2. The total number of ski trails is 12. That's how many numbers there are in the box.

3. The difference in length between the longest ski trail and the shortest ski trail is the biggest number minus the smallest number in the box. 3 1/8 minus 1 3/8 is 1 and 3/4. So the answer is 1.75 or 1 3/4, whichever one works.

4. There are 3 trails that are 2 7/8 miles long. so You do 2 7/8 times three or 2 7/8 plus 2 7/8 plus 2 7/8. That equals 8 19/40 which is the answer. Ti add them together first turn them into mixed numbers. 2 7/8 is the same as 23/8. 8x3=24.  23x3=69. 69/24 is the same is 8 19/40 through further simplification.

5. 3 1/8 plus 1 3/8 is 4 1/2 or 4.5

6. The shortest ski trail is 1 3/8.   1 3/8 times 3 is 4.125. 4 is greater than 3 which means Sam is automatically right.

Answer:

1. See attached for dot plot

2. 12

3. longest ski trail = 3\frac14

  shortest ski trail = 1\frac38

  ⇒ difference = 3\frac14-1\frac38=1\frac78 miles

4. There are 3 trail that are 2\frac78 miles long.

   ⇒ total length = 3 \times 2\frac78=8\frac58 miles

5. Sum of shortest trail and longest trail = 3\frac14+1\frac38=4\frac58 miles

6. 3 times the shortest trail = 3 \times 1\frac38=4\frac18 miles

   longest trail = 3\frac14 miles

   Therefore, Eli is correct as 3\frac14

Find the slope of the line through each pair of points (20,-16),(19-16)
ale4655 [162]

Answer:

Undefined slope.

Step-by-step explanation:

The formula should be y2 - y1 over x2 - x1

Points ( 20,-16 ) and ( 19, -16 )

So ( -16 - ( -16 ) ) over ( 19 - 20 )

0 over -1

The slope is 0. Undefined.

Al obtener el valor de lo que costará la fiesta de graduación para tu grupo te das cuenta que el lugar que decidieron alquilar p
dybincka [34]

Explicación paso a paso:

Debemos buscar el costo de cada boleto y la cantidad de personas que deben ir.

Dada la función que da forma al comportamiento expresado como;

f (x) = (-2x) ^ 2 + 80x + 300 donde;

x es el costo de cada boleto

f (x) es el número de personas que deben ir

Para obtener x, usaremos la expresión;

x = -b / 2a

De la ecuación cuadrática dada, a = -2, b = 80 yc = 300

Sustituir;

x = -80/2 (-2)

x = -80 / -4

x = 80/4

x = 20

Por lo tanto, el boleto cuesta $ 20.

Lo siguiente es obtener la cantidad de personas que deben ir. Para conseguirlo, sustituiremos x = 20 en la expresión modelada como se muestra;

f (x) = (-2x) ^ 2 + 80x + 300

f (20) = (-2 (20)) ^ 2 + 80 (20) +300

f (20) = (-40) ^ 2 + 1600 + 300

f (20) = 1600 + 1600 + 300

f (20) = 3500

Por lo tanto, 3500 personas tienen que ir
