Which number is the common difference of the sequence -92,-74,-54,-38,-20?
Mkey [24]
The common difference if there is one is the constant difference that occurs between any term and the term before it.... in this case:

There is no common difference, 

dx=18,20,16,18  the difference or velocity is not constant...

d2x=2, -4,2  the acceleration is not constant...

d3x=-6,6  the thrust is not constant  

Now we might be tempted to say that:

d4x=12 and say that that is constant and we COULD make a quartic equation fit all the data points, but without further data points in the sequence there is no mathematical proof that the quartic equation would produce accurate data points outside of the range given...

And solving a system of five equations for five unknowns is tedious for such a problem...a^4+bx^3+cx^2+dx+e=y

A coin is tossed twice. What is the probability of getting a tail in the first toss and a tail in the second toss?
skelet666 [1.2K]

Answer:

<h2>1/4 Chances</h2><h2>25% Chances</h2><h2>0.25 Chances (out of 1)</h2>

Step-by-step explanation:

Two methods to answer the question.

Here are presented to show the advantage in using the product rule given above.

<h2>Method 1:Using the sample space</h2>

The sample space S of the experiment of tossing a coin twice is given by the tree diagram shown below

The first toss gives two possible outcomes: T or H ( in blue)

The second toss gives two possible outcomes: T or H (in red)

From the three diagrams, we can deduce the sample space S set as follows

          S={(H,H),(H,T),(T,H),(T,T)}

with n(S)=4 where n(S) is the number of elements in the set S

tree diagram in tossing a coin twice

The event E : " tossing a coin twice and getting two tails " as a set is given by

          E={(T,T)}

with n(E)=1 where n(E) is the number of elements in the set E

Use the classical probability formula to find P(E) as:

          P(E)=n(E)n(S)=14

<h2>Method 2: Use the product rule of two independent event</h2>

Event E " tossing a coin twice and getting a tail in each toss " may be considered as two events

Event A " toss a coin once and get a tail " and event B "toss the coin a second time and get a tail "

with the probabilities of each event A and B given by

          P(A)=12 and P(B)=12

Event E occurring may now be considered as events A and B occurring. Events A and B are independent and therefore the product rule may be used as follows

        P(E)=P(A and B)=P(A∩B)=P(A)⋅P(B)=12⋅12=14

NOTE If you toss a coin a large number of times, the sample space will have a large number of elements and therefore method 2 is much more practical to use than method 1 where you have a large number of outcomes.

We now present more examples and questions on how the product rule of independent events is used to solve probability questions.

.In which situation could the quotient of
saveliy_v [14]

Answer:

Option D -  8 children

Step-by-step explanation:

Twenty four divided by eight the equation is irelated to which MCQ

24/3 = 8

Option D, A cookie jar contains 24 cookies. Each child receives 3 cookies.

The right answer is 24 cookies that are in a jar eaten by children,

If each child get 3 cookies,  

Hence, 24/3 the answer will be = 8

Means 8 children are there to eat 3 cookies that is 24.

What are 3 complex fractions that simplify to 1/4??
Aleksandr-060686 [28]
<span>Give 3 complex fractions that simplify to ¼
Complex fractions are bigger fractions that can be simplified into smaller fractions.</span> <span>=> First is 15 / 60
     15/60 = 1 /4
=> second is 50/200
50/200 = 1 / 4
=> Third is 43/172
43/172 = 1 / 4

There are many possible answer. There are infinite complex fractions that can be simplified to 1 /4. I only gave 3 examples to show how simplified fraction works.</span>
