A movie channel sends an email survey to all customers who purchase their service each month. The previous month, 182,000 people purchased
subscriptions. Surveys were sent to 9,000 of these people, chosen at random, and 1,080 people responded to the survey. Identify the population and the
sample.
The population is 182,000 and the sample is 1,080.
The population is 9,000 and the sample is 1,080.
The population is 182,000 and the sample is 9,000.
The population is 9,000 and the sample is 182,000.
Answer:
The population is 9,000 and the sample is 1,080
Step-by-step explanation:
Your population is 9,000 because that is how many people got the survey. The number 182,000 is irrelevant because that information does not matter with regards to the surveys. Your sample is 1080 because that is the number of people that responded.

Answer:
y is equal to 7 when x is equal to 14.
Step-by-step explanation:
-6 divided by -3 is equal to 2. This means x divided by y is equal to 2.
x / y = 2

Write the first six terms of the sequence.
a1 = 4, an = An-1 +5
Answer:
{4, 9, 14, 19, 24}
Step-by-step explanation:
Best to use the notation a(1) = 4, a(n) = a(n-1) + 5.
a(1) = 4 (given)
a(2) = 9 (here we found a(2) by adding the common difference, 5, to a(1)
a(3) = 14

The annual rainfall for two cities, Albany and Zachary, in each of the years from 2002 to 2011 are shown in the tables. Annual Rainfall for Albany (in.) 23.36 18.51 28.54 22.36 30.50 24.74 11.93 15.34 18.07 15.98 Annual Rainfall for Zachary (in.) 27.27 20.11 31.14 25.88 32.97 25.03 18.55 23.91 22.75 19.73 Find the mean for the two cities' annual rainfalls. In which city does it rain more in a year, on average? Drag and drop the correct choices into the boxes to complete the statement. On average, Albany gets _ inches of rain per year and Zachary gets _ inches of rain per year. on average, which city rains more zachary or albany?
Answer:
On average, Albani gets 20.933 inches of rain per year.
On average, Zachary gets 24.734 inches of rain per year.
On average, Zachary gets more rain than Albani.
Step-by-step explanation:
Mean is given by:
[tex]Mean = \frac{Sum}{Total}[/tex]
For Albani :
Sum of total number of terms = 23.36+18.51+28.54+22.36+30.50+24.74+11.93+15.34+18.07+15.98
Sum of total number of terms = 209.33
Number of terms = 10
[tex]Mean=\frac{209.33}{10}\\\\Mean=20.933\\[/tex]
For Zachary :
Sum of total number of terms = 27.27+20.11+31.14+25.88+32.97+25.03+18.55+23.91+22.75+19.73
Sum of total number of terms = 247.34
Number of terms = 10
[tex]Mean=\frac{247.34}{10}\\Mean=24.734[/tex]
What is the smallest and largest perimeter of a polygon with an area of 20?
Answer:
The polygon with the smallest perimeter is the megagon
The polygon with the largest perimeter is the triangle
Step-by-step explanation:
An equilateral triangle with area = 20 has
0.5× a²×sin60 = 20
a= 6.796
Hence, perimeter = 20.39
A square of area 20 has perimeter= 4×√20 = 17.9
A regular pentagon of area = 20 has perimeter = 3.41 × 5 = 17.05
Hence as the number of sides is increasing, the ratio of the Area to the Perimeter also increases
Therefore, a triangle has the largest perimeter with an area of 20 while a megagon with a million sides has the smallest perimeter with an area of 20.
The perimeter of a triangle is 27 feet. One side is 3 feet longer than the shortest side, and the longest side is twice as long as the shortest side. How long is each side?
Answer:
6, 9, 12
Step-by-step explanation:
Let s be the shortest side. Using the information you're given, you can create an equation. 27= s + s+3 + 2s. Now just solve the equation. Subtract 3 from both sides. 24=4s. Divide by 4 on both sides. 6=s. So the shortest side is 6 feet long, so we add 3 to that for the one that is neither the shortest or the longest. That side is 9 feet long. We double s to get 12, which is the longest side.
Answer:
Long side: 12
Middle side: 9
Shortest side: 6

A cylinder of base radius 4cm is opened at one end . If the ratio of the area of it's base to that of it's curved surface area is 1:4, Calculate the height of the cylinder
Answer:
Height = 8cm
Step-by-step explanation:
I hope it helps
The required height of the cylinder is 8cm.
A cylinder of base radius 4cm. The ratio of the area of it's base to that of it's curved surface area is 1:4. Height of cylinder is to be determine.
Surface area is defined as the area of the surface that are uncovered.
Here,
area of circle/surface area of cylinder=1/4
πr²/2πrh=1/4
r/2h=1/4
h=2r
where r = 4cm
h = 2*4
h = 8cm
Thus, the required height of the cylinder is 8cm.

