3 ways. You can do 1 from the 26 class. 2 from the 31 and 1 from the 28 class
2 from the 26 class, 1 from the 31 class and 1 from the 28 class
2 from the 28 class, 1 from the 31 class and 1 from the 26 class
There is 12 months in a year so you need to multiply 12 by 110 which is 1320
Your answer is: 1320 saved in one year
Hope this helped :)
The third one
3(x+5) = 3 * x + 3 * 5
Answer: 601
Step-by-step explanation:
When the prior estimate of the population proportion is unavailable , then the formula to find the sample size is given by :-
![n= 0.25(\dfrac{z^*}{E})^2](https://tex.z-dn.net/?f=n%3D%200.25%28%5Cdfrac%7Bz%5E%2A%7D%7BE%7D%29%5E2)
, where E = margin of error
and z* = Critical z-value associated with the confidence level.
As per given , we have
The prior percentage of full-time college students who earn a bachelor's degree in four years or less is not given.
E= 0.04
We know that the critical value for 95% confidence level = z*= 1.960
Then , the required sample size is given by :-
![n= 0.25(\dfrac{1.960}{0.04})^2](https://tex.z-dn.net/?f=n%3D%200.25%28%5Cdfrac%7B1.960%7D%7B0.04%7D%29%5E2)
![n= 0.25(49)^2](https://tex.z-dn.net/?f=n%3D%200.25%2849%29%5E2)
Hence, the required sample size is 601.
Answer: First, Third and Fourth options are correct.
Step-by-step explanation:
As we know that Rational numbers are those numbers which can be positive integers, negative integers and can be written in the form of p/q i.e. in fractions.
So, it is true for positive integers
It is true for negative integers.
It is true for fractions.
Hence, First, Third and Fourth options are correct.
