Given problem is 
To simplify that we need to multiply and divide by conjugate of the denominator
conjugate of denominator 6+i will be 6-i as we just need to change sign of the imaginary part
Now multiply and divide by 6-i







Hence final answer is 
All you have to do is make and simplify a fraction. In this case, there are 6 friends going into 4 pears, so the fraction is 6/4. Then we can simplify that because they are both divisible by 2. So if we divide both by 2, our fraction becomes 3/2. Then we make that into a mixed number, with 3 going into 2 once with 1 left over. That means the answer is 1 1/2.
Solution :
This is the two tailed test.
The null hypothesis and the alternate hypothesis is as :
Null hypothesis is 
Alternate hypothesis is 

Therefore, the critical value of z is :

Now the test statics is :



The test statics is 0.878
We see that it is a right tailed test.


= 0.3800
Thus , P-value > α
So we fail to reject the null hypothesis.

Answer: 15c
Step-by-step explanation:
When you come across any question that mentions [the product of a and b] means a × b
- the product of 6 and 7 is 42, 6 × 7=42
- the product of x and y is xy, x × y=xy
<u>Solve:</u>
The product of 15 and c
<h2>15 × c=15c</h2>
