1 2 3 4 5 6 7 8 9 10 Susan plans to use 120 feet of fencing to enclose a rectangular area for a garden. Which equation best models the area, y, of the rectangular garden that she creates if one side is x feet long
Answer:
\(Area = 60x - x^2\)
Step-by-step explanation:
Given
\(Perimeter = 120\)
\(Side\ 1 = x\)
Required
The area of the garden
First, we calculate the length of the other side using:
\(Perimeter = 2 *(Side\ 1 + Side\ 2)\)
This gives:
\(120 = 2 *(x + Side\ 2)\)
Divide both sides by 2
\(60 = x + Side\ 2\)
Make Side 2 the subject
\(Side\ 2 = 60 - x\)
So, the area of the garden is:
\(Area = Side\ 1 * Side\ 2\)
\(Area = x * (60 - x)\)
Expand
\(Area = 60x - x^2\)
if x=2 and t=4 what is the value of 1/8 (x^3 - 4) (t^2 + 8)?
Answer:

Donna bought some bags at $10 each and sold them at $19 each. For customers who bought 2 bags, she gave them I bag free. If she earned $925 and gave away 11 free bags, how many customers bought only one bag?
Answer:
Donna earned a profit of $925, so she sold $925 / $9 profit per bag = 102.78 bags.
She gave away 11 free bags, so she actually sold 102.78 bags + 11 free bags = 113.78 bags.
113.78 bags / 3 bags per set = 37.92 sets of bags.
Therefore, 37.92 sets of bags * 2 bags per set = 75.84 bags were sold in sets of 2.
Therefore, 113.78 bags - 75.84 bags = 37.94 bags were sold individually.
Therefore, 37.94 bags were bought by customers who bought only one bag.

In what percentage of such groups (of 400) would 150 or fewer improve? round your answer to one decimal place
The percentage of such groups (of 400) would 150 or fewer improve is 16.60.
The percentage is a relative value indicating the hundredth component of any quantity. One percent (symbolized 1%) is the 100th element; as a result, 100 percent represents the entirety and 2 hundred percent specifies twice the given amount. percentage.
As finding 10% of a variety of means to divide through 10, it is not unusual to assume that to locate 20% of a variety you must divide through 20 and so on. Take into account, to discover 10% of the number of manner dividing through 10 because 10 is going into one hundred ten times. consequently, to discover 20% of various, divide via five due to the fact 20 is going into 100 five times.
In arithmetic, a percentage is a number or ratio expressed as a fraction of one hundred. it's far frequently denoted by the usage of the percentage signal, "%", although the abbreviations "pct.", "pct" and on occasion "computer" also are used.

As the semester goes on, the number of days until final exams decreases.As a person's peanut butter consumption increases, her miles traveled to work doesn't change (no direct relationship can be inferred). As the speed of a car increases, the stopping distance of the car increases.As the number of calculations increases, the probability of making an error can't say anything (the relationship between the two factors is not specified).As the demand for housing increases, the price of housing increases.
(a) As the semester goes on, the number of days until final exams decreases. This is because the number of days until final exams is a countdown towards a fixed event. As each day passes, the remaining number of days decreases until reaching zero on the day of the final exams.
(b) As a person's peanut butter consumption increases, her miles traveled to work doesn't change. There is no direct relationship between peanut butter consumption and miles traveled to work. These two variables are unrelated and one cannot infer any correlation or causation between them.
(c) As the speed of a car increases, the stopping distance of the car increases. This is due to the physics of motion. When a car is traveling at higher speeds, it covers more distance during the reaction time of the driver, and it requires a longer distance to come to a complete stop due to the increased kinetic energy. Therefore, as the speed increases, the stopping distance also increases.
(d) As the number of calculations increases, the probability of making an error can't be said with certainty. The probability of making an error depends on various factors, such as the complexity of the calculations, the proficiency of the person performing the calculations, and the presence of any systematic errors. While it is generally true that more calculations may increase the chances of making errors, it is not a definitive rule and can vary based on individual circumstances.
(e) As the demand for housing increases, the price of housing increases. This is due to the basic principle of supply and demand. When there is high demand for housing and limited supply, sellers can charge higher prices. The increased competition among buyers drives the prices up. Conversely, if the demand for housing decreases, sellers may have to lower their prices to attract buyers.

