Which statement is true regarding the graphed functions? ((help please :,)​

Therefore, the answer to the question is 0.7.

Explanation: In(2.1) is the natural logarithm of 2.1, which is approximately equal to 0.741. Rounding this number to the nearest tenth gives 0.7. When rounding decimals less than 1, it is important to include a leading 0 to avoid confusion.
To find In(2.1) rounded to the nearest tenth, we first need to know that In(2.1) is the natural logarithm of 2.1. This means that In(2.1) is the exponent to which the constant e (approximately 2.718) must be raised in order to get 2.1. Using a calculator, we can find that In(2.1) is approximately 0.741. Rounding this number to the nearest tenth gives us 0.7. It is important to include a leading 0 when rounding decimals less than 1 to avoid confusion.

Therefore, the answer to the question is 0.7 .

The mean of the sampling distribution of the difference in the sample proportions is an estimate of the difference in the population proportions, and the standard deviation of the sampling distribution measures the variability of this estimate.

The mean of the sampling distribution of the difference in the sample proportions (west minus east) of residents from the west and east who are in favor of building the bridge is 0.08. This means that on average, the sample from the west had a proportion that was 8% higher than the sample from the east in terms of favoring the new bridge.

The difference in sample proportions between the west and east can be interpreted as an estimate of the difference in the population proportions of residents who are in favor of building the bridge. Since the sample sizes are both 50 and greater than 30, we can use the central limit theorem to approximate the sampling distribution of the difference in sample proportions as a normal distribution.

The mean of this normal distribution is equal to the difference in population proportions, which is pW - pE = 0.30 - 0.20 = 0.10. The standard deviation of the sampling distribution can be estimated using the formula sqrt[(pW(1-pW))/nW + (pE(1-pE))/nE], where nW and nE are the sample sizes from the west and east, respectively.

Given the values provided, the estimated standard deviation is approximately 0.089.

Let's graph the equation

Notice that this equation corresponds to a line.

1. First, let's clear y, so we can get the equation of the line in the slope-intercept form:

This way, he equation of the line in the slope-intercept form is

2. Now, we have to expose two points contained in the line. To do so, we give x any value we want and we calculate the corresponding y value.

Let's do this with x = 0 and x = 1

3. Put those points in the cartesian plane:

4. Draw a straight line that passes through both points. This will be the graph of the line

The expression for the difference of two linear functions is (f - g)(x) = 4x - 6.

A linear function is a type of function in mathematics that has the form f(x) = mx + b, where x is the independent variable, f(x) is the dependent variable, m is the slope of the line, and b is the y-intercept.

To find the expression for the difference of two linear functions, f(x) and g(x), denoted by (f - g)(x).

The expression for (f - g)(x) can be found by subtracting g(x) from f(x):

(f - g)(x) = f(x) - g(x)

Substituting the given functions f(x) = x - 2 and g(x) = -3x + 4, we get:

(f - g)(x) = f(x) - g(x)

= (x - 2) - (-3x + 4) [Substitute the given values of f(x) and g(x)]

= x - 2 + 3x - 4 [Distribute the negative sign in front of (-3x + 4)]

= 4x - 6 [Combine like terms]

Therefore, (f - g)(x) = 4x - 6.

Option D (-3x² - 2x - 8) is incorrect as it involves squaring a linear expression, which would result in a quadratic expression. Option A (which has no operation between 3 and 22) is not a valid expression.

Where S is equal to 108, L is equal to 7 and W is equal to 3. We have:

The index number indicates that the value in period 7 has increased by about 119.83% compared to the value in period 1.

Based on the information provided, we will calculate the simple index number for period 7 (i7) using the given values for y1 and y7.

The simple index number formula is:

i7 = (y7 / y1) × 100

Where y1 represents the value in period 1 (116) and y7 represents the value in period 7 (255).

Plugging in these values, we get: i7 = (255 / 116) × 100 i7 ≈ 219.83

Thus, the simple index number for period 7 (i7) is approximately 219.83.

This index number is a measure that compares the value of y7 to the value of y1, with y1 being the base period.

= 784 feet

Height = 112 feet.

To find the height of the window, we can use the following kinematic equation for motion with constant acceleration:

y = yo + voyt + ½at²

Here, y is the final height of the ball above the ground, yo is the initial height of the ball (which is the height of the window in this case), voy is the initial velocity of the ball (which is 0 because the ball is dropped from rest), t is the time taken for the ball to hit the ground (which is 7 seconds), and a is the acceleration due to gravity (which is 32 ft/s²).

Substituting the values, we have:y = yo + 0 + ½(32)(7)

Simplifying the expression, we get:y = yo + 112

Thus, the height of the window (in feet) is given by:y = 112 feet

Hence, the probability that there will be no defective item during an 8-hour shift is e^(-8/ul) and the probability that you observe one defective item in less than 3 hours is 1 - e^(-3/ul).

a) Probability that there will be no defective item during an 8-hour shift can be calculated using the Poisson distribution formula, where the mean is given as λ:$$P(X=0) = \frac{\lambda^0 e^{-\lambda}}{0!}$$

Here, the mean is given as ul # which represents the number of defective items per unit of time.

Since the unit of time is not given, we can assume it as hours.

Therefore, the mean can be given as λ = 8/ul.

The formula can be substituted to find the probability:$$P(X=0) = \frac{\left(\frac{8}{ul}\right)^0 e^{-\frac{8}{ul}}}{0!}$$$$P(X=0) = e^{-\frac{8}{ul}}$$b) Probability that you observe one defective item in less than 3 hours can be calculated using the cumulative distribution function of exponential distribution, which is given as:$$F(x) = P(X \le x) = 1 - e^{-\frac{x}{\mu}}$$

Here, x is the time we need to find the probability for. Since the mean time between consecutive defective items is given as ul, the parameter μ of exponential distribution is also given as ul.

To find the probability that one defective item occurs in less than 3 hours, we need to find P(X < 3), which can be calculated as:$$P(X < 3) = F(3) = 1 - e^{-\frac{3}{ul}}$$

Answer:

Step-by-step explanation:

Given: Number of defective items in a production line per day follows a Poisson process, therefore the time between two consecutive defective items is exponentially distributed with a mean of ul.

a) The probability that there will be no defective item during the 8-hour shift is 0.3679.

b) The probability of observing one defective item in less than 3 hours is 0.021.

a) To find the probability that there will be no defective item during the 8-hour shift, we use the Poisson distribution with parameter λ = ul.

Hence, P(no defective item in 8 hours) = P(X=0),  where X ~ Poisson(λ).

P(X=0) = e^-λ λ^0 / 0!

= e^-λ

= e^-ul

= e^-(0.4*2.5)

= e^-1

= 0.3679

Therefore, the probability that there will be no defective item during the 8-hour shift is 0.3679.

b) The time between two consecutive defective items follows an exponential distribution with a mean of ul = 2.5.

Therefore, the parameter

λ = 1/ul

λ = 0.4.

The probability of observing one defective item in less than 3 hours is P(X=1), where X is the number of defective items in 3 hours.

Since the defective items follow a Poisson distribution, X ~ Poisson(λt), where λ = 0.4 and t = 3/8 (since 3 hours is 3/8 of the 8-hour shift).

P(X=1) = e^-λt (λt)^1 / 1!

= e^(-0.4*3/8) (0.4*3/8)^1 / 1!

= e^-0.15 * 0.15

= 0.021

Therefore, the probability of observing one defective item in less than 3 hours is 0.021.

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.
