What is the value of the 9th term in the following geometric sequence?

earnstyle [38]

Answer: The correct option is (D) 196608.

Step-by-step explanation: We are given to find the value of the 9th term in the following geometric sequence :

3, 12, 48, 192, . . .

We know that

the n-th term of a geometric sequence with first term a and common ratio r is given by

$a_n=ar^{n-1}.$

For the given sequence, we have

first term, a = 3 and the common ratio, r is given by

$r=\dfrac{12}{3}=\dfrac{48}{12}=\dfrac{192}{48}=~~.~~.~~.~~=4.$

Therefore, the 9th term of the given sequence will be

$a_9=ar^{9-1}=3\times 4^8=3\times65536=196608.$

Thus, the required 9th term of the given sequence is 196608.

Option (D) is CORRECT.

For the formula F = 95K – 455.67, what is the value of K when F = 0?

Inessa [10]

Answer:

Step-by-step explanation:

<u>Equation Solving</u>

We are given the equation:

F = 95K - 455.67

We are required to find the value of K when F=0:

95K - 455.67 = 0

Adding 455.67:

95K = 455.67

Dividing by 95;

K = 4.8

The table below shows all of the possible outcomes for rolling two six-sided number cubes. A table with 36 possible outcomes. Th

barxatty [35]

The image is missing, we have attached the image.

Answer:

The of getting an even number in first and an odd number second is $\frac{1}{4}\ or\ 0.25$ .

Step-by-step explanation:

Given,

Total number of outcomes = 36

We have to find the probability of rolling an even number first and an odd number second.

Solution,

Firstly we will find out the possible outcomes;

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

So the total number of outcomes = 9

Now according to the formula of probability, which is;

$P(E)=\frac{\textrm{total number of possible outcomes}}{\textrm{total number of outcomes}}$

Now on putting the values, we get;

P(of getting an even number in first and an odd number second)= $\frac{9}{36}=\frac{1}{4}=0.25$

Hence The of getting an even number in first and an odd number second is $\frac{1}{4}\ or\ 0.25$ .
