The area of a trapezoid = 0.5h(a + b) where a and b are the lengths of the parallel sides
so here we have 0.5(8)(a + 12) = 144
solve for a
4(a + 12) = 144
4a + 48 = 144
4a = 96
a = 96/4 = 24
Answer:
5) a)(-4,-6) b) (4,2) c) (2,6) 6) (3,2)
Step-by-step explanation:
5) the solution is the points where the lines meet.
6) graphed the lines; the picture of the graph is attached below
The answer will be 24m^2
because you have to find the area first so : Length * width.
which equals 4. and then you multiply it by 6
because cube is made up of 6 perfect squares.
Answer:
Step-by-step explanation:
Answer:
Follows are the solution to the given points:
Step-by-step explanation:
In point a:
In this sense, describe what type of error I will be.
Type I error: to conclude that perhaps the mean bulb life would be less than three hours when it becomes (at least) 3 hours.
In point b:
Describe throughout this context what the Type II error becomes.
An error of type II: never assuming that its bulbs' mean lifetime is much less than 3 hours. three hours at least
In point c:
What error — type I and type II — would further impact the interaction between the manufacturer and the customer?
A Type II error is probably further problematic because it means that even the buyer will buy bulbs that do not last long.
