Step-by-step explanation:
Answer:
$5
Step-by-step explanation:
Let the cost of one burger be $b while the cost of one small fries be s
2 burgers and 2 small fries cost $14
This means that;
2b + 2s = 14
divide both sides by 2
b + s = 7 •••••••• (i)
Three burgers and four small fries cost $23
Mathematically;
3b + 4s = 23 •••••••• (ii)
From i , we can see that s = 7- b
we can now substitute this into equation ii
3b + 4(7-b) = 23
3b + 28 -4b = 23
4b -3b = 28 -23
b = $5
one burger costs $5
Answer: No
Step-by-step explanation:
Considering significant: p <= 0.05
A multiple choice question has 18 possible answers, only one of which is correct.
which means that the probability is 1 out 18, so
p = 1/18 = 0.056
As 0.056 > 0.050
Then, it is not significant
