Godel is asked to perform the addition problem below. Godel believes that because there are more negative numbers, the answer wi
1 answer:
Answer:
Godbel is wrong in the reasoning as the answer does not depend on the number of negative numbers in the expression. Instead it depends on the value of the sum of positive terms and the value of the sum of negative terms. If the values of sum of positive terms is greater than the value of the sum of negative terms then the answer will be a positive and vice versa.
Step-by-step explanation:
Given expression:
To evaluate the expression.
Solution:
We have:
Removing parenthesis first as a positive and negative multiply to give a negative.
⇒
Then we can group the positives and negatives together.
⇒
⇒
Since the negatives combine by getting added up with the sum being negative, so we have:
⇒
As, we can see the positive value (21) is greater than the negative value (15) and hence the answer would be a positive.
⇒ 6

Complete question :
Suppose that of the 300 seniors who graduated from Schwarzchild High School last spring, some have jobs, some are attending college, and some are doing both. The following Venn diagram shows the number of graduates in each category. What is the probability that a randomly selected graduate has a job if he or she is attending college? Give your answer as a decimal precise to two decimal places.
What is the probability that a randomly selected graduate attends college if he or she has a job? Give your answer as a decimal precise to two decimal places.
Answer:
0.56 ; 0.60
Step-by-step explanation:
From The attached Venn diagram :
C = attend college ; J = has a job
P(C) = (35+45)/300 = 80/300 = 8/30
P(J) = (30+45)/300 = 75/300 = 0.25
P(C n J) = 45 /300 = 0.15
1.)
P(J | C) = P(C n J) / P(C)
P(J | C) = 0.15 / (8/30)
P(J | C) = 0.5625 = 0.56
2.)
P(C | J) = P(C n J) / P(J)
P(C | J) = 0.15 / (0.25)
P(C | J) = 0.6 = 0.60
Since the problem is not telling us the height of Silvio, we are going to assume it is not relevant for our calculations.
Let
the altitude of the incoming plane. We know for our problem that the distance between Silvio and the tower is 3 miles, Also we know that the angle of elevation to the plane is 40°. With this information we can create a triangle as shown in the figure. We need a function that relates the angle of elevation with its opposite and adjacent sides, that function is tangent.
We can conclude that we should use the trig function tangent to model this situation; also, we can conclude that the equation that describes this situation is.