Answer:
Option B, C and E are supplementary angles.
Step-by-step explanation:
We need to find supplementary angles.
Supplementary angles are those angles who sum up to 180 °.
I have attached picture for reference.
Looking at the figure given:
We have supplementary angles:
∠4 and ∠3
∠4 and ∠5
∠5 and ∠6
∠7 and ∠8
∠3 and ∠6
But the options given are: ∠4 and ∠3,∠4 and ∠5, ∠3 and ∠6
So, Option B, C and E are supplementary angles.
Supplementary angles are pair of adjacent angles that add up to 180 degrees
Conditions for supplementary anglesFor a pair of angles to be supplementary, then the following must be true
The angles must be adjacent i.e. side by sideThe angles must add up to 180 degreesThe image is not given.

30

60
Answer:
Option (2)
Step-by-step explanation:
Measure of angle formed by two tangents from a point outside the circleis half the difference of the measures of the intercepted arcs.
From the figure attached,
m∠C = [tex]\frac{1}{2}[m(\text{major arc AB})-m(\text{minor arc AB)}][/tex]
= [tex]\frac{1}{2}[(360-m\widehat{AB})-m(\widehat{AB})][/tex]
= [tex]\frac{1}{2}[360-2m(\widehat{AB})][/tex]
= [tex]180-m\widehat{AB}[/tex]
= 180 - 150
= 30°
Therefore, measure of angle C will be 30°.
Option (2) is the answer.
(q^4)^z=q^12
find the value of z
Answer:
z = 3
Step-by-step explanation:
Using the rule of exponents
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Thus
[tex](q^{4}) ^{z}[/tex] = [tex]q^{4z}[/tex] , so
[tex]q^{4z}[/tex] = [tex]q^{12}[/tex]
Since the bases on both sides are equal then equate the exponents
4z = 12 ( divide both sides by 4 )
z = 3
Answer:
The value of z is 3.
Step-by-step explanation:
You have to use Indices Law,
[tex] {( {a}^{m}) }^{n} \: ⇒ \: {a}^{mn} [/tex]
So for this question, first you have to get rid of brackets :
[tex] { ({q}^{4} )}^{z} = {q}^{12} [/tex]
[tex] {q}^{4z} = {q}^{12} [/tex]
Next you can solve it since both have the same bases :
[tex] {q}^{4z} = {q}^{12} [/tex]
[tex]4z = 12[/tex]
[tex]z = 3[/tex]

Answer: [tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
Formula : Probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]
Given , Sam has 4 cards numbered 2,3,5, and 7.
His friend has 4 cards numbered 1,2,6 and 7.
If they both draw one card and put that on table , then the possible combinations of cards would be (2,1) , (2,2), .... (7,6), (7,7).
i.e. Number of possible outcomes would be (S) 4 x 4 = 16
Favorable outcomes that they will choose same number (F) = (2,2) , (7,7)
Now , the probability that they will both choose the same number would be :
[tex]\dfrac{F}{S}=\dfrac{2}{16}=\dfrac{1}{8}[/tex]

Ugh Summer work...Pls Help Me! 4.25 - x = 14.13

Answer:
-9.88.
Step-by-step explanation:
1. Write it out.
4.25-x=14.13
2. Make it a bit easier to read.
4.25-x=14.13 is also the same thing as... -x+4.25=14.13. Now it's easier to tell that 4.25 is positive.
3. Isolate x and get it by itself.
Since we have a number on x's side, we have to move it to the other side. The opposite of addition is subtraction, so we subtract 4.25 by both sides!
-x+4.25=14.13
-4.25 -4.25
-x=9.88
Technically, x can't really be negative, so we can just divide by negative one on each side to get rid of the negative x.
-x=9.88
/-1 /-1
x=-9.88
That's finally the answer and sorry if the explanation took forever! Hope you understand :)
