The percentage of customers who chose whole wheat bread with turkey are 19 %.
Given that:-
Percentage of customers who preferred white bread = 55 %
Percentage of customers who preferred turkey with white bread = 46 % of those who like white bread.
Percentage of customers who preferred ham with whole wheat bread = 55 %
We have to find the percentage of customers who chose whole wheat bread with turkey.
Let the total number of customers at the local sandwich shop be 100x.
Percentage of customers who preferred whole wheat bread = (100-55) % = 45 %
45 % of 100x = 45x.
Percentage of customers who preferred turkey with whole wheat bread = (100-58) % of 45x = 42 % of 45x.
42 % of 45x = 18.9x ≈ 19x.
19x is 19 % of 100x.

Using an exponential function, it is found that:
a) During the first five days, the population of organism A grew by a factor of 2^5.
b) During the next three days, the population of organism B decayed by a factor 2^(-3).
c) The expression for the total change is of 2².
What is an exponential function?An exponential function is modeled according to the following rule:
[tex]y = ab^x[/tex]
In which:
a is the initial value of the exponential function.b is the rate of change of the exponential function.For the first five days, the population doubles each day, hence the rate of change is of:
b = 2.
The growth factor will be of:
y = 2^5 = 32
During the next three days, the population cuts in half each day, hence the rate of change is of:
b = 0.5.
Then the decay factor is of:
y = (0.5)³ = (1/2)³ = 2^(-3).
Applying properties of exponents, over the entire period, the change in the population will be of:
2^5 x 2^(-3) = 2^(5 - 3) = 2².
As when we multiply two terms with the same base and different exponents, we keep the bases and add the exponents.

Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in 12 hour. At the airport, they exited the car and walked for 34 hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in 214 hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.Answer the following questions about Kiley’s trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that Kiley is at rest (that is, not moving).In this task, you will write the ratio of miles to hours for each leg of Kiley’s trip. You will then, express the ratio as a decimal number. Next, you will find the unit rate in miles per hour (mph) for each leg of the trip. If your unit rate includes a repeating decimal number, you must indicate which digits repeat (for example, write 0.3¯when the 3 repeats.) A description of each leg is listed below in parts A through F.
Given:
The car ride from Kiley's house to the airport.
Distance =24.3 miles.
Time =1/2 hour.
We know that
[tex]\text{Average rate =}\frac{\text{Distance}}{\text{time}}[/tex]Substitute Distance =24.3 miles and time =1/2 hour to compute the average rate of the car ride from Kiley's house to the airport.
[tex]=\frac{24.3\text{ miles}}{\frac{1}{2}\text{hours}}[/tex][tex]\text{ Use }\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}\times\frac{d}{c}\text{.}[/tex][tex]=24.3\times\frac{2}{1}\text{ miles per hour}[/tex][tex]=24.3\times2\text{ miles per hour}[/tex][tex]=48.6\text{ miles per hour}[/tex]Hence the average rate of the car ride from Kiley's house to the airport is 48.6 miles per hour.
2)
Given that they walked 3/4 hours to the waiting area and covered the distance of 1.2 miles.
Distance =1.2 miles.
Time =3/4 hours.
we know that
[tex]\text{Average rate =}\frac{\text{Distance}}{\text{time}}[/tex]Substitute distance =1.2 miles and time =3/4 hours to compute the average rate of the walk from the car to the waiting area by the gate, at the airport.
[tex]=\frac{1.2\text{ miles}}{\frac{3}{4}\text{ hours}}[/tex][tex]=1.2\times\frac{4}{3}\text{ miles per hour.}[/tex][tex]=\frac{1.2\times4}{3}\text{ miles per hour.}[/tex]Multiplying 1.2 and 4, we get 4.8
[tex]=\frac{4.8}{3}\text{ miles per hour.}[/tex]Dividing 4.8 by 3, we get 1.6

What in mathematics is probability?Probability refers to potential.This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events.
The likelihood is based on the range of potential outcomes. the total number of possible outcomes. As an illustration, since there is only one way to get a head and a total of two possible results, the likelihood of flipping a coin and getting heads is one in two. a tail or a head.
According to given data;
Let's look at the first few probabilities; we're going to do this in reverse order, in order to find a pattern:
P(O,O,O,AS)=39/52)*(38/51)*(37/50)*(1/49)
=(39*38*37/3!)/(52*51*50/3!)*1/49
P(O,O,AS)=(39/3)(52/3)×1/49
but we know that;
(n/2)=n(n-1)/2!
P,(O,O,AS) =(39/2)/(52/2) *1/50

The arc YZ represented in the diagram, its length is :
2π/3 or 4π/6
Explanation:A circle's arc can be formed by any two points on its circumference.
A circle's arc length (S) = r(θ), where r is the radius and theta is the central angle in radians.
Given WY = XZ = 6,
So YZ = TZ = 3radius
and m∠XY = 140°.
so, m∠YZ = 180° - 140°. (As a semicircle with a central angle of 180°.)
m∠YZ = 40°.
then, m∠YZ = (40/180)°×π rad.
m∠YZ = 2π/9 rad.
then, Arc length of YZ = = 3×(2π/9).
YZ = 6π/9.

Which function's graph has a vertex at (3, 5) and contains the point (5, 13)?
The equation y = 2x² - 12x + 23 describes the function graph that includes a vertex at (3, 5) and passes through the point (5, 13).
What does a parabolic equation look like in vertex form?The vertex of a parabolic equation is at the point and the vertex form is y = a(x - h)2 + k, where a, h, and k are constants (h, k).
How do you answer this dilemma?Find the function whose graph has the vertex at (3, 5) and passes through the point in the question (5, 13).
Assuming it to be a parabolic function, we know that a parabolic equation's vertex form is y = a(x - h)2 + k, where a, h, and k are constants, and the vertex is located at the position (h, k).
As the vertex of the necessary function is at the position (3, 5), we may substitute h = 3 and k = 5 to obtain the following equation in the above equation:
y = a(x - 3)² + 5
Now that we know that the graph passes through the point (5, 13), we can change the original equation to read:
13 = a(5 - 3)² + 5,
or, 13 = 4a + 5,
or, 4a = 13 - 5 = 8,
or, a = 2.
We obtain the following from the equation y = a(x - h)2 + k by inserting a = 2, h = 3, and k = 5:
y = 2(x - 3)² + 5,
alternatively, y = 2(x² - 6x + 9) + 5,
alternatively, y = 2x² - 12x + 18 + 5,
Alternatively, y = 2x² - 12x + 23.
As a result, the function graph with the vertex at (3, 5) and the point of intersection (5, 13) yields the equation y = 2x² - 12x + 23.
