Answer:
Carlos.
Step-by-step explanation:
Dado que Simón y Carlos tienen una pista de autos iguales, pero cada uno de ellos tiene dos autos que corren a distintas velocidades, y de los autos de Simón uno le da una vuelta completa a la pista en 31 segundos y el segundo lo hace en 17 segundos, mientras que de los autos de Carlos uno da una vuelta completa en 36 segundos y el segundo en 42 segundos, si ambos proponen una competencia en la que todos los autos salen al mismo tiempo de la meta y el ganador será el primero en el que sus dos autos lleguen al mismo tiempo, de nuevo a la meta, para determinar quién ganará se deben realizar los siguientes cálculos:
Simón: 527 SEGUNDOS
A: 31 + 62 + 93 + 124 + 155 + 186 + 217 + 248 + 279 + 310 + 341 + 372 + 403 + 434 + 465 + 496 + 527
B: 17 + 34 + 51 + 68 + 85 + 102 + 119 + 136 + 153 + 170 + 187 + 204 + 221 + 238 + 255 + 272 + 289 + 306 + 323 + 340 + 357 + 374 + 391 + 408 + 425 + 442 + 459 + 476 + 493 + 510 + 527
Carlos: 252 SEGUNDOS
A: 36 + 72 + 108 + 144 + 180 + 216 + 252
B: 42 + 84 + 126 + 168 + 210 + 252
Por lo tanto, el ganador será Carlos.

Write a polynomial of least degree with roots 1 and 2.
Answer:
f(x) = x^2 - 3x + 1.
Step-by-step explanation:
If the roots of this polynomial are 1 and 2, the corresponding factors are (x - 1) and (x - 2). Multiplying, we get
f(x) = (x - 1)(x - 2) = x^2 - 3x + 1
The polynomial of least degree with roots 1 and 2 is f(x) = x^2 - 3x + 1.

The measure of the angle x will be 65°. Then the correct option is B.
What is an angle?Corresponding angle – If two lines are parallel, then the third line. The corresponding angles are equal angles.
Linear angle – If the total of two angles is 180 degrees, they are said to be linear angles.
Let y be the corresponding angle of x and linear pair of 115°.
∠y + 115° = 180°
∠y = 65°
Then the angle y and angle x are corresponding angles. Then we have
∠x = ∠y
∠x = 65°
Then the correct option is B.
The complete question is given below.

A company has the pay scales below , with the percent of employees receiving that pay listed. Find the best value to represent an average salary at this company. ( round to the nearest dollar ) Job Salary Percent of Employees Entry 23,264 60% 47,480 38% 117,027 2%
Answer:
$34,341
Step-by-step explanation:
Given :
Job Salary Percent of Employees Entry 23,264 60% 47,480 38% 117,027 2%
To obtain the best value for the mean salary ; we obtain the weighted average ;
Σ(salary * weight factor) / Σ weight
[(23264 * 0.60) + (47480 * 0.38) + (117027 * 0.02)] ÷ (0.60 + 0.38 + 0.02)
= 34341.34 / 1
Average salary = 34341.34
= $34,341 ( nearest dollar)
Find the equation of the line that passes through the points (4,
11) and (-1,1). Write your answer in slope-intercept form. Bonus points for
writing it in the two other forms (make sure you label which form is which).
Step-by-step explanation:
the slope = (1-11)/(-1-4) = -10/(-5) = 2
the equation is : y -11 = 2(x-4)
=> y -11 = 2x -20
y = 2x -8 +11
y = 2x +3
other forms :
<=> 2x - y = -3
<=> 2x - y + 3 = 0

Step-by-step explanation:
Complete question
A chocolate chip cookie manufacturing company recorded the number of chocolate chips in a sample of 50 cookies. The mean is 23.33 and the standard deviation is 2.6. Construct a 80% confidence interval estimate of the standard deviation of the numbers of chocolate chips in all such cookies.
Solution
Given
n=50
x=23.33
s=2.6
Alpha = 1-0.80 = 0.20
X^2(a/2,n-1) = X^2(0.10, 49) = 63.17
sqrt(63.17) = 7.948
X^2(1 - a/2,n-1) = X^2(0.90, 49) = 37.69
sqrt(37.69) = 6.139
s*sqrt(n-1) = 18.2
[tex]s\sqrt{\frac{n-1}{X^2 _{(n-1), \frac{\alpha }{2} } }[/tex] [tex]\leq \sigma \leq s\sqrt{\frac{n-1}{X^2 _{(n-1), 1-\frac{\alpha }{2} } }[/tex]
confidence interval:
(18.2/7.948) < S < (18.2/6.139)
2.290 < S < 2.965
The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = 1/4(x - 8). What
iS the slope-intercept form of the equation for this line?
O y = 1/4x- 12
O y= 1/4x-4
O y= 1/4x+2
O y= 1/4x+6
Answer:
3rd option
Step-by-step explanation:
The equation of a line in point slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Given
y - 4 = [tex]\frac{1}{4}[/tex] (x - 8)
with m = [tex]\frac{1}{4}[/tex] and (a, b) = (8, 4 )
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then
y = [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute (8, 4) into the partial equation
4 = 2 + c ⇒ c = 4 - 2 = 2
y = [tex]\frac{1}{4}[/tex] x + 2 ← equation in slope- intercept form

Step-by-step explanation:
volume of a cuboid = length * breadth * height
= 2*1*1
=2 [tex]ft^{3}[/tex]
Answer:
The volume of container is 2 ft ³.
Step-by-step explanation:
We have,
Length = 1 ft .Breadth = 1 ft.Height = 2 ft.We have Formula, Volume of Cuboid.
[tex] \small \sf \mapsto \: Volume = length × breadth × height[/tex]
substitute the values
[tex] \small \sf \mapsto \: Volume = 1 ft × 1 ft × 2 ft[/tex]
multiply the values
[tex] \small \sf \mapsto \: Volume = 2 \: ft {}^{3} [/tex]
Hence, the volume of container is 2 ft ³.

Find the measure of the missing angles to name the shortest and longest sides. (2x) x+15) 1. X= 2.
Answer:
KINDLY CHECK EXPLANATION
Step-by-step explanation:
The triangle Given is right angled :
Hence, the sum of the two angles = 90°
Hence, 2x + (x + 15) = 90
2x + x + 15 = 90
3x = 90 - 15
3x = 75
x = 75 / 3
x = 25
2x = 2 * 25 = 50
(x + 15) = 25 + 15 = 40
Hence, largest angle = angle Y
Largest side = side opposite largest angle = AD
smallest angle = (x + 15) = 40
Smallest side = side opposite smallest angle = AY

What is the explicit formula for the sequence 10, 15, 22.5, 33.75, …?
Answer:
Step-by-step explanation:
Since there's no one one number you can add to one number in the sequence to get to the next number, this is not arithmetic. It must be geometric. We need then to find the common ratio. Let's start with the first 2 numbers, find a ratio, and then use it to test for accuracy.
10x = 15 and
x = [tex]\frac{15}{10}=\frac{3}{2}[/tex] If this is in fact a geometric sequence witha common ratio of 3/2, we should be able to multiply 15 by 3/2 to get to the next number in the sequence. Let's try it out:
[tex]15(\frac{3}{2})= \frac{45}{2}=22.5[/tex] Good. So the common ratio is 3/2. The formula for an explicit geometric formula is
[tex]A_n=a_1(r)^{n-1[/tex] where a1 is the first number in the sequence and r is the common ratio. Filling in:
[tex]A_n=10(\frac{3}{2})^{n-1[/tex]
