Answer:
2
Step-by-step explanation:
do 9 plus negative 5 then divide by 2 to get your answer
16. LCD: 48 because 1/4= 12/48, 1/12=4/48, 11/16= 33/48 and they all share 48 as the denominator
17. LCD: 168 because 5/56= 15/168, 7/24= 49/168, 7/12= 98/168, 5/42= 20/168
18. LCD: 30 because 2/1= 60/30, 1/5= 6/30, 1/10= 3/30, 5/6= 25/30
Answer:
Step-by-step explanation:
There are 200 dice out of which 199 are fair
Prob for 6 in one special die = 1 and
Prob for 6 in other die = 1/6
A1- drawing special die and A2 = drawing any other die
A1 and A2 are mutually exclusive and exhaustive
P(A1) = 1/200 and P(A2) = 199/200
B = getting 6
i) Required probability
= P(A1/B) = 
P(A1B) = 
P(A2B) = 
P(B) = 
P(A1/B) = 
P(A2/B) = 
-3x = 4y is the answer
Because:
-3 (-4) = 4 (-3)
-7 = -12
Answer:
x = -3 and x = 1
Step-by-step explanation:
first, square each side
12 - 8x = x² - 6x + 9
x² + 2x - 3 = 0
(x - 1)(x + 3) = 0
x = -3
x = 1
