Let log_b 4= G and log_b9= S. Write the expression in terms of G and S
S-G is the expression in terms of G and S
What is the expression in terms of G and S?Given: log_b 4 = G, log_b9 = S and log_b 9/4
To write log_b 9/4 in terms of G and S, we need to understand logarithm division rule, which states that:
When you divide two values with the same base is to subtract the exponents. Simply, the rule for division is to subtract the logarithms i.e.
logₓ (a/c) = logₓa - logₓc
Thus, log_b (9/4) = log_b 9 - log_b 4 = S - G
(Note: log_b 4 = G and log_b9= S)
Therefore, the expression log_b (9/4) in terms of G and S is S-G

If the nth partial sum of a series n = 1 as it approaches infinity an is sn = 6 - n5^-n, find an and n = 1 as it approaches infinity an.
By using the partial sum of series is
\(a_{n} = 5^{(-n-1) } - (n+1)5^{(-(n+1))}\)
and summation n=1 to infinity of \(a_{n}\) is =6 .
How to find the nth term?To obtain the formula for the nth term of the series and its total, we must first discover the formula for the series' general term.
The formula for the series' nth partial sum is as follows:
\(sn = 6 - n*5^{-n}\)
The nth term of the series can be obtained by subtracting the (n+1)th and nth partial sums, i.e.,
a = sn+1 - sn
When we substitute the formula for sn, we get:
\(a_{n} = [6 - (n+1)5^{(-(n+1))} ] - [6 - n5^{(-n)} ]\\a_{n} = 5^{(-n-1) } - (n+1)5^{(-(n+1))}\)
As a result, the formula for the series' nth term is:
\(a_{n} = 5^{(-n-1) } - (n+1)5^{(-(n+1))}\)
To calculate the series total, take the limit of the nth partial sum as n approaches infinity:
lim(n->inf) lim(n->inf) sn [6 - n*5^(-n)]
lim(n->inf) [n*5(-n)] = 6
= 6 - 0
= 6
As a result, the series' sum is 6.
As a result, the formula for the nth term in the series is:
\(a_{n} = 5^{(-n-1) } - (n+1)5^{(-(n+1))}\)
And the series' total is:
a = sum(n=1 to inf) = 6

What is the range of the absolute value function below?
The range of the absolute value function y = |x| is all non-negative numbers, which can be expressed as [0, ∞).
The absolute value function is a type of mathematical function that measures the distance between a given number and zero. It is denoted by two vertical bars surrounding the number or expression.
The range of the absolute value function is the set of all non-negative numbers. This is because the absolute value of any number is always a positive number or zero.
For example, the absolute value of 3 is 3, and the absolute value of -3 is also 3.This means that the output of the function can never be negative and can range from zero to infinity.

Use the following table to find the probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing. Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Students on the Student Government Board
On-Campus Housing Off-Campus Housing
Freshman 2 2
Sophomore 2 4
Junior 0 3
Senior 4 2
Graduate Student 2 0
The probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing is 8/25 or 0.32 (rounded to the nearest millionth).
1. Calculate the total number of students on the Student Government Board by summing up the numbers in the table:
Total Students = 2 + 2 + 2 + 4 + 0 + 3 + 4 + 2 = 19
2. Calculate the total number of graduate students on the Student Government Board:
Total Graduate Students = 2 + 0 = 2
3. Calculate the total number of students living in on-campus housing:
Total On-Campus Housing = 2 + 2 + 0 + 4 + 2 = 10
4. Calculate the probability of selecting a graduate student from the Student Government Board by dividing the total number of graduate students by the total number of students:
Probability of Graduate Student = Total Graduate Students / Total Students = 2 / 19
5. Calculate the probability of selecting a student living in on-campus housing by dividing the total number of students in on-campus housing by the total number of students:
Probability of On-Campus Housing = Total On-Campus Housing / Total Students = 10 / 19
6. Calculate the probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing by summing up the probabilities from steps 4 and 5:
Probability = Probability of Graduate Student + Probability of On-Campus Housing = 2 / 19 + 10 / 19
7. Simplify the fraction if necessary. In this case, the fraction cannot be simplified further, so the final probability is 2 / 19 + 10 / 19 = 12 / 19.
8. Convert the fraction to a decimal by dividing the numerator by the denominator: 12 / 19 ≈ 0.631578947, which rounds to 0.632 (rounded to the nearest thousandth).
9. Finally, express the probability as a fraction in lowest terms: 12 / 19 is already in lowest terms.
Therefore, the probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing is 12/19 or approximately 0.632 (rounded to the nearest thousandth).

