The height of a square pyramid-shaped gift box is one half the length of

Schach [20]

Answer:

15 inches

Step-by-step explanation:

Volume of a squre based pyramid :

V = a²(h/3)

a = base edge ; h = height

h =1/2 a

V = 4500

4500 = a² * (1/2a) ÷ 3

4500 = a² * a/2 * 1/3

4500 = a³/2 * 1/3

4500 = a³ / 6

27000 = a³

Take the cube root of both sides

(27000)⅓ = a

30 = a

Recall:

h = 1/2a

h = 1/2(30)

h = 15 inches

mixer [17]

Answer:

So, the probability is P=0.041.

Step-by-step explanation:

We know that 45% of people in Fast-Food restaurants order a diet drink with their lunch.

We conclude that the probaility p=0.45 that a person order a diet drink.

We calculate the probability that the fourth person orders a diet drink.

We get:

$P=p^4\\\\P=0.45^4\\\\P=0.041\\$

So, the probability is P=0.041.
