The value of s, considering that quadrilateral DEFG is a rhombus, is given as follows:
s = 55.
How to obtain the value of s?To obtain the value of S, we must consider triangle CED, and the fact the sum of the measures of the internal angles of a triangle is of 180º.
The measures of the internal angles of triangle CED are given as follows:
<C = 90º. (the diagonals of the rhombus are perpendicular).<D = 60º. (the center of the rhombus is a bisection).<E = s - 25.As the sum of the measures of the internal angles of a triangle is of 180º, the measure of angle E is given as follows:
90 + 60 + <E = 180
150 + <E = 180
<E = 30º.
As <E = s - 25, the value of s is obtained as follows:
s - 25 = 30
s = 30 + 25

By solving an inequality we will see that for 7 movies (or more) the first store is a better deal.
What is the minimum number of movies so the first store is better?We know that the first store charges $12.50 as a fixed cost plus $1.50 per movie rented, so if you rent x movies, the total cost is:
c(x) = $12.50 + $1.50*x
While the second store charges $3.50 per movie, then the cost for renting x movies here is:
h(x) = $3.50*x
We want to find the minimum value x such that c(x) < h(x), then we need to solve the inequality:
$12.50 + $1.50*x < $3.50*x
$12.50 < $3.50*x - $1.50*x
$12.50 < $2.00*x
$12.50/$2.00 < x

The equation of line p is y = ax + b then y = -2ax + b + 3 could be only the equation of line q out of the given options.
Therefore, the answer is C) y = -2ax + b + 3.
The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. So in case of line p, a is the slope and b is the y-intercept. Let equation of q by y = m'x + b'.
From the figure it is evident that line p has a positive slope while line q has a negative slope. So slope of q is negative of slope of line q multiplied by a positive constant, say c, then
m' = -2ac
From figure we can observe that y-intercept of p is 0 and q has a positive y-intercept, so
b' = b + k, k is a positive constant
So equation of q is y = -2acx + b + k, where c and k are positive constants. So only option C is of this format.

In this setting, explain how bias may have been introduced based on the way the question was worded and suggest how it could have been worded differently to avoid that bias.
Based on the provided information, a) bias is introduced through convenience sampling there could be specific variable associated with the first hundred students. It can be avoided by simple random sampling. b) bias is introduced through wording as it includes a negative consequence. It can be avoided by just asking for an opinion without any associated reasoning or consequences.
Bias refers to a deviation of feedback which is based on certain influences by the surveyor and respondent. Sampling bias or selection bias refers to a type of bias in which a researcher gathers a sample of respondents for a questionnaire that does not accurately represent the population. Survey bias refers to the way the question is phrased or formatted, leading people to choose a certain answer instead of another. In the given case,
a) A bias may have been introduced based on the way the convenience sample was selected as there could be specific variable associated with each of the first hundred students that walk into the dining room. The first hundred students could possibly like the food and that is the reason why they come early to the dining room. Selecting students at the dining room may also exclude the students who dislike the food and choose to eat elsewhere. A simple random sample can help avoid this bias. By randomly selecting students at the university campus would provide a more inclusive and true representation of the population.
b) A bias may have been introduced based on the way the question is worded is to maintain the current meal plan as it presents a negative consequence to introducing a new meal plan. It states that a new meal plan would result in more cost. In order to avoid bias, the survey should ask students opinion about the food without introducing any external reasoning.

leo reads 12 pages in 1/4 hour. what is the unit rate for pages per hour? For hours per page?
Answer:
3
Step-by-step explanation:
to find the rate you have to multiply the fraction so...
12 (the pages) times 1/4 (the hour) you get 3
Answer:
48 pages per hour; 3 hours per page
Step-by-step explanation:
A). You can find the unit rate for pages per hour by first multiplying the hours by its reciprocal, 4, which essentially becomes 1 hour and what you do to one side must be done to the other side, so multiplying 12 by 4 gets you 48 pages. Therefore, Leo reads 48 pages per hour.
B). To find hours per page, you do the same thing, except that this time, you divide 12 on each side because you are trying to find the hours per page. 12 pages divided by 12 gets you 1 page and dividing 1/4 by 12 is the same thing as multiplying 1/4 by 12 since when dividing fractions with another fraction, the method is to use the reciprocal of the second fraction (in this case, 1/12 becomes 12) and you change the sign to its inverse and you simplify. A helpful acronym you can use is this. KEEP IT, CHANGE IT, FLIP IT . You keep the first fraction as it is, change the sign to its inverse, and flip the second fraction (virtually, the reciprocal). Therefore, in this case, it becomes 1/4 times 12 and 12 divided by 4 is nothing but 3.
Thus, Leo takes 3 hours to read each page.
Hope this helped! :D
Using the substitution u(x) = y + x, solve the differential equation dy/dx = (y + x)^2 .
The solution to the differential equation is y = 2x/(y + 2x), which can be interpreted as y is equal to twice x divided by y plus twice x.
du/dx = 2(y + x)
Integrating both sides, we get
∫du/2(y + x) = ∫dx
1/2 ∫u du = x + C
(1/2)u^2 = x + C
(1/2)(y + x)^2 = x + C
y^2 + 2xy + x^2 = 2x + C
y^2 + 2xy = 2x + C - x^2
y^2 + 2xy = 2x + C - x^2
y^2 + 2xy + C = 2x + C
y^2 + 2xy + C = 2x + C
y^2 + 2xy = 2x
y(y + 2x) = 2x
y = 2x/(y + 2x)
y = 2x/(y + 2x) y = 2x/(y + 2x), which can be interpreted as y is equal to twice x divided by y plus twice x.

