Step-by-step explanation:
A polling agency reported that the proportion of 12th grade students who are engaged is 0.34. Engagement is defined as students' involvement and enthusiasm with school. The superintendent of one high school district believes the engagement of her students is higher than the proportion reported. She randomly surveys 90 of the 3600 students in the district and finds that 38 reported being engaged in school.
Required:
a. What type of variable is "engaged"?
b. What is the sample proportion of students in this high school district who are engaged?
Answer:
a) "engaged" is a quantitative and continuous variable.
b) The sample proportion of students in this high school district who are engaged is 0.4222
Step-by-step explanation:
Given the data in the question;
Polling reports shows that 0.34 12th grade students are engaged
the principal surveyed 90 of the 3600 students,
number of students reported to be engaged is 38
a)
"engaged" is a quantitative and continuous variable.
b) the sample proportion of students in this high school district who are engaged.
Sample proportion of engaged = number of students reported to be engaged / total number of students surveyed
so
Sample proportion of engaged = 38 / 90
Sample proportion of engaged = 0.4222
Therefore, the sample proportion of students in this high school district who are engaged is 0.4222

Suppose we know that a confidence interval is (71,95), with a sample mean of x¯=83.
What is the margin of error?
Give just a number for your answer. For example, if you found that the margin of error was 2, you would enter 2.
Provide your answer below:
Answer:
12
Step-by-step explanation:
Recall :
Confidence interval = xbar ± margin of error
Xbar = 83
Confidence interval = (71, 95)
We could use either the lower or upper boundary to obtain an integer for the margin of error :
Using the upper boundary :
Upper boundary = Xbar + margin of error
95 = 83 + margin of error
Margin of Error = 95 - 83
Margin of Error = 12
What is the length of AP?
1) 10
2) 12
3) 17
4) 24
Answer:
4) 24
Step-by-step explanation:
OA = OB = 7 ( radius )
OP = OB + BP
= 7 + 18
OP = 25
In triangle OPB,
By Pythagoras theorem,
( OP )² = ( OA )² + ( AP )²
( AP )² = ( OP )² - ( OA )²
= 25² - 7²
= 625 - 49
( AP )² = 576
AP = 24
Answer:
your answer will be 24
Step-by-step explanation:
∠OAP=90°
OA=OB=7
[tex]OA^{2} +Ap^{2} =OP^{2} \\\\7^{2} +Ap^{2} =(7+18)^{2} \\\\Ap^{2} =25^{2} -7^{2} =576\\\\AP=\sqrt{576} =24\\\\Ap=24[/tex]

Use (x − 4)^2 − 28 = 8 for the following:
a. Explain why (x − 4)^2 − 28 = 8 has two solutions. (5 pts)
b. Solve the equation to find the solutions. Show your work. (5 pts)
Answer:
a) Because both sides are perfect squares b) (x-4)² – 28 = 8
(x–4)² = 36
Square root both sides
√(x–4)² = √36
x–4 = 6
x= 10
Step-by-step explanation:
(x–4)(x–4) = 36
x² – 8x+ 16 = 36
x² – 8x – 20 = 0
(x² + 2x)( –10x – 20) = 0
x(x+2) – 10(x+2) = 0
(x+2)(x–10) = 0
x = 10 or –2
x = 10
a. If the power of x is 2 then the value of x will be 2.
b. The values of the x are 6 and -2.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
Given
The equation is [tex]\rm (x- 4)^2 - 28 = 8[/tex].
a. If the power of x is 2 then the value of x will be 2. And in the equation the power of x is 2 then the solution for the x will be two.
b. The equation is [tex]\rm (x- 4)^2 - 28 = 8[/tex].
On simplifying
Add 28 both the sides, we have
[tex]\rm (x- 4)^2 = 36[/tex]
Taking square root both the sides, then we have
[tex]\rm x- 4 = \pm 6[/tex]
Add 4 both the sides,
[tex]\rm x = \pm 6+ 4\\\\x = 6 + 4, - 6 + 4\\\\x = 10 , -2[/tex]
Thus, the values of x are 6 and -2.

Scarlet made a scaled copy of the following quadrilateral. She used a scale factor greater than 1. What could be the length of the side that corresponds with AD on the scaled copy of quadrilateral.
Answer:
10 or any number >9
Step-by-step explanation:
Side AD is 9 units long so if the scale factor is greater than 1 you multiply that side by 1. This will give you a number such as 10 or 18 or any number that is greater than 9.
Verify the identity.
Please show your work.
Step-by-step explanation:
To prove :
( 1 - sin x ) ( 1 + sin x ) = sec² x
LHS : -
( 1 - sin x ) ( 1 + sin x )
Formula / Identity : -
( a - b ) ( a + b ) = a² - b²
Here,
a = 1
b = sin x
( 1 - sin x ) ( 1 + sin x )
= 1 - sin² x
Identify : -
sin² θ + cos² θ = 1
cos² θ = 1 - sin² θ
Similarly,
1 - sin² x
= cos² x

Ryan wishes to purchase a new boat and can afford monthly payments of up to $300 per month. Finance is available and the terms are that the loan lasts for 3 years, and the annual interest rate is 12%. What is the maximum price for a boat that Ryan's budget can afford? Round your answer to the nearest hundred dollars.
Answer:
$9000Step-by-step explanation:
Given
Monthly payment P = $300Time t = 3 years = 36 monthsNumber of payments n = 36Interest rate r = 12% PA = 1% per month = 0.01 timesUse loan payment formula:
P = r(PV) / (1 - (1 + r)⁻ⁿ), where P- monthly payment, PV - present value (amount of the loan), r -rate of interest, n- number of paymentsSubstitute values and solve for PV:
300 = (0.01*PV) / (1 - (1 + 0.01)⁻³⁶)PV = 300*(1 - 1.01⁻³⁶ )/ 0.01 PV = 9032.25 ≈ $9000 (rounded to the nearest hundred dollars)
