Hey there! Hello!
So, for this problem, I don't really see an answer choice that fits along with this description?? The last one is the closest to the answer I believe it is, but still doesn't fit exactly:
Twice a number = 2n
Three more than = +3
Final equation = 2n+3
Perhaps you have a typo either in your question or your answer problem, or I'm just way too tired. Either way, I hope this helped you out, and feel free to ask me any additional questions you may have.

Answer:
a) 0.172
b) 0.167
c) 0.1404
Step-by-step explanation:
Margin of error, E = 
here,
p = probability of the event
n = sample size
a) n = 30
p = 10 ÷ 30 = 0.333
Therefore,
E = 
= 2 × 0.0861
= 0.172
b) n = 30
p = 21 ÷ 30 = 0.7
Therefore,
E = 
= 2 × 0.0836
= 0.167
c) n = 30
p = 22 ÷ 50 = 0.44
Therefore,
E = 
= 2 × 0.0702
= 0.1404
Answer:
see explanation
Step-by-step explanation:
To find the intercepts, that is where the graph crosses the x and y axes.
• Let x = 0, in the equation for y-intercept
• Let y = 0, in the equation for x-intercept
x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept
y = 0 : 8x + 0 = - 9 ⇒ x = -
⇒ ( -
, 0) ← x- intercept
