The Great Wall is more than 20,000 kilometers long about 3/4 of it is considered properly preserved

1 answer:

7 0

97. The great wall is more than 20 000 kilometers long. And about ¾ of it is considered as properly preserved. I guess you are asking about the value of ¾ which is properly preserved in the said length of the great wall. => ¾ = 0.75 Thus, the formula would be like this: => 20 000 * .75 = 15 000 Thus, the ¾ value of great wall that is preserved is equals to 15 000 kilometers long,

Answer:

The expression that represents the given sequence is 5+6(n-1). Option C (not labeled).

Explanation:

<u>Arithmetic Sequences</u>

In an arithmetic sequence, each term can be obtained by adding or subtracting a fixed number to the previous term. That fixed number is called the common difference.

We are given the following sequence:

5, 11, 17, 23, 29, ...

Each term is located in a position starting from n=1. Let's test each option:

A For n=1 we should have the first term (5). Substituting n=1 into the general equation: 5+6(n+1) = 5+6(1+1) = 5+12 = 17. Since the resulting term is not 5, this option is incorrect.

B For n=1, 6+5(n+1)= 6+5(2)=16. This option is incorrect.

C (not labeled) For n=1, 5+6(n-1)=5+6(1-1)=5+0=5. The first term is correct. Let's test for the second term (n=2):

5+6(2-1)=5+6=11. Correct. For n=3

5+6(3-1)=5+12=17. Correct.

We can see the terms are increasing by 6, and the given sequence is also increasing by 6. Thus, This option is correct.

D For n=1, 6+5 (n-1)=6+0=6. This option is incorrect.

The chance that a positive response is obtained from Chicago fro program 1 is %. The chance that a positive response is obtained

igor_vitrenko [27]

Answer:

The chance that positive response obtained for program 1 is 65.90

And The chance that positive response obtained for program 2 is 87.50

Step-by-step explanation:

Given data as :

The positive response for program of different cities in percentage

Now, The positive response is obtained from Chicago for program 1 is 65.90

The total positive response for program 1 in % = 68.80

So, The chance that positive response obtained = 65.90

Again ,

The positive response is obtained from Chicago for program 2 is 87.50

The total positive response for program 1 in % = 81.70

So, The chance that positive response obtained = 87.50

Hence The chance that positive response obtained for program 1 is 65.90

And The chance that positive response obtained for program 2 is 87.50 answer

A spinner has two equal sections, one green and one orange. The spinner is spun three times, resulting in the sample space S = {

Lera25 [3.4K]

The probabilities are as follows

$\rm P(X =0) = \dfrac{1}{8} ,\ P(X =1) = \dfrac{3}{8}, \ P(X =2) = \dfrac{3}{8} , \ P(X =3) = \dfrac{1}{8}$

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A spinner has two equal sections one green and one orange.

The spinner is spun three times, resulting in the sample space (S) will be

S = {GGG, GGO, GOG, OGG, GOO, OGO, OOG, OOO}.

If the random variable X represents the number of times orange.

X = 0, 1, 2, 3

For X = 0, then the probability of not getting orange will be

$\rm P(X = 0) = \dfrac{1}{8}$
