A B C OR D? Correct answer gets braniest!

In this example, the given null hypothesis ( mean) is lies between the 95 % confidence interval so the given null hypothesis is correct.

95% CI = (49.2, 57.0)

Given that:

x= 53.1

SE = 2

[tex]H_o: u = 50\\H_1: u \neq 50[/tex]

We know that 95% confidence interval = X  ± Z < 2 * SE

Now, Z <2 for 95% is 1,96

Therefore, the 95% CI is 53.1 ± 1.96 (2)

= 53.1 ±3.92

95% CI = (49.2, 57.0)

That is fail to reject [tex]H_o[/tex]because the null hypothesis value is inside the 95% confidence interval.

In the Go Math!: Practice Fluency Workbook Grade 6, there are examples that come with the introduction of every new topic. Just by repeating those examples given, you will gain confidence to try your hands on the test questions.

A) As a example, let us take a look at a few questions from Integers.

Question 1:

We need to determine if depositing $85 in a bank account is represented by a positive or a negative number.

Solution:
As the quantity increases, we use a positive number. As the quantity decreases, we use a negative number. A deposit would enhance the account balance, hence the circumstance must be represented with a positive figure +85.


B) An example from Factors and Multiples:
Question: What are the factors of number 5?

Solution:
A number's components are the numbers that split equally into it. To discover a number's factors, consider what pairs of integers multiply to that number.

The δG° for the dissociation of nitrous acid in aqueous solution is 33.2 kJ/mol.

To calculate δG° for the dissociation of nitrous acid in aqueous solution, we can use the equation

δG° = -RTlnK,

where R is the gas constant, T is the temperature in Kelvin, and K is the equilibrium constant for the reaction. Since we are given the value of Ka for the dissociation of nitrous acid, we can use this value as the equilibrium constant in the equation.

Assuming a temperature of 298 K, we can plug in the values into the equation:

δG° = -(8.314 J/mol·K)(298 K)ln(Ka)

When finding confidence intervals for the population mean, we use the following margin of error formulas:

For a large sample size (n > 30) with a known population standard deviation:

Margin of error = z* ( / sqrt(n))

Where z* is the critical value from the standard normal distribution corresponding to the desired level of confidence. For example, for a 95% confidence level, z* = 1.96.

For a small sample size (n < 30) or a large sample size with an unknown population standard deviation:

Margin of error = t* (s / sqrt(n))

Where t* is the critical value from the t-distribution corresponding to the desired level of confidence and degrees of freedom = n - 1), and s is the sample standard deviation.

Note that when the population standard deviation is unknown and estimated using the sample standard deviation, the resulting interval has wider margin of error than when the population standard deviation is known.

When 40.0 ml of 0.150 M [tex]KOH[/tex] is mixed with 20.0 ml of 0.300 M [tex]HBrO[/tex], the pH of the resulting solution is approximately 4.80.

To calculate the pH of the resulting solution when 40.0 mL of 0.150 M [tex]KOH[/tex] is mixed with 20.0 mL of 0.300 M [tex]HBrO[/tex], we need to first determine the concentrations of the ions in solution after the reaction has taken place.

First, let's write the balanced chemical equation for the reaction:

[tex]KOH + HBrO[/tex] → [tex]KBrO + H_2O[/tex]

Since [tex]KOH[/tex] is a strong base and [tex]HBrO[/tex] is a weak acid, we can assume that [tex]KOH[/tex] will react completely with [tex]HBrO[/tex] to form [tex]KBrO[/tex] and water. Therefore, we can use the initial concentrations of [tex]KOH[/tex] and [tex]HBrO[/tex] to determine the concentration of the products.

The amount of [tex]KOH[/tex] in moles is:

0.150 M x 0.0400 L = 0.006 mol [tex]KOH[/tex]

The amount of [tex]HBrO[/tex] in moles is:

0.300 M x 0.0200 L = 0.006 mol [tex]HBrO[/tex]

Since [tex]KOH[/tex] reacts with [tex]HBrO[/tex] in a 1:1 mole ratio, both [tex]KOH[/tex] and [tex]HBrO[/tex] will be completely consumed when the reaction is complete. Therefore, the amount of [tex]KBrO[/tex] formed will also be 0.006 mol.

The total volume of the solution after mixing is:

40.0 mL + 20.0 mL = 60.0 mL = 0.0600 L

The concentration of [tex]KBrO[/tex] is:

0.006 mol / 0.0600 L = 0.100 M

We can use the dissociation constant (Ka) of [tex]HBrO[/tex] to determine the concentration of H3O+ in solution. The Ka expression for [tex]HBrO[/tex] is:

[tex]K_a = \frac{[H_3O^+][BrO^-]}{[HBrO]}[/tex]

We are given that [tex]K_a = 2.5 * 10^{-9[/tex] and that the initial concentration of [tex]HBrO[/tex] is 0.300 M. Let x be the concentration of [tex]H_3O^+[/tex] and [tex]BrO^-[/tex] ions that are formed at equilibrium. Then the concentration of [tex]HBrO[/tex] at equilibrium will be (0.300 - x).

Substituting into the Ka expression, we get:

[tex]2.5 * 10^{-9} = \frac{x^2}{(0.300 - x)}[/tex]

Solving for x using the quadratic formula, we get:

[tex]x = 1.58 * 10^{-5}[/tex] M

Therefore, the concentration of [tex]H_3O^+[/tex] ions in solution is [tex]1.58 * 10^{-5}[/tex] M.

Finally, we can calculate the pH using the equation:

[tex]pH = -log[H_3O^+][/tex]

[tex]pH = -log(1.58 * 10^{-5})[/tex]

pH = 4.80.

HClO (Hypochlorous acid) is a weak acid. The reason is it doesn't completely dissociate or ionize in water. According to theories, only the acids that dissociate completely or almost completely in water are classified as strong acids.

We can use the equilibrium formula for the acid dissociation reaction to compute the relative molar quantities of the species in a 1.0 10-4 M solution of HClO (aq):

[tex]Ka = [H+][ClO^-]/[HClO][/tex]

[H+] = √(Ka[HClO]) = [tex]\sqrt{(3.5 \times 10^{-8} \times 1.0 \times 10^{-4})} = 1.87 \times 10^{-6} M[/tex]
