Find the distance between the two points 4,1 and -3,-2. Show your work
1 answer:
Answer:
The distance between two points is √58 or 7.61.
Step-by-step explanation:
In the question we need to find the distance between two points 4,1 and -3,-2 given.
Distance between two points can be found using the formula:
Putting the given points in the formula we get,
x₂ = -3, x₁ = 4, y₂= -2, y₁= 1
So, the distance between two points is √58 or 7.61.

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.

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
