Area of the base = 6 (1/2 x 4.3 x 5) = 64.5cm

Area of the top = area of the base = 64.5cm

Area of the 6 side rectangles = 6 x 5 x 11 = 330 cm

Total surface area = 64.5 + 64. 5+ 330 = 459 cm²

A rectangular flower bed is five feet longer than it is wide. its area is eighty-four square feet.

777dan777 [17]

Lets say w is the width of the flower bed. We can make an equation to find the area.
The length of the of the flower bed is (w+5) and the width is w.
To find the area we need to multiply the length(w+5) by the width(w) and set it equal to 84,
(w+5)(w)=84
w^2 +5w=84
Using the quadratic equation you get the solutions of 7 and -12. Since 7 is positive it is our width. Our length is 7+5 or 12.

The computer that controls a bank's automatic teller machine crashes a mean of 0.6 times per day. What is the probability that,

professor190 [17]

Answer:

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$
