The statement, " If set {v₁..... Vₙ} spans finite-dimensional vector-space V and if T is a set of more than n vectors in V, then T is linearly-dependent." is True because the set-T is linearly-dependent.
If T is a set of more than p vectors in V, where p is the dimension of V, then T is necessarily linearly dependent because if T contains more vectors than the dimension of the vector-space, there must exist a linear dependence among the vectors in T.
In other words, it is not possible for T to be linearly-independent since the dimension of V is n, and T contains more than "n" vectors.
Therefore, the statement is True.

calculate the effective rate (APY) of interest for 1
year. (round your final answer to the neareast hundreth
percent)
principal = 18,000
interest rate : 20%
compound quarterly
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%.

h =___?
Im in 7th grade and I really need help
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.

A population of values has a normal distribution with 4 = 31.3 and o random sample of size n = 62. 18.4. You intend to draw a What is the mean of the distribution of sample means? What is the standard deviation of the distribution of sample means?
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
Therefore, the standard deviation of the distribution of sample means is approximately 2.331.

if rho is the correlation coefficient between two variables x and y, then which of the following statements are correct?
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.

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 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.

Trucking is considering whether to expand its service. The expansion requires the expenditure of $10,500,000 on new service equipment and would generate annual net cash inflows from reduced costs of operations equal to $3,500,000 per year for each of the next 9 years. In year 9 the firm will also get back a cash flow equal to the salvage value of the equipment, which is valued at $0.9 million. Thus, in year 9 the investment cash inflow totals $4,400,000. Calculate the project's NPV using a discount rate of 7 percent.

Show, using the Mean Value Theorem, that sin xsin y ≤ x − y| for all real numbers x and y. b) Prove, using a), that sinx is uniformly continuous on R.
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.

An urn contains 4 green balls and 8 red balls. (a) If you select one ball, what is the probability it is red? (b) If you select two balls, what is the probability that one (but not both) is red? (c) If you select one ball without replacement, and then select another one, what is the probability that the second ball is red?
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.
