Its C 10d+ 5n I know it doesnt tell you numbers but a dime is 10 cents and a nickel is 5 cents which obviously would help you find the answer but you dont need the answer just how they would make it an problem so yea, its C 10d + 5n
The answer is A.
Hope it helps
Answer:
0
Step-by-step explanation:
The y intercept is the constant in this equation, as in the only number unaccompanied or affected by a variable. In this case, assuming y is a and x is t, the y intercept is 0. You can test this by plugging in y=10x+0 into a graphing calculator. The y intercept is where x equals 0, and so if you plug in 0 for x, the result (in this case 0) is the y intercept. Hope this helps, brainliest is always appreciated and have an amazing day!
Answer:
Yes
Step-by-step explanation:
After solving for the two values of a, the second inequality gives a value inside the range of the first inequality.
Answer:
This means that the first interval, with 9000 viewers, is 3 times as narrower as the second interval, with 1000 viewers.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The width of the interval is:

In this sample:
Two 90% intervals, with different lenghts. So both have the same values for z an 
Interval A:
9000 viewers.
So the width is

Interval B:
100 viewers
So the width is

Relationship between the widths:

This means that the first interval, with 9000 viewers, is 3 times as narrower as the second interval, with 1000 viewers.
