start fraction, 9, divided by, 25, end fraction of Polly's co-workers prefers tea over coffee.
What percent of Polly's co-workers prefer tea over coffee?
Answer: To convert a fraction to a percentage you multiply by 100.
(9 / 25) * 100
= 9 * 100/25
= 9 * 4
= 36% answer
Step-by-step explanation:
A polling company is trying to estimate the percentage of adults that consider themselves happy. A confidence interval based on a sample size of 360 has a larger than desired margin of error. The company wants to conduct another poll and obtain another confidence interval of the same level but reduce the error to one-third the size of the original sample. How many adults should they now interview
Reducing the sample size to one-third, increases the error by √3.
Margin of ErrorThe margin of error is given by:
[tex]E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{n} } \\\\where\ z_\frac{\alpha}{2} \ is \ the \ confidence\ level\ z\ score, \sigma\ is \ mean\ and\ n\ is\ sample\ size.\\\\n=360, hence:\\\\E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{360} } \\\\E=0.0527(z_\frac{\alpha}{2} *\sigma)\\\\For\ n = 1/3 * 360=120:\\\\\\E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{120} } \\\\E=0.09122(z_\frac{\alpha}{2} *\sigma)[/tex]
Reducing the sample size to one-third, increases the error by √3.

Answer:
[tex]x=3c\sqrt{a} -b^2[/tex]
Step-by-step explanation:
[tex]\sqrt{a} =\dfrac{x+b^2}{3c}[/tex]
Multiply both sides by 3c:
[tex]\implies \sqrt{a} \cdot 3c=\dfrac{(x+b^2) \cdot 3c}{3c}[/tex]
[tex]\implies 3c\sqrt{a} =x+b^2[/tex]
Subtract [tex]b^2[/tex] from both sides:
[tex]\implies 3c\sqrt{a} -b^2=x+b^2-b^2[/tex]
[tex]\implies 3c\sqrt{a}-b^2=x[/tex]
Switch sides:
[tex]\implies x=3c\sqrt{a} -b^2[/tex]

HELP ME PLEASE!!! A ball is thrown in the air from a platform that is 112 feet above ground level with an initial vertical velocity of 32 feet per second. The height of the ball, in feet, can be represented by the function shown where t is the time, in seconds, since the ball was thrown.
h(t)=−16t2+32t+112
Which of the following equations shows the function rewritten in the form that would be best used to identify the maximum height of the ball?
Question 16 options:
h(t)=−16(t−2)2+112
h(t)=−16(t−1)2+80
h(t)=−16(t−1)2+96
h(t)=−16(t−1)2+128
The ball thrown upwards follows a parabolic path
The equation that shows the function rewritten in the form that would be best used to identify the maximum height of the ball is [tex]h(t)=-16(t-1)^2+128[/tex]
How to determine the equivalent equationThe equation is given as:
[tex]h(t)=-16t^2+32t+112[/tex]
Factor out -16
[tex]h(t)=-16(t^2-2t)+112[/tex]
Express the bracket as a perfect square expression
[tex]h(t)=-16(t^2-2t + 1 - 1)+112[/tex]
Factor out -4
[tex]h(t)=-16(t^2-2t + 1)+112 + 16 * 1[/tex]
[tex]h(t)=-16(t^2-2t + 1)+128[/tex]
Express as a perfect square
[tex]h(t)=-16(t-1)^2+128[/tex]
Hence, the equivalent expression is [tex]h(t)=-16(t-1)^2+128[/tex]

Frederick asked a bank teller to cash a $390 check using $20 and $50 bills. If the teller gave
him 15 bills, how many of each did he receive?
12 of $20 and 3 of $50 totally didnt edit it... lolol..
Answer:
12 $20 Bills & 3 $50 Bills
Step-by-step explanation:
Because if the total is $390, Then if you get 10 $20 Bill that would equal $200 Bills and if you get 2 $50 Bills then you would get $100. Add the $200 Bills & the $100 Bills you get $300 Bills.
Then you get 1 $50 Bill and 2 $20 Dollar Bills you get $90 Bills.
Add $300 Bills with $90 Bills and you get $390.
If you add the number of bills handed it would be 15.
