If a person is randomly selected, the probability provided the condition is P(Female | Suwanee) is 1/3.
What is the probability?Probability is used to determine the odds in favor or against a random event happening. The odds in favor or against an event happening has a probability value that lies between 0 and 1.
The higher the odds of an event happening, the closer the probability value would be to 1. If it is equally likely that the event might happen or not happen, the probability value will be 0.5.
P (Female | Suwanee) is the probability that a person is female given that the person is from Suwanee.
P (Female | Suwanee) = total number of females from Suwanee / total number of people from Suwanee

What is the end behavior of the polynomial function?
Drag the choices in to the boxes to correctly describe the end behavior of the function.
Answers
The end behaviours of the functions are
f(x) = 6x⁹ - 6x⁴ - 6: As x ⇒ +∝, f(x) ⇒ +∝ and as x ⇒ -∝, f(x) ⇒ -∝f(x) = -3x⁴ - 6x + 4x - 5: As x ⇒ +∝, f(x) ⇒ -∝ and as x ⇒ -∝, f(x) ⇒ -∝How to determine the end behaviours of the functions?Function 1
The equation of the function is given as
f(x) = 6x⁹ - 6x⁴ - 6
Calculate f(∝) and f(-∝)
So, we have
f(∝) = 6(∝)⁹ - 6(∝)⁴ - 6
Evaluate
f(∝) = ∝ - ∝ - 6
So, we have
f(∝) = ∝
Also, we have
f(-∝) = 6(-∝)⁹ - 6(-∝)⁴ - 6
Evaluate
f(-∝) = -∝ - ∝ - 6
So, we have
f(∝) = -∝
This means that
As x ⇒ +∝, f(x) ⇒ +∝ and as x ⇒ -∝, f(x) ⇒ -∝
Function 2
The equation of the function is given as
f(x) = -3x⁴ - 6x + 4x - 5
Evaluate the like terms
f(x) = -3x⁴ - 2x - 5
Calculate f(∝) and f(-∝)
So, we have
f(∝) = -3(∝)⁴ - 2(∝) - 5
Evaluate
f(∝) = -∝ - ∝ - 5
So, we have
f(∝) = -∝
Also, we have
f(-∝) = -3(-∝)⁴ - 2(-∝) - 5
Evaluate
f(∝) = -∝ + ∝ - 5
So, we have
f(∝) = -∝
This means that
As x ⇒ +∝, f(x) ⇒ -∝ and as x ⇒ -∝, f(x) ⇒ -∝

Find odds in favor of winning ring and find against winning the ring
Answers
We have a randomly selected prize out of 9 objects (4 rings, 4 headsets and 1 camera).
a) We have to calculate the odds in favor of Mary winning a ring.
The odds can be expressed as the proportion (or quotient) between the probabilities of winning a ring and the probabilities of not winning a ring.
This will also be equal to the number of outcomes that will be a ring (4 elements are rings) divided by the number of outcomes that are not a ring (5 elements are not a ring):
[tex]o_{wr}=\frac{4\/9}{5\/9}=4:5[/tex]b) Now, we have to calculate the odds against Mary winning a ring.
This will be the inverse of the previous result, as we have to divide the probability of not winning a ring by the probability of winning.

continued - calculating gross payRemember, this is money round to the nearest Penny/hundredths place.
Answers
ANSWER:
Regular pay is $383.2
Overtime rate is $14.37
Overtime pay is $114.96
Gross pay is $498.16
STEP-BY-STEP EXPLANATION:
Assuming the overtime multiplier is 1.5 and the standard work week is 40 hours. Therefore, we calculate the regular payment like this:
[tex]RP=40\cdot9.58=383.2[/tex]The overtime rate would be the value of the normal payment times the overtime multiplier, like this
[tex]OTR=9.58\cdot1.5=14.37[/tex]Then we multiply the number of additional hours to the 40 hours allowed, that is, 8 (48 - 40), for which one gives overtime pay
[tex]OTP=8\cdot114.96=114.96[/tex]Now the gross pay would be the sum of the regular payment with the overtime payment:

