It is 1/2 mile from the students home to a store and back. In a week, she walked to the store and back home 1 time. In the same week, she rode her bike to the store and back 3 times. How many miles did she walk and ride to the store and back in that week?

Answer: h = 6

explanation:

first u get h by itself

4h + 6 = 30

subtract 6 from both sides

4h = 24

divide by 4 on both sides

h = 6

Answer:h=3/13

Step-by-step explanation: Subtract 6  from both sides of the equation 4h+6-6=30h-6 you simplify 4h=30h-6. Subtract 30h  from both sides of the equation then you get -26h=-6 then you divide both sides of the equation by the same term -26h/-26=-6/-26 and your answer is 3/13.

The P94 value is the 35th value in the sorted data set, which is 8600.

To obtain the 94th percentile (P94) from the given data, you need to identify the value that separates the top 94% of the data from the remaining 6%.

First, arrange the data in ascending order:

1000 1100 1800 1900 2100 2400 2600 2700 2800 2900 3100 3200 3300 3500 3700 3800 3900 4000 4300 4400 4700 5100 5200 5300 5800 6100 6400 7100 7200 7400 7700 7900 8200 8300 8400 8600 8700 8800 8900

Since there are 36 data points, the 94th percentile corresponds to the 94th percentile rank, which can be calculated as (94/100) * (36 + 1) = 34.56. Since this is not a whole number, we need to round up to the next whole number, which is 35.

The effective rate of interest for 1 year is 22.14%.

The formula to calculate the effective rate of interest (APY) is:

APY = (1 + r/n)^n - 1

Where:r = annual interest rate as a decimal, n = number of compounding periods per year.

We know that the principal amount is 18,000, the interest rate is 20%, and the interest is compounded quarterly. Therefore, the number of compounding periods per year is:

n = 4

Using the above formula and substituting the given values in it, we get:

APY = (1 + r/n)^n - 1

APY = (1 + 0.2/4)^4 - 1

APY = 1.2214 - 1

APY = 0.2214 or 22.14% (rounded to the nearest hundredth)

Therefore, the effective rate (APY) of interest for 1 year at a 20% interest rate compounded quarterly is 22.14%.

The probabilistic approach characterized by PERT does not use the median activity times.

The probabilistic approach characterized by PERT stands for Program Evaluation and Review Technique. It is a statistical tool used to evaluate and estimate the time required to complete a project. The PERT method is based on a three-point estimation technique, which takes into account the best case, worst case, and most likely case scenarios for each activity involved in the project management process.

The PERT formula is used to calculate the expected time required to complete a project. The formula is based on the three-point estimation technique used by the PERT method. The formula for calculating the expected time for an activity is as follows:

Expected time = (optimistic time + (4 x most likely time) + pessimistic time) / 6Where,Optimistic time is the shortest possible time required to complete an activityMost likely time is the most probable time required to complete an activityPessimistic time is the longest possible time required to complete an activity

The PERT method is a valuable tool for project managers as it provides a statistical estimation of the time required to complete a project. By using the three-point estimation technique, project managers can evaluate the best case, worst case, and most likely case scenarios for each activity involved in the project management process.

Answer:

y = -0.25x + 40 ; $26,000

Step-by-step explanation:

From the graph attached ;

The regression equation, y could be obtained :

y = mx + c

m = slope = Rise / Run = (y2 - y1) / (x2 - x1)

Slope = (15 - 40) / (100 - 0)

Slope = - 25 / 100

Slope = - 0.25

c = intercept, where the regression line crosses the y-axis, from. The graph, c = 40

The regression equation goes thus :

y = -0.25x + 40 ; y = price of car ; x = number of miles driven

Price of car that has been driven for 56000 miles

y = - 0.25(56) + 40

y = - 14 + 40

y = 26

Hence, price of car is $26,000

The following statements about the correlation coefficient (rho) between two variables x and y are correct: The value of rho ranges between -1 and 1. If rho = 1, it indicates a perfect positive linear relationship between x and y. If rho = -1, it indicates a perfect negative linear relationship between x and y. If rho = 0, it indicates no linear relationship between x and y.

