Answer:
B) 8
Step-by-step explanation:
Triangles MNC and RSC are similar because all 3 angles are the same, so the the ratio between each side should be the same.
If NC=12 and SC=6 then triangle MNC is scaled up by 2 from triangle RSC. This means each side of MNC is 2 times bigger than on RSC. So, sense RS=4, we can multiply that by 2 to get MN=8.

Hypothesis testing
For this problem, we need to use the t-student distribution to make inference about the data. We calculate the t-statistics as below:
Using a t-statistics table, or using the function TDIST in Microsoft Excel with 
with two-tailed distribution, we obtain .

Answer:
0.7070707070 is not an irrational number
Step-by-step explanation:
Irrational numbers cannot be expressed as a ration. These numbers are non repeating and non terminating. For example π is an irrational number.
In the given number 0.7070707070, we can see that 70 is repeating and it terminates as well.
Therefore, from the above definition of irrational numbers we can conclude that the number 0.7070707070 is not an irrational number because it terminates as well as repeated.
