Answer:
b) True , this is right. But this is not for 1000 alone for any sample size of large number randomly drawn we can expect 95%
Step-by-step explanation:
Given that in 2013, the Pew Research Foundation reported that "45% of U.S. adults report that they live with one or more chronic conditions", and the standard error for this estimate is 1.2%
Let us check one by one answers given
a) False. Because we can say 95% or 90% confident only that the true percent of US adults cannot be true.
b) True , this is right. But this is not for 1000 alone for any sample size of large number randomly drawn we can expect 95%
c) False this does not give whether less than 50% or not unless we know the confidence interval range.
d) False, std error is a measure of variation of all the items from the mean.
Answer:
$8 for Senior Citizens
$12 for Students
Step-by-step explanation:
Let C be the price of a senior citizen ticket
Let S be the price of a student ticket.
We are told that, on the first day, that:
7C + 4S = $104
On the second day:
7C + 1S = $68
We have 2 equations and 2 unknowns. Rearrange either equation to express one of the unknowns in terms of the other
For example:
7C + 1S = $68
S = $68 - 7C
Now use this value of S in the other equation:
7C + 4S = $104
7C + 4($68 - 7C) = $104
7C + $272 - 28C = $104
-21C = - $168
<u>C = $8 for a Senior Citizen ticket</u>
We can use C = $8 in either equation to find S.
S = $68 - 7C
S = $68 - 7($8)
S = $12
<u>Student tickets are $8 each</u>
=====
See if these values work in the original equations:
1. 7C + 4S = $104
7($8) + 4($12) = $104 ?
$56 + $48 = $104 <u>YES</u>
2. 7C + 1S = $68
7($8) + 1($12) = $68 ?
$56 + $12 = $68 <u>YES</u>
Which is more 4/5 or 0.71? Because decimals are usually easier to read, convert the 4/5 to a decimal. To do this, divide the numerator by the denominator. 4 / 5 = 0.8.
0.8 is bigger than 0.71. So, 4/5 is definitely bigger than 0.71.
But what about 1.2 and 1 2/9? Again convert 1 2/9 to a decimal.
2/9 = 1.222...
And 1.222 repeating is bigger than 1.2