Answer:
hello your question is incomplete below is the complete question
A company's human resources department was interested in the average number of years that a person works before retiring. The sample of size 11 follows: 12 16 18 19,21 21, 21,22 24 24 26What is the arithmetic mean, median and mode? what is the most likely shape of the distribution
answer :
i) mean = 20.36
ii) median = 21
iii) mode = 21
iv) The most likely shape is a Bell - shaped curve
Step-by-step explanation:
sample size = 11
values ( observations ) = 12, 16, 18, 19,21,21,21,22,24,24,26
i) mean
= ∑ values / sample size = 224 / 11 = 20.36
ii) median
median is the value of the data located at the center of the string of data
to determine the middle position = ( n+1 / 2 )
where n = sample size
hence position of median value = 11 + 1 / 2 = 12 / 2 = 6
the value at the 6th position = 21 ( median )
iii) mode
mode = most repeated value in the series of data
hence mode value = 21
Evaluate the double integral. 4y2 dA, D is the triangular region with vertices (0, 1), (1, 2), (4, 1)
Answer:
44/3
Step-by-step explanation:
Let A be the line joining the vertices (0, 1) and (1,2) while B be the equation of the line joining (1, 2) and (4, 1).
The equation of a line joining points \((x_1,y_1) \ and\ (x_2,y_2)\ is:\\\\\)
\(y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\)
The equation of line A joining (0, 1) and (1,2) is:
\(y-1=\frac{2-1}{1-0} (x-0)\\\\y-1=x\\\\x=y-1\)
The equation of line D joining (1, 2) and (4,1) is:
\(y-2=\frac{1-2}{4-1} (x-1)\\\\y-2=-\frac{1}{3} (x-1)\\\\3y-6=-x+1\\\\x=-3y+7\)
Therefore the change in y is: 1 ≤ y ≤ 2, while change in x is: y-1 ≤ x ≤ -3y + 7. Hence the double integral is:
\(\int\limits^2_1\int\limits^{-3y+7}_{y-1} {4y^2} \, dx dy\\\\=4\int\limits^2_1\int\limits^{-3y+7}_{y-1} {y^2} \, dx dy\\\\=4\int\limits^2_1y^2dy[x]^{-3y+7}_{y-1} \\\\=4\int\limits^2_1y^2dy(-3y+7-(y-1))\\\\=4\int\limits^2_1y^2dy(-4y+8)\\\\=4\int\limits^2_1(-4y^3+8y^2)dy\\\\=4[-y^4+\frac{8}{3}y^3 ]^2_1\\\\=4(\frac{11}{3} )\\\\=\frac{44}{3 }\)
To answer this question, we need, first get the equations for the lines that enclosed the surface, and integrate according to the limits obtained from these equations give.
The solution is:
A = 44/3 square units
Let´s call points:
P ( 0 , 1 ) Q ( 1 , 2 ) and R ( 4 , 1 )
The equation for the line between, P and R is:
y = 1
The equation for the line between, P and Q is:
Slope-intercept equation is y = m×x + b
The slope m₁ = ( 2 - 1 ) / ( 1 - 0 ) m₁ = 1
and the line passes over the point x = 0 y = 1 ; then
1 = 0 +b b = 1
y = x + 1 ⇒ x = y - 1
The equation for the line between Q and R is:
m₂ = ( 1 - 2 ) / ( 4 - 1) m₂ = - 1/3
y = ( -1/3)× x + b
when x = 1 y = 2
2 = ( - 1/3)×(1) + b
2 + 1/3 = b
b = 7/3
y = - (x/3) + 7/3 ⇒ x = 7 - 3×y
The double integral becomes:
A = 4×∫∫ y² dx dy ⇒ A = 4 ×∫₁² y²dy ∫dx | (y - 1 ) y ( 7 - 3y)
A = 4×∫₁² y²dy × x | ( y - 1 ) y ( 7 - 3y)
A = 4 ×∫₁² y²dy × [ 7 - 3×y - ( y - 1 )]
A = 4 ×∫₁² y²dy × (8 - 4×y ) ⇒ A = 4 ×∫₁² (8×y² - 4×y³ ) dy
A = 4 × [ (8/3)×y³ - y⁴ | ₁²
A = 4 × [ 64/3 - 16 - (8/3) + 1 ]
A = 4 × ( 56/3 - 15 )
A = 4 × ( 56 - 45 /3)
A = 4 × 11/3

In a right-angled triangle, a ² + b ² = c ².
angles in a triangle add up to 180°.
Sine rule: a/SIN A = b/SIN B = c/SIN C
angle C = 90° (little square means 90).
if angle A is 30, then angle B must be 180 - 90 - 30 = 60°.
using the Sine rule:
a/Sin A = c/Sin C
multiply both sides by Sin A:
a = (c Sin A) / Sin C
= (12 Sin 30) / Sin 90
= 6.
so a = 6.
Using Pythagoras (In a right-angled triangle, a ² + b ² = c ²),
c² = a² + b²
b² = c² - a²
= 12² - 6²
= 144 - 36
= 108
so b² = 108
b = √108
angle B is correct

What is P(not divisor of 6)?
Write your answer as a fraction or whole number.
1/3
Step-by-step explanation:The notation P(x) is used to describe the probability of event x occurring.
Divisors
Before we can do the probability question, we need to find the divisors of 6. Divisors are numbers that can evenly divide another number. The factors and divisors of a number are the same. So, 6 has 4 divisors:
1, 2, 3, and 6All of these values are on a 6-sided dice. So, in this probability question, there are 4 unsuccessful outcomes.
Probability
The probability of a simple event is the number of successful outcomes divided by the number of possible outcomes. In this situation, there are 6 possible outcomes, each side of the dice. Four of these outcomes do not satisfy the given condition (not a divisor of 6). Thus, there are 2 successful outcomes.
\(\frac{2}{6} =\frac{1}{3}\)The probability of rolling a number that is not a divisor of 6 is 1/3.
