Answer:

8 and a half hours

Step-by-step explanation:

Time arthur went to bed = 9:30 pm
Time arthur woke up = 6 am
Hours arthur was asleep = 24 - (9 and half + 6)
                                         = 24 - 15 and a half
                                         = 8 and a half

The first term and the common difference of the Arithmetic Progression which the given sum of the first 5 terms are respectively; 6 and 1/4

We are told;

Sum of first 5 terms of the AP = 65/2

Formula for sum of n terms of an AP is;

S = ⁿ/₂(2a + (n - 1)d)

65/2 = ⁵/₂(2a + 4d)

⇒ 65 = 5(2a + 4d)

13 = 2a + 4d     ------(1)

Formula for the nth term of an AP is;

aₙ = a + (n - 1)d

five times the 7th term is the same as six times the second term.

7th term is; a₇ = a + 6d

second term is; a₂ = a + d

Thus;

5(a + 6d) = 6(a + d)

5a + 30d = 6a + 6d

a = 24d

Put 24d for a in eq 1 to get;

13 = 2(24d) + 4d  

13 = 52d

d = 13/52

d = ¹/₄

Thus; a = 24(¹/₄) = 6

Speed = Distance / time

Distance is fixed so speed x time = constant

speed1 x time1 = speed2 x time2

speed1/speed2 = time2/time1

speed1/speed2 = 20/27

time2/time1 = 20/27

Percentage decrease in time = (time1 - time2)/time1 x 100%

= (1 - time2/time1) x 100%

= (1 - 20/27) x 100%

= 7/27 x 100%

= 25.9%

Let the equation of the angle bisector be y = mx + C

It is the angle bisector so its slope, m, is half way between slope of the two lines:

y = 2; slope = 0

y = 4x - 2; slope = 4

So m = (0 + 4) / 2 = 2

y = 2x + C

It is the angle bisector so the line must pass through intersection of the two lines:

y = 2 and y = 4x - 2

4x -2 = 2

x = 1

Intersection point is at x = 1 and y = 2

Substitute back into y = 2x + C

2 = 2(1) + C

C = 0

So the equation is y = 2x

Step-by-step explanation:

If it has the same shape, it has the same points, it has the same equation/expression.

The equation of the given graph is F(x) = x² - 5. The correct answer is an option (A).

A parabola is a U-shaped curve this is drawn for a quadratic function.

The graph of F(x) = x² - 5 is a parabola that opens upward and is shifted 5 units down compared to the graph of G(x) = x².

The vertex of the parabola is located at (0,-5) instead of (0,0) as it is for the graph of G(x) = x².

The shape of the parabola is the same as that of G(x) = x², but it is translated downward by 5 units.

This means that the minimum point (vertex) of F(x) is located 5 units below the minimum point (vertex) of G(x).

Thus, the correct answer is an option (A).

Based on the residual plot, the linear model is not appropriate because  the residuals are relatively large.

A residual plot is a graph that shows the residual values on the y-axis and fitted values on the x-axis. The aim of a residual plot is to check if the residual are consistent with random error.  When the residuals center on zero, it means that the model’s predictions are correct on average. If this is not the case, the model's predictions are not correct.

Cada estudiante debe pagar 2.88 pesos para consumir 3 rebanadas.

Si sabemos que existen 52 alumnos que quieren comer 3 rebanadas, entonces tenemos que el total requerido de rebanadas es de 156 rebanadas.

Además, si dos pizzas tienen 16 rebanadas y cuestan 150 pesos, entonces el número de rebanadas dividido por el par de cajas es 1.025 pares. Por ende, quedarían 4 rebanadas sobrantes que pueden ser compartidas por alguien más o vendidas a alguien más a cambio de una tarifa módica.

Por último, el monto a pagar por cada estudiante es el precio de la oferta dividido el número de estudiantes. En consecuencia, cada estudiante debe pagar aproximadamente 2.88 pesos.
