) of the cylinder to calculate ΔL using the equation mentioned earlier.

The moment of inertia (I) depends on the mass distribution and shape of the cylinder. For a solid cylinder rotating about its central axis, the moment of inertia is given by:

I = (1/2) * m * r^2

where m is the mass of the cylinder and r is the radius of the cylinder.

By substituting the known values for Δω and I into the equation ΔL = I * Δω, the student can calculate the change in angular momentum (ΔL) of the cylinder from t = 0 to t = t0.

It's important to note that this method assumes that no external torques act on the cylinder during the time interval. If there are external torques involved, the equation for ΔL would need to include those torques as well.

When a 666-sided fair die is rolled, then the probability of rolling greater than 4 is  0.9940 or 99.40%.

Given that the die is fair and has 666 sides. So, each face of the die will have a probability of 1/666, i.e.,

p(1) = p(2) = ... = p(666) = 1/666.

The probability of rolling greater than 4 is P(roll greater than 4), which is the sum of the probabilities of rolling a 5, 6, 7, 8, 9, ..., 666. So,

P(roll greater than 4) = p(5) + p(6) + p(7) + ... + p(666)

P(roll greater than 4) = (1/666) + (1/666) + (1/666) + ... + (1/666)

(There are 661 terms)P(roll greater than 4) = 661(1/666)

P(roll greater than 4) = 0.9940 (rounded to four decimal places)

Hence, the probability of rolling greater than 4 is 0.9940 or 99.40%.

Alternatively, the probability of rolling greater than 4 is

   1 - P(roll less than or equal to 4)P(roll greater than 4)

= 1 - P(roll less than or equal to 4)P(roll greater than 4)

= 1 - (p(1) + p(2) + p(3) + p(4))P(roll greater than 4)

= 1 - (4/666)P(roll greater than 4)

= 1 - 0.0060P(roll greater than 4)

 = 0.9940 (rounded to four decimal places)

Hence, the probability of rolling greater than 4 is 0.9940 or 99.40%.

Step-by-step explanation:

These are the degrees because of the Triangle Sum Theorem which states that The sum of the measures of the angles in a triangle is 180°. So angle C for example is 27 because angle A is 53 and angle B is 100 add both of those and you get 153 so our equation would be 153+c=180, c being the angle, so then to solve this you do do 180-153 and that equals 27 so therefore, 153+27=180.

Let A(t) denote the amount of salt (in ounces, oz) in the tank at time t (in minutes, min).

Salt flows in at a rate of

\(\dfrac{dA}{dt}_{\rm in} = \left(17 (1 + 15 \sin(t)) \dfrac{\rm oz}{\rm gal}\right) \left(8\dfrac{\rm gal}{\rm min}\right) = 136 (1 + 15 \sin(t)) \dfrac{\rm oz}{\min}\)

and flows out at a rate of

\(\dfrac{dA}{dt}_{\rm out} = \left(\dfrac{A(t) \, \mathrm{oz}}{180 \,\mathrm{gal} + \left(8\frac{\rm gal}{\rm min} - 8\frac{\rm gal}{\rm min}\right) (t \, \mathrm{min})}\right) \left(8 \dfrac{\rm gal}{\rm min}\right) = \dfrac{A(t)}{180} \dfrac{\rm oz}{\rm min}\)

so that the net rate of change in the amount of salt in the tank is given by the linear differential equation

\(\dfrac{dA}{dt} = \dfrac{dA}{dt}_{\rm in} - \dfrac{dA}{dt}_{\rm out} \iff \dfrac{dA}{dt} + \dfrac{A(t)}{180} = 136 (1 + 15 \sin(t))\)

Multiply both sides by the integrating factor, \(e^{t/180}\), and rewrite the left side as the derivative of a product.

\(e^{t/180} \dfrac{dA}{dt} + e^{t/180} \dfrac{A(t)}{180} = 136 e^{t/180} (1 + 15 \sin(t))\)

\(\dfrac d{dt}\left[e^{t/180} A(t)\right] = 136 e^{t/180} (1 + 15 \sin(t))\)

Integrate both sides with respect to t (integrate the right side by parts):

\(\displaystyle \int \frac d{dt}\left[e^{t/180} A(t)\right] \, dt = 136 \int e^{t/180} (1 + 15 \sin(t)) \, dt\)

\(\displaystyle e^{t/180} A(t) = \left(24,480 - \frac{66,096,000}{32,401} \cos(t) + \frac{367,200}{32,401} \sin(t)\right) e^{t/180} + C\)

Solve for A(t) :

\(\displaystyle A(t) = 24,480 - \frac{66,096,000}{32,401} \cos(t) + \frac{367,200}{32,401} \sin(t) + C e^{-t/180}\)

The tank starts with A(0) = 15 oz of salt; use this to solve for the constant C.

