The dataset is quantitative and continuous.
Quantitative data is gathered by measuring and counting. Qualitative data is collected by interviewing and observing. Quantitative data is analyzed using statistical analysis, while qualitative data is analyzed by grouping it in terms of meaningful categories or themes. Quantitative data is anything that can be counted or measured; it refers to numerical data. Qualitative data is descriptive, referring to things that can be observed but not measured—such as colors or emotions.
Discrete data and continuous data are both types of quantitative data. The main difference between them is the type of information they represent. Discrete data typically only shows information for a particular event, while continuous data often shows trends in data over time. The type of data that has clear spaces between values is discrete data. Continuous information is information that falls into a continuous series. Discrete data is countable. Continuous data is measurable. There are distinct or different values in discrete data.
Since calories may be represented by numbers, the data set calories burnt will always have a numerical value. So, it is a quantitative piece of information.
Second, if the data set is quantitative, please specify which subcategory.
Because the values in this case can have many values, the data is continuous. The outcome may range from the smallest value of the data set to its greatest value. As a result, it is ongoing.
Thus, the dataset is quantitative and continuous.

A bridge is made with segments of concrete 50 m long. If the linear expansion coefficient is 12 x 10^-6 (oc)^-1, how much spacing (in cm) is needed to allow for expansion during an extreme temperature change of 150 ^of?.
The amount of spacing needed to allow for expansion is 0.09 m
What is length?Length is the distance between two point.
To calculate the amount of spacing needed to allow for expansion, we use the formula below.
Formula:
ΔL = L₁-αΔTL₁............................... Equation 1Where:
ΔL = Change in length concreteL₁ = Original length of the concreteΔT = Change in temperatureα = Coefficient of linear expansivityFrom the question,
L₁ = 50 mΔT = 150 °Cα = 12×10⁻⁶ °C⁻¹Substitute these values into equation 1
ΔL = 50×150×12×10⁻⁶ °C⁻¹ΔL = 0.09ΔL = 0.09 mHence, the amount of spacing is 0.09 m.

Ari has a map with a scale of 1/2 inch represents 18 miles. To get between two cities on the map, she measures 4 inches. How far would that be in real life?
By using the given scale, we will find that the real distance between the two cities is 144 miles.
How to find the real distance?We know that in our map the scale is:
1/2 inch = 18 miles.
If we multiply that by 2 we get:
2*(1/2) inch = 2*18 miles.
1 inch = 36 miles
Now, if the distance in the map is 4 inches, then we need to multiply that by the scale:
4 inches = 4*( 1 inch) = 4*( 36 miles) = 144 miles.
The real distance is 144 miles.

There are 6 roads connecting form a to b. You need to go to b, get back to a, and go back to b. You cannot use one road more than once. How many possible ways to do this?
There are 6 roads connecting from a to b. You need to go to b, get back to a, and go back to b. There are 360 ways to complete this task.
What is the number of ways?Generally, If you need to go from a to b and back to a twice, you can think of this as going from a to b and back to a, and then from a to b and back to an again, without returning to b in between.
This means that you need to use two different roads for the first trip and two different roads for the second trip.

Answer: £18704.32.
Step-by-step explanation:
To increase a value by a certain percentage, you can use the formula:
New value = Original value + (Original value x (Percentage increase/100))
In this case, to increase £16470.45 by 13.5%:
New value = 16470.45 + (16470.45 x (13.5/100))
New value = 16470.45 + 2233.8675
New value = 18704.3175

find a formula for rn for the function f(x) = (3x)2 on [−1, 5] in terms of n.
The formula for for Rn is given as Rn = Σ 18/n (1 - 12i/n + 36i²/n²).
We are given the function f(x) = 3x² on the interval [-1, 5] . This gives
Δx =6/n and xi= -1 + 6i/n.
Therefore,
Rn = Σ f(xi) Δx
= Σ 3 (-1 + 6i/n)² 6/n
= Σ 18/n (1 - 12i/n + 36i²/n²)
The limit of a function in mathematics is a key idea in calculus and analysis regarding the behavior of that function close to a specific input.
Informally, a function f gives each input x an output f(x). If f(x) approaches L as x approaches input p, we say that the function has a limit L at that location. More specifically, any input that is sufficiently close to p when f is applied forces the output value arbitrarily close to L.
The concept of limit is specifically used in the various definitions of continuity. Roughly speaking, a function is continuous if all of its limits agree with the values of the function. The term "limit" is also used in the definition of the mathematical term "derivative," which in one-variable calculus refers to the maximum value of the slope of secant lines on a function's graph.

The wrong with following piece of mRNA, TACCAGGATCACTTTGCCA is that it contains T and not U. So, option(D) is right choice here.
Messenger RNA (mRNA) is present in DNA. DNA uses four bases in its code, adenine (A), guanine (G), cytosine (C) and thymine (T). RNA also uses four bases. However, instead of using "T" as DNA, it uses uracil (U). So, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'. A strand of DNA is a template strand that has a nucleotide sequence on it that is read by RNA polymerases. Rna polymerase reads the template strand and encodes the m-RNA using the base-pairing rule. According to the rule, adenine pairs with thymine and guanosine with cytosine. So if the template DNA reads TAC GTT ACG, RNA polymerase will read it as AUG CAA UGC. Since no thymine is present in RNA, it will code for U instead of T.

The linear equation in slope intercept form is expressed as;

b is the y-intercept or initial value
For the swim team, since the team increased by an average of 10 members per year, then;
Slope = 10
In 2010, they had 5 members and so; y-intercept = 35
Thus, the equation is; y = 10x + 35

devise a recursive algorithm to find a2n , where a is a real number and n is a positive integer.
A recursive algorithm to find a^2n, where a is a real number and n is a positive integer, is as follows:
Start with the input value of n.If n is equal to 1, return the value of a^2.If n is greater than 1, divide the value of n by 2 and store the result in a new variable m.Find the value of a^(2m) using the recursive algorithm with the input value of m.If n is even, return the value of a^(2m) * a^(2m).If n is odd, return the value of a^(2m) * a^(2m) * a.This algorithm uses the property of exponentiation that a^(2n) = (a^n)^2, and divides the problem of finding a^2n into a smaller subproblem of finding a^n. It takes advantage of the recursive nature of the problem by calling the same algorithm with a smaller value of n.
The time complexity of this algorithm is O(log n) as it divides the problem into half at each recursive step.
It should be noticed that this algorithm assumes that the input value of n is positive, otherwise it would be necessary to add a check for a negative value or zero.
