Answer:
0.139
Step-by-step explanation:
total = 43 + 56 + 16 = 115
country songs = 16
p(country song) = 16/115 = 0.139

Step-by-step explanation:
Frances had no money in her checking account. She writes 3 checks for $35 each. The bank imposes a $15 penalty because she has overdrawn her account. How much money is in her account now?
The money in Frances' account is - $ 120 after the 3 checks and the penalty.
We are given that:
Frances has no money in her account.
Current balance of her account = $ 0
Now she wrote 3 checks of $ 35 each.
Amount written = 3 × $ 35 = $ 105
Now, the balance in her account will be = $ 0 - $ 105 = - $ 105
Also, the bank has imposed a penalty of $ 15 as she has overdrawn her account.
So, the balance now will become:
Balance = - $ 105 - $ 15 = - $ 120
Therefore, the money in Frances' account is - $ 120 after the 3 checks and the penalty.

Flying Home A bird flies from the bottom of a canyon that is 59; feet below sea level to a nest that is 752 feet above sea level. What is the difference
10
elevation between the bottom of the canyon and the bird's nest?
*The values in the question and the image are different. It is solved below according to the image*
The correct answer is 812 and 2/5 feet.
Convert the mixed fraction into improper fraction.
Distance between the bottom of canyon and sea level = 59 and 9/ 10 feet= 599/10 feet
Distance between the bird's nest and sea level = 752 and 1/2 feet = (752×2 + 1) feet =1505/2 feet
So, the difference between elevation between the bottom of the canyon and the bird's nest = 599/10 + 1505/2 feet
= 59.9 + 752.5 feet = 812.4 feet
= 812 and 4/10 feet
= 812 and 2/5 feet
Hence, the difference between elevation between the bottom of the canyon and the bird's nest is 812 and 2/5 feet .

3. If f(x) = x² and g(x) = 3x - 1, find f(g(x))
Answer:
f(g(x)) = 9x² - 6x + 1
Step-by-step explanation:
We are told that:
• [tex]f(x) = x^2[/tex]
• [tex]g(x) = 3x -1[/tex].
In order to find [tex]f(g(x))[/tex], we have to replace [tex]x[/tex] in the definition of [tex]f(x)[/tex] with the definition of [tex]g(x)[/tex]. In other words, [tex]3x -1[/tex] has to be the input for [tex]f(x)[/tex]:
[tex]f(g(x))[/tex] = [tex]f(3x -1)[/tex]
⇒ [tex](3x - 1)^2[/tex]

If we want to have solutions for the linear equation, the value of A must be 4,
Which number should go in the box?Let's define A as the number that should be in the box, now we can write the linear equation in the image as:
A*(5x + 6) = 20x + 24
We want to find the value of A, if we divide both sides by 5x + 6 we will get:
A = (20x + 24)/(5x + 6)
The numerator can be rewritten as:
20x + 24 = 4*(5x + 6), replacing that we will get:
A = 4*(5x + 6)/(5x + 6) = 4
Then we conclude that, if we want to have solutions for the linear equation, the value of A must be 4.

In linear equation, $1.56 is the price of a pair of sport socks.
What in mathematics is a linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."To find how much it costs for one pair of socks, divide the cost with how many pairs there are.
12.55/8 = 1.56875
Since we are determining the cost of each pair of socks, it's only justifiable if we round it to the nearest hundredths.
Therefore, a pair of socks cost around $1.56 excluding taxes.

35. What is the equation of the line that is parallel to y = 4x + 3 and passes through the point (2, 6) ?
The equation of the line that is parallel to y = 4x ₊ 3 and passes through the point (2,6) is y = 4x ₋ 2.
The slope of the preceding equation is 4 because it is in slope intercept form. The slope of an equation is always equal for parallel lines, hence the slope of the equation we are requested to create is also 4. We are given that this line passes through (2,6).
In the absence of intersection, two lines are said to be parallel. Each line has the same slope. In the event where m₁=m₂, f(x)=m₁x+b₁ and g(x)=m₂x+b₂ are. parallel
In order to write in y = mx +b form, we need to solve for b (the y-intercept).
Given, x=2, y=6, and m = 4.
6 = (4) (2) ₊ b
simplify
6 = 8 ₊ b
solve for b.
b = 6 ₋ 8
b = ₋2
So the equation of the parallel line is y = 4x ₋ 2
Hence we get the equation of the line that is parallel to y = 4x ₊ 3 and passes through the point (2,6) is y = 4x ₋ 2

If Amanda distributed 62 pieces of gum among her friends by giving 2 to each friend and she has remaining 8 then we can say that she have 27 friends.
Given that Amanda won 62 pieces of gum and division has been done in such a way that 2 pieces to each friend are given and only 8 has remaining.
We are required to find the number of friends that Amanda have.
If 8 pieces of gums are left then the number of pieces distributed will be 62-8=54 pieces of gums.
Since 2 pieces are given to 1 friend so the number of friends will be=54/2=27 friends.

Joseph could use C), D), and E) to make kebabs without any leftovers:
C) 30 pieces of meat and 40 pieces of vegetables
D) 45 pieces of meat and 60 pieces of vegetables
E) 72 pieces of meat and 96 pieces of vegetables
How were the answers determined? To solve for the answer, here are some pointers:
Consider the given which states that each kebab has 3 pieces of meat and 4 pieces of vegetables, and Joseph wanted to make kebabs without any leftovers - meaning, there should be no extra piece of meat or no extra piece of vegetable.
In choosing which is the answer, make sure that the number of pieces of meat must be divisible by 3 (pieces of meat), and the number of pieces of vegetables must be divisible by 4 (pieces of vegetables). This was also based on the given.
Moreover, the quotient for meat and the quotient for vegetables must be equal to each other so that there will be no leftovers.
Therefore, the answers are C), D), and E) because these three answers satisfy the conditions above.

Using exponent properties, the equivalent expression is given as follows:

What is the equivalent expression?Two thirds to the fourth power is given by:
[tex]\left(\frac{2}{3}\right)^4[/tex]
Two thirds to the third power is given by:

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, hence:

(SOMEBODY PLEASE ANSWER THIS ALREADY) Lines a & m are parallel. Using the diagram below, what is the degree measure of angle 3?
Enter the numerical answer only. Example, if the answer is 12 degrees, only enter 12.
Based on the Alternate Interior Angles Theorem, the degree measure of angle 3 is equal to 153.
What are parallel lines?Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.
What is the Alternate Interior Angles Theorem?The Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent.
Since line a and m are parallel lines, angle 4 and 6 are alternate interior angles. Therefore, by applying the supplementary angle theorem, the measure of angle 6 is given by:
Q + R = 180°
153° + m<6 = 180°
Angle 6 = 180° - 153°
Angle 6 ≡ Angle 4 = 17°
Now, we can determine the degree measure of angle 3 by applying the supplementary angle theorem:
Q + R = 180°
17° + m<3 = 180°
Angle 3 = 180° - 17°
Angle 3 = 153°

The approximate location of the dolphin is 155 feet as it moves at the rate of 6.2 feet per second.
Rate in defined as the speed or the distance travelled by the dolphin in unit time.
rate or speed is calculated by dividing the distance travelled by the total time taken to cover that distance.The units of rate is given by unit of distance/unit of time .The units of rate are meter/second , miles/hour , feet/second etc..Velocity is defined as the rate in a specified direction. Velocity is a vector quantity while speed or rate is a scalar quantity.Given the rate of the dolphin is feet per second .
Time taken by the dolphin is 25 seconds.
∴ distance travelled is given by rate × time
Hence distance travelled is 6.2 × 25 = 155 feet
