Given:
Cost price of refrigerator = $11515
Discount rate 16% on its marked price.
Profit = 20%
To find:
The marked price of the refrigerator.
Solution:
The cost price (C.P.) is $11515 and the profit percent is 20%. So, the selling price is:
[tex]S.P.=C.P.+20\%\text{ of }C.P.[/tex]
[tex]S.P.=11515+\dfrac{20}{100}(11515)[/tex]
[tex]S.P.=11515+2303[/tex]
[tex]S.P.=13818[/tex]
Let x be the marked price of the refrigerator. Then,
[tex]S.P.=x-16\%\text{ of }x[/tex]
[tex]13818=x-\dfrac{16}{100}x[/tex]
[tex]13818=x-0.16x[/tex]
[tex]13818=0.84x[/tex]
Divide both sides by 0.84.
[tex]\dfrac{13818}{0.84}=x[/tex]
[tex]16450=x[/tex]
Therefore, the marked price of the refrigerator is $16450.

THE FUNCTION! f(x) = x^2+4 is defined over the interval (-2,2). If the interval is dived into n equal parts what is the height of the right endpoint of the kth rectangle?
f(x) = x^2+4 is defined over the interval (-2,2). If the interval is dived into n equal parts the height of the right endpoint of the kth rectangle is mathematically given as
H endpoint = -2+k x5/n. Option A is correct
what is the height of the right endpoint of the kth rectangle?
Generally, the equation for the function is mathematically given as
f(x) = x^2+4
interval is divided = 5/n
endpoint =k x 5/n
therefore,
H endpoint = -2+k x5/n
In conclusion, the height of the right endpoint of the kth rectangle is
H endpoint = -2+k x5/n

2. [5pts] The Pew Research Group conducted a poll in which they asked, "Are you in favor of, or opposed to, executing persons as a general policy when the crime committed while under the age of 18?" Of the 580 Catholics surveyed, 180 indicated they favored capital punishment; of the 600 seculars surveyed, 238 favored capital punishment. Is there a significant difference in the proportion of individuals in these groups in favor of capital punishment for persons under the age of 18? Use the ???? = 0.01 level of significance. Show all work.
Answer:
See below for answers and explanations
Step-by-step explanation:
Here, we are comparing two proportions of a large sample size. Therefore, conducting a 2-proportion z-test is appropriate. Conditions are already assumed, so we can conduct the test.
We are testing our null and alternate hypotheses which are:
H: p1=p2 (there is no difference)
Ha: p1≠p2 (there is a difference)
Given:
x1=180
n1=580
x2=238
n2=600
p1=180/580=0.31
p2=238/600=0.4
p=(180+238)/(580+600)=418/1180=0.35
Use the formula to calculate the z-statistic:
[tex]Z=\frac{p_1-p_2}{\sqrt{p(1-p)(\frac{1}{n_1}+\frac{1}{n_2})}}[/tex]
[tex]Z=\frac{0.31-0.4}{\sqrt{0.35(1-0.35)(\frac{1}{580}+\frac{1}{600})}}[/tex]
[tex]Z=-3.24[/tex]
Calculate p-value (note that this is two-sided):
1) normalcdf(-1e99,-3.24)=5.977105194*10^-4
2) Since this is a two-sided test, we double it to get p=0.001195421
Conclusion: Since 0.0012<0.05, we reject the null hypothesis and conclude that there is a significant difference in the proportion of individuals in these groups in favor of capital punishment for persons under the age of 18 because our p-value is extremely low.

his rounds if he meets each client once?
Answer:24
Step-by-step explanation: 4x3x2x1
The product of a whole number 'n' with every whole number until 1 is called the factorial. The number of ways the lawyer can meet the client is 24 or 4!.
What is a factorial?The product of a whole number 'n' with every whole number until 1 is called the factorial. The factorial of 4 is, for example, 43221, which equals 24.
A lawyer has 4 clients to meet. The number of ways the lawyer can meet the client is 4!.
Number of ways = 4! = 4×3×2×1 = 24
Hence, the number of ways the lawyer can meet the client is 24 or 4!.

Answer:
Step-by-step explanation:
Slope intercept form: y =mx + c
1) x + 4y = 8
4y = -x + 8
Divide the equation by 4
[tex]\frac{4y}{4}=\frac{-x}{4}+\frac{8}{4}\\\\y = \frac{-1}{4}x + 2[/tex]
Here, m = -1/4 and y-intercept = 2
2) 3x + 4y = 0
4y = -3x
Divide the equation by 4
y = [tex]\frac{-3}{4}x[/tex]

BaşarılarThrough extensive data collection, quality control experts have verified that the true mean weight of a wrapped Starburst candy is 5.1 grams, as advertised on the package. However, in a class activity where you selected and weighed 8 wrapped Starburst candies you obtained a p-value of 0.003 and concluded that the true mean weight of Starburst candies is not as advertised. What type of error was potentially made in this hypothesis test
Answer:
Type 1 error.
Step-by-step explanation:
H0 : μ = 5.1
H1 : μ ≠ 5.1
The Pvalue of the test = 0.003
Decision made by the researcher was conclude that mean weight is not as advertised, that is the researcher rejected the Null hypothesis.
However, when the Pvalue is < α - value , we reject the null ; The type of error the researcher could have made is that ; The mean weight may be truly as advertised, Hence, leading us to make a false positive error, thus is rejecting a true null. This is a TYPE 1 error.

In the diagram, KLMN is a rectangle, and the two shaded regions are squares. If the length of KL is 6 centimeters, and the length of KN is 14 centimeters, which is closest to the length of ST in centimeters?
Answer:
15.2cm
Step-by-step explanation:
From the given diagram;
KN = SN = 14cm
KL = NT = 6cm
Required
ST
Using the Pythagoras theorem;
ST² = SN² + NT²
ST² = 14² + 6²
ST² = 196 + 36
ST² = 232
ST = √232
ST = 15.2cm
Hence the length of ST is 15.2cm

The shed that Vicky and Jim will use is the second shed (length | 4 [] width | 2 1/4), because the height length is 7.
4 x 2.25 = 9
63 divided by 9 = 7
(First Shed) 5 x 2.20 = 11
66 divided by 11 = 6
7 > 6
7 = Height of First Shed
The first shed will be used to store the new lawnmower since it is the taller shed.
