4 0

Answer:

0.84

Step-by-step explanation:

From the given histogram we can state that

  • P(x=1)=0.32;
  • P(x=2)=0.24;
  • P(x=3)=0.28;
  • P(x=4)=0.16.

Note that the probability

P(1\le x\le 3)=P(x=1)+P(x=2)+P(x=3)=0.32+0.24+0.28=0.84.

Represent the geometric series using the explicit formula. 3, −6, 12, −24, … f(n) = 3 ⋅ (2)(n−1) f(n) = 3 ⋅ (−2)(n−1) f(n) = f(n
mr Goodwill [35]

Answer:

f(n)=(-2)(n-1)

Step-by-step explanation:

Each term of this Geometric Series (3, −6, 12, −24, ...) can also be found through this explicit formula: f(n)=(-2)(n-1) Because the n^{th} term is found by the product of its common ratio "q", times its predecessor n-1. Where n, refers to the order of the term.

So let's test it, suppose we want to find the 4th term. We know the common ratio and the first term. Then we can write f(n) as:

\\f(n)=3(-2)^{n-1}

f(4)=f(3)*-2⇒-24=12*-2⇒-24=-24

The explicit formula is ok.

A die is thrown . find the probability of (1) a multiple of 2 or 3​
tangare [24]

Answer:

A die is thrown which means that it can land on either 1-6 on the die.So if you want to find the probability of the multiple of 2 or 3....we have multiplies of 2 in the die from 1-6 which is 2,4 and 6 if you count them they are just 3 numbers and since there is a probability of it to land on any of them it will be 3/6 which is 1/2 if yiu divide by 3 to it's lowest term....Then multiple of 3 is 3,and 6.which will be 2/6 which is 1/3 if u cut to its lowest term. Or in the question means addition sign in probability then it is 2 or 3 which is (1/2)+(1/3)=5/6.Thank you for the question
