(3) 8
Step-by-step explanation:
Note that ∆ADE is similar to ∆ABC. As such, the ratios of their legs are equal. Also note that AD = AB + BD.
BC/AB = DE/AD
BC/10 = 12/(10 + 5) = 12/15 = 4/5
or
BC = 10(4/5) = 8
Answer:
Length=15cm
Hope this answer is right!!
Step-by-step explanation:
Length be 3 cm longer than the breadth.
So, x=y+3
Perimeter = 2(x+y)54
So, x+y=27 =>x=15
x-y=3 =>x=12
So, length is 15 cm
The bottom layer of a decision tree provides information on: D. How all the connected factors lead to a final decision or outcome.
<h3>What is a decision tree?</h3>
A decision tree can be defined as a tree-like model that is used by mathematicians (statisticians) or researchers as a decision support tool, so as to graphically display decisions with respect to their potential outcomes, consequences, utility and resource costs.
This ultimately implies that, it is used for making decisions in business management or computer programming by graphically displaying all the possible (expected) outcome of a decision in layers.
In conclusion, the bottom layer of a decision tree provides information on how all the connected factors lead to a final decision or expected outcome.

Answer:
<h2>In this case,the answer would be option d) given in the answer choices or options or A two-sample t-test for a difference between population means.</h2>
Step-by-step explanation:
- In Statistics,a two sample test is generally used to examine or compare two different population means with the main objective to verify whether the population means are equal or otherwise.
- The two sample t-test basically involves the hypothesis testing to determine or verify the equality between two concerned population means.
- In this case,the two different populations of raccoons are given and the equality of the mean sample weights of the two distinct populations can be determined or evaluated by employing the hypothesis testing method under a two sample t test for measuring difference in two population means.
Answer:
12P3 = 1320
Step-by-step explanation:
How you need select three persons of a group of twelve persons, but in the selection each member of the group has a different position, then you need use a permutation
Permutation is defined how
In our case n = 12 and r = 3
Thus
12P3 = 1320
