Predict how many times you will roll a number less than 3 if you roll a standard number
Korvikt [17]

Answer:

about 117 times

Step-by-step explanation:

No. of possible outcomes of a cube: 6

2 out the 6 possible outcomes are less than 3,

and therefore, No. of favorable outcome: 2

P(less than 3)= No. of favorable outcome / No. of possible outcomes

                     =2/6 => 1/3

if you roll a standard number  cube 350 times then,

Prediction= number of rolls x (P(less than 3))

                =350 x 1/3

                ≈117 times.

The area of a square bedroom is 144 square feet. what is the length of one wall?
Rufina [12.5K]
The answer is:  "12 feet" .
________________________________
Note:  In a square, the length of EACH of the four sides of the square is the same.

Area = Length * width. 

For a square, length = width.

So for a square, Area = length * width = (length of a side)² = s² ,

Given:  A = s² = 144 ft² ;

Solve for the positive value of "s" .
________________________________
  →  s² = 144 ft² ;  Take the "square root" of each side ;

  → √(s²) = √(144 ft²) ;

  →   s = 12 ft.
_______________________________
The answer is:  12 ft.

To find the x intercept set y = 0 and solve for x

Y=3/4x - 6

6 = 3/4x

4/3 *6 = 4/3*3/4x
