Answer:

The experimental probability of rolling a 2 is \frac{1}{4}.

Step-by-step explanation:

Since you didn't give any statements, I'll make one myself.

P of rolling a 2 (experimental): \frac{15}{60} =\frac{1}{4}

The experimental probability of rolling a 2 is \frac{1}{4}.

Answer:

-1 and -3

(n+7)(n-8)

Step-by-step explanation:

1. Find the Zeros

f(x)=x^{2} +4x+3

f(x)=\left(x+1\right)\left(x+3\right)

x+1=0\\x=-1\\x+3=0\\x=-3

2. Factoring Trinomials

f(x)=n^{2} -n-56

f(x)=\left(n+7\right)\left(n-8\right)

n+7=0\\n=-7\\n-8=0\\n=8

A rectangular aquarium 3 ft. x 2 ft. 1 ft. is 2/3 full of water. In cubic feet, how much water is in the tank
tatuchka [14]

To find the volume of a rectangular prism, we must multiply the length * width * height.


In this case,


Volume = 3 ft * 2 ft * 1 ft

= 6 ft^3


Because this tank is 2/3 full with water, to find out how much water is in the tank, we must multiply 2/3 by the total volume of the tank (6 ft^3).


2/3 * 6 ft^3 = 4 ft^3


This means that there are 4 cubic feet of water in the tank.


Hope this helps!
