PLS
Answer:
ok so the bottom of this shape is 4
the sides are 5 and there is two of them
and then if we count if looks like there is 2 going down and two going up so
4+5*2+2*2
4+10+2*2
4+10+4
14+4
18
Hope This Helps!!!
there were 12 cups of cereal in the box, predict about how many raisins should there
be in the box?
Answer:
counted 27 raisins. If
there were 12
Answer:(-1/2^x)(50000)
Step-by-step explanation:
The fraction is closer to 1/2 than to 0 or 1 is 8/12.
The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
Given:
First Fraction
2/12 = 1/6 = 0.1667
Second Fraction
3/12
= 0.25
Third Fraction
8/12
= 0.6667
Fourth Fraction
10/12
= 0.83333
So, Fraction closer to 1/2 or 0.5 is 8/12.

In this situation I would convert the 1/2 into a fraction that has a common denominator. 1/2 will now be 6/12.
I think the best answer here is 8/12 because 6/12 is only two lines away from 8/12 where as everything else is either closer to 1 or 0.
I hope this helps. Good luck.
B) Calculate the sample proportion.
C) Explain the relationship between the population proportion and the sample proportion.
Answer:
Given:
n = 1003
q = 1 - 0.4606 = 0.5394
a) The sample size and count.
Here the sample size is the number that took part in the poll. It is denoted as n = 1003.
The count is the number that answered yes. Count = 462
b) The sample proportion.
The formula for sample proportion is:
Therefore, sample proportion =
c) The relationship between population proportion and sample proportion.
Since the sample size is greater than 30 (n>30), the sample size is large. Hence, for a large sample, the population proportion is approximately equal to the sample proportion.
This means the population proportion, p = 0.4606
Answer:
A) Sample size n=1003
Count x=462
B) Sample proportion p=0.46
C) The population proportion can be estimated with a confidence interval, with the information given by the sample proportion.
The 95% confidence interval for the population proportion is (0.429, 0.491).
Step-by-step explanation:
A) The sample size include all the adult that answer the poll. The sample size is then n=1003.
The count is the number of adults that answer Yes in this case. The count is x=462.
B) The sample proportion can be calculated dividing the count by the sample size:
C) The population proportion is not known. It can only be estimated with the information given by samples of that population. The statistical inference is the tool by which the sample information can be used to estimate the population characteristics.
With the sample proportion p we can estimate a confidence interval for the population proportion.
We can calculate a 95% confidence interval.
The standard error of the proportion is:
The critical z-value for a 95% confidence interval is z=1.96.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 95% confidence interval for the population proportion is (0.429, 0.491).
We have 95% that the population proportion is within this interval
