A single die is rolled twice. Find the probability of rolling an oddnumber the first time and a number greater than 2 the second
harkovskaia [24]

Answer:

1/3.

Step-by-step explanation:

The 2 events are independent so we multiply the 2 probabilities.

Prob(rolling an odd number) = 3/6 = 1/2.

Prob(rolling a number greater than 2) = 4/6 = 2/3.

The required probability = 1/2 * 2/3

= 2/6

= 1/3.

Mr. Hernandez's backyard is shaped like a trapezoid with a height of 10 m, a top base of 15 m, and a bottom base of 19 m. In his
Zolol [24]
The area of the trapezoid is calculated through the equation,
                             A = 0.5(b₁ + b₂)h
where A is area, b₁ and b₂ are the lengths of the bases and h is the height. Substituting the known values,
                              A = 0.5(15 m + 19 m)(10 m)
                                   A = 170 m²
The area of the garden is 170 m².

nikdorinn [45]

Answer:

<h2>1.  14 in</h2><h2>2. 28 in.</h2><h2>3. 43 in</h2>

Step-by-step explanation:

   x          2x                        3x + 1

|---------|-------------------|---------------------------|

|<-------------------- 85 in ------------------------>|

85 = x + 2x + 3x + 1

85 - 1 = 6x

x = 84 / 6

x = 14

1st piece                   = 14 in

2nd piece = 2(14)     = 28 in

3rd piece = 3(14) + 1 = 43 in

                   ----------------------------

total                          =  85 in
