-2/3a + 5/6a - 1/6

         

-2/3a + 5/6a = 1/6

1/6 - 1/6 = 0

Answer 2
Answer: -1/6a(-a+1)

you can factor out 1/6 from the equation to make -1/6a (4a-5a+1)
then combine like terms 4a-5a is -a

A group of Physicians must build an addition to their existing private clinic. They are considering three different sized additions; a small addition, a medium addition and a large addition. If the medical demand is high (there is a favorable market for the addition) they would realize a net profit of $100,000 with a large addition, a net profit of $40,000 with a medium addition and a net profit of $10,000 with a small addition. If the medical demand is low (there is an unfavorable market for the addition) they would realize a net loss of $40,000 with the large addition, a net loss of $10,000 with the medium addition and a net profit of $5,000 with the small addition. The Physicians were also able to assign the following utility preference values to each of the potential payoffs they could encounter. Utility of $100,000 is 1.0, U ($40,000) is 0.9, U ($10,000) is 0.6, U ($5,000) is 0.5, U ($-10,000) is 0.4, and U ($-40,000) is 0.0. The physicians also have a reliable forecast indicating a 40% probability of the high medical demand. Using expected monetary value theory, what should they do and what is the expected value of that decision? Using expected utility theory, what should they do and what is the expected utility of that decision?

The bears football team lost 7 yards and then gained 12 yards. what is the result of the two plays

Answers

Answer:

The result of the two plays is that the bears gained 5 yards.

Step-by-step explanation:

We can denote the lost values as negative and won value as positive.

Given is - the bears football team lost 7 yards and then gained 12 yards.

If we take the initial start point to be zero, we can calculate the resultant.

0-7+12=+5

Or we can calculate simply :

-7+12=+5

Hence, the result of the two plays is that the bears gained 5 yards.

Start at 0 and go back 7 yards for their loss.  You are not at -7 on the number line.
Move 12 to the right because of the gain.   It takes 7 or those 12 just to get back to zero and you can still move 5 more to the right.   You will wind up with a gain of 5 yards.  (+5)

Step-by-step explanation:

Answer: 60

Step-by-step explanation:

write down the 12 times table

12 , 24, 36, 48, 60, 72, 84, 96, 108, 120

20, 40, 60, 80, 100, 120, 140, 160, 180, 200

Now you can see that 60 is the multiple that comes up first in both of the times tables which means it is the lowest common factor.

Step-by-step explanation:

The gravitational force exerted on a baseball is 2.24 N down. A pitcher throws the ball horizontally with velocity 17.0 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 183 ms. The ball starts from rest. Through what distance does it move before its release? What are the magnitude and direction of the force the pitcher exerts on the ball?

Answers

To have a weight of 2.21N., the ball's mass is (2.21/9.8) = .226kg. 
a) d = 1/2 (vt), = 1/2 (18 x .17), = 1.53m. 
b) Acceleration of the ball = (v/t), = 18/.17, = 105.88m/sec^2. 
f = (ma), = .226 x 105.88, = 23.92N.
