hope this helps :)

Answer:

(1,0) + 4 up and + 1 right

The answer is (2,4)

Answer:

i think they would be the same

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.

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.

[tex]t=\frac{s-6}{n-x}[/tex]

Step-by-step explanation:

[tex]nt+6-xt=s[/tex]

[tex]\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}[/tex]

[tex]nt+6-xt-6=s-6[/tex]

[tex]Simplify[/tex]

[tex]nt-xt=s-6[/tex]

[tex]nt-xt[/tex]

[tex]=t\left(n-x\right)[/tex]

[tex]t\left(n-x\right)=s-6[/tex]

[tex]\frac{t\left(n-x\right)}{n-x}=\frac{s}{n-x}-\frac{6}{n-x};\quad \:x\ne \:n[/tex]

[tex]t=\frac{s-6}{n-x}[/tex]

Therefor the value of t after arrangement is t = (s-6)/(n-x)

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)

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

so

For y=$441,216

substitute in the linear equation the value of y and solve for x

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).

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

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)}.

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)}.
