Answer:
25/121
Step-by-step explanation:
This is called sampling with replacement.
The probability of getting a red marble in one sample is 5/11. Since you are sampling twice, the probability of picking a red marble both times is 5/11 X 5/11 = 25/121. That is slightly less than ⅕.

210 we can write it as 210 = 180 + 30.
So 210 has a reference angle of 30 degree in third quadrant.
So x co-ordinate of terminal point is cos(210) =

y co-ordinate of terminal point is sin(210) =

So the terminal point is
Answer:
y = 225
Step-by-step explanation:
since y and x are directly proportional the equation relating them is
y = kx ← k is the constant of proportionality
to find k use the given condition y = 288 when x = 32
k =
=
= 9
y = 9x ← is the equation of proportionality
when x = 25, then
y = 9 × 25 = 225
Answer:
x=46/5
Cross multiply, distribute the denominator, simplify by combining like terms, and isolate x.
Answer:
x ≤ 7
Step-by-step explanation:
(2x-4) + 110 ≤ 120
Combine like terms
2x +106 ≤ 120
Subtract 106 from each side
2x+106 -106 ≤ 120-106
2x ≤ 14
Divide each side by 2
2x/2 ≤ 14/2
x ≤ 7
