Answer:

240.625

Step-by-step explanation:

Circumference = 55 m. = 2pi*r

Radius of enclosure, r = 55/(2pi)

Area of enclosure

= pi (r^2)

= pi (55/2pi)^2

= 55^2/(4pi)

=3025/4pi

substitute pi = 22/7

= 1925/8

= 240.625

The probability distribution for a
Katyanochek1 [597]
<h3>Answer:  0.17</h3>

This is the probability that corresponds to x = -5, which is less than x = -3, and it's the only x value of the list smaller than -3. There's not much else to say about this.

If we wanted to find something like P(X < -2), then we would add up the probabilities for x = -5 and x = -3 to get 0.17+0.13 = 0.30

3/11 de una caja contiene 18 galletas, cuantas galletas contiene una caja?
Fynjy0 [20]

Answer:

66 galletas

Step-by-step explanation:

Si 3/11 de una caja contiene 18 galletas entonces matematicamente significa que:

\frac{3}{11}g=18

Donde g son las galletas, ahora vamos a aislar la variable g:

\frac{3}{11}g=18\\\\(\frac{11}{3}) \frac{3}{11} g=18 (\frac{11}{3})\\\\g= \frac{198}{3}=66

Entonces una caja contiene 66 galletas

Help me with #4
Sladkaya [172]

Step-by-step explanation:

a. lim(x→2) [g(x) + h(x)]

Use additive property of limits.

= lim(x→2) g(x) + lim(x→2) h(x)

= 0 + 5

= 5

b. lim(x→2) [3 h(x)]

Use multiplication property of limits.

= [lim(x→2) 3] [lim(x→2) h(x)]

= 3 lim(x→2) h(x)

= 3 (5)

= 15

c. lim(x→2) [g(x) h(x)]

Use multiplication property of limits.

= [lim(x→2) g(x)] [lim(x→2) h(x)]

= (0) (5)

= 0
