Identify which type of sampling is used: random, systematic, convenience, stratified, or cluster. To determine customer opinion of their safety features, Daimler−Chrysler randomly selects 100 service centers during a certain week and surveys all customers visiting the service centers.

Answers

Answer:

Cluster

Step-by-step explanation:

According to the Question,

Given this, Daimler−Chrysler randomly selects 100 service centers during a certain week and surveys all customers visiting the service centers.

This is a Cluster type of Sampling.

Cluster sampling is a type of sampling method in which the population under study is divided into different groups known as clusters before simple random samples are selected from each population cluster. The analysis of such a population is carried out based on the sampled clusters. This method is adopted when a researcher does not have access to the whole population under research.

Advantages of cluster sampling

The research method only needs fewer resources. The sample under review is feasible.

Note: Cluster sampling is not as accurate as simple or stratified random sampling.

Answers

Answer:

Step-by-step explanation:

x + 2y = 9

x = - 2y + 9

2x + 4y = 20

2(-2y + 9) + 4y = 20

-4y + 18 + 4y = 20

-4y + 4y = 20 - 18

What is the equation of the line in slope-intercept form?

Answers

Answer:

2) y=-3x+36

Step-by-step explanation:

Hi there!

We're given a graph and we want to find the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We'll need two points, so pick any two from the graph

For example, let's do (0,36) and (12,0)

first let's find the slope

The formula for the slope calculated from two points is (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are points

we'll be using (0,36) and (12,0)

let's label the points to avoid any confusion

x1=0

y1=36

x2=12

y2=0

Now substitute into the formula:

m=(y2-y1)/(x2-x1)

m=(0-36)/(12-0)

m=-36/12

m=-3

so the slope is -3

here's the equation so far:

y=-3x+b

we need to find b

The equation of the line will pass through both (0,36) and (12,0) so we can use either one of them to solve for b

let's take (12,0) for example

substitute 12 as x and 0 as y

0=-3(12)+b

multiply

0=-36+b

add 36 to both sides to isolate b

36=b

now substitute 36 as b into the equation

y=-3x+36

There's the equation of the line, so the answer is option 2

Hope this helps!

2. (4,12) (6,21) (8,0)

4. (12,12) (18,21) (24,0)

Answers

Answer:

(12, 12), (18, 21), (24, 0)

Step-by-step explanation:

To dilate a figure, you multiple each of the numbers in its coordinates by the scale factor.

The vertices of the new triangle is:

4. (12,12) (18,21) (24,0)

What are the vertices of the new triangle?

We have:

The vertices of a triangle: (4, 4) (6,7) and (8,0)

We dilate the triangle by a scale factor of 3

To find the vertices of the new triangle after a dilation of 3, multiply the old vertices by 3. That is:

3 * (4, 4) => (12, 12)

3 * (6, 7) => (18, 21)

3 * (8,0) => (24, 0)

Therefore, the vertices of the new triangle is (12,12) (18,21) (24,0)

In a certain region, there is a 0.1 probability that any checked passerine bird's nest will
contain a cuckoo egg. If three passerine nests are checked, what is the probability that
at least two of them contain a cuckoo egg?

Answers

Answer:

Probability of at least two cuckoo eggs is 0.738.

Step-by-step explanation:

probability of cuckoo egg = 0.1

probability of not a cuckoo egg = 1 - 0.1 = 0.9

Probability of at least two cuckoo eggs is

= Probability of two cuckoo eggs x probability of 1 not cuckoo egg +

probability of three cuckoo eggs

= 0.1 x 0.1 x 0.9 + 0.9 x 0.9 x 0.9

= 0.009 + 0.729

= 0.738

what is the largest number in the form x987yz that is divisible by 12?

Answers

Answer:

998796

Step-by-step explanation:

For a number to be divisible by 12. it must be divisible by 3 and 4

Since we need the largest 6 digit number, we will take x = 9

So the number is 9987yz

Again since we need the largest number we will consider the largest 2 digit number multiple of 4 and 3.

Largest 2 digit number divisible by 4 is 96, which is also divisible by 3.

So, yz = 96

Therefore , the largest number in the form will be : 998796

Answer:

The largest number is 998796

------------------------------------------------------

The largest digit you could use is 9 so, our number would be, 998799,

but the thing is that it's not divisible by 12.

The next largest would be 8. (998798) Not divisible.

7, so our number would be, 998797. Not divisible.

6, 998796. 998796/12= 83233, which means that it is divisble, so, the largest number in the form x987yz that is divisble by 12 is 998796

Solve for the value of v

Answers

Answer:

v = 9 because it is what would make a great answer

Step-by-step explanation:

the angles are supplementary, meaning it sums up to 180 degrees

so to find v, you have to find the total angle of v.

180- 105 equals 8v+3, or 75 equals 8v+3

subtract 75 with 3 leaving 72 equals 8v

v would equal 9

The Howards bought a $224,000 townhome. They made a down payment of $45,000 and took out a mortgage for the rest. Over the course of 30 years they
made monthly payments of $1073.21 on their mortgage until it was paid off.
th
total amount they ended un naying for the townhome

Answers

1 year = 12 months.

30 years x 12 months per year = 360 total months

Multiply total months by monthly payment:

360 months x 1,073.21 per month = $386,355.60 total monthly payments for 30 years.

Now add the down payment to the total monthly amount:

$386,355.60 + $45,000 = $431,355.60
