1 answer:
ZanzabumX [31]3 years ago
8 0

Answer:

1. False 2. True

Step-by-step explanation:

For a geometric sequence,

\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}

1. The sequence is :

3, 13, 23, 33,...

\dfrac{13}{3}\ne \dfrac{23}{13}

It is not geometric. It is false

2. The sequence is :

5, -25, 125, -625

\dfrac{-25}{5}=\dfrac{125}{-25}\\\\-5=-5

So, the sequence is geometric as the common ratio is same. It is true.

Rolling a Red and Yellow Dice
grandymaker [24]

Answer:

Option C 5/12 is correct option

Step-by-step explanation:

We have to find the probability that shows yellow dice has a larger value than the red dice.

Probability= total no of favorable outcomes / total no of outcomes

in our case, considering the data set, we have to find those pair where value of yellow die is greater than the red die. Where (1,2) represents 1 on the red die and 2 on the yellow die

(1,2) (1,3) (1,4) (1,5) (1,6)

     (2,3) (2,4) (2,5) (2,6)

              (3,4) (3,5) (3,6)

                       (4,5) (4,6)

                                (5,6)

These are the possibilities where yellow die has greater value than red die.

total no of favorable outcomes = 15

total no of outcomes = 36

probability that yellow die has greater value than red die = 15 / 36

                                                                                                = 5/ 12

Option C 5/12 is correct option

How should I solve for x and what is x?
algol [13]

Answer:

x =12

Step-by-step explanation:

We can use the Pythagorean theorem to solve for x

a^2 + b^2 = c^2

16^2 + x^2 = 20^2

256 +x^2 = 400

Subtract 256 from each side

256-256 +x^2 = 400-256

x^2 =144

Take the square root of each side

sqrt(x^2) =sqrt(144)

x = 12