\(\displaystyle 15 = 24,480 - \frac{66,096,000}{32,401} + C \implies C = -\dfrac{726,594,465}{32,401}\)

So,

\(\displaystyle A(t) = 24,480 - \frac{66,096,000}{32,401} \cos(t) + \frac{367,200}{32,401} \sin(t) - \frac{726,594,465}{32,401} e^{-t/180}\)

Recall the angle-sum identity for cosine:

\(R \cos(x-\theta) = R \cos(\theta) \cos(x) + R \sin(\theta) \sin(x)\)

so that we can condense the trigonometric terms in A(t). Solve for R and θ :

\(R \cos(\theta) = -\dfrac{66,096,000}{32,401}\)

\(R \sin(\theta) = \dfrac{367,200}{32,401}\)

Recall the Pythagorean identity and definition of tangent,

\(\cos^2(x) + \sin^2(x) = 1\)

\(\tan(x) = \dfrac{\sin(x)}{\cos(x)}\)

Then

\(R^2 \cos^2(\theta) + R^2 \sin^2(\theta) = R^2 = \dfrac{134,835,840,000}{32,401} \implies R = \dfrac{367,200}{\sqrt{32,401}}\)

and

\(\dfrac{R \sin(\theta)}{R \cos(\theta)} = \tan(\theta) = -\dfrac{367,200}{66,096,000} = -\dfrac1{180} \\\\ \implies \theta = -\tan^{-1}\left(\dfrac1{180}\right) = -\cot^{-1}(180)\)

so we can rewrite A(t) as

\(\displaystyle A(t) = 24,480 + \frac{367,200}{\sqrt{32,401}} \cos\left(t + \cot^{-1}(180)\right) - \frac{726,594,465}{32,401} e^{-t/180}\)

As t goes to infinity, the exponential term will converge to zero. Meanwhile the cosine term will oscillate between -1 and 1, so that A(t) will oscillate about the constant level of 24,480 oz between the extreme values of

\(24,480 - \dfrac{267,200}{\sqrt{32,401}} \approx 22,995.6 \,\mathrm{oz}\)

and

\(24,480 + \dfrac{267,200}{\sqrt{32,401}} \approx 25,964.4 \,\mathrm{oz}\)

which is to say, with amplitude

\(2 \times \dfrac{267,200}{\sqrt{32,401}} \approx \mathbf{2,968.84 \,oz}\)

Answer:

  (a)  four and eighty three hundredths with the three repeating

Step-by-step explanation:

The mixed number 4 5/6 will have a repeating decimal fraction, so finite-length decimals will not express it exactly.

  4 5/6 = 4 +5/6 = (4×6)/6 +5/6 = (24+5)/6 = 29/6 . . . . . not 6/29

As you can see from the long division (attached), the decimal fraction will have repeating 3s.

  \(4\dfrac{5}{6}=4.833... =\boxed{4\dfrac{83.\overline{3}}{100}}\)

The exact value of four and five sixths is represented as "six twenty ninths." So, the correct answer is 2.

The value "four and five sixths" is a mixed number. It consists of a whole number part (4) and a fractional part (5/6).

To represent this value exactly, you need to find a fractional form where the numerator (top part) is 5 and the denominator (bottom part) is 6, which is 5/6.

In fractional form, it's represented as 5/6. However, you can also express it as a decimal, which is approximately 0.8333 when rounded to four decimal places.

So, "four and five sixths" can be expressed as:

- Fraction: 5/6

- Decimal (approximate): 0.8333

The other options provided:

- "Four and eighty-three hundredths with the three repeating" does not accurately represent "four and five sixths."

- "4.8" represents "four and eight-tenths," which is different from "four and five sixths."

- "484%" represents 484 percent, which is not the same as "four and five sixths."

Therefore, "six twenty ninths" or 5/6 is the correct representation for "four and five sixths" in fractional form.
