You have to calculate the subtraction of two mixed numbers.
\(2\frac{1}{8}-1\frac{7}{8}\)To subtract two mixed numbers, the first step is to express the said numbers as improper fractions.
Let's start with 2 1/8. First, divide the whole number by 1 to express it as a fraction and add 1/8 to it:
\(\frac{2}{1}+\frac{1}{8}\)Next, multiply the fraction 2/1 by 8 (both numerator and denominator) to express it with the same denominator as the fraction 1/8:
\(\begin{gathered} \frac{2\cdot8}{1\cdot8}+\frac{1}{8} \\ \frac{16}{8}+\frac{1}{8} \end{gathered}\)Finally, add both fractions:
\(\frac{16+1}{8}=\frac{17}{8}\)Now we have to express the mixed number1 7/8 as a fraction. As before, the first step is to divide the whole number by 1 to express it as a fraction and add 7/8:
\(\frac{1}{1}+\frac{7}{8}\)To add both fractions they must be expressed with the same denominator, so multiply the first fraction by 8, to express it with denominator 8:
\(\begin{gathered} \frac{1\cdot8}{1\cdot8}+\frac{7}{8} \\ \frac{8}{8}+\frac{7}{8} \end{gathered}\)Finally, add both fractions:
\(\frac{8+7}{8}=\frac{15}{8}\)Now that both mixed numbers are expressed as improper fractions, we can proceed to subtract them:
\(2\frac{1}{8}-1\frac{7}{8}=\frac{17}{8}-\frac{15}{8}\)To add/subtract two fractions, they must be expressed with the same denominator. The denominator of both fractions is "8" so we can subtract the fractions.
You just have to subtract the numerators of the fractions:
\(\frac{17}{8}-\frac{15}{8}=\frac{17-15}{8}=\frac{2}{8}\)The result of the subtraction is 2/8
This fraction is not expressed as its simplest form, both "2" and "8" are divisible by 2, you can simplify this fraction by dividing both the numerator and denominator by 2:
\(\frac{2\div2}{8\div2}=\frac{1}{4}\)The simplified result of the subtraction is 1/4

a) No, adding all three sides does not add up to the correct measurements.
b) No, because two sides add up to less than the third one.
c) No, because two sides add up to more than the third one.
d) Yes, because two sides add up to less than the third one.
e) Yes, because two sides add up to more than the third one.
Answers
Answer:
e) Yes, because two sides add up to more than the third one.-------------------------
Apply the Triangle Inequality Theorem.
It states that:
For a triangle to exist, the sum of the lengths of any two sides must be greater than the length of the third side.We'll take the sum of two shortest sides and compare with the longest:
4.5 + 5.6 = 10.1 > 10It confirms the theorem, without testing the other two sides (which is obvious) so the answer is yes.
The matching answer choice is e).

Answers
Step-by-step explanation:
it seems you solved the tricky part yourself already.
just to be sure, let's do the first derivative here again.
the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...
f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =
= 3t⁴ + 18t³ + 24t² + 18t + 21
f'(t) = 12t³ + 54t² + 48t + 18
and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).
we simply put the input number (2) at every place of the input variable (t).
so,
f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =
= 426

A couple plans to purchase a house. The bank requires a 20% down payment on the $240,000 house. The couple will finance the rest of the cost with a fixed- rate mortgage at 8.5% annual interest with monthly payments over 30 years.
Complete the parts below. Do not round any intermediate computations. Round your final answers to the nearest cent if necessary. If necessary, refer to the list of financial formulas.
(a) Find the required down payment.
(b) Find the amount of the mortgage.
(c) Find the monthly payment.
Answers
(A) The required down payment is $48,000.
(B) The amount of the mortgage is $192,000.
(C) Monthly payment = $192,000 * (0.085/12) * (1 + (0.085/12))^(3012) / (((1 + (0.085/12))^(3012)) - 1)
(a) To find the required down payment, we need to calculate 20% of the house price.
Down payment = 20% of $240,000
Down payment = 0.2 * $240,000
Down payment = $48,000
The required down payment is $48,000.
(b) The amount of the mortgage is equal to the total cost of the house minus the down payment.
Mortgage amount = Total cost of the house - Down payment
Mortgage amount = $240,000 - $48,000
Mortgage amount = $192,000
The amount of the mortgage is $192,000.
(c) To find the monthly payment for the mortgage, we can use the formula for the monthly payment on a fixed-rate mortgage:
Monthly payment = P * r * (1 + r)^n / ((1 + r)^n - 1)
Where:
P = Principal amount (mortgage amount)
r = Monthly interest rate (8.5% annual interest divided by 12 months and converted to a decimal)
n = Total number of monthly payments (30 years multiplied by 12 months)
Monthly payment = $192,000 * (0.085/12) * (1 + (0.085/12))^(3012) / (((1 + (0.085/12))^(3012)) - 1)
Using this formula and performing the calculation will give you the monthly payment amount.

