What is the probability of rolling 7 or a 5 on a single 10 sided dice

1 answer:

5 0

Here a "success" is "obtaining a 7 or a 5." Assuming that the 10-sided die is marked {1, 2, 3, ... , 9, 10}, there are 2 ways in which to get a "success" out of 10 possible outcomes. Thus, P(5 or 7) is 2/10, or 1/5, or 02.

Consider the sequence 130, 143, 156, 169, ... Write an explicit formula to represent the arithmetic sequence and use it to find

pantera1 [17]

Answer:

a(n) = 130 + (n-1) 13

13th term = 286

Step-by-step explanation:

We are given a sequence of numbers: 130, 143, 156, 169, ... and we are to write an explicit formula to represent the arithmetic sequence and use it to find the 13th term.

We know that the arithmetic sequence can be defined by:

$a_n=d(n-1)+c$

where $d$ = the common difference between consecutive terms ; and

$c$ = $a_1$

13th term:

$a_{13}=130+(12)13 = 286$

Therefore, the formula for this sequence will be a(n) = 130 + (n-1) 13 and 13th term is 286.

The Pythagorean Theorem

a^2+b^2=c^2
a=5
b=7
5^2+7^2=c^2
25+49=c^2--------------------c=(74)^0.5=8.60 inches

Since sin = opposite/hypotenuse
sin theta=5/8.60
sin theta=0.5814
