Complete this sequence of numbers such that the difference between any two adjacent numbers is the same : 3/k, _, _, 9/2k.
The completed sequence is: 3/k, 3/k, 3/k, 9/2k.To complete the sequence of numbers with a constant difference between adjacent numbers, we can calculate the common difference by subtracting the first term from the second term.
Let's denote the missing terms as A and B.
The given sequence is: 3/k, A, B, 9/2k.
The common difference can be found by subtracting 3/k from A or B. Therefore:
A - 3/k = B - A = 9/2k - B.
To simplify, we can equate the two expressions for the common difference:
A - 3/k = 9/2k - B.
Next, we can solve for A and B using this equation.
Adding 3/k to both sides gives:
A = 3/k + 9/2k - B.
Now, we can substitute the value of A into the equation:
3/k + 9/2k - B - 3/k = 9/2k - B.
Simplifying further, we have:
9/2k - 3/k = 9/2k - B.
Cancelling out the common terms, we find:
-3/k = -B.
Multiplying both sides by -1, we get:
3/k = B.

The graph of y = 4 is blank line
Answer:
a horizontal
Step-by-step explanation:
The graph of y = 4 is a horizontal line. Horizontal lines have a slope of 0. In the y-intercept equation of y = mx + b, it then becomes y = b, making all horizontal equations in the form of y = b where b is the y-intercept.
Therefore, the answer is horizontal.

The function G(x) = sin(x) is the result of the application of transformations
on the original function F(x) = cos(x). Which of the following options
correctly describes the transformations applied to F(x)?
A. A phase shift of n radians
B. A vertical shift of -1 unit
T
C. A phase shift of radians
2
a
D. A vertical shift of 1 unit
Sell
Answer: shifted by π/2 radians
Step-by-step explanation:
The function sine of 'x' can be equated to the function cosine of 'x' by shifting cosine by 180 degrees. In math words:
\(sin(x)=cos(x-180)\)
The value 180 degrees in radians would be π/2. Therefore, in radians:
\(sin(x)=cos(x-\pi /2)\)
The 'x' inside of the functions is called the argument, and the value added or subtracted to the argument is the phase. The correct answer would be that sine is equal to cosine shifted by a phase of π/2 radians
In a recent year, 27.4% of all registered doctors were female. If there were 55,600 female registered doctors that year, what was the total number of registered doctors?
Answer:
The total number of registered doctors is 202,920 rounded.
Step-by-step explanation:
Solve for (x) in this equation: 27.4/100 = 55,600/(x)
You will get the following equation: (x)= (100*55,600) / (27.4) which equals 202,919.708 rounded to 202,920
To double check, you can see that 27.4% of the total given (202,920) equals the 55,600.

You mix 1/2 quart of blue paint for every 1/3 quart of red paint to make 5 quarts of purple paint.
Let 'x' be the amount of blue paint and 'y' be the amount of red paint. Then the equations are given as,
x / y = (1/2) / (1/3)
x / y = 3/2 ...1
x + y = 5 ...2
From equations 1 and 2, then we have
(3/2) y + y = 5
(5/2) y = 5
y = 2 quart
Then the value of 'x' is given as
x + 2 = 5
x = 3 quart
The amount of blue paint and red paint that you use will be 3 quarts and 2 quarts, respectively.

The mean and standard deviation (in ) of the sampling distribution of the difference in sample means \(\sigma_1\) - \(\sigma_2\) = (7)² ÷100+ 6² /150.
What is standard deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given:
Level A:
S.D. = 7
Level B: Mean = 20
S.D. = 6
So, \(\nu_1\) = 22
\(\nu_2\) = 20
Then, \(\nu_1\) - \(\nu_2\) = 22-20=2
and, \(\sigma_1\) - \(\sigma_2\)
= (7)² ÷100+ 6² /150

