A study of college business majors included 150 sophomores and 200 juniors. The study showed that 80 sophomores and 150 juniors

vlabodo [156]

Answer:

0.3478

Step-by-step explanation:

Given:-

- The number of sophomore, S = 150

- The sophomore and had summer internship, x = 80

- The number of juniors, J = 200

- The junior and had summer internship, y = 150

Find:-

What is the probability that the person is a sophomore given that the person had a summer internship?

Solution:-

- The total sum of sophomore and junior students is N:

N = S + J

N = 150 + 200

N = 350 students.

- We will denote event A as random selection of sophomore from total.

- We will denote event B as random selection of student who had summer internship.

- We are to determine the conditional probability that a person selected is sophomore given that the person had a summer internship. That is the probability of event A given that event B has already occured.

- The conditional probability can be written as:

P ( A / B ) = P ( A & B ) / P ( B )

Where,

P ( A & B ) : The probability the person is a sophomore and had a summer internship.

P ( B ): The probability that the person selected had a summer internship.

P ( A & B ) = x / N

= 80 / 350

= 0.22857143

P ( B ) = ( x + y ) / N

= ( 80 + 150 ) / 350 = 230/350

= 0.65714286

Therefore the required probability is:

P ( A / B ) = 0.22857143 / 0.65714286

= 0.3478 ... Answer

a colleague needs to move a 500 pound object that's on a lever. the fulcrum is 6 inches from the object. If your colleague weigh

Dafna11 [192]

Answer:

Step-by-step explanation:

The easier way to figure this is by using the concept of torque in physics. If the torque of the man is greater than that experienced by the box, the lever will tilt in the man's favor (in other words, he will move down and the box will be lifted). Torque is found by multiplying the perpendicular force by the length of the lever arm. Because we want the man's torque to be greater than the box's torque, the inequality is:

$\tau_{man}>\tau_{box}$ and

$180r>500(.1524)$ That decimal is 6 inches in terms of meters.

180r > 76.2 so

r > .42 meters or `16.67 inches. The man has to sit at a distance greater than 16.67 inches in order for the box to be lifted by the lever.

Consider the graph of the linear function h(x) = –6 + x. Which quadrant will the graph not go through and why?

Lesechka [4]

H ( x ) = - 6 + x
m = 1 ( the slope )
b = - 6 ( y - intercept )
x - intercept:
0 = - 6 + x
x = 6
The graph is going through Quadrants: I, II and IV.
Answer:
B ) Quadrant II, because the slope is positive and y-intercept is negative.
