Answer:
0.1728
Step-by-step explanation:
We know that the random variable, X, arises from a binomial experiment, besides n = 14 and p = 0.13, so, q = 1 - p = 1 - 0.13 = 0.87. For a particular value x, we can compute the probability P(X = x) as , therefore,
. You can copy and paste the next instruction in excel to find the answer =COMBIN(14, 3)*0.13^3*0.87^11
Answer:
°
Step-by-step explanation:
(The sum of angles on a triangle is
°)
(Angles of a straight line sums to
°)
Elimination can be used to find the value of one variable:
Now, the value of can be found by using substitution:
I hope this helps :)
Every ordered pair has a second number of -6, so the mapping with -6 as the sole number on the right is the appropriate mapping. A mapping is only <em>not a function</em> if it maps a number to two or more different values (as shown in the top diagram of your attachment).
The appropriate choice is not shown in your question. It would be the one attached below.