A univerity tate that mean ECLSE core of their graduate i 1200. You do a tudy for your univerity and take a random ample of 100 tudent elected and if the ample mean i 1180. Aume that the ample tandard deviation i 100 and are approximately normally ditributed. Tet the theory that the mean ECLSE tet core i equal to 1200 at 95% ignificance level
The null hypothesis for this test is that the mean ECLSE test score for the university is equal to 1200. The alternative hypothesis is that the mean is not equal to 1200.
To perform the test, you will need to calculate the t-statistic and the p-value. The t-statistic is calculated by:
t = (sample mean - hypothesized mean) / (sample standard deviation/sqrt (sample size))
In this case, the sample mean is 1180, the hypothesized mean is 1200, the sample standard deviation is 100, and the sample size is 100. Plugging these values into the equation gives:
t = (1180 - 1200) / (100 / sqrt(100)) = -20 / 10 = -2
Next, you will need to calculate the p-value. The p-value is the probability of observing a t-statistic as extreme as the one calculated, given that the null hypothesis is true.
To calculate the p-value, you will need to use a t-distribution table or a software package to find the t-critical value for a one-tailed test with 99 degrees of freedom (since you have a sample size of 100) and a significance level of 0.05. The t-critical value is the value that defines the rejection region for the test. If the t-statistic falls in the rejection region, you can reject the null hypothesis.
If the p-value is less than the significance level of 0.05, you can reject the null hypothesis and conclude that the mean ECLSE test score for the university is not equal to 1200 at the 95% significance level. If the p-value is greater than or equal to 0.05, you cannot reject the null hypothesis and cannot conclude that the mean is different from 1200.

Work Shown:
Let's make each of those unlabeled angles be angle y.
We have two copies of y, since the arcs are the same (meaning they are congruent angles) and 44 as well.
The three interior angles of any triangle add to 180
44+y+y = 180
2y+44 = 180
2y = 180-44 ... subtracting 44 from both sides
2y = 136
y = 136/2 ... divide both sides by 2
y = 68
Once we know y, we can find x
x+y = 180 ... since the adjacent angles form a straight line
x+68 = 180
x = 180-68 ... subtract 68 from both sides
x = 112

Find the derivative of the function at P in the direction of A f(x,y,z):xy + yz + zx, (1,-1,-2), A = 3i + 2j - 6k (DAf) | 1(1,-1,-2) =
Therefore, the directional derivative of f at P=(1,-1,-2) in the direction of A=3i+2j-6k is -2.
To find the directional derivative of f(x,y,z) at P=(1,-1,-2) in the direction of A=3i+2j-6k, we first need to find the gradient of f at P, which is given by:
grad(f) = ∇f = (∂f/∂x)i + (∂f/∂y)j + (∂f/∂z)k
Here, f(x,y,z) = xy + yz + zx, so we have:
∂f/∂x = y + z
∂f/∂y = x + z
∂f/∂z = x + y
Thus, at P=(1,-1,-2), we have:
∇f(P) = (∂f/∂x)i + (∂f/∂y)j + (∂f/∂z)k
= (y+z)i + (x+z)j + (x+y)k
= (0+(-2))i + (1+(-2))j + (1+0)k
= -2i - 1j + 1k
Next, we need to find the unit vector in the direction of A:
|A| = sqrt(3^2 + 2^2 + (-6)^2) = 7
u = A/|A| = (3/7)i + (2/7)j - (6/7)k
Finally, we can compute the directional derivative of f at P in the direction of A as:
(DAf) | 1(1,-1,-2) = ∇f(P) · u
= (-2i - 1j + 1k) · (3/7)i + (2/7)j - (6/7)k
= -6/7 - 2/7 - 6/7
