The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,
A = bh / 2
where A is area, b is base and h is the height.
Substituting the known values,
A = (4 inch)(9 inch) / 2 = 18 in²
Multiplying this area by 4 will give us an answer of 72 in².
Then, we also calculate for the area of the square base.
A = s²
where s is the measure of each side of the square.
A = (4 in)² = 16 in²
Finally, we add up the calculated areas.
surface area = 72 in² + 16 in²
<em>surface area = 88 in²</em>
Hence, the surface area of the figure is equal to 88 in².
Answer:
Sammy is expected to lose $1.39 on average per roll
Step-by-step explanation:
Since Sammy is rolling two six-sided cubes, the number of possible outcomes is given by:
6 x 6 =36
Out of those 36 outcomes, only two would result in a sum of 3, rolling a 1 and 2 or a 2 and a 1. Therefore, the probability of winning (P(W)) and the probability of losing (P(L)) are:
The expected value is defined as the sum of the product of the likelihood of each event by its payout:
Sammy is expected to lose $1.39 on average per roll.
I could only do 3 loads of laundry.
$12.00/hr x 75 Minutes (1.25hrs) = $15.00
1 load of laundry costs $4.00
1 shift = $15.00 Earned / $4.00 per load = 3.75 loads of laundry
