Mathematics

Stels [109]3 years ago

Answer: D

Step-by-step explanation: An arithmetic sequence is a pattern in which the same number is repeatedly added which means that the difference between consecutive terms is constant and this is referred to as the common difference.

A. would not be an arithmetic sequence because the difference between the terms is not the same. For example, the difference between 2 and 5 is 3 and the difference between 5 and 10 is 5.

B. would not be an arithmetic sequence for the same reason as the first choice. The difference between the terms is not the same.

C. would not be an arithmetic sequence for the same reason as the first and second choices. The difference between the terms is not the same.

D. would be an arithmetic sequence because we add the same number to reach the next term in the sequence.

So to get from -4 to -7, we add -3. to get from -7 to -10, we add -3. To get from -10 to -13, we add -3 and so on.

This is a polygon. I need help finding the missing angle ?
QveST [7]
First find how much the sum of interior angles measure:

180(n-2)

(n is the number of sides)

180 (5 - 2)
180 (3)
540

Now add all the angles and set them equal to 540.

87 + 105 + 135 + 92 + x = 540
419 + x = 540
x = 121

Hope this helps :)

A spinner is divided into four equal sections labeled 1, 2, 3, and 4. Another spinner is divided into three equal sections label
Romashka-Z-Leto [24]
Since we are asked to compute the probability of two event with "or"
statement,  then we will add the probabilities like this:
Denote A the first event and B the second event:
P(A\cup B)=P(A)+P(B)
A="Get an even number":
P(A)= \frac{2}{4}= \frac{1}{2}
B="Get section B":
P(B)= \frac{1}{3}
Conclusion:
P(A\cup B)=P(A)+P(B)= \frac{1}{2} +\frac{1}{3}\\=\frac{5}{6}
The probability is 5/6