An item is regularly priced at $29. It is on sale for 80% off the regular price.
find the value of the ordinary annuity at the end of the indicated time period. the payment R, frequency of deposits m (which is the same as the frequency of compounding), annual interest rate r, and time period t are given. amount $600; quarterly; 7.6% six years. the value of the ordinary annuity is $_________ (round to the nearest cent as needed)
The formula of the value of the ordinary annuity is
\(A=R\cdot\frac{(1+\frac{r}{m})^n-1}{\frac{r}{m}}\)Where R represents the regular payments, m is the compounding periods, n is the number of regular payments, and A is the future amount. Let's use all the given values to find A. R = 600, r = 0.076 (7.6%), m = 4, and n = 24 (because we multiplied 6 years by 4).
\(\begin{gathered} A=600\cdot\frac{(1+\frac{0.076}{4})^{24}-1}{\frac{0.076}{4}} \\ A=600\cdot\frac{(1+0.019)^{24}-1}{0.019} \\ A\approx18,032.06 \end{gathered}\)Therefore, the value of the ordinary annuity is $18,032.06.Y=28x what is k constant of proportionality
The constant of proportionality is 28.
In the equation Y=28x, we can see that Y is directly proportional to x.
This means that as x increases or decreases, Y will increase or decrease in proportion.
The constant of proportionality, denoted by k, is the value that relates Y and x in the equation.
To find k, we can use the formula:
k = Y/x
So, in this case, k = 28.
This means that for every unit increase in x, Y will increase by 28 units.
Alternatively, for every unit decrease in x, Y will decrease by 28 units.
The constant of proportionality is an important concept in mathematics and science because it allows us to predict how changes in one variable will affect another variable.
By understanding the relationship between Y and x in this equation, we can use it to make predictions or solve problems in various fields, such as economics, physics, and engineering.
The equation y = 28x represents a proportional relationship between y and x, where y is 28 times as large as x.
The constant of proportionality (k) in this case is the factor that relates x to y.
Since y = 28x, we can see that k = 28.

what is the probability of rolling an odd number of dots with a fair, six-sided die numbered one through six? (enter your probability as a fraction.)
The probability of an odd number of dots by rolling with a fair, six-sided die numbered one through six is 1/2 or 50%.
There are three odd numbers (1, 3, and 5) on a six-sided die numbered from 1 to 6. Similarly, there are three even numbers (2, 4, and 6). Since the probability of rolling any one of the six numbers is the same, and half of them are odd and half are even, the probability of rolling an odd number is 3/6 or 1/2.
To determine the probability of rolling an odd number of dots, we need to consider the possible outcomes. We can roll an odd number of dots if we roll 1 or 3 or 5 dots on a single roll of the die. We can also roll an odd number of dots if we roll an even number of dots on two or more rolls.
Since these are mutually exclusive events, we can find the probability of rolling an odd number of dots by adding the probabilities of rolling 1, 3, or 5 dots to the probability of rolling an even number of dots twice, thrice, or more times.
The probability of rolling an even number of dots on any one roll is 1/2. So, the probability of rolling an even number of dots twice is (1/2) x (1/2) = 1/4, thrice is (1/2) x (1/2) x (1/2) = 1/8, and so on.
Therefore, the probability of rolling an odd number of dots is:
P(odd) = P(rolling 1) + P(rolling 3) + P(rolling 5) + P(even twice) + P(even thrice) + ...
P(odd) = 1/6 + 1/6 + 1/6 + 1/4 + 1/8 + ...
P(odd) = 1/2

In this case, the equation has a negative sign, which indicates that his function has a maximum point, which is the same point we are looking for in order to get the price widgets should be sold for, for the company to make the maximum profit. Now that we know that, let's go ahead and find the maximum value of the function. I'm gonna solve this on a digital board and attatch the images to this answer.

A study of black bears in the Adirondacks reveals that their population can be represented by the function P(t) = 3500(1.025)', where t is the number of years since the study began. Which function is correctly rewritten to reveal the monthly growth rate of the black bear population? Show work.
(1) P(t) = 3500(1.00206)¹²t
(2) P(t) = 3500(1.00206)¹/¹²
(3) P(t) = 3500(1.34489)¹²t
(4) P(t) = 3500(1.34489)¹/¹²
The function of the monthly growth rate is P(t) = 3500(1.34489)^t
How to determine the function of the monthly growth rateFrom the question, we have the following parameters that can be used in our computation:
P(t) = 3500(1.025)^t
This represents the annual growth function
Where t is the number of years
Convert time from years to months
So, we have
T = 12 * t
This means that we replace t with 12t in P(t) = 3500(1.025)^t
So, we have
P(t) = 3500(1.025)^(12t)
Evaluate the exponent
P(t) = 3500(1.34489)^t
Hence, the function is P(t) = 3500(1.34489)^t