The correlation coefficient (rho) measures the strength and direction of the linear relationship between two variables x and y. It ranges between -1 and 1. Here's an explanation of each statement:

1. The value of rho ranges between -1 and 1: The correlation coefficient is a standardized measure, and it takes values between -1 and 1, inclusive. A value of -1 indicates a perfect negative linear relationship, 0 indicates no linear relationship, and 1 indicates a perfect positive linear relationship.

2. If rho = 1, it indicates a perfect positive linear relationship between x and y: When rho equals 1, it means that the variables x and y have a perfect positive linear relationship. This means that as x increases, y also increases in a consistent manner.

3. If rho = -1, it indicates a perfect negative linear relationship between x and y: When rho equals -1, it means that the variables x and y have a perfect negative linear relationship. This means that as x increases, y decreases in a consistent manner.

4. If rho = 0, it indicates no linear relationship between x and y: When rho equals 0, it means that there is no linear relationship between the variables x and y. In other words, the variables are not linearly associated with each other.

These statements summarize the key properties of the correlation coefficient and its interpretation in terms of the relationship between two variables.

The standard deviation of the distribution of sample means is approximately 2.331.

The mean of the distribution of sample means, also known as the sampling distribution mean, is equal to the population mean. In this case, the population mean (μ) is given as 31.3. Therefore, the mean of the distribution of sample means is also 31.3.

The standard deviation of the distribution of sample means, also known as the standard error, can be calculated using the formula:

Standard Error = Population Standard Deviation / √(Sample Size)

In this case, the population standard deviation (σ) is given as 18.4, and the sample size (n) is 62. Plugging these values into the formula, we get:

Standard Error = 18.4 / √(62)

Standard Error ≈ 2.331

Using the law of sines, the value of q is: D. 72.7.

The law of sines is given as: sin A/a = sin B/b = sin C/c.

Thus, given △PQS, where:

m∠Q = 22°

m∠S = 65°

s = 176

Applying the law of sines, we have:

sin Q/q = sin S/s

Substitute

sin 22/q = sin 65/176

q = (sin 22 × 176)/sin 65

q = 72.7

An urn contains 4 green balls and 8 red balls. (a) The probability of getting a red ball is 2/3. (b) If you select two balls, the probability that one (but not both) is red is 16/33. (c) The probability that the second ball is red is 14/33.

(a) The probability of getting a red ball = Number of red balls / Total number of balls= 8 / (4 + 8) = 8/12= 2/3

(b) The probability of selecting one red ball out of 2 balls = (Number of ways to select one red ball from 8) × (Number of ways to select one green ball from 4) = (8/12) × (4/11) = 8/33

The probability of selecting one green ball out of 2 balls = (Number of ways to select one green ball from 4) × (Number of ways to select one red ball from 8) = (4/12) × (8/11) = 8/33

Therefore, the probability that one (but not both) is red = 8/33 + 8/33= 16/33

(c) After the first ball is selected, there will be 11 balls left in the urn, including 7 red and 4 green. The probability of selecting a red ball = Number of red balls left / Total number of balls left= 7 / 11

Therefore, the probability that the second ball is red = 8/12 × 7/11= 14/33.

Using the Mean Value Theorem, sin xsin y ≤ x − y| for all real numbers x and y, sinx is uniformly continuous on R.

The Mean Value Theorem states that if a function is continuous on a closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one point c in (a, b) where the derivative of the function is equal to the average rate of change of the function over [a, b].

Applying this theorem to the function f(x) = sin x on the interval [x, y], we can find a point c between x and y where the derivative of f(x) is equal to the average rate of change of f(x) over [x, y].

Since the derivative of sin x is cos x, we have cos c = (sin y - sin x) / (y - x). Rearranging the inequality, we get sin y - sin x ≤ cos c (y - x). Now, using the fact that |cos c| ≤ 1, we can rewrite the inequality as sin y - sin x ≤ |y - x|. Thus, sin xsin y ≤ x - y| for all real numbers x and y.