She invested some of it in an account that paid 5% simple interest per year, and she invested the rest in an account that paid 9% simple interest per year. After one year, she received a total of $2580 in interest. How much did she invest in each account?First account:Second account:
Answers
Answer:
She invested an amount of $3,000 in the first accont and $27,000 in the second account
Explanation:
Here, we want to get the amount invested in each of the accounts
To get this,let us write the simple interest formula
Mathematically, we have this as:
[tex]I\text{ = }\frac{PRT}{100}[/tex]Let the amount invested in the first account be $x, while that of the second account be $y
P represent the amounts invested
R is the rate of investment
T is the time (1 year)
The sum of these two is the $30000 she has to invest
Mathematically, we have this as:
[tex]x\text{ + y = 30000}[/tex]Let us get the interests on each of the accounts
For the first account, we have the interest as:
[tex]I_1\text{ = }\frac{x\times5\times1}{100}\text{ = }\frac{5x}{100}[/tex]For the second account, we have the interest as:
[tex]I_2\text{ = }\frac{y\times9\times1}{100}\text{ =}\frac{9y}{100}[/tex]The sum of these two is the interest value, which is as follows:
[tex]\begin{gathered} I_1+I_2\text{ = }\frac{5x}{100}+\frac{9y}{100}\text{ = 2580} \\ \\ 5x\text{ + 9y = 258000} \end{gathered}[/tex]So, we have two equations to solve simultaneously
The two equations are:
[tex]\begin{gathered} x\text{ + y = 30000} \\ 5x\text{ + 9y = 258000} \end{gathered}[/tex]We can solve this by substitution
Let us substitute for y
[tex]y\text{ = 30000-x}[/tex]Insert this into the second equation, we have this as:
[tex]\begin{gathered} 5x\text{ + 9(30000-x) = 258000} \\ 5x\text{ + 270000-9x = 258000} \\ 9x-5x\text{ = 270000-258000} \\ 4x\text{ = 12000} \\ x\text{ = }\frac{12000}{4} \\ x\text{ = 3,000} \end{gathered}[/tex]Recall:
[tex]y\text{ = 30000-x = 30000-3000 = 27000}[/tex]What this mean is that:

The measure of an angle and it’s complement differ by 22 degrees. Find the larger angle.
Answers
The measure of an angle and its complement differ by 22 degrees and the larger is 56°
What are Complementary Angles?The total of the two angles' measurements determines their complement and supplement. The pair of angles is said to be complimentary if the product of the two angles equals the measurement of a right angle.
1. If the total of two angles equals 90°, the angles are considered to be complements of one another.
2. Let x° and y° be the two angles. Since they complement one another, the two angles' sum will be 90 degrees.
= x + y = 90°. (Assume equation 1 is used.)
3. The two angles differ by 22 degrees, hence the equation will be,
= x - y = 22°. (Put equation 2 in.
4. To determine the values of x and y, solve equations 1 and 2.
Add equations 1 and 2 together.
= x + y + x - y = 90 + 22,
= 2x = 112°,
= x = 56°.
5. In equation 1, change the value of x.
= 56° + y = 90°,
= y = 90 -56,
= y = 34°.
So, the measure of the two angles is 56°, and 34°.
And the larger angle is 56°

Given:
m∠A = (4x - 2) degrees
m∠B = (11x + 17) degrees
Let's find the value of x if the angles A and B are complementary angles.
Complementary angles are angles that sum up to 90 degrees.
Hence, we have:
m∠A + m∠B = 90
(4x - 2) + (11x + 17) = 90
Let's solve for x.
• Remove the parentheses:
4x - 2 + 11x + 17 = 90
• Combine like terms:
4x + 11x - 2 + 17 = 90
15x + 15 = 90
• Subtract 15 from both sides:
15x + 15 - 15 = 90 - 15
15x = 75
• Divide both sides of the equation by 15:

The diameter and height of the right circular one are equal, 2r = h.
Height of the pile is, h = 21 ft.
The objective is to find the rate of increase in height of the pile.
Explanation:
The general formula of volume of cone is,
[tex]V=\frac{1}{3}\pi r^2h\text{ . . . . . (1)}[/tex]From the given data, radius of the cone can be calculated as,
[tex]\begin{gathered} 2r=h \\ r=\frac{h}{2} \end{gathered}[/tex]Substitute the value of r in equation (1).

On plugging the obtained values in eqation (3),
