a) The sampling distribution of p can be approximated as a normal distribution with mean μp = .17 and standard deviation σp = .0203.

b) The probability that the sample proportion will be within ±.02 of the population proportion is 0.6778

In statistics, sampling distribution plays a crucial role in estimating the parameters of a population. The sampling distribution helps us to understand the probability distribution of sample statistics that we obtain by taking random samples from a population.

a) In this case, we are interested in the proportion of households that spend more than $100 per week on groceries, denoted by p. We know that the population proportion is p = .17, and a sample of 800 households will be selected from the population.

The central limit theorem states that if the sample size is large enough (in this case, n = 800), then the sampling distribution of p will be approximately normal with a mean of p and a standard deviation of:

σp = √(p(1-p)/n)

where p is the population proportion, and n is the sample size. Plugging in the values, we get:

σp = √(.17(1-.17)/800) = .0203

b) Now, we want to find the probability that the sample proportion will be within ±.02 of the population proportion. That is, we want to find P(.15 ≤ p ≤ .19).

To calculate this probability, we need to standardize the distribution using the z-score formula:

z = (p - μp) / σp

Plugging in the values, we get:

z = (.15 - .17) / .0203 = -0.9867

z = (.19 - .17) / .0203 = 0.9867

Using a standard normal distribution table or calculator, we can find the probabilities corresponding to these z-scores:

P(z ≤ -0.9867) = 0.1611

P(z ≤ 0.9867) = 0.8389

Therefore, the probability that the sample proportion will be within ±.02 of the population proportion is:

P(.15 ≤ p ≤ .19) = P(z ≤ 0.9867) - P(z ≤ -0.9867) = 0.8389 - 0.1611 = 0.6778

Step-by-step explanation:

Answer:

The slope of a function is the process of finding the rate of change of the value y (dependent variable) of the function changes with respect to that of the variable x (independent variable). The slope itself describes the direction and steepness of the line.

the slope (m) is (5 - -1) / 4 --3 = 6/7

Putting in the equation:

y - y1 = (6/7)(x - x1)

putting, y1= -1, x1= -3

y -  -1 = (6/7)( x - -3)

y + 1 = 6/7(x + 3)

If cosθ=-3/4 and tanθ is negative, then sinθ= √(7)/4.

Since cosθ = -3/4 and θ is an angle in the second quadrant where cosθ is negative, we know that sinθ must be positive.

The Pythagorean identity is a trigonometric identity that relates the three basic trigonometric functions: sine, cosine, and tangent

To find sinθ, we can use the Pythagorean identity

sin^2θ + cos^2θ = 1

Substituting the value of cosθ we get

sin^2θ + (-3/4)^2 = 1

Simplifying

sin^2θ + 9/16 = 1

sin^2θ = 7/16

Taking the square root of both sides, we get

sinθ = ±√(7)/4

Since we know that sinθ is positive in the second quadrant, we take the positive value

sinθ = √(7)/4

Step-by-step explanation:

You multiply 75% by every single number.

Multiply 675 by 40%.

The correct answer is (a) m < 0.Since line l contains points in quadrants I, II, and IV, but not in quadrant III, we can deduce the following.

Quadrant I: In this quadrant, both x and y coordinates are positive. For a line in quadrant I, the slope (m) must be positive. Quadrant II: In this quadrant, x coordinates are negative, and y coordinates are positive. For a line in quadrant II, the slope (m) must be positive. Quadrant IV: In this quadrant, x coordinates are positive, and y coordinates are negative. For a line in quadrant IV, the slope (m) must be negative.

Based on the observations in all the relevant quadrants, we can conclude that the slope (m) must be both positive and negative, indicating that it can take on both positive and negative values. Therefore, the correct answer is (a) m < 0.

A shear transformation in R2 is a linear transformation that displaces points in a shape. It is represented by a 2x2 matrix that captures the effects of the transformation. In the case of vertical shear, the matrix will have a non-zero entry in the (1,2) position, indicating the vertical displacement along the y-axis. For the given matrix | 1 k |, | 0 1 |, where k represents the shearing factor, the presence of a non-zero entry in the (1,2) position confirms a vertical shear. This means that the points in the shape will be shifted vertically while preserving their horizontal positions. In contrast, if the non-zero entry were in the (2,1) position, it would indicate a horizontal shear. Shear transformations are useful in various applications, such as computer graphics and image processing, to deform and distort shapes while maintaining their overall structure.

50 cars

Step-by-step explanation:

Let's define p as the number of people and c the number of cars.

We know that p / c = 3/5 or in other words, there are 5 cars every 3 people. If we have 30 people means that p = 30 which implies 30/c = 3/5 which implies c = 5/3 * 30 = 50.

Answer:

To find out how far a car will travel (in feet) before a driver reacts to an obstacle, given that the car is moving at 34 miles per hour in a residential neighborhood, we need to convert the speed of the car from miles per hour to feet per second. This can be done using the conversion factor that 1 mile per hour is equal to 1.46667 feet per second. Therefore, 34 miles per hour is equal to 34 x 1.46667 = 49.86678 feet per second.

We know that the average reaction time of the driver is 1.2 seconds, and we can use the following formula to calculate the distance traveled by the car before the driver reacts to the obstacle:

d = v x t

where d is the distance, v is the velocity, and t is the time taken. Using the formula above, we can calculate the distance traveled by the car before the driver reacts to the obstacle as:

d = 49.86678 x 1.2 = 59.84014 feet

Therefore, the car will travel 59.84014 feet before a driver reacts to an obstacle.

The NPV is positive, it is worth taking the Investment.

Net Present Value (NPV) is an assessment method that determines the attractiveness of an investment. It is a technique that determines whether an investment has a positive or negative present value.

This method involves determining the future cash inflows and outflows and adjusting them to their present value. This helps determine the profitability of the investment, taking into account the time value of money and inflation.The formula for calculating NPV is:

NPV = Σ [CFt / (1 + r)t] – CIWhere CFt = the expected cash flow in period t, r = the discount rate, and CI = the initial investment.

The given problem can be solved by using the following steps:

Calculate the present value (PV) of the expected cash inflows:

Year 1: $28,000 / (1 + 0.08)¹ = $25,925.93Year 2: $28,000 / (1 + 0.08)² = $24,009.11Year 3: $28,000 / (1 + 0.08)³ = $22,173.78Total PV = $72,108.82

Calculate the PV of the initial investment: CI = $7,000 / (1 + 0.08)¹ + $35,000 / (1 + 0.08)²CI = $37,287.43Calculate the NPV by subtracting the initial investment from the total PV: NPV = $72,108.82 – $37,287.43 = $34,821.39
