The first term in a sequence of numbers is 1/2

Andrei [34K]

Answer:

The correct answer is C. The 4th term is 11.

Step-by-step explanation:

Since the next term is one more than twice the previous, we can calculate it by the following expression:

$a_{n} = 2*a_{n-1} + 1$

So the second term is:

$a_2 = 2*\frac{1}{2} + 1\\a_2 = 2$

The third term:

$a_3 = 2*2 + 1\\a_3 = 5$

And the fourth term:

$a_4 = 2*5 + 1\\a_4 = 10 + 1 = 11$

The correct answer is C. The 4th term is 11.

Suppose that you are taking a T/F exam and you have no idea at all about the answers to the last three questions. You choose ans

podryga [215]

Answer:

0.375, 0.125, 0.5

Step-by-step explanation:

given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.

Probability for correct guess = 0.5 remains constant for each of the three questions

X - no of questions is binomial with n =3 and p = 0.5

1) the probability that you guessed right on exactly one of the three questions

= P(X=1)

= $3C1(0.5)^3 = 0.375$

2) the probability that you guessed right on zero of the three questions

= $P(X=0)\\= 0.5^3=0.125$

3) the probability that you guessed right on at least two of the questions

= $P(x=3)+P(2)\\= 1-0.5\\=0.5$

75 Points If You get This Right

NNADVOKAT [17]

Answer:

1. 2

2. 6

3. 2

4. 3

5. 1

6. 1

Step-by-step explanation:

First put the data in order from smallest to largest

2,2,2,3,3,6

The minimum is 2

The maximum is 6

The median is 2,2,2 ,3,3,6 is between the 2 and 3 (2+3)/2 = 2.5

The 1st quartile is 2,2,2 is the middle number = 2

The third quartile is 3,3,6 is the middle number is 3

The interquartile range is 3-2 =1

The mean average deviation is

First find the mean: ( 2+2+2+3+3+6)/6 =18/6 = 3

Then find how far each point is from the mean

(3-2) + (3-2) + (3-2) + (3-3) + (3-3) + (6-3) = 6

Divide this by the number of data points

6/6 =1

Very large or very small numbers are best input with exponential notation. For instance, the number 8,000,000 (eight million) is

Lerok [7]

Answer:

$9*10^{12}km$

Step-by-step explanation:

$9,460,730,472,580.8 km$

First, we can work out 5% of our number, by multiplying it by 0.05

$9,460,730,472,580.8 * 0.05 = 473,036,523,629$

Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.

$9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}$

We can see that $9*10^{12}$ is in the range of valid answers, as:

$8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}$

So, our final answer is:

$9*10^{12}km$

Cate solved an inequality to find c, the possible number of cats that a shelter can house. She found that c < 28. Which state

ASHA 777 [7]

Answer:

The shelter can house 17 cats because

17 < 28.

Step-by-step explanation:

We cannot have fractions of cats, and we cannot have a negative number of cats. So the third statement is reasonable because c < 28.