The hypotenuse of a right triangle is three times the length of one of its legs. The length of the other leg is four feet. Find the lengths of the three sides of the triangle. For non-integer answer(s), round your answer(s) to the nearest tenth.
Answers
Hello!
It is given information that this triangle is a right triangle, meaning that the Pythagorean Theorem can apply here.
\(a^2+b^2=c^2\)
We can set the length of a leg as an unknown variable \(x\).
\(x^2+4^2=(3x)^2\)
Remember that it is the whole \(3x\) term being squared, meaning that it'll simplify to \(9x^2\), not \(3x^2\).
\(x^2+16=9x^2\)
\(8x^2=16\)
\(x^2=2\)
\(x=\sqrt{2}\)
This means we can plug back in to find the sides.
The hypotenuse would be \(3\sqrt{2}\), or 4.2.
And the legs would be 1.4 and 4, respectively.
Hope this helps!

x = 7
Step-by-step explanation:
Triangle = 180˚ so
8x =56 , because x is 7. I know this bc it is a little bit more than 53 (you can tell just by looking at the triangle.)and it is impossible for it to be higher than 56, because angle c is more than 56. And I also checked it, so it is right.
e + d + c = 180
53 + 56 + c = 180
180 - 109 = 71 so
71 = c

30% of Elm trees have a certain disease. If you sample 80 elm trees, what is the probability that less than 20 trees have the disease?
Answers
The probability that less than 20 trees have the disease is; 0.135
How to find the Probability?
The formula for binomial probability is;
P(X = x) = ⁿCₓ * pˣ * (1 - p)⁽ⁿ ⁻ ˣ⁾
We are told that 30% of Elm trees have a certain disease. Thus;
p = 30% = 0.3
n = 80
x = 20
Thus, probability that less than 20 trees have the disease is;
P(X < 20) = P(X = 0) + P(X = 1) + P(X = 2) + ....... + P(X = 19)
Using a binomial probability calculator online gives us;
P(X < 20) = 0.135

An inverse trigonometric function for the angle θ as a function of x is θ = sin⁻¹((x + 3)/5).
An inverse trigonometric function for the angle θ as a function of x is θ = tan⁻¹(x/2).
How to determine the value of θ?In order to determine the value of θ with respect to x, we would apply basic trigonometry. From the information provided about this right angled triangle, we can logically deduce the following parameters:
Opposite side (Opp) = x + 3
Hypotenuse (Hyp) = 5.
Therefore, we would use the sine trigonometry to determine the value of θ as follows:
Sinθ = Opposite side/Hypotenuse
Sinθ = (x + 3)/5
θ = sin⁻¹((x + 3)/5)
For the second right angled triangle, we have:
Tan(θ) = Opposite side/Adjacent side
θ = tan⁻¹(x/2).

A manufacturer of running shoes knows that the average lifetime for a particular model of shoes is 15 months. Someone in the research and development division of the shoe company claims to have developed a longer lasting product. This new product was worn by 25 individuals and lasted on average for 17 months. The variability of the original shoe is estimated based on the standard deviation of the new group which is 5.5 months. Is the designer's claim of a better shoe supported by the trial results?
Answers
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.
Step-by-step explanation:
From the question we are told that
The population mean is \(\mu = 15 \ months\)
The sample size is n = 25
The sample mean is \(\= x = 17 \ months\)
The standard deviation is \(s = 5.5 \ months\)
Let assume the level of significance of this test is \(\alpha = 0.05\)
The null hypothesis is \(H_o : \mu = 15\)
The alternative hypothesis is \(H_a : \mu > 17\)
Generally the degree of freedom is mathematically represented as
\(df = n -1\)
=> \(df = 25 -1\)
=> \(df = 24\)
Generally the test statistics is mathematically represented as
\(t = \frac{\= x- \mu }{\frac{s}{\sqrt{n} } }\)
=> \(t = \frac{ 17 - 15 }{\frac{5.5}{\sqrt{25} } }\)
=> \(t = 1.8182\)
Generally from the student t distribution table the probability of obtaining \(t = 1.8182\) to the right of the curve at a degree of freedom of \(df = 24\) is
\(p-value = P(t > 0.18182 ) = 0.4286\)
From the value obtained we see that \(p-value > \alpha\) hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.

