Answer:
C
Step-by-step explanation:
the variables in this system of equations are b and p these represent distance walked.
4b + 5p = 2 represents the total amount of time the walk takes
b + p = 8 represents the total distance walked :)
The answer isn't A only because the word problem states that from her house to the beach, it should be represented as b. And p for the beach to the park.
Answer:
The margin of error for constructing a 95% confidence interval on the population mean income before taxes of all consumer units in the U.S is 1406.32.
Step-by-step explanation:
We are given that according to a survey of 500, the mean income before taxes of consumer units (i.e., households) in the U.S. was $60,533 with a standard error of 717.51.
Margin of error tells us that how much our sample mean value deviates from the true population value.
<u></u>
<u>Margin of error is calculated using the following formula;</u>
Margin of error =
where,
= level of significance = 1 - confidence level
= 1 - 0.95 = 0.05 or 5%
Standard of Error =
= 717.51
Now, the value of z at 2.5% level of significance (
) is given in the z table as 1.96, that means;
Margin of error =
=
= 1406.32
Hence, the margin of error for constructing a 95% confidence interval on the population mean income before taxes of all consumer units in the U.S is 1406.32.

Answer:
6 = 6/1 = 12/2 = 18/3
Step-by-step explanation:
The simplest ratio of integers with a value of 6 is ...
6 = 6/1
We can multiply numerator and denominator by any non-zero integer value to obtain an equivalent:
6 = 12/2 = 18/3 = -54/-9
Inequality hope this helps :)
