Answer: 40°
Step-by-step explanation:
You add 90° for the right angle and 50° for the other and subtract from 180°
B
una unidad de sentido, y es por medio de ellas que los hablantes logran expresar una proposición lógica
-11/8 because you turn the first one into -6/8 and then subtract to get -11/8
SOLUTION
Given the question in the image, the following are the solution steps to answer the question
STEP 1: Write the given details

STEP 2: Get the number of students that takes the subjects only
From the basic stuff, we have Number of candidates who had taken only each of the subjects

STEP 3: Represent the values above on a Venn Diagram after getting the values
STEP 4: Find the total number of candidate that sat for the exam.

Hence, the total number of candidates that sat for the exam is 276
Answer:
an = -6*(1/4)^(n-1)
Step-by-step explanation:
We have that the recursive formula for the given geometric sequence is:
a1 = -6
an = (an-1) * (1/4)
With the above we can assume that:
r = 1/4
following the rule of the explicit formula that is given by:
an = a1 * (r) ^ (n-1)
we substitute and we have:
an = -6 * (1/4) ^ (n-1)
Therefore the explicit formula from the given data would be:
an = -6 * (1/4) ^ (n-1)
