10% of £36 = £3.60
So you do £36+£3.60
Then your answer is...
B. £39.60
4x + y = 54
8x + 2y = 104
8x + 8y - (8x + 2y) = 240 - 104
6y = 136
y=22 2/3
4x+ 22 2/3 = 54
4x= 31 1/3
x= 7 5/6
P(

![[P(Success)^{r}]](https://tex.z-dn.net/?f=%20%5BP%28Success%29%5E%7Br%7D%5D%20)
×
![[P(failure)]^{n-r}](https://tex.z-dn.net/?f=%20%5BP%28failure%29%5D%5E%7Bn-r%7D%20)
We have




Substitute these values into the formula, we have
P( 2 success in 8 trials) = ⁸C₂ × (0.15)² × (0.85)⁶
P( 2 success in 8 trials) = 0.2376.... ≈ 0.24 = 24%
Answer:
The answer to your question is: x = 10; 1 = 142°
Step-by-step explanation:
Find x and m∡ 1
We know that 6x - 22 = 3x + 8 Because they are vertical angles
6x - 3x = 22 + 8 Solve for x
3x = 30
x = 10
Then ∡ = 6(10) - 22
= 60 - 22
= 38°
1 = [360 - 2(38) ] / 2
= [360 - 76] / 2
= 284/2
= 142°
