Answer:
2/3
Step-by-step explanation:
since they are just two colors of fish inside, since the probability is always 1.. so we have to minus 1/3 from 1,which is 1-1/3=2/3
Answer:
y = 0.36
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 9 when x = 2 , then
9 = 
= 
( multiply both sides by 4 )
36 = k
y = 
← equation of variation
When x = 10 , then
y = 
= 
= 0.36
The experimental probability of landing on heads is the same as the theoretical probability of landing on heads.
Answer:
Step-by-step explanation:
Gabriela has solved incorrectly. 5 should distributed to 9x & (-8) and 4 should be distributed between x & 2
5(9x - 8) = 4*(x + 2)
5*9x - 5*8 = 4*x + 4*2
45x - 40 = 4x + 8
Subtract 4x from both sides
45x - 4x - 40 = 8
41x - 40 = 8
Add 40 to both sides
41x = 8 + 40
41x = 48
x = 48/41
Answer:
C.
Step-by-step explanation:
Let's solve your equation step-by-step.
