The addition inequality 37 + x ≥ 42 can be used to determine how much taller William must be to ride the coaster, where x represents the additional height he needs to meet the height requirement.

To write an addition inequality to determine how much taller William must be to ride the coaster, we first need to convert his height to inches. Since he is 3 feet 1 inch tall, his height is (3 x 12) + 1 = 37 inches.

Let x be the amount of additional height William needs to ride the roller coaster. The inequality can be written as:

37 + x ≥ 42

This inequality ensures that William's total height after adding x must be greater than or equal to the required height of 42 inches to ride the roller coaster.

Answer:

X = -5

Step-by-step explanation:

3x - 15 = -30       You want to isolate tha variable

3x= -30+15    Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30

3x= -15    

x= -15÷3   Divide x by 3 in order to get rid of the 3. Do it to the other side

x=-5  

No, because the retailer's claim is not between the lower limit of the mean wait time seconds and the upper limit of OB.

Assume the population standard deviation for wait time is 46 seconds.

Using a 95% confidence interval, we need to test whether this sample supports the retailer's claim or not. Now, the level of significance (α) for a 95% confidence interval is 0.05. So, the critical values for the two-tailed test can be calculated as follows:

Lower critical value, LCV=Z_(α/2)×(σ/√n)=Z_(0.025)×(46/√59)≈2.002

Upper critical value, UCV=Z_(1-α/2)×(σ/√n)=Z_(0.975)×(46/√59)≈-2.002

Now, calculate the margin of error for this test:

Margin of error, E=Z_(α/2)×(σ/√n)=2.002×(46/√59)≈12.35

Thus, the 95% confidence interval for the population mean is (172-12.35) to (172+12.35) or 159.65 to 184.35. Now, we can see that the retailer's claim of 180 seconds does not lie within this confidence interval. Hence, we can conclude that the sample does not support the retailer's claim.

To calculate ΔH°_ing, we need to subtract the sum of enthalpies of products from the sum of enthalpies of reactants. This reaction leads to an (increase) in the entropy of the system.

We know that the given table of thermodynamic data lists ΔH°f values at 298 K. Hence, ΔH°_ing =

[ΔH°f(CaCl2(s))] - [ΔH°f(CaCO3(s)) + 2ΔH°f(HCl(g))] + [ΔH°f(CO2(g)) + ΔH°f(H2O(l))]

The values are as follows: Compound ΔH°f (kJ/mol)CaCl2(s) -795.8  ΔH°_ing = -795.8 + 1391.5 - 679.3

= -83.6 kJ

Calculation of ΔG°_i ax for the reaction To calculate ΔG°_i ax, we need to subtract the product of the molar Gibbs free energy of the reactants and their stoichiometric coefficients from the product of the molar Gibbs free energy of the products and their stoichiometric coefficients.

We can calculate ΔH°ing for the reaction as 319 kJ/mol, but we cannot calculate ΔG° or determine the spontaneity of the reaction without the entropy change (ΔS°) value. The reaction leads to an increase in the entropy of the system.

(a) To calculate ΔH° for the reaction, we need to consider the enthalpy change for each reactant and product. According to the table of thermodynamic data, the enthalpy change for the formation of CaCO3(s) is -1206 kJ/mol, and the enthalpy change for the formation of CaCl2(s) is -795 kJ/mol. Since there are two moles of HCl(g) involved in the reaction, we need to multiply its enthalpy change (-92 kJ/mol) by 2. Now we can calculate ΔH°:

ΔH° = (2 × ΔH° of HCl) + (ΔH° of CaCl2) - (ΔH° of CaCO3)
    = (2 × -92 kJ/mol) + (-795 kJ/mol) - (-1206 kJ/mol)
    = -92 kJ/mol - 795 kJ/mol + 1206 kJ/mol
    = 319 kJ/mol

Therefore, ΔH°ing for the reaction is 319 kJ/mol.

(b) To calculate ΔG° for the reaction, we can use the equation:

ΔG° = ΔH° - TΔS°

However, the table does not provide the entropy change (ΔS°) for the reaction. Therefore, we cannot calculate ΔG° at this time.

(c) Since we do not have the value for ΔG°, we cannot determine whether the reaction is spontaneous or nonspontaneous at 298 K.

(d) The reaction leads to an increase in the entropy of the system. This is because the number of gaseous molecules (CO2 and H2O) is greater in the products than in the reactants (HCl). More gaseous molecules imply greater disorder, thus an increase in entropy.

When angles lie on a straight line, they form a linear pair and add up to 180°. Hence, we can use the following formula to solve for x:z + y + x = 180°.

Given that y = 114° and z = 293°, we can substitute into the formula to get:293° + 114° + x = 180°.

We then simplify by adding like terms and isolating x on one side of the equation: 407° + x = 180°x = 180° - 407°x = -227°.

Since we cannot have a negative value for an angle, the answer is undefined. We can conclude that there is no value for x that satisfies the given conditions.

    12                                   600

    14                                   660

In this relation, the independent variable is time (hours), and the dependent variable is cost ($). The time is the input to the relation, and the cost is the output that is dependent on the input.

We can see that this relation is linear because it has a constant rate of change. The cost increases by $30 for each hour of work, which means that the slope of the line is constant.

The initial value for this relation is $240, which represents the cost of the full landscape plan. The rate of change is $30 per hour, which represents the additional cost for each hour of work. Therefore, the equation for this linear relation is

Cost = 30 x Time + 240

The solution to the initial value problem x'' + 16x = 9f(t) can be expressed as x(t) = h(t) * f(t), where h(t) is the inverse Fourier transform of the transfer function H(ω) = 1/(ω^2 + 16).

1. The convolution theorem allows us to obtain a formula for the solution to the initial value problem x'' + 16x = 9f(t), where x'' represents the second derivative of x with respect to t, and f(t) is a given function. In summary, the solution can be expressed as x(t) = h(t) * f(t), where * denotes the convolution operation and h(t) is the inverse Fourier transform of the transfer function H(ω) = 1/(ω^2 + 16), with ω being the angular frequency.

2. Now, let's explain this in more detail. According to the convolution theorem, the solution to the differential equation x'' + 16x = 9f(t) can be obtained by convolving the input function f(t) with the impulse response of the system, which is given by the inverse Fourier transform of the transfer function H(ω). The transfer function H(ω) represents the frequency response of the system and describes how the system responds to different input frequencies.

3. To find the inverse Fourier transform of H(ω), we first express it as H(ω) = 1/(ω^2 + 16) and then apply the inverse Fourier transform. This yields the impulse response h(t) in the time domain. Once we have h(t), we can convolve it with the input function f(t) using the convolution operation * to obtain the solution x(t).

4. In summary, the convolution theorem allows us to find the solution by convolving the input function with the impulse response of the system, which describes the system's response to different frequencies. This approach provides a formula to solve the given initial value problem.

So you're just trying to find the slop. We're going to choose 2 points to use which are already marked on the graph.

So to find the slope, we have to find (the difference in y) / (the difference in x)
