An important formula from chemistry is PV = nRT. Solve the formula for n.
The solution for n in the chemistry formula is n = PV/RT
How to solve for n in the chemistry formula?From the question, we have the following parameters that can be used in our computation:
Important formula from chemistry is PV = nRT
Write out the formula
So, we have the following representation
PV = nRT
Divide both sides of the equation by R
So, we have the following representation
PV/R = nT
Divide both sides of the equation by T
So, we have the following representation
PV/RT = n
Rewrite the equation as
n = PV/RT
Hence, the solution is n = PV/RT

Answer:
\( \boxed{ \bold{ \huge{ \boxed{ \sf{67}}}}}\)
Step-by-step explanation:
Given,
UV = 19
VW = 4x - 20
UW = 6x - 35
To find : value of UW
First, finding the value of x
Create an equation and solve for x
\( \sf{UV + VW = UW}\)
\( \longrightarrow{ \sf{19 + 4x - 20 = 6x - 35}}\)
\( \longrightarrow{ \sf{ - 1 + 4x = 6x - 35}}\)
\( \longrightarrow{ \sf{4x - 6x = - 35 + 1}}\)
\( \longrightarrow{ \sf{ - 2x = - 34}}\)
\( \longrightarrow{ \sf{ \frac{ - 2x}{ - 2} = \frac{ - 34}{ - 2}}} \)
\( \longrightarrow{ \sf{x = 17}}\)
Value of x = 17
Replacing / Substituting the value of x in 6x - 35 in order to find the value of UW
\( \sf{UW = 6x - 35 = 6 \times 17 - 35 = 67}\)
UW = 67

Different types of bees are very similar in appearance. Statistical analysis of certain measurements, like wing width, can be used to distinguish one kind of bee from another.
The wing width for a specific type of honeybee is approximately normally distributed with a mean of 2.82 millimeters (mm). A random sample of 10 bees is taken from a hive and the wing widths are given below.
Wing Width Measurements (mm)
2.88
2.83
2.91
2.83
2.94
2.87
2.80
2.80
2.83
2.88
A Hypothesis test is to be conducted to determine whether or not bees from the hive is the same as the specific type of honeybee having a mean wing width of 2.82 mm.
The conclusion is that the evidence is not sufficient to reject the claim that bees from the hive is the same as the specific type of honeybee having a mean wing width of 2.82 mm.
How to calculate the p-value of the sample distribution?We are given the following;
Population mean; μ = 2.82 mm
Sample size; x' = 10
Thus;
Sample mean; x' = (2.88 + 2.83 + 2.91 + 2.83 + 2.94 + 2.87 + 2.80 + 2.80 + 2.83 + 2.88)/10
x' = 2.857
Using online calculator, the standard deviation is; s = 0.0467
Now, the hypotheses are defined as;
Null Hypothesis; H₀; μ = 2.82 mm
Alternative Hypothesis; Hₐ; μ ≠ 2.82 mm
The formula for the z-score of the distribution is;
z = (x' - μ)/s
Thus;
z = (2.857 - 2.82)/0.0467
z = 0.792
From online p-value from z-score calculator, we can say that;
p-value = 0.4284
This is greater than the significance value of 0.05 and as such we will conclude that we fail to reject the null hypothesis.

Dani wants to make a punch using orange juice. The recipe calls for 11 cups of orange juice. How many pints is that? (1 cup = 0.5 pints)
Answer:
5.5 pints
Step-by-step explanation:
This answer is determined very easily. Basically, since we already know that we need 11 cups and that 1 cup is 0.5 pints, all that must be done is that the 11 cups must be multiplied by the 0.5 pints. This allows us to get the number of pints 11 cups is equal to, 5.5 pints.

E). $1014 per person
Step-by-step explanation:
The data of the cost

A). Mean cost per game
Mean = (266+201+197+188+162)/5

Mean = 202.8
Mean cost per game= $202.8
B) range = highest value- Lowest value
Range= 266-162
Range= $104
C) variance= ((266-202.8)²+(201-202.8)²+(197-202.8)²+(188-202.8)²+(162-202.8)²)/5
Variance=(3994.24+3.24+33.64+219.04+1664.64)/5

