The total number of bicycles and tricycles that were at the race are; 34

In mathematics, we know that a basic algebraic operation is simply any one of the common operations of arithmetic, that includes addition, subtraction, multiplication, division, raising to a whole number power, and taking roots (fractional power).

Now, we are told that there were 34 riders that showed up. Now, this means if there were 34 riders then we obviously had 34 bicycles and tricyles.

Thus, since the race lasted for 90 weeks and we are not told that any new riders were brought with new bicycles or tricycles, then it means that it was the same number number of bicycles and tricyles that were used for the 90 weeks.

Answer: A is correct

Step-by-step explanation:

Process of elimination:

A: The trend line is a good fit because the total

vertical distance between the line and the

points in the plot is small. This is the correct choice because all the other options have been eliminated.

B: The trend line is not a good fit because the

number of points above and below the trend

line are not equal. Trend lines are used to show the average slope of data meaning that the number of points above or below does not matter.

C: The trend line is a good fit because the line

passes through at least one point in the plot. It is possible to create a graph that uses a trend line that doesn't pass through at least one point.

D: The trend line is not a good fit because there

is an outlier in the plot that does not follow the

patterns in the data. Just because one point is a little farther away than others, does not mean that a trend line is not a good fit.

A graph of this continuous exponential function f(x) is shown in the image attached blow. Also, the y-intercept is equal to: B. 3.

Mathematically, an exponential function can be modeled by using this equation:

f(x) = ab^x

The half-life of this substance is 150 days.

We need to find the time it takes for the substance to decay to 50% of its original amount. We can use the equation y = a(1/2)^(x/b), where a is the initial amount, y is the amount left after time x, and b is the half-life.

A sample of a certain substance decayed to 73.2% of its original amount after 300 days. Half-life can be calculated as follows:

Rearranging the equation, we get

x/b = log₂(y/a).

Plugging in the given values, we get

x/b = log₂(0.732/1)

= log₂(0.732).

Solving for x, we get

x = b*log₂(0.732)

= 300*log₂(0.732).

Since b is the half-life,

b = 300/log₂(0.732) = 150 days.

The question that would most likely help one understand this excerpt from Adam Smith's book The Wealth of Nations is, "how does self-interest result in societal benefit?"

The main argument of Adam Smith's The Wealth of Nations is that society benefits when each person pursues their own self-interest. He referred to this fulfillment's driving force as the "invisible hand."

"Consumption is the sole purpose of all production," said economist Adam Smith. It implies that the level of consumption affects the production of goods and services.

Adam Smith was one of the first thinkers of his era to assert that wealth is produced through labor that is productive and that people are driven by self-interest to make the best use of their resources. He argued that capital investments generated profits, and that capital is allocated to projects where the greatest profits can be realized.

An important element of sampling that should be reported in research reports is the response rate, which represents the number of people who participated in the study relative to the number of people who were sampled or invited to participate.

The response rate can be calculated by dividing the number of people who participated in the study by the number of people who were sampled or invited to participate and then multiplying the result by 100% to express it as a percentage.

A high response rate is generally considered to be desirable, as it indicates that a significant proportion of the people who were sampled or invited to participate in the study actually took part in it.

However, low response rates can be a concern, as they may indicate that the sample is not representative of the population being studied, or that the study may be subject to bias.

The equation of line is y = ( 2/3 )x + 2 where the slope m = 2/3

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( 3 , 4 )

Let the second point be Q = Q ( -9 , -4 )

Now , the slope of the line is ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( -4 - 4 ) / ( -9 - 3 )

A percentage simply has to do with the a value or ratio which can be stated as a fraction of 100. It should be noted that when we want to we calculate a percentage of a number, we simply divide it and then multiply the value that is gotten by 100. In this case, the percentage then refers to a component per hundred. The word percentage simply means per 100 and it is represented by %.

Here, Jocelyn estimates that a piece of wood measures 5.5cm when it's actually 5.62 cm. We simply want to calculate the percentage error which will be calculated thus:

The percent error of Jocelyn’s estimate will be:

= (Estimated measurement - Original measurement) / Original measurement × 100

Total number of sold tickets for a basketball game = 788

Total receipts for game = $1,400

Price of game tickets for an adults = $2.50/ticket

Price of game tickets for student = $1.25/ ticket

let us assume that total tickets sold to adults be "x".

Out of 788 , total tickets sold to students = 788 - x

Total money paid by adults = $2.50x

Total money paid by students = $1.25(778 - x)

Total money paid by adults and students will be equal to ($2.50x + $1.25(788 - x) ).

Total receipts for game is $1,400, so

$2.50x + $1.25(788 - x) = $1,400
