The clock shows 5 minutes to 8 in the morning.
It is 12 minutes slow.
What time should it be?
First, you have to know that 5 minutes to 8:00 is 7:55.
"It is 12 minutes slow."
So the clock's 12 minutes behind, let's catch it up a bit. :)
7:55(am) + 12(mins) = 8:07(am)

be red?
Answer:
40% or 4/10
Step-by-step explanation:
If 4 out of the 10 marbles are red, you simply divide them (4/10).
Write 0.041 as a percent.

You could use rate reasoning because, one day is 405 miles traveled. It is 3,272 miles from Sacramento to Key West, and when you use rate reasoning, you can tell that it will take about 8 days from Sacramento to Key West (3 more days if your counting the 5 days that they have already traveled)

The sum of the first five terms of an arithmetic progression is 65/2.Also ,five times the 7th is the same as six times the second term . Find the first term and the common difference of the AP.
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
What is the nth term of an arithmetic sequence?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

O C. F(x) = x2 + 5
O D. F(x) = x2
Answer:
x^2
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).
What is Parabola?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).

José es el encargado de reunir dinero y comprar
las pizzas para la convivencia del 14 de febrero
de su salón. La promoción es de 2 pizzas por 150
pesos con ocho rebanadas cadauna. ¿Cuánto
dinero debe darle cada compañero del grupo de
52 alumnos si quieren comer 3 rebanadas por
persona?
Cada estudiante debe pagar 2.88 pesos para consumir 3 rebanadas.
Como determinar el monto a contribuir por cada estudiante en una convivenciaSi 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.

An educator is interested in the relationship between how many hours students spend doing homework and the scores earned on exams. He gathers data from 12 students and calculates the least-squares regression line to be ŷ = 68.4 + 1.46x, where ŷ is the score on an exam and x is the number of hours spent doing homework. The residual plot is shown.
Based on the residual plot, is the linear model appropriate?
No, the residuals are relatively large.
No, there is a clear pattern in the residual plot.
Yes, there is no clear pattern in the residual plot.
Yes, about half of the residuals are positive and half are negative
Based on the residual plot, the linear model is not appropriate because the residuals are relatively large.
What is a residual plot?
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.
