What is the area of this trapezoid?
The first four laguerre polynomials are 1, 1 - t, 2 - 4t t2, and 6 - l 8t 9t2 - t 3 . show that these polynomials form a basis of lp'3?
The polynomials 1, 1-t, \(2-4t+t^2\) and \(6-18t+9t^2-t^3\) are linear independent and span \(P_3\). So the first four Laguerre polynomials forms a basis of \(P_3\).
We have the first four Laguerre polynomials. Here \(P_3\) is the space of all polynomials of degree at most 3.
i.e., \(P_3= \{ a+bx+cx^2+dx^3| a,b,c,d \in R\}\)
So the dimension of \(P_3\) is 4. Also there are 4 Laguerre polynomials.
Now to show that the first four Laguerre polynomials forms a basis, it remains to show that they are linear independent.
Consider the polynomials 1, 1-t, \(2-4t+t^2\) and \(6-18t+9t^2-t^3\). Write them into a matrix with the co-efficient of 1, t, \(t^2\) and \(t^3\) in each row.
\(\left[\begin{array}{cccc}1&1&2&6\\0&-1&-4&-18\\0&0&1&9\\0&0&0&-1\end{array}\right]\)
This matrix is already in its echelon form with all its pivots occupied. The pivot of first row is 1. The pivot of 2nd row is -1. The pivot of 3rd row is 1 and the pivot of 4th row is -1.
Hence the polynomials are linearly independent since the columns of the above matrix are linearly independent.
In conclusion, the first four Laguerre polynomials 1, 1-t, \(2-4t+t^2\) and \(6-18t+9t^2-t^3\) forms a basis for \(P_3\).

Independent random samples arise when ...
a. one random sample is split into groups differing by an observed feature
b. the individuals in a sample are randomly assigned to experimental groups
c. data is recorded repeatedly on a random sample of individuals
d. random samples are selected separately
2. The margin of error of a confidence interval about the difference between the means of two populations is equal to
a. half the width of the confidence interval
b. twice the width of the confidence interval
c. the width of the confidence interval
d. 1.5 times the width of the confidence interval
1. Independent random samples arise when one random sample is split into groups differing by an observed feature is incorrect.
2. The margin of error of a confidence interval about the difference between the means of two populations is equal to half the width of the confidence interval.
1. Independent random samples arise when individuals in a sample are randomly assigned to experimental groups, data is recorded repeatedly on a random sample of individuals, or random samples are selected separately. The statement that one random sample is split into groups differing by an observed feature does not accurately describe independent random samples.
2. The margin of error in a confidence interval represents the range of values within which the true population parameter is likely to fall. It is calculated by taking half of the width of the confidence interval. Therefore, the correct answer is that the margin of error is equal to half the width of the confidence interval.
In summary, the incorrect statement is that independent random samples arise when one random sample is split into groups differing by an observed feature. The margin of error of a confidence interval about the difference between the means of two populations is equal to half the width of the confidence interval.

Any disease of the adrenal gland 64. Pertaining to the body 65. Any disease of the thyroid gland 66. Tumor of the pancreatic islets 67. Activated by epinephrine 68. Pertaining to the pancreatic islets 69. Enlargement of the thyroid 70. Acting on the thyroid 71. Acting on the body 72. Acting on reproductive organs
63. "Adrenopathy" is the correct term for any disease of the adrenal gland.
64. Corporeal. 65. Thyropathy 66. Isletoma 67. Adrenergic 68. Islet-related 69. Goiter 70. Thyrotropic 71. Somatic 72. Gonadotropic
63. Adrenopathy: The correct word parts to form the term that describes any disease of the adrenal gland are "adreno-" and "-pathy." The prefix "adreno-" refers to the adrenal gland, and the suffix "-pathy" indicates a disease or disorder.
64. Corporeal: To describe something pertaining to the body, the correct word part is "corpor-" which means body. By adding the suffix "-eal" meaning pertaining to, we form the term "corporeal" which means relating to the body.
65. Thyropathy: When combining the word parts for a disease of the thyroid gland, we use "thyro-" to refer to the thyroid gland and "-pathy" to indicate a disease or disorder. Thus, "thyropathy" is the term that describes any disease of the thyroid gland.
66. Isletoma: A tumor of the pancreatic islets can be described using the word parts "islet-" referring to the pancreatic islets and "-oma" which signifies a tumor. Therefore, "isletoma" is the appropriate term for a tumor of the pancreatic islets.
67. Adrenergic: To indicate something that is activated by epinephrine, the correct word part is "adreno-" referring to the adrenal gland, and the suffix "-ergic" indicating activation or stimulation by a substance. Thus, "adrenergic" describes something that is activated by epinephrine.
68. Islet-related: The word part "islet-" refers to the pancreatic islets. To describe something pertaining to the pancreatic islets, we can use the suffix "-related." Therefore, "islet-related" is the correct term for something pertaining to the pancreatic islets.
69. Goiter: Enlargement of the thyroid is commonly referred to as a "goiter." In this case, the specific word parts from the bank are not used to form the term.
70. Thyrotropic: When we want to describe something that acts on the thyroid, the appropriate word parts are "thyro-" for the thyroid gland and the suffix "-tropic" indicating an agent that acts upon or influences something. Thus, "thyrotropic" is the correct term for something acting on the thyroid.
71. Somatic: To describe something that acts on the body, the word part "somato-" is used, which refers to the body. Therefore, "somatic" is the term that describes something acting on the body.
72. Gonadotropic: The word part "gonado-" is used to refer to the reproductive organs. When we want to describe something that acts on the reproductive organs, the suffix "-tropic" is used, indicating an agent that acts upon or influences something. Therefore, "gonadotropic" is the correct term for something acting on the reproductive organs.

Solve this equation: 2(m+10) = 4(m-15)
Answer:
The value of m is 40
Step-by-step explanation:
2(m + 10) = 4(m - 15)
2m + 20 = 4m - 60
20 + 60 = 4m - 2m
80 = 2m
2m = 80
m = 80 ÷ 2
m = 40
Thus, The value of m is 40
-TheUnknownScientist
Answer:
40
Step-by-step explanation:
2 ( m + 10 ) = 4 ( m - 15 )
Divide 2 on both sides,
m + 10 = 2 ( m - 15 )
m + 10 = 2m - 30
10 + 30 = 2m - m
40 = 1m
m = 40 / 1
m = 40
suppose the 99% confidence interval for the mean sat scores of applicants at a business college is given by [1,692, 1,842]. this confidence interval uses the sample mean and the sample standard deviation based on 25 observations. what are the sample mean and the sample standard deviation used when computing the interval?
The upper bound is 1842 and lower bound is 1692. By using these boundaries and t-table, the sample mean is 1767 and sample standard deviation = 133.98.
Here, the two boundaries are 1692 and 1842.
Mean = (1692+1842) /2 = 1767
Here the degree of freedom, df = (n-1) = 25-1 =24
Margin of error = (1842-1692)/2 = 75
Confidence level = 99%
From the t table, value of T with confidence level 99% and df= 24 is 2.80
The equation for margin of error is M = Ts/√n
M= 75 , T= 2.80, n =25
75 = (2.80 × s) / √25
75 = 2.80s/ 5
s = (75×5)/2.80 = 133.928 = 133.93
So the sample mean is 1767 and the standard deviation is 133.93.
