Mr. Starnes wondered what proportion of Katy Perry's Twitter followers are
female, so he selected a random sample of 500 of Katy Perry's followers. In the
sample, 308 are female. Construct and interpret a 90% confidence interval for the
true proportion of Katy Perry followers that are female.
Answer and Step-by-step explanation:
To calculate a confidence interval for a proportion:
1) Determine the proportion
[tex]p=\frac{308}{500}[/tex]
p = 0.616
2) A 90% confidence interval has z-score that is 1.645.
3) Calculate margin of error
[tex]ME=\sqrt{\frac{p(1-p)}{n} }[/tex]
where
n is the sample size
So
[tex]ME=\sqrt{\frac{0.616(1-0.616)}{500} }[/tex]
[tex]ME=\sqrt{\frac{0.616(0.384)}{500} }[/tex]
ME = 0.02175
Then the interval is given by
p ± z(ME)
0.62 ± 1.645(0.02175)
0.62 ± 0.035
The interval will be
0.585 < p < 0.655
What this means is that we are 90% confident that the true proportion of Katy Perry's Twitter female followers is between 0.585 and 0.655.

Solve for x your answer must be simplified. -4+x<9
Answer:
x<13
Step-by-step explanation:
To solve this, we want to have the isolate the variable x on the left side, by itself without a coefficient. All we have to do to do this is add 4 to both sides, cancelling out the -4 and getting x<13
Answer:
x = 13 + y
Step-by-step explanation:
Simplify:
-4 + x = y + 9
Reorder the terms:
-4 + x = 9 + y
Move all terms containing x to the left all other terms to the right
Add 4 to each side of the equation
-4 + 4 + x = 9 + 4 + y
Combine like terms: -4 + 4 = 0
0 + x = 9 + 4 + y
x = 9 + 4 + y
9 + 4 = 13x = 13 + y
Answer:
x = 13 + y

Solve problem using substitution
2x + y = 10
y = x + 1
Answer:
x = 3
y = 4
Step-by-step explanation:
2x + y = 10 -----------------(I)
y = x + 1 ---------------------(II)
Substitute y = x + 1 in equation (I)
2x + x + 1 = 10 {Combine like terms}
3x + 1 = 10 {Subtract 1 from both sides}
3x = 10 -1
3x = 9 {Divide both sides by 3}
x = 9/3
x = 3
Plugin x = 3 in equation (II)
y = 3 + 1
y = 4

Abdullah and Kanna are working on the same problem.
A juice box has 20% more juice in its new packaging.
The original packaging held 12 fluid ounces. How
much juice does the new packaging hold?
Whose double number line is correct?EXPLAIN YOUR THINKING!!!!!!!
Answer:
Abdullah is correct.
Step-by-step explanation:
The bottle contained originally 12 fl oz, so 12 fl oz is 100%.
The box now contains 20% more, so now it contains 120% of 12 fl oz.
120% * 12 fl oz = 1.2 * 12 fl oz = 14.4 fl oz
Also, 20% is 1/5. Abdullah divided 12 oz into 5 equal parts, and then he added one more 1/5. He interpreted the problem correctly. The amount in the new bottle is the amount of the old bottle plus 20% of that old amount.
Kanna considers the original amount to be 80%. When he adds another 20%, he is adding 1/4 of 12 which is too much. That is why he gets an incorrect answer that is to high. He interpreted the problem incorrectly. For him, the old bottle has 20% less than the new bottle. That is incorrect.
Abdullah is correct.

Solve each system using substitution. Check your answer.
x+y=8
y=3x
Answer:
x = 2
y = 6
Step-by-step explanation:
x + y = 8
x + (3x) = 8
4x = 8
4x ÷ 4 = 8 ÷ 4
x = 2
-------------------------------
y = 3x
y = 3(2)
y = 6
----------------------------------
x + y = 8
(2) + (6) = 8
8 = 8
