No, the given sequence is not an arithmetic sequence.

What is Arithmetic Sequence ?

An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.

In the above question,

The sequence is 3,5/2,3/2,-3/2,...

Take the 2nd term and minus the 1st term.

Now take the 3rd term and minus the 2nd term.

We can clearly notice that the differences are not same. Hence there is no common difference and therefore it's not an arithmetic sequence

Suppose you have rolled a six-sided die fifty times and recorded the result of each roll.

a_sh-v [17]

Using it's concept, it is found that the relative frequency probability of rolling an even number based on this experiment is $\frac{11}{25}$ .

A relative frequency is the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

50 dices are thrown, hence $T = 50$ .
22 resulted in an even number, hence $D = 22$

The <u>relative frequency</u> is given by:

$f = \frac{D}{T} = \frac{22}{50} = \frac{11}{25}$

Dawn and abed each roll a standard die obtaining a random number from 1 to 6. if the probability that dawns number is larger tha

larisa [96]

Answer:

a+b = 12

Step-by-step explanation:

There are 36 possible outcomes for rolling two dice. Let A be the number rolled by Abed and D be the number rolled by Dawn. The sample space, in the format [A,D], of all of the possibilities in which Dawn's number is larger is:

[5,6]

[4,5] [4,6]

[3.4] [3,5] [3.6]

[2,3] [2.4] [2,5] [2.6]

[1,2] [1,3] [1.4] [1,5] [1.6]

There are 15 ways out of 36 possible ways of Dawn getting the higher number. In the simplest form:

$\frac{15}{36}=\frac{5}{12}=\frac{a}{b}\\ a+b = 5+12 = 17$
