Hello.
Firstly, let's isolate x on the equation:
Now, we can replace 'x' for 'y' and vice-versa:
Hope I helped.
If 500 high school students, 376 said they would prefer to have computers in every classroom then the confidence interval at 95% is (71.41%,78.99%) Since option (a) is correct.
Given x= 376, n = 500
The (71.41%,78.99%)
Critical values
Using the z-table the z-critical value at the given significance level at α=0.05 is,
Construct a 95% confidence interval
That is,
= (71.41%,78.99%)

5 packages of biscuits and 3 of pamphlets.
<span>The real thing to pay attention to is the word *smallest* and the numbers, along with the labels of what they represent. If you can only have who packages of 20, that's a limiting point. Make sure whatever multiple you buy, the biscuits have a value that ends in 0, such as the numbers 20, 30, 40, 50, 60 etc. The first number to multiply 12 by to give you a number like that is to multiply it by 5. That gives you 60. Then multiply 20 by 3 to get sixty. </span>
The highest common factor of 630 and 1560 is 30.
630, 1560 | 10
63, 156 | 3
21, 52
Now you multiply 10 by 3 and you get 30. Thirty is the highest number that you can use to divide these two numbers.
1/17 I think is the answer