The quantitative analysis also focused on finding critical statistical values like mean, median, mode, standard deviation, variance, and minimum/maximum variables. The results of the data are summarized in Table 2. Revenue Passenger Miles (RPM) mean is 6,624,897, the median is 6,522,230, and mode is NONE. The minimum is 5,208,159 and the maximum is 8,277,155. The standard deviation is 720,158.571, and the variance is 518,628,367,282.42.
Load Factors (LF) mean is 82.934, the median is 83.355, and mode is 84.56. The minimum is 74.91, and the maximum is 89.94. The standard deviation is 3.972, and the variance is 15.762. The Available Seat Miles (ASM) mean is 7,984,735, the median is 7,753,372, and mode is NONE. The minimum is 6,734,620, and the maximum is 9,424,489. The standard deviation is 744,469.8849, and the variance is 554,235,409,510.06.Figure 1 above displays the performance of American Airlines (Domestic).
The mean RPM is 7,984,735, and the linear regression line is y = 50584x - 2.53E+8. The linear regression line indicates a positive relationship between RPM and year, with a coefficient of determination, R² = 0.6806. A coefficient of determination indicates the proportion of the variance in the dependent variable that is predictable from the independent variable. Therefore, 68.06% of the variance in RPM is predictable from the year. A one-way ANOVA analysis of variance test was conducted to determine the equality of means of three groups of variables; RPM, ASM, and LF. The null hypothesis is that the means of RPM, ASM, and LF are equal.
The alternative hypothesis is that the means of RPM, ASM, and LF are not equal. The level of significance is 0.05. The ANOVA results indicate that there is a significant difference in means of RPM, ASM, and LF (F = 17335.276, p < 0.05). Furthermore, a post-hoc Tukey's test was conducted to determine which variable means differ significantly. The test indicates that RPM, ASM, and LF means differ significantly.
The skewness test was conducted to determine the symmetry of the distribution of RPM, ASM, and LF. The test indicates that the distribution of RPM, ASM, and LF is not symmetrical (Skewness > 0).
Additionally, the z-statistic test was conducted to determine the deviation of RPM, ASM, and LF from the mean. The test indicates that RPM, ASM, and LF significantly deviate from the mean.

1a. The percentage total return is -19.56%
1b. The dividend yield is 2.42%.
1c. The capital gains yield is -21.98%.
2a. The arithmetic average annual return on large-company stocks in nominal terms is 14.5%.
2b. The arithmetic average annual return on large-company stocks in real terms is 9.67%.
3a. The real return on long-term government bonds is 3.195%
3b. The real return on long-term corporate bonds is 3.291%
How to calculate the percentage total return?In Financial accounting, the percentage total return (P) can be calculated by using this formula;
P = [(Ending price - Initial price) + Dividend] ÷ Initial price
P = [(71 - 91) + 2.20] ÷ 91
P = -0.1956 or -19.56%
1b. For the dividend yield, we have:
Dividend yield = Dividend ÷ Initial price
Dividend yield = 2.20 ÷ 91
Dividend yield = 0.0242 or 2.42%
1c. For capital gains yield, we have:
Capital gains yield = (Ending price - Initial price) ÷ Initial price
Capital gains yield = (71 - 91) ÷ 91
Capital gains yield = -0.2198 or -21.98%.
Part 2.
a. The arithmetic average of annual return on large-company stocks in nominal terms is equal to 14.5%.
b. For arithmetic average annual return in real terms, we have:
(1 + 0.145) = (1 + r)(1 + 0.044)
r = (1.145/1.044) - 1
r = 9.67%
Part 3.
a. For real return on the long-term government bonds, we would apply Fisher equation:
(1 + i) = (1 + r)(1 + h)
Where:
i is the nominal interest rate.r is the real interest rate.h is the inflation rate.(1 + 0.066) = (1 + r)(1 + 0.033)
1 + r = 1.066/1.033
r = 3.195%
b. For real return on long-term corporate bonds:
(1 + 0.067) = (1 + r)(1 + 0.033)
1 + r = 1.067/1.033
r = 3.291%

The solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11). The system has exactly one solution.
Let's solve the system of linear equations correctly.
The given system of linear equations is:
x = y + 3z = 6
x - 2y = 5
2x - 2y + 5z = 9
To determine the number of solutions, we can analyze the system using the method of elimination or substitution. Let's use the method of elimination:
From equation 1, we have:
x = y + 3z
Substituting this value of x in equation 2:
(y + 3z) - 2y = 5
y + 3z - 2y = 5
-z + 3z = 5 - y
2z = 5 - y
Now, let's substitute the value of x in equation 3:
2(y + 3z) - 2y + 5z = 9
2y + 6z - 2y + 5z = 9
11z = 9
Simplifying the equation, we find:
z = 9/11
Now, substituting this value of z back into the equation 2z = 5 - y, we get:
2(9/11) = 5 - y
18/11 = 5 - y
18/11 - 5 = -y
18/11 - 55/11 = -y
-37/11 = -y
y = 37/11
Finally, we can substitute the values of y and z into equation 1 to find the value of x:
x = y + 3z
x = 37/11 + 3(9/11)
x = 37/11 + 27/11
x = 64/11
Therefore, the solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11).
The system has exactly one solution.
