thanks
Since the time to failure distribution is
exponential, the distribution is F (n) = 1 – e ^ (-x/48)
The probability of failure between months 60
and 72 is the same as the probability that the battery will fail in 12 months,
since the exponential distribution is memoryless F (12) = 0.221

Answer:
SA = 108 ft^2
Step-by-step explanation:
The front and back faces are triangles with 4 ft base and 3 ft height.
The three sides are rectangles with dimensions 4 ft by 8 ft, 8 ft by 5 ft, and 3 ft by 8 ft.
The surface area is the sum of the areas of the two triangles and the three rectangles.
SA = 2 * (1/2)(4 ft * 3 ft) + 4 ft * 8 ft + 8 ft * 5 ft + 3 ft * 8 ft
SA = 12 ft^2 + 32 ft^2 + 40 ft^2 + 24 ft^2
SA = 108 ft^2

Answer:
15a⁴b²-20a³b³+30a²b⁴
Step-by-step explanation:
3a²-4ab+6b²
so for 5a²b²
(5a²b²)(3a²-4ab+6b²)
=15a⁴b²-20a³b³+30a²b⁴
