Step-by-step explanation:
77+5=82 or 77-5=72
so he is within the range of 72-82
80+7=87 80-7=73
so he is also within the range of 73-87
Since both Kyle and Caleb scored 1 standard deviation above their respective class means, we can conclude that their performances were relatively equal.
What is standard deviation?A standard deviation is a measure of how far apart the data is from the mean.
A low standard deviation indicates that data is clustered around the mean, whereas a high standard deviation indicates that data is more spread out.
To determine whose performance was better relative to their class, we need to calculate their z-scores, which tell us how many standard deviations a particular score is from the mean.
For Kyle in Class A:
z-score = (82 - 77) / 5 = 1
This means that Kyle's score is 1 standard deviation above the mean for his class.
For Caleb in Class B:
z-score = (87 - 80) / 7 = 1
This means that Caleb's score is also 1 standard deviation above the mean for his class.
Thus, we can conclude that Kyle and Caleb's performances were comparable because they both scored one standard deviation above their respective class means.

John is performing an experiment in which a solution alternates between a clear color and a bluish-purple color at a regular time interval. He observes that the time interval between color changes is 30 seconds (s). Sally replicates the experiment with the same solution, but at a temperature that is 10 degrees Celsius (°C) higher. What is the most likely time interval between color changes at this higher temperature?
Answer:
15 seconds
Step-by-step explanation:
The given parameters for the experiment are;
The time it takes the solution to change from a clear color to a bluish-purple color at a given temperature = 30 seconds
The temperature at which Sally replicates the experiment with the same solution = 10°C higher than the temperature the experiment was carried out by John
Given that the process involves a change in color, which is a characteristic of a chemical reaction, and that the rate of a chemical reaction increases as the temperature of the reacting system is increased, we have time it takes for the solution to change color at a temperature increased by 10°C, will be a time lesser than 30 seconds

solve nt+6-xt=s for t
Answer:

What is Mathematical function ?
Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.
In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.
Given equation is nt+6-xt=s
Now solving for t by separately variables and constant :
nt+6-xt=s
t(n-x) = s-6
t = (s-6)/(n-x)
Therefor the value of t after arrangement is t = (s-6)/(n-x)

Find the inverse for this relation: { (1, -3), (-2, 3), (5, 1), (6, 4) }
Answer:
(-3,1), (3,-2), (1,5), (4,6)
Step-by-step explanation:
For finding and inverse of a relationship, you simply just need to swap the x and y values. So the x will go into the y value and the y value will go into the x value.
The inverse relation for the given relation is {(-3, 1), (3, -2), (5, 1), (6, 4)}.
What is relation?A relation in mathematics can be defined as a set of a pair of elements belonging to each set. It is also called as a mapping from one set to the other.
The given relation is { (1, -3), (-2, 3), (5, 1), (6, 4) }.
The domain of the given relation is set of all the first elements of each pair and the range is the set of all the second elements of each pair.
The range and domain set can be written as,
Domain = {1 , -2, 5, 6 }
Range = {-3, 3, 1, 4}
In order to find the inverse relation the domain and range sets sre interchanged.
Thus, the inverse relation for the given relation can be written as,
{(-3, 1), (3, -2), (5, 1), (6, 4)} .
Hence, the inverse relation is given as {(-3, 1), (3, -2), (5, 1), (6, 4)}.

Monica uso 1,2 litros de leche para hacer 12 flanes iguales ¿cuantos litros de leche necesitaria para hacer 60 flanes? ¿cuantos flanes haria con 0,5 decalitros de leche?
Answer:
1. 6 L de leche.
2. 50 flanes.
Step-by-step explanation:
1. Determinación del volumen (en litros) necesario para realizar 60 natillas.
De la pregunta dada arriba,
Monica usó 1.2 L de leche para hacer 12 natillas iguales.
Por lo tanto, usará xL de leche para hacer 60 natillas, es decir
xL de leche = (1.2 × 60) / 12
xL de leche = 6
Por lo tanto, necesitará 6 L de leche para hacer 60 natillas.
2. Determinación del número de flanes (natillas) que se pueden producir utilizando 0,5 decalitros de leche.
Empezaremos por convertir 0,5 decalitros (deca) a litro (L).
Esto se puede obtener de la siguiente manera:
1 deca = 10 L
Por lo tanto,
0.5 deca = 0.5 deca × 10 L / 1 deca
0,5 deca = 5 L
Por tanto, 0,5 deca equivale a 5 L.
Finalmente, determinaremos el número de flanes (natillas) que se pueden obtener a partir de 0.5 deca (es decir, 5 L) como se muestra a continuación:
Monica usó 1.2 L de leche para hacer 12 natillas iguales.
Por lo tanto, usará 5 L de leche para producir = (5 × 12) /1.2 = 50 natillas
Por lo tanto, puede hacer 50 flanes (natillas) usando 0.5 deca (es decir, 5 L).

The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of variation in this scenario?
Answer: 16 acres
Step-by-step explanation: we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x ----> the number of acres
y ---> total operating costs
we have the ordered pair (20,551,520)
For x=20 acres, y=$551,520
Find the value of the constant of proportionality k
substitute the values of x and y
The linear equation is equal to
Find out how many acres are on a farm with a total operating cost of $441,216
