Answer:
{n*(n+1) } /2
Step-by-step explanation:
The clearest pattern is that the last digit is multiplied by the number after it and then the multiplication is divided by 2.
1 is multiplied by 2, then divided by 2.
2 is multiplied by 3, then divided by 2.
3 is multiplied by 4, then divided by 2.
So, the pattern is:
{n*(n+1) }/2.
Hope this helped!
Answer:
a) Repeated measure ANOVA techniques you can use along with the Hypothesis Testing, and your Null Hypothesis will be that there is no effect between the rat pups you have and the new available as claimed by the salesman.
b) In this part you can use ANOVA for measuring the variance produced by all three factors and Null Hypothesis will be that there is no effect of all these factors, if we get the pvalue less than 0.05 then our Alternate hypothesis will be that the factors has some effect.
c) In this type of problem where we have more than 3 Nos of Independent Variable we have to use Linear Regression to check our hypothesis that whether there is significant variance exist between different variables or not.
d) Okay you can use paired sample t-test in this question since you have only two brands to test and comparing the means over the hypothesis will lead you to the best solution.
Thanks Please try to be more elaborating while asking questions like what is chapter and context of the questions.
Thanks
Answer:23%, 0.634, 3/4, 8/10
Answer:
y = -3, x = 5
Step-by-step explanation:
In the first equation, x = 2 - y, x is on one side. So we can try to isolate the variable x in the second equation by adding 2y + 11 on both sides to get:
x = 2y + 11
So now we have equations x = 2 - y and x = 2y + 11. Therefore 2 - y = 2y + 11. Now we isolate variable y by adding y on both sides and subtracting 11 on both sides to get -9 = 3y. Divide by 3 on both sides to get y = -3.
Let's substitute that into x = 2 - y. Since y = -3, we now have x = 2 - (-3) = 5.
