Step-by-step explanation:
Answer:
7g+3t+x
Step-by-step explanation:
You really don't have to do anything to this equation because each number in this equation has a variable, but since 1x is just x you can remove the 1 and you new equation becomes:
7g+3t+x
You can look at those dots, for example, you see (2,8) and (2,2) then look at y and the difference is 6. so if you see it like that, (2,8) and (5,8) is 3, (5,8) and (5,4) would be 4, (5,4) and (8,4) would be 3, (8,4) and (8,2) would be 2, and lastly (2,2) and (8,2) is 6
Now you add all of them up which will be 6+3+4+3+2+6 = 24
so the perimeter of this figure is 24<span />

Answer:
He will need 4 newborns in the sample to be 95% confident.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the length of the sample.
So:
He will need 4 newborns in the sample to be 95% confident.
