The odds against Jenny winning a headset are 88.89% or 8 out of 9, and the odds in favor of Jenny winning a headset are 11.11% or 1 out of 9.
Since Jenny won a charity raffle, and her prize will be randomly selected from the 9 prizes shown below, and the prizes include 7 rings, 1 camera, and 1 headset, to find the odds against Jenny winning a headset, and find the odds in favor of Jenny winning a headset, the following calculations must be performed:
· 1 headset out of 9 total prizes

Using the concept of perimeter of polygon, the perimeter of figure C is 27cm shorter than total perimeter of A and B
How much shorter is the perimeter of C than the total perimeter of A and B?To solve this problem, we have to know the perimeter of the polygon C.
The perimeter of a polygon is the sum of all the lengths of the outer edges of the figure, that is, we must find the length of all the edges of the polygon, and then add these lengths to obtain the perimeter.
The perimeter of the figures are;
Using the concept of perimeter of a rectangle;
a. figure A = 2(4 + 11) = 30cm

Answer:
Hello again! Fellow Connexus user? Because I just had this on my Honors Algebra 1 test today. Anyways the answer is: A. x + y = 126 and 2.25x + 1.50y = 225.75; 49 Hot Dogs and 77 Sodas.
Step By Step Explanation:
To verify just use the substitution method to solve the equations x+y=126 and 2.25x + 1.50y = 225.75 then you'll get your x (Number of Hotdogs) and y (Number of Sodas)
Hope this helps!
The required equations are use to solve this problem;
\(x + y =126\)
\(2.25x + 1.50y = 223.75\)
There are x = 49 hot dogs, and y = 77 sodas were sold.
Given that,
Each hot dog costs $2.25 and each soda costs $1.50.
At the end of the night, you made a total of $225.75.
You sold a total of 126 hot dogs and sodas combined.
We have to determine,
What equations did you use to solve this.
And How many hot dogs were sold and how many sodas were sold.
According to the question,
Let, The x represent the number of hot dogs,
And y represent the number of sodas.
Then,
You sold a total of 126 hot dogs and sodas combined.
Number of sell hot dogs + number of sell sodas = Total of hot dogs and sodas combined.
\(x + y =126\)
And Each hot dog costs $2.25 and each soda costs $1.50.
At the end of the night, you made a total of $225.75.
Then,
Cost of each hot dogs + cost of each soda = total earning end of the night
\(2.25x + 1.50y = 223.75\)
On solving both the equation,
\(x + y = 126\\\\x = 126-y\)
Substitute the value of x in the equation 2,
\(=2.25(126-y) + 1.50y = 225.75\\\\= 283.5 -2.25y + 1.50y = 225.75\\\\= - 0.75 y = 225.75 - 283.5\\\\= - 0.75y = -57.75\\\\= y = \dfrac{-57.75}{-0.75}\\\\= y = 77\)
Then,
Substitute the value of y in the equation 1,
\(x + y = 126\\\\x + 77 = 126\\\\x = 126-77\\\\x = 49\)
Hence, There are x = 49 hot dogs, and y = 77 sodas were sold.

Answers
The correct option, C. The function is positive when x > 0, for the graph of cube root parent function.
Define the term cube root parent function?The opposite of such cubic function is the cube root function.
We are aware that its parent cubic function is ascending, one-one, and onto, and that its form is f(x) = x³. It results in a bijection as a result. As a result, its cube root inverse function, of the type f(x) = ∛x, also forms a bijection.The definition of the cube root for all numbers may be found in the introduction, as we have already seen (positive, real, and 0). As a result, there is no x for which any cube root function, f(x), is not defined. Therefore, the set among all real numbers is its domain (R).Similar to the square root function, the range of a cube root function is the set among all real numbers because it produces all values (positive, real, and 0). Consequently, a cube root function is f(x): R → R.Thus, using the domain and range we can see from the graph that, for the positive values of the function, the graph is increasing for positive values.
Therefore, The function is positive when x > 0.

Convert the equation f(t) = 227e b= -0.09€ to the form f(t) = ab* Give answers accurate to three decimal places
Answers
= 173.903t
Step-by-step Explanation:
The given equation is: f(t) = 227e^(b*t)
To convert it to the form f(t) = ab, we need to write it in the form of f(t) = a * e^(k*t), where a and k are constants.
Let's start by taking the natural logarithm (ln) of both sides:
ln(f(t)) = ln(227e^(b*t))
Using the properties of logarithms, we can simplify this to:
ln(f(t)) = ln(227) + ln(e^(b*t))
ln(f(t)) = ln(227) + b*t
Now, let's define a new constant, k = b, and rewrite the equation in terms of a and k:
ln(f(t)) = ln(a) + k*t
where a = 227 and k = -0.09
Taking the exponential of both sides, we get:
f(t) = e^(ln(a) + k*t)
f(t) = e^(ln(a)) * e^(k*t)
f(t) = a * e^(k*t)
Substituting the values of a and k, we get:
f(t) = 227 * e^(-0.09*t)
Therefore, the equation f(t) = ab is:
f(t) = 227e^(-0.09t) ≈ 173.903t (rounded to three decimal places)

The following currents are present in the circuit: I₁ = 0.492 A, I₂ = -0.428 A, I₃ = 0.920 A. They are found by Kirchoffs law and solving simultaneously.
Inequalities: what are they?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
Kirchoff's law and Junction Law will be applied given the various resistances and the circuit.
Apply Kirchoff's law to the left side loop as a starting point.
E₁ + E₂ = (r₁ + R₁ + R₄) I₁ + ( R₂ + r₂ ) I₃
18 + 3 = ( 0.5 + 8 + 15 ) I₁ + ( 10 + 0.25 ) I₃

Apply Kirchoff's law to the right side loop as the next step.
