ProportionsGiven that Netflix is considering a new romcom (romantic comedy) series, and a random sample of 1,000 viewers was selected and 625 viewers indicated they would watch the new series, for A) estimate the value of the population proportion of people who would watch the new series, and B) develop a 99% confidence interval for the population proportion of people who would watch the new series, the following calculations must be made:
A)
625 = 1
1000 = X
1000 / 625 = X
1.6 = X
10 out of 16, or 5 out of 8.
B)
62.5 x 0.99 = 61.875
62.5 x 1.01 = 63.125
Therefore, A) the value of the population proportion of people who would watch the new series is 5 out of 8 viewers, and B) a 99% confidence interval for the population proportion of people who would watch the new series indicates that between 61.87% and 63.13% of viewers will watch the new series.

write x^2-4x+2 in the form (x-A)^2+B
Answer:
(x-2)^2-2
Step-by-step explanation:
x^2-4x+2
take the x out
x(x-4) + 2
(x-2)^2-2
because (x-2)^2 is
x^2-4x+4
its like completing the square
Answer:
(x-2)² -2
Step-by-step explanation:
Consider that (a+b)² = a²+2ab+b²
To find the form (x-A)²+B compare x²-4x+2 with a²+2ab+b²
x² - 4x +2
a² + 2 a b+ b², so a= x and b = (-2)
x²+ 2· x ·(-2)+ (-2)² - 2 = (x-2)² -2 is in the form (x-A)²+B
Check our answer:
(x-2)² -2= (x²-2·2x+4)-2 = x²-4x +2 ✅
At another park in Chicago, neighbors get together to plan a community garden. Plans for the community garden are shown below. celery tomatoes 6 yds spinach carrots watermelon 12 yds red peppers 8 yds a) The members of the gardening group plan to build a walkway through the garden as formed by the hypotenuse of each of the four triangles in the drawing. That way, the gardeners will be able to access all sections of the garden. Calculate the length of the entire walkway to the nearest hundredth of a yard. Show your work. (4 points-1 point for each length calculation and 1 point for the total distance) *** 15 yds
Answer:
we can use the pythagorean theorem to each of those right triangles to find the lengths of the pathways
Step-by-step explanation:
for the spinach celery walkway,
d=[tex]\sqrt{6^{2}+8^{2}[/tex] = 10 yd
for each watermelon walkway,
d=[tex]\sqrt{8^{2}+12^{2}[/tex] = 14.42 yd
from the carrots red peppers walkway,
[tex]b^{2}+12^{2} = 15^{2}[/tex]
b=[tex]\sqrt{15^{2}-12^{2}[/tex]= 9yd
for each tomatoes walkway;
d=[tex]\sqrt{6^{2}+9^{2}[/tex] = 10.82 yd
so the total length of the walkway is = 10+14.42+15+10.82 = 50.24 yd

Hey! pls help me with this question on angles. would really be appreciated. have a nice day.
Using supplementary angles, it is found that the measures of the angles are given as follows:
m<a = 30º.m<b = 90º.What are supplementary angles?Supplementary angles are two angles whose sum is of 180º.
An interior angle is supplementary with it's exterior angle, hence:
m<a + 150º = 180º -> m<a = 30º.
The sum of the three interior angles of a triangle is of 180º, hence:
30º + m<b + 60º = 180º
90º + m<b = 180º
m<b = 90º.

How do I do the math here? I am not sure how to set it up with having only one angle to work with.
Answer:
angle A = 112 degrees
Step-by-step explanation:
Angle ADC is bisected (given) ...so angle 1 = angle 2
then angle D = 68 degrees
now you have to remember that adjacent corners (angles on the same LEG) of a trapezoid sum to 180 (they are 'supplementary' )
angle A = 180 - 68 = 112 degrees

You invested money in two funds. Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $858. This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $867. How much money did you invest in each fund?
The amount that was invested in the first fund is $8300.
The amount that was invested in the second fund is 3700.
What are the linear equations that represent the question?0.09a + 0.03b = $858 equation 1
0.1a + 0.01b = $867 equation 2
Where:
a = amount invested in the first fund b = amount invested in the second fund How much was invested in the second fund?Multiply equation 2 by 0.9:
0.09a + 0.009b = 780.30 equation 3
Subtract equation 1 from equation 3
0.021b = 77.70
Divide both sides by 0.021
b = $3700
How much was invested in the first fund?
Substitute for b in equation 1: 0.09a + 0.03(3700) = $858
0.09a + 111 = 858
a = (858 - 111) / 0.09
a = $8300

How to determine the covered area?The amount of area to cover is given as:
Covered area = 3/5
Express as percentage
Covered area = 3/5 * 100%
Divide 3 by 5
Covered area = 0.6 * 100%

Manny buys a new grill that costs $375. The grill is discounted 22% and sales tax is 6.5%. How much does Manny pay for the grill? ( NEED HELP ASAP!!)
Answer:
$310.05
Step-by-step explanation:
Method 1: Find the amount of 22% discount and subtract from original price, and find the amount of 6% tax and add to discounted price.
Original price: $375
Discount of 22%
22% of $375 = 0.22 × $375 = $82.50
Price after discount (but before tax): $375 - $82.50 = $292.50
Sales tax of 6%
6% of $292.50 = 0.06 × $292.50 = $17.55
Price after discount and tax: $292.50 + $17.55 = $310.05
Method 2: Add and subtract the discount percent and the tax percent first, then multiply.
Original price: $375
The discount is 22%.
The original price is 100%.
Subtract 22% from 100%: 100% - 22% = 78%
The discounted price is 78% of the original price.
Once you have the discounted price, tax is 6%.
The new discounted price is 100%. Add 6% to get 106%.
The price with tax is 106% of the discounted price.
106% of 78% of $375 = 1.06 × 0.78 × $375 = $310.05
Answer: $310.05
