Answer:
Explained
Step-by-step explanation:
So I'm not sure if you mean by 3/4 or 3-4. But I'm going to assume that its 3-4 because 3/4 is greater than 3/5
3/5 is equal to 0.6 -> you can also find 0.6 by multiplying 3/5 * 2 on both sides which will be 6/10 which is 0.6
and 3-4 is - 1 (which is negative)
since 3/5 is positive and 3-4 is negative. You would know that this is true.
Answer:
0
Step-by-step explanation:
Given that:
The probability of event A = 0.4
i.e. P(A) = 0.4
The probability of event B = 0.5
P(B) = 0.5
Given that A and B are disjoint, then they do not have any elements in common. Thus, the probability that both events will occur is;
P(A ∩ B) = empty set {}, and the cardinality of the intersection of these two disjoint sets are, therefore, zero (0).
Answer:
(a) 
(b) 
(c) Maximum area
square meters
Step-by-step explanation:
(a)
Given:
Total length for fencing = 160 m
Width of the rectangle = 
m.
Let the other length of the rectangle be 
m.
Then, from the figure,
Now, area of a rectangle is equal to the product of its length and width.
So, area is, 
(b)
Given:
For maximum area, derivative of area with respect to must be 0.
So, 
Therefore, for maximum area, .
(c)
Given:
Maximum area occurs at 
. Plug in 40 for in 
expression. This gives,
Maximum area is,
Therefore, maximum area is 3200 square meters.
