Part A:
Price before tax: $49.99
Discount: 50% of $49.99 = 50% * $49.99 = 0.50 * $49.99 = $25.00
Discounted price: $49.99 - $25.00 = $24.99
Tax on discounted price: 8% of $24.99 = 8% * $24.99 = 0.08 * $24.99 = $2.00
Part B:
Total price: $24.99 + $2.00 = $26.99
Answer:
0.6666 or
Step-by-step explanation:
Since this is a ratio problem we can simply use the rule of three to solve it. We need to multiply the diagonal values and divide by the remaining value to get the variable which in this case is x (how much life he has already lost)
15 minutes <=======> 1 life
10 minutes <=======> x
(10 * 1) / 15 = x
10 / 15 = x
0.6666 or = x
Finally, we can see that Farid has lost 0.6666 or in those 10 minutes
Answer: (0.24 - 1.96*0.019, 0.24 + 1.96*0.019)
Step-by-step explanation:
We know that the confidence interval population proportion (p) is given by :-
, where = sample proportion.
z* = Critical value (Two -tailed)
SE = standard error
Given : In 2012, about 24% of high-school seniors reported binge drinking (defined as five or more drinks in a row in the past two weeks), a substantial drop since the late 1990s.
SE = 0.019
Significance level =
Two-tailed value corresponds for :
z*=1.96 [Using z-table]
Now, the 95% confidence interval for the proportion of high-school seniors in the sample who would report binge drinking will be :-
Hence, the correct answer = (0.24 - 1.96*0.019, 0.24 + 1.96*0.019)
Gavin's number is 68.6
Equation: 1/2(x) = 34.3
Use inverse operations on both sides.
1/2(x) = 1x or x = 34.3(2)
34.3(2) = 68.6
Thus, x equals 68.6
