Answer:(E). 25:2
Step-by-step explanation:
First ratio:
Us : India is 5 : 2
Second ratio
India : British is 5 : 1
multiply(5:2) by 5 and multiply (5:1) by 2 to balance the India stamps.
Therefore now
Us : India is 25 : 10
India : British is 10 : 2
The ratio of us : British is 25:2

Answer:
If we examine a sample of tires used for 60,000 miles and determine the proportion that are worn out, how likely is that proportion to be 3.6% or less?
Step-by-step explanation:
First of all, when you want to contrast two hypothesis you need a confidence level p% without which the comparison makes no sense.
In this case, you want to refuse the null hypothesis (the average is 5%) with an alternative one (the average is less than 5%).
You propose a new average (3.6%) based on the evidence.
You cannot prove that the average is actually 3.6%, <em>but if you somehow determine that the probability the average is greater than 3.6% is lower than 100% minus your confidence level p% ,then you can refute the null hypothesis and accept the alternative one as new average.
</em>
So, from the possible choices, the one that fits the best is

Let the volume, as a function of time t, be v:
v(t) = 5 + 2t
v(t) = 5 + 2t
The mathematical model is v(t) = 5 + 2t
