What is Confidence Interval?Confidence interval in statistics is defined as the certain range of values that you estimate for the unknown parameter lies within.
Confidence interval for the population proportion can be calculated as,
p ± z × [tex]\sqrt{\frac{p(1-p)}{n} }[/tex]
Here, p is the sample proportion and n is the sample size.
z value for 95% confidence interval is 1.96.
Here, n = 100,
p = [tex]\frac{62}{100}[/tex] = 0.62
Substituting the values, confidence interval of true proportion is,
0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex]
Hence the 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is 0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex].

What would the answer be?
Answer:
C
Step-by-step explanation:
since ∠ m ≅ ∠ p , then
9x - 2 = 4x + 18 ( subtract 4x from both sides )
5x - 2 = 18 ( add 2 to both sides )
5x = 20 ( divide both sides by 5 )
x = 4
then
∠ p = 4x + 8 = 4(4) + 18 = 16 + 18 = 34°

Answer: 2
Step-by-step explanation:
DE * CE = AE * BE (Two Secants Segment Theorem)
▪︎ DE = 1 + x + 4
▪︎ CE = x + 4
▪︎ AE = 11 + x + 1
▪︎ BE = x + 1
=> (1 + x + 4)(x + 4) = (11 + x + 1)(x + 1)
=> (x + 5)(x+4) = (x + 12)(x + 1)
=> x^2 + 9x + 20 = x^2 + 13x + 12
=> 9x + 20 = 13x + 12

Answer:
x = -9 and 16
Step-by-step explanation:
1. Separate in two cases:
(a) -2x + 7 = 25 and (b) -2x + 7 = -25
(a) -2x + 7 = 25 ⇒ subtract 7 from both sides
-2x = 18 ⇒ divide both sides by -2
x = -9
(b) -2x + 7 = -25 ⇒ subtract 7 to both sides
-2x = -32 ⇒ divide both sides by -2
x = 16
Solutions: x = -9, 16

second line: -9, 6
explanation: split into 4 sections per each 12 so 12/4 is 3 and the location of the first unknown point is one section away from 12 so we know the distance between there is 3, leaving -12+3 = -9. Then two sections less than 12 is 12-6 = 6
third line: -12, 4

A sugar solution currently measures 250 degrees fahrenheit. the temperature of the solution increases 5 degrees per minute. the sugar solution will caramelize at temperatures greater than 310 and less than 338 degrees fahrenheit. which inequality can be used to find x, the number of minutes it will take for the solution to begin caramelizing?
The inequality which is used to find the number of minutes taken by the solution to begin caramelising is 310 < 250 + 5x <338. The correct answer is option A.
The complete question is given below:-
A sugar solution currently measures 250 degrees Fahrenheit. The temperature of the solution increases 5 degrees per minute. The sugar solution will caramelize at temperatures greater than 310 and less than 338 degrees Fahrenheit. Which inequality can be used to find x, the number of minutes it will take for the solution to begin caramelizing? 310 < 250 + 5x < 338 310 < 250 + 5x < 338 310 < 5(x + 250) < 338 310 < 5(x + 250) < 338
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called an inequality.
According to the given question.
The current temperature of a sugar solution is 250 degrees Fahrenheit. Per minute the temperature of the solution increases by 5 degrees. Also, x is the number of minutes taken by the sugar to caramelize.
⇒ The total increase in the temperature in x minutes = 25 + 5x
Since the sugar solution caramelizes at a temperature greater than 310 and less than 338.
Inequality will be given as:-
310 < 250 + 5x < 338
Therefore, the inequality which is used to find the number of minutes taken by the solution to begin to caramelize is given by 310 < 250 + 5x < 338.