What is the product of the complex numbers (- 3i 4 and 3i 4?
The product of these two complex numbers is calculated by multiplying the real numbers and imaginary parts separately and then combining them, resulting in -25.
Step 1: Multiply the real parts: (-3i * 3i = -9i^2
Step 2: Multiply the imaginary parts: 4 * 4 = 16
Step 3: Combine the results: -9i^2 + 16 = -25
(-3i * 3i) + (4 * 4) = -9i^2 + 16 = -25
Complex numbers consist of two parts - a real part and an imaginary part. To find the product of two complex numbers, both the real and imaginary parts must be multiplied separately, and then the results combined. In this example, (-3i 4 and 3i 4), the real parts are multiplied together to get -9i2. The imaginary parts are multiplied together to get 16. These results are then combined to get the product of the complex numbers, which is -25. To complete the calculation, we must also take into account that the imaginary part is always multiplied by the coefficient i. This means that the result of the real part multiplication is -9i2, not just -9.

By using Pythagorean theorem to find the length of the hypotenuse, we get the answer as hypotenuse of 115
What is Pythagorean triple?A Pythagorean triple is a set of three positive integers a, b, and c that satisfy the equation a^2 + b^2 = c^2, where c is the length of the hypotenuse and a and b are the lengths of the legs of the right triangle.
What is hypotenuse?In a right triangle, the hypotenuse is the side that is opposite the right angle. It is the longest side of the triangle and it is always opposite the 90-degree angle. The other two sides of the right triangle are called the legs, and they form the right angle.
we can use the Pythagorean theorem to find the length of the hypotenuse:
a^2 + b^2 = c^2
82^2 + 80^2 = c^2
6724 + 6400 = c^2
c = √(6724 + 6400) = √13124
c = 114.74
Since all three sides of the triangle have to be integers and the hypotenuse is the one that should have the largest value, we can round the value of c up to 115

P, is the proportion of smokers in the population who have had a drink in the past week and P is the
corresponding proportion of non-smokers, then a test of the hypotheses H, P, -P-0 against the two-sided alternative produces a test statistic of z=3.07 and a P-value of 0.002.

e) The test statistic and P-value for the chi-square test of homogeneity would be -1.75 and 0.004, respectively.
A chi-square test of homogeneity is a useful tool for comparing two or more categorical variables. In this case, the two variables are smoking (smokers and non-smokers) and alcohol consumption (those who had consumed alcohol in the past week and those who hadn't).
The chi-square statistic is calculated by finding the difference between the observed and expected frequencies of the two groups and squaring it. The expected frequencies are found by multiplying the sample size by the overall probability of success (in this case, drinking alcohol).
The P-value is then calculated based on the chi-square statistic and the degrees of freedom (in this case, one). In this case, the chi-square statistic is -1.75 and the P-value is 0.004.

Colinda has just purchased her first home for $125,000. She put down a 20 percent down payment of $25,000 and took out a 5 percent 30-year mortgage for the rest. Her mortgage payment is $536. 82 per month. How much of her first monthly mortgage payment is amortization?.
Amortization makes up $120.15 of colinda's first monthly mortgage payment.
We must first determine the total amount of Colinda's mortgage in order to determine the amount of her first monthly mortgage payment, which is amortization. Her 20% down payment of $25,000 reduced the mortgage balance to $100,000 ($125,000 – $25,000).
The 30-year term and 5% interest rate on the mortgage result in a $536.82 monthly payment. The portion of the mortgage payment designated for amortization is the sum that is used to pay off the loan's principle; the remainder is used to cover interest.
We can use the following formula to determine the amortization part of the mortgage payment:
Amortization = (Mortgage Payment) - (Interest Payment)
Where:
The mortgage payment ($536.72) is made each month.
Monthly interest payments are computed using the following formula: (Amount of Mortgage) (12%) Interest Rate
When we enter the values, we obtain:
Amortization is calculated as ($536.72) - ($100,000) * (0.05/12)
$536.82 - $416.67 is the amortization.
Amount amortized : $120.15
