Answer:
Step-by-step explanation:
Given that a research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=1096 and x=542 who said yes.
i.e. sample size = 
who said yes =
Sample proportion = 
Std error of proportion = 
Margin of error 95% 
Hence confidence interval for proportions
=
a) Point estimate 
B) Margin of error = 
C) Conf interval = 
D) We are 95% confident that for large random samples representing the population, the proportion of yes will lie between these two values.
Answer: The median value of data set B is -5.5, which is less than the median value of 3.1 in dataset A.
Step-by-step explanation:
Order the dataset from least to greatest:
-38 → -13 → -9 → -2 → 14 → 28
Then find the values that lies in the middle:
-38 → -13 → <u>-9 → -2</u> → 14 → 28
Since there are 2 values, find the average of those 2 values:
The median value = -5.5.
The median value of data set B is -5.5, which is less than the median value of 3.1 in dataset A.
Answer:
the radius of the base of the cylinder is 5 cubic inches
Step-by-step explanation:
Answer:
B. 96 units
Step-by-step explanation:
DA is 6 units and HE is 36 units. There are the same side, but HE is 6 times larger.
AB is 16 units, but since all the sides on the left shape are 6 times larger, EF has to be 16*6, which is 96 units.
Hope this helps
Answer:
JL = 16x-2
Step-by-step explanation:
From the diagram, we can see that;
JL = JK + KL
Thus;
JL = 9x-5 + 7x + 3
JL = 9x + 7x -5 + 3
JL = 16x -2
