Answer:

6.0

Explaination: this is because you round down if your number is smaller than 5. in this case it is.

The solutions to the equation are x= -9 and x = 6

From the information given, we have that;

|x2 + 9x| = 6x + 54

To solve the quadratic equation, collect the like terms, we have;

x² + 9x - 6x = 54

subtract the terms

x² + 3x = 54

Put in standard form

x² + 3x - 54 = 0

Find the pair factors of -54 that add up to give 3 and substitute the values

x² + 9x - 6x - 54 = 0

group in pairs

(x² + 9x) - (6x - 54) = 0

factorize the expressions

x(x + 9) - 6(x + 9) = 0

Then, we have;

x- 6 = 0

x = 6

x + 9 = 0

x = -9

Answer:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Step-by-step explanation:

The compound inequality for the given situation is $2.75x + $4.25y ≥ $65 and $2.75x + $4.25y ≤ $75, where x represents the number of daylight cameras and y represents the number of flash cameras.

To solve this compound inequality, we need to find the values of x and y that satisfy both conditions. The inequality $2.75x + $4.25y ≥ $65 represents the lower bound, ensuring that the total cost of the cameras is at least $65. The inequality $2.75x + $4.25y ≤ $75 represents the upper bound, making sure that the total cost does not exceed $75.

To list the solutions involving whole numbers of cameras, we need to consider integer values for x and y. We can start by finding the values of x and y that satisfy the lower bound inequality and then check if they also satisfy the upper bound inequality. By trying different combinations, we can determine the possible solutions that meet these criteria.

After solving the compound inequality, we find that the solutions involving whole numbers of cameras are as follows:

(x, y) = (10, 10), (11, 8), (12, 6), (13, 4), (14, 2), (15, 0), (16, 0), (17, 0), (18, 0), (19, 0), (20, 0).

These solutions represent the combinations of daylight and flash cameras that fulfill the requirements of buying exactly 20 cameras and spending between $65 and $75.

In sharecropping contracts, the landlord receives a fixed share of the output, while in fixed rent contracts, the landlord receives a fixed amount. On the other hand, in sharecropping contracts, the tenant receives a fixed share of the output, whereas in fixed rent contracts, the tenant receives a fixed amount.

Sharecropping and fixed rent contracts are two different arrangements between landlords and tenants in agricultural settings. In a sharecropping contract, the landlord's compensation depends on the output of the land. Specifically, the landlord receives a fixed share or proportion of the output produced by the tenant. This means that if the tenant's effort leads to a high output, the landlord's share will be larger, and if the output is low or zero, the landlord's share will be correspondingly smaller. The tenant, in turn, receives a fixed share of the output as their compensation.

On the other hand, in a fixed rent contract, the landlord's compensation is predetermined and does not depend on the output. The landlord receives a fixed amount of rent regardless of the output produced by the tenant. This fixed amount ensures that the landlord's income remains stable and is not influenced by the variability of agricultural output. In this case, the tenant also receives a fixed amount as their compensation, which is unaffected by the output.

50 apartments were randomly chosen by our pupils. We found 26 residences with owners. We could use this to determine our sample proportion, by the way. It will come out to 26 out of 50 and.52. We're going to conduct an experiment to test the hypothesis that your neighborhood's owner-occupied home percentage differs from the national average.

The null hypothesis will be the outcome of the test. The null hypothesis states that 69 is the actual proportion. The alternative is an alternate theory. We are endeavoring to determine whether the community is different from the country, per the inquiry. I'll concede that the actual ratio is not 0.69. It is necessary to find the test statistic. We are permitted to utilize the calculator function in the tests because this is an example Z test. Yes, a window. We could locate the single proportion Z if we went to the tests and clicked the stat. It's basically a test. The Christmas component cost 69 dollars. Out of 50 samples, 26 have resulted in success.

In our alternative, the true percentage is different from.69, therefore proportion does not equal zero proportion. A negative Z score of 2.599 will be the outcome in the end. The window gives us a p value of 9. We'll choose a resolution. We will compare the p value to our significance level. It doesn't specify the degree of relevance for this problem. We'll only use 5%. So, if our p value is less than the significance level, we would reject the null hypothesis, right? The sample proportion must be obtained. If the null hypothesis is true, it would be extremely rare, since our community has more owner-occupied homes than the national average, according to the data.

Step-by-step explanation:

We simply add the respective horizontal and vertical components:

\(c+d=\langle 6,2 \rangle+\langle-9,7\rangle=\langle6+(-9),2+7\rangle=\langle6-9,9\rangle=\langle-3,9\rangle\)

On squaring both sides of the equation, we will not get answer from the options. Rather, the resultant equation will be 6x² + 84 - 60x - 8✓3x = 0.

Let us square both the sides to find the desired equation.

(✓3x + 4)² = (1 + 3x - 11)²

Solving the Right Hand Side of the equation

(✓3x + 4)² = (3x - 10)²

So, on we have (a+b)² on Left Hand Side of the equation and (a-b)² on Right Hand Side of the equation. We know the expanded form to be used here is -

Left Hand Side = a² + b² + 2ab

Right Hand Side = a² + b² - 2ab

So, finding the square now -

(✓3x)² + 4² + 2×4×✓3x = 3x² + 10² - 2×3x×10

Solving both sides of the equation

3x² + 16 + 8✓3x = 9x² + 100 - 60x

Rewriting the equation

9x² - 3x² + 100 - 16 - 60x - 8✓3x = 0

Step-by-step explanation:

The probability of having a positive profit after 6 months is approximately 0.64 (0.32 + 0.32).

To calculate the probability of having a positive profit after 6 months, we need to determine the range of stock prices that will result in a profit.

Since the straddle pays the absolute difference between the stock price after 6 months and 42, we can express the profit as follows:

Profit = | Stock price - 42 |

A positive profit will occur if the stock price is either higher than 42 or lower than -42.

To calculate the probability of either of these scenarios occurring, we need to know the probability distribution of the stock price after 6 months.

Assuming the stock price follows a normal distribution, we can use the standard deviation of the stock price to calculate the probability of a positive profit.

Let's say the standard deviation of the stock price after 6 months is σ.

The probability of the stock price being higher than 42 is equal to the probability of the stock price being more than σ away from the mean (since the mean is 42).

Using a standard normal distribution table, we can find that the probability of a normal random variable being more than 1 standard deviation away from the mean is approximately 0.32.

Therefore, the probability of the stock price being higher than 42 is approximately 0.32.

Similarly, the probability of the stock price being lower than -42 is also approximately 0.32.

Answer:

y = - 3x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y = 3 ( subtract 3x from both sides )

y = - 3x + 3 ← in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + c ← is the partial equation

To find c substitute (- 1, 2) into the partial equation

2 = 3 + c ⇒ c = 2 - 3 = - 1

y = - 3x - 1 ← equation of parallel line

The required equation of line which passes through points (-1, 2) and parallel to line 3x + y = 3 is 3x + y = -1

Slope is a notation that shows that a surface of which one end or side is at a higher level than another surface.

y - y₁ = m(x - x₁)

The given equation of line,

3x + y = 3,        

The slope of the given line is -3,

The equation of the line that passes through points (-1, 2) and which is parallel to line 3x + y = 3

The slope of the required line will be same as slope of line 3x + y = 3.

The equation of line,

y - 2 = -3 (x - (-1))

y - 2 = -3 (x + 1)

y - 2 = -3x - 3
