Answer: 2 : 1
Step-by-step explanation:
The batter calls for 2 cups of flour and 1 cup of milk.
That means that for every 2 cups of flour, the muffin batter would need 1 cup of milk.
Ratio of flour to milk will therefore be:
= Amount of flour needed : Amount of milk needed
= 2 cups of flour : 1 cup of milk
= 2 : 1

Using a random sample of 4100 households, a media research company finds that 55.1% watched a particular episode of a popular situation comedy. a. Find the margin of error in this percent. b. Write a statement about the percentage of TV households in the population who watched the episode of the situation comedy.
Answer:
a. 1.52%
b. There is 95% probability that the true population percentage lies between 53.8$ and 56.62%
Step-by-step explanation:
The number of participants in the sample, n = 4,100
The percentage that watched the particular popular situation episode, p = 55.1%
a. The margin of error is given by the following formula;
[tex]Margin \ of \ Error = Z_{\alpha /2} \times \sqrt{\dfrac{p \times (1 - p)}{n} }[/tex]
Where;
Z = The z-score at 95% = 1.96
p = The proportion of the sample that responded positively = 55.1% = 0.551
n = 4,100
From the above data, we get;
[tex]Margin \ of \ Error = 1.96 \times \sqrt{\dfrac{0.551 \times (1 - 0.551)}{4,100} } \approx 0.0152252[/tex]
The margin of Error ≈ 1.52%
b. The confidence interval is give as follows;
[tex]p \pm Z_{\alpha /2} \times \sqrt{\dfrac{p \times (1 - p)}{n} }[/tex]
Therefore, we get the 95% confidence interval as follows'
55.1 - 1.52 ≤ μ ≤ 55.1 + 1.52
53.8% ≤ μ ≤ 56.62%
The answer as formatted in an online source is presented as follows;
There is 95% probability that the true population percentage lies between 53.8$ and 56.62%.

What is the measure of angle 4?
angles 1,3,5,6,7, and 8 are 73 degrees. angles 2 is 107 degrees
Answer:
34 Deg
Step-by-step explanation:
Since the Triangle is isoceles, each of the internal base angle = 180-107=73
Sum of internal angles =180, Angle4= 180-(73+73)= 180-146=34

Answer:
the answer is c
Step-by-step explanation:
no soloutions have the same slope but different intercepts so it cannot be d because the slopes are different.
What is the value of this expression when c=-4 and d = 10?
1/4(c3+d2)
What is the value of this expression when c = -4 and d = 10 ? [tex] \frac{1}{4} [/tex] (c³ + d²)
Answer:-Given:-[tex] \frac{1}{4} [/tex] (c³ + d²) where c = -4 and d = 10
To Find:-The value of the expression [tex] \frac{1}{4} [/tex] (c³ + d²)
Solution:-[tex] \frac{1}{4} [/tex] (c³ + d²) [Given expression]
Now, putting the value of c = -4 and d = 10 , we get,
[tex] \frac{1}{4} [/tex] { (-4)³ + (10)² }
[tex] \frac{1}{4} [/tex] ( -64 + 100 )
[tex] \frac{1}{4} [/tex] ( 36 )

An electronics store buys 200 stylus at a cost of $400 and sells them for $6 each. Find the percent markup rounded to the nearest percent?
Answer:
Percent markup is 200%
Step-by-step explanation:
The cost of each stylus is
[tex]\frac{400}{200} = 2[/tex] dollars
The selling price of each stylus is $6
Percent markup =
(Selling price - cost price)/cost price *100
[tex]\frac{6-2}{2} *100\\2*100\\200[/tex]%
Percent markup is 200%

if the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.
A. 13.17
B. 12.25
C. 11.32
D. 10.42
Answer:
m = rise/run = 270/20.5 = 13.17
Step-by-step explanation:
Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270. Thus, the slope is
m = rise/run = 270/20.5 = 13.17
length=2
width=2

Answer:
12
Step-by-step explanation:
The computation of the volume of the rectangular prism is shown below:
As we know that
The volume of the rectangular prism is
= length × width × height
where
Length is 2
width be 2
And, the height be 3
So, the volume of the rectangular prism is
= 2 × 2 × 3
= 12
