Given the equation startfraction 2 x 2 over y endfraction = 4 w 2 what is the value of x? x = y w y minus 1 x = 2 y w y minus 1 x = 2 y w y minus 2 x = 4 y w 2 y minus 2
The value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.
According to the given question.
We have an equation
2x + 2/y = 4w + 2
Since, we have to find the value of x for the given equation
2x + 2/y = 4w + 2
Thereofore,
2x + 2/y = 4w + 2
⇒ 2(x + 1)/y = 2(2w + 1) (taking 2 common from both the sides)
⇒ (x + 1)/y = 2w + 1
⇒ (x + 1) = y(2w + 1) (multiplying both the sides by y)
⇒ x + 1 = 2yw + y
⇒ x = 2yw + y - 1 ( subtracting 1 both the sides)
Hence, the value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.

The number of positive and negative real roots of the function
x³ - x² - x - 5 are 1 and 2 respectively.
What is Descartes' Rule?
Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeros in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients.
Number of positive real roots of f(x) ≤ Number of sign changes f(x)
Number of negative roots of f(x) ≤ Number of sign changes of f(-x)
According to the given questions:
The given polynomial function f(x) = x³ - x² - x - 5
We can observe the number of sign changes in the coefficients
The sign changes only once
hence there is one positive real root
Now, f(-x) = -x³ + x² - x + 5
Clearly sign changes 2 times evenly
Therefore the function has 2 negative real roots

Answer:
AOB seems to be the same as DOE, which means DOE is equal to 40 degrees as well. And if DOF is 120, and DOE is inside of it, you would subtract 40 from 120, which is 80. And since that area is also the same as BOC, it would mean that BOC is equal to 80 as well.
So since we have those current angles, we have to add them up (40+40+80+80) which is equal to 240 degrees. Since there is 360 degrees in a circle, you would then subtract 240 from 360 to find the last answers, which equals 120. However since there are two angles left, it means we would split that 120, which equals 60. Now we add all the answers together (40+40+80+80+60+60=360)

The amount of simple interest earned on a $970 investment after 2 years at a semi-annual interest rate of 2% is $19.40.
How is simple interest determined?We may use the simple interest formula, which is: to determine how much simple interest was gained on a $970 investment after two years at a 2% semi-annual interest rate.
I = P * r * t
where I equals interest accrued
Principal (P) (the initial investment)
r = annual interest rate (in decimal form)
T is the duration in years.
As the interest rate is stated as a semi-annual rate, we must double the time period by two and divide the interest rate by two to convert them to years.
When we enter the specified values into the formula, we obtain:
I = $970 * 0.02/2 * 2 = $19.40

Suppose we obtain a sample proportion using a sample of size 100. If we want to obtain another sample proportion from the same population, but with standard deviation one-half of what it was for a sample of size 100, what should the sample size be
The standard deviation of a sample proportion is given by the formula:
σ = sqrt((p * (1 - p)) / n)
where σ is the standard deviation, p is the sample proportion, and n is the sample size.
If we want the standard deviation to be one-half of what it was for a sample of size 100, we can write the following equation:
(sqrt((p * (1 - p)) / n)) / 2 = sqrt((p * (1 - p)) / 100)
To simplify the equation, we can square both sides:
((p * (1 - p)) / n^2) / 4 = (p * (1 - p)) / 100
Simplifying further:
100 * n^2 = 4 * 1
n^2 = (4 * 1) / 100
n^2 = 0.04
Taking the square root of both sides:
n = sqrt(0.04)
n = 0.2
Therefore, the sample size should be 0.2. However, since the sample size must be a positive integer, we round it up to the nearest whole number. Therefore, the sample size should be 1.

how many pounds of sunflower seed does the mixture contain?
Explanation
In the question, we are given that the millet seeds and the sunflowers seed are packaged in 5 pounds back.
We can assume that the pounds of millet seeds be x and the pounds of sunflower seeds be y. We can therefore create the equation;
\(x+y=5----(1)\)Next, we know that a pound of sunflower seed cost $1.75 and a pound of millet seed cost $2.50 and the mixture is sold for $11.60. This will imply;
\(2.50x+1.75y=11.60----(2)\)We will then solve the above equation simultaneously.
\(\begin{gathered} \text{Isolate x for x+y =5} \\ x=5-y-----(3) \end{gathered}\)Insert equation 3 in equation 2
\(\begin{gathered} 2.50(5-y)+1.75y=11.60 \\ 12.5-0.75y=11.6 \\ 0.75y=12.5-11.6 \\ 0.75y=0.9 \\ y=\frac{0.9}{0.75} \\ y=1.2 \end{gathered}\)Since the weight of the sunflower seed is represented by y, therefore the answer is;

a cell phone manufacturer inspects the video display on each color phone to verify that the screen can display all colors with the brilliance their customers have come to expect. each phone is turned on, run through a self-test procedure, and classified as either acceptable or unacceptable based on test performance. based on historical data, the manufacturer produces 0.2 percent defective displays. if they inspect 4000 phones each day for the next 10 days, what are the upper and lower control limits for their control chart if their sample mean mirrors their historical process average?
The upper control limit for the control chart is 12.7433 and the lower control limit is 3.2567.
Assuming that the manufacturer's inspection process is a binomial process, we can use the normal approximation to the binomial distribution to calculate the control limits for their control chart. The mean of the binomial distribution is given by:
μ = np
where n is the sample size (4000 phones per day), and p is the probability of a defective display (0.002). The standard deviation of the binomial distribution is given by:
σ = sqrt(np(1-p))
Using these formulas, we can calculate the mean and standard deviation of the binomial distribution:
μ = 4000 x 0.002 = 8
σ = sqrt(4000 x 0.002 x 0.998) = 1.5811
The upper and lower control limits for the control chart can be calculated using the following formulas:
UCL = μ + 3σ
LCL = μ - 3σ
Substituting the values of μ and σ, we get:
UCL = 8 + 3 x 1.5811 = 12.7433
LCL = 8 - 3 x 1.5811 = 3.2567
Therefore, the upper control limit for the control chart is 12.7433 and the lower control limit is 3.2567. Any sample mean outside this range would be considered statistically significant and would require investigation to identify the cause of the deviation from the historical process average.

On a recent utility bill, the water/sewer/garbage portion of the bill was $94.41. This consisted of 72% of the total bill. To the nearest cent, what was the total amount of the utility bill?
Answer: We can start by using the information given to find the total bill amount.
If the water/sewer/garbage portion of the bill is 72% of the total bill, then the remaining 28% of the bill must be for other utilities. We can use a proportion to set up the equation:
72/100 = 94.41/x
where x is the total bill amount.
We can cross-multiply and solve for x:
72x = 100 * 94.41
x = (100 * 94.41) / 72
x = 123.84
To the nearest cent, the total amount of the utility bill was $123.84.
