Answer:
-1 5/9
Step-by-step explanation:
so first, simplify the signs so they don’t confuse you,
-5/6 - 17/18 + 2/9 (Since there are two negatives near the end, and their tecxhnically being mulitplied, -2/9*-1 (I added 1 for place holder) and when you multiply a negatives by a negative, you get a positive.
So find the lcm of the denominators which is 18 in this case
-15/18 - 17/18 + 4/18
Now solve the problem from left to right
you’ll get -1 5/9 if you simplified
Answer:
P(A&B) = 0.4
Explanation:
Because it is a random process and there are no special constraints the probability for everybody is the same, the probability of choosing a particular site is 1/7, the person originally seated in chair number seven has 5/7 chance of not seating in chair number six and seven, the same goes for the person originally seated in chair number six; Because we want the probability of the two events happening, we want the probability of the intersection of the two events, and because the selection of a chair change the probability for the others (Dependents events) the probability P(A&B) = P(A) * P(B/A) where P(A) is 5/7 and the probability of choosing the right chair after the event A is 4/7, therefore, P(A&B) = 4/7*5/7 = 0.4.
If the events were independent the probability would be 0.51.
The formula is
A=p e^rt
A future value?
P present value 2500
E constant
R interest rate 0.05
T time 10 years
A=2,500×e^(0.05×10)
A=4,121.80
Answer:
-2948
Step-by-step explanation:
Two signs (addition and subtraction) together makes subtraction when having a positive sign and a negative sign
Then subtract -38 and 2910
B because 1/4 people own individual stocks. 1/4 of 12 is 3.
