Answer:
Q4 = 4 || Q5 = 6 2/3 || Q6 = 4 4/7 || Q7 = 10 || Q8 = 3 1/3 || Q9 = 4 1/2
Step-by-step explanation:
In order to divide fractions, you just have to turn it into multiplying!
Flip the second fraction in the number sentence and then multiply!
Example: 5 divided by 6/7
Keep 5 as it is. Flip 6/7 to 7/6. 5 x 7/6 = 35/6
Now, simplify it! Simplifying is very simple. You just have to divide until they can't be divided anymore.
35/6 simplified = 5 5/6.
Reason:
How many 6's are in 35? 5 R: 5
So, then it would be 5 5/6.
Hope this helped and this was correct! If you have any more questions, I'll be here to answer them!
Answer:
t Subscript alpha divided by 2 = 2.921
Step-by-step explanation:
With sample sizes lower than 30, we use the t-test.
Otherwise, we use the z-test.
Here, n = 17
So we use the t-test.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 17 - 1 = 16
Now, we have to find a value of T, which is found looking at the t table, with 16 degrees of freedom(y-axis) and a confidence level of 0.99(
). So we have T = 2.921
So the correct answer is:
t Subscript alpha divided by 2 = 2.921
Answer:0.9991
Step-by-step explanation:
The Poisson distribution probability formula is given by :-
, where \lambda is the mean of the distribution and x is the number of success
Given :
