Step-by-step explanation:
The ratio of blue paint to yellow paint that makes the green paint is 5:9. This means that for every 5 gallons of blue paint, 9 gallons of yellow paint are used. To determine which of the given ratios will make the same shade of green paint, we can simplify them to see if they are equivalent to the ratio 5:9.
10:18 simplifies to 5:9 (dividing both sides by 2), so this ratio will make the same shade of green paint.
6:10 simplifies to 3:5 (dividing both sides by 2), so this ratio will not make the same shade of green paint.
30:54 simplifies to 5:9 (dividing both sides by 6), so this ratio will make the same shade of green paint.
27:15 simplifies to 9:5 (dividing both sides by 3), so this ratio will not make the same shade of green paint.
So, the ratios that will make the same shade of green paint are 10:18 and 30:54.

p(x)=5x^4+7x^3-2x^2-3x+c divided by (x+1)
Answers
The remainder is 5 + c, which means that the expression P(x) = \(5x^4 + 7x^3 - 2x^2 - 3x + c\) divided by (x + 1) results in a quotient of\(5x^3 + 2x^2 - 4x + 4\) and a remainder of 5 + c.
To divide the polynomial P(x) = \(5x^4 + 7x^3 - 2x^2 - 3x + c\) by the binomial (x + 1), we can use polynomial long division.
Let's set up the long division:
\(5x^3 + 2x^2 - 4x + 4\)
_______________________
x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)
We start by dividing the highest degree term of the dividend (5x^4) by the divisor (x + 1), which gives us 5x^3. We then multiply this quotient by the divisor (x + 1) and subtract it from the dividend:
\(5x^3(x + 1)\)
_______________________
x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)
- (\(5x^3 + 5x^2)\)
This leaves us with a new polynomial:\(2x^3 - 7x^2 - 3x + c\). We repeat the process by dividing the highest degree term of this polynomial (2x^3) by the divisor (x + 1), resulting in 2x^2. We then multiply this quotient by the divisor and subtract it from the polynomial:
\(5x^3(x + 1) + 2x^2(x + 1)\)
_______________________
x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)
-\((5x^3 + 5x^2)\)
_______________________
\(2x^2 - 3x + c\)
We continue this process until we reach the constant term, resulting in the remainder of the division.
At this point, we have:
\(5x^3(x + 1) + 2x^2(x + 1)\)
_______________________
x + 1 | \(5x^4 + 7x^3 - 2x^2 - 3x + c\)

Note that given that the temperature is modeled as a sinusoidal function, the temperature, to the nearest degree, at 9 AM is 51 degrees Fahrenheit.
What is the rationale for the above response?To model the outside temperature over a day as a sinusoidal function, we need to determine the amplitude, period, phase shift, and vertical shift.
A sinusoidal function is a mathematical function that describes a wave-like pattern that repeats itself over a period of time or distance and can be modeled using sine or cosine functions.
Given that the high temperature of 68 degrees occurs at 6 PM, we can assume that this is the maximum temperature for the day, which corresponds to the amplitude of the sinusoidal function. Thus, the amplitude is 6 degrees.
Since the average temperature for the day is 55 degrees, this corresponds to the vertical shift of the sinusoidal function. Therefore, the equation for the temperature function is:
T(t) = 6sin(ωt + φ) + 55
where ω is the angular frequency, and φ is the phase shift.
The period of the sinusoidal function is 24 hours, since the temperature pattern repeats itself every 24 hours. Therefore, the angular frequency is:
ω = 2π/period = 2π/24 = π/12
To find the phase shift, we need to determine how much the function is shifted to the right or left. Since the high temperature of 68 degrees occurs at 6 PM, which is 12 hours after midnight, the phase shift is:
φ = -ωt = -(π/12)(12) = -π
Therefore, the equation for the temperature function is:
T(t) = 6sin(π/12 * t - π) + 55
To find the temperature at 9 AM, we use the equation for the temperature function:
T(t) = 6sin(π/12 * t - π) + 55
Substituting t = 9 into the equation, we get:
T(9) = 6sin(π/12 * 9 - π) + 55
Simplifying the argument of the sine function:
π/12 * 9 - π = π/4
Substituting into the equation:
T(9) = 6sin(π/4) + 55
Using the value of sin(π/4) from the unit circle:
sin(π/4) = √2/2
Substituting into the equation:
T(9) = 6(√2/2) + 55
Simplifying:
T(9) = 3√2 + 55
Approximating to the nearest degree:
T(9) ≈ 51 degrees
Therefore, the temperature at 9 AM is approximately 51 degrees Fahrenheit.

B) Repeat part (a) using a sample size of n = 500.
C) If we took many samples of size 50 from the population of all inductees and recorded the proportion who were performers for each sample, what shape do we expect the distribution of sample proportions to have where do we expect it to be centered?
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
center is 0.275
\(SE = 0.063\)
b
center is 0.275
\(SE = 0.020\)
Step-by-step explanation:
considering question a
From the question we are told that
The sample size is n = 50
The proportion of US adults are college graduates is p = 0.275
Generally the center is equivalent to the proportion so the center is 0.275
Generally the standard error is
\(SE = \sqrt{\frac{p * (1- p)}{ n} }\)
=> \(SE = \sqrt{\frac{0.275 * (1- 0.275)}{ 50} }\)
=> \(SE = 0.063\)
considering question b
The sample size is n = 500
The proportion of US adults are college graduates is p = 0.275
Generally the center is equivalent to the proportion so the center is 0.275
Generally the standard error is
\(SE = \sqrt{\frac{p * (1- p)}{ n} }\)
=> \(SE = \sqrt{\frac{0.275 * (1- 0.275)}{ 500} }\)
=> \(SE = 0.020\)
In the sampling distribution, the center of the sampling distribution is 0.275 and the standard error is 0.063.
What is sampling distribution?A sampling distribution simply means the probability distribution that is gotten from a larger number of samples that are drawn from a population.
In this case, the center of the sampling distribution is 0.275 and the standard error is 0.063. The standard error will be:
= [p × (1 - p)]/n
= [0.275 × (1 - 0.275)]/50
= 0.0039875
= ✓0.0039875
= 0.063
Also, when the sample is 500, the center of the sampling distribution is 0.275 and the standard error is 0.020.

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answers
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

Given that P(x)=x^5-8x^3-x^2+2, what is the remainder when it is divided by x-5?
Answers
Answer:
2102
Step-by-step explanation:
The polynomial function P(x)=x^5-8x^3-x^2+2, if it is divided by x-5, first we need to get x from the divisor as shown
since d(x) = x-5
x-5 = 0
x = 5
Substitute x = 5 into the expression to get the remainder
P(x)=x^5-8x^3-x^2+2
P(5)=(5)^5-8(5)^3-(5)^2+2
P(5) = 3125-1000-25+2
p(5) = 2100+2
P(5) = 2102
Hence the remainder is 2102

x is the divisor
Dividend = 19, 432