Data is collected to compare two different types of batteries. We measure the time to failure of 12 batteries of each type. Battery A: . Battery B: . Assume equal variances and that we calculated . Perform a .05 level test to determine if Battery B outlasts Battery A by more than 2 hours.
Using the t-distribution, it is found that since the test statistic is greater than the critical value for the right-tailed test, it is found that there is enough evidence to conclude that Battery B outlasts Battery A by more than 2 hours.
At the null hypothesis, it is tested if it does not outlast by more than 2 hours, that is, the subtraction is not more than 2:
\(H_0: \mu_B - mu_A \leq 2\)
At the alternative hypothesis, it is tested if it outlasts by more than 2 hours, that is:
\(H_1: \mu_B - \mu_A > 2\)
The sample means are: \(\mu_A = 8.65, \mu_B = 11.23\) The standard deviations for the samples are \(s_A = s_B = 0.67\)Hence, the standard errors are:
\(s_{Ea} = S_{Eb} = \frac{0.67}{\sqrt{12}} = 0.1934\)
The distribution of the difference has mean and standard deviation given by:
\(\overline{x} = \mu_B - \mu_A = 11.23 - 8.65 = 2.58\)
\(s = \sqrt{s_{Ea}^2 + s_{Eb}^2} = \sqrt{0.1934^2 + 0.1934^2} = 0.2735\)
The test statistic is given by:
\(t = \frac{\overline{x} - \mu}{s}\)
In which \(\mu = 2\) is the value tested at the hypothesis.
Hence:
\(t = \frac{\overline{x} - \mu}{s}\)
\(t = \frac{2.58 - 2}{0.2735}\)
\(t = 2.12\)
The critical value for a right-tailed test, as we are testing if the subtraction is greater than a value, with a 0.05 significance level and 12 + 12 - 2 = 22 df is given by \(t^{\ast} = 1.71\)
Since the test statistic is greater than the critical value for the right-tailed test, it is found that there is enough evidence to conclude that Battery B outlasts Battery A by more than 2 hours.

a) The mean of the data-set is of 2.
b) The range of the data-set is of 4 units, which is of around 4.3 MADs.
How to obtain the mean of a data-set?The mean of a data-set is obtained as the sum of all observations in the data-set divided by the number of observations in the data-set, which is also called the cardinality of the data-set.
The dot plot shows how often each observation appears in the data-set, hence the mean of the data-set is obtained as follows:
Mean = (1 x 0 + 5 x 1 + 3 x 2 + 5 x 3 + 1 x 4)/(1 + 5 + 3 + 5 + 1)
Mean = 2.
The range is the difference between the largest observation and the smallest, hence:
4 - 0 = 4.
4/0.93 = 4.3 MADs.

A.
Yes, Yoshi's justifications fit.
B.
No; justification 2 should be “Multiplication property of equality.”
C.
No; justification 3 should be “Commutative property of multiplication.”
D.
No; justification 5 should be “Inverse property of multiplication.”
What Yoshi uses is the multiplication property of equality, so the correct option is B.
Yoshi’s justifications fit with the corresponding step?
The step that Yoshi did is:
(1/2)*s = 112
s = 112*(2/1) = 224.
What Yoshi does there is multiplicating both sides by the inverse of (1/2), so it is cancelled in the left side and the variable is isolated.

Step-by-step explanation:
Solve the initial-value problem
3y′ + (1 + 8x^7)y = (e^(-x^8))/y^2, y(0) = 1.
Note that this is a Bernoulli differential equation.
Write as a function of x.
Answer:
Step-by-step explanation:
To solve this initial value problem, we can use the Bernoulli differential equation technique:
Divide both sides of the equation by y^3 to obtain:
3y^(-2) y' + (1 + 8x^7)/y^3 = e^(-x^8)/y^5
Let z = y^(-1), then we can rewrite the equation as:
-3z' + (1 + 8x^7)z = e^(-x^8)
This is now a linear differential equation with an integrating factor of:
μ(x) = e^(∫(1 + 8x^7) dx) = e^(x + 4x^8)
Multiply both sides of the equation by the integrating factor to obtain:
-3(e^(x + 4x^8) z)' = e^(x - x^8)
Integrate both sides with respect to x to get:
-e^(x + 4x^8) z = ∫e^(x - x^8) dx + C
where C is a constant of integration.
Solve for z to get:
z = -1/e^(x + 4x^8) ∫e^(x - x^8) dx - C/e^(x + 4x^8)
Substituting z = y^(-1), we get:
y(x) = (C - ∫e^(x - x^8) dx)/e^(x + 4x^8)
Using the initial condition y(0) = 1, we can solve for C:
y(0) = (C - ∫e^(0 - 0^8) dx)/e^(0 + 4(0^8)) = C/1 = 1
So, C = 1.
Substituting C = 1, we get the solution:
y(x) = (1 - ∫e^(x - x^8) dx)/e^(x + 4x^8)
Therefore, the solution to the initial-value problem is:
y(x) = (1 - ∫e^(x - x^8) dx)/e^(x + 4x^8)
As an explicit function of x, the integral term cannot be simplified any further.
