The formulas for calculating changes in the money supply are as follows. Firstly, Money Multiplier = 1 / Reserve Ratio. Finally, to calculate the maximum change in the money supply, use the formula Change in Money Supply = Change in Reserves * Money Multiplier.
The women’s heptathlon in the Olympics consists of seven track and field events: the 200-m and 800-m runs, 100-m high hurdles, shot put, javelin, high jump, and long jump. In the 2000 Olympics, the best 800-m time, run by Gertrud Bacher of Italy, was 8 seconds faster than the mean. The winning long jump by the Russian Yelena Prokhorova was 60 centimeters longer than the mean. Bacher’s winning 800-m time of 129 seconds was 8 seconds faster than the mean qualifying time of 137 seconds (the standard deviation of the qualifying times was 5 seconds). Prokhorova’s winning long jump was 60cm longer than the average 6-m jump (Note: the standard deviation of the long jumps was 30 cm). Which performance is more outstanding (and hence deserves more points when computing their overall score)? Explain.
Answer: Prokhorova is more outstanding.
Step-by-step explanation: To compare scores from different distributions, first standardize it:
z-score = [tex]\frac{x-\mu}{\sigma}[/tex]
where
x is the individual mean you want to compare
μ is the mean of the population
σ is standard deviation
For Gertrud Bacher:
z-score = [tex]\frac{129-137}{5}[/tex]
z-score = [tex]-1.6[/tex] (s)
The negative sign indicates Bacher's mean is less than the mean
For Yelena Prokhorova:
z-score = [tex]\frac{660-600}{30}[/tex]
z-score = 2 (cm)
The positive sign indicates Prokhorova's mean is more than the mean.
Using z-score table, you determine the percentiles are:
For Bacher: Percentile = 5.5%
For Prokhorova: Percentile = 97.7%
Bacher's percentile means she is above 5.5% of the participants, while Prokhorova is 97.7% above the other competitors, which means Prokhorova have a better performance and deserves more points.

express as a single logarithm 3 loga (2x+1) - 2 loga (2x-1) +2
Answer:
Step-by-step explanation:
[tex]3 \log_{a} (2x+1)=\log_{a}(2x+1)^{3}[/tex]
[tex]2 \log_{a}(2x-1)=\log_{a}(2x-1)^{2}[/tex]
[tex]2=\log_{a}(a^{2})[/tex]
So the expression can be expressed as a single logarithm as follows:
[tex]3\log_{a}(2x+1)-2\log_{a}(2x-1)+2=\log_{a}(2x+1)^{3}-\log_{a}(2x-1)^{2}+\log_{a}a^{2}[/tex]
[tex]3\log_{a}(2x+1)-2\log_{a}(2x-1)+2=\log_{a}\left(\frac{(2x+1)^{3}a^{2}}{(2x-1)^{2}}\right)[/tex]

Write an equation for a polynomial with all the following features:
a. The degree is 5.
b. The polynomial has 4 terms.
c. The graph of the polynomial crosses the vertical axis at Y = 12 .
Identify the approximate input values of any relative maximums and minimums of this 5th degree polynomial.
Answer:
Step-by-step explanation:
(x-1)^5 = x^5 - 5x^4 + 15x^3 - 15x^2 + 5x - 1
That has 6 terms, so let's get rid of the two middle ones.
f(x) = (x-1)^5 - 15x^2(x-1)
Now, f(0) = 1, but we want f(0) = 12
So, let
f(x) = 12((x-1)^5 - 15x^2(x-1)) = 12x^5 - 60x^4 + 60x - 12
As for the graph, it looks like
y = (x+4)(x+2)(x-1)^2(x-6)
The extrema appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)
The relative maximums and minimums of this 5th-degree polynomial appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)
What is a polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
The degree of the polynomial is 5.
The polynomial has 4 terms
So (x-1)⁵ = x⁵ - 5x⁴ + 15x³ - 15x² + 5x - 1
Let's eliminate the two middle terms from it, which has six.
f(x) = (x-1)⁵ - 15x²(x-1)
Given that the graph of the polynomial crosses the vertical axis at Y = 12
So, substitute f(0) = 1, but we determine f(0) = 12
So, let f(x) = 12((x-1)⁵ - 15x²(x-1)) = 12x⁵ - 60x⁴ + 60x - 12
As for the graph, it looks like
So the approximate input values of relative maximums and minimums of this 5th-degree polynomial :
y = (x+4)(x+2)(x-1)²(x-6)
The relative maximums and minimums of this 5th-degree polynomial appear to be at about (-3,1), (-1,-1), (1,0), (4,-9)

In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.From this, we have that the slope represents a rate of change, hence, option B is correct.

how do you write this in slope intercept form i don’t know
Answer: y = [tex]-\frac{2}{1.5}[/tex]x + 15
Step-by-step explanation:
Slope intercept form is written as y = mx + b, where m is the slope and b is the y- intercept.
2.00x + 1.50y = 15
1.50y = -2.00x + 15
y = [tex]\frac{-2}{1.5}[/tex]x + 15
determine the y- intercept of 3x+2y=9
Answer:
The y intercept is (0,4.5)
Step-by-step explanation:
Because the y-intercept occurs at x = 0, we can substitute this into our equation and solve for y.
3(0) +2y = 9
2y = 9
y=4.5
Answer:
[tex]\boxed{(0 , 4.5)}[/tex]
Step-by-step explanation:
→ Rearrange into y = mx + c format
2y = - 3x + 9
→ Divide everything by 2
y = -1.5x + 4.5
→ Substitute x = 0
y = 0 + 4.5 ⇒ 4.5

Answer:
A: 13 1/3 daysB: 40 daysStep-by-step explanation:
If person A can paint the house in 'a' days, then person B takes 3a days. Each day, the total amount of house painted when they work together is ...
1/a + 1/(3a) = 1/10
4/(3a) = 1/10 . . . combine terms
40 = 3a . . . . . . . cross multiply
a = 40/3 = 13 1/3 . . . . . divide by 3
A can paint the house in 13 1/3 days.

here is a list 31 29 33 37 43 38 33 40 find the mode in number of list and work out on mean
Answer: Mode = 33, Mean = 35.5
Step-by-step explanation: The mode is whatever number appears the most.
To find the mode, first put the numbers in order from least to greatest.
29, 31, 33, 33, 37, 38, 40, 43
In this case, 33 appears the most, so the mode is 33.
The mean is the average of all of the numbers.
Firstly, add up all of the numbers:
29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284
Now that you have all of them added up, divide the final sum by the number of numbers you have in the list. In this case, you have 8 numbers.
284/8 = 35.5
Your mean is 35.5
Answer:
Mode = 33
Mean = 35.5
The mode is whatever number appears the most.
to find the mean:
add all the numbers:
29 + 31 + 33 + 33 + 37 + 38 + 40 + 43 = 284
divide that by the number of numbers you have in the list.
284/8 = 35.5
mean = 35.5
