Suppose the slope of a line is positive. Describe what happens to the graph of the line as you move from left to right?

In the left column: how was the numerical part of the answer found (addition, subtraction )

Setler79 [48]

You can find the numerical part of the answer because it is the same on the right side.

For example:
¹ <<==== Regrouped
89
+
67
---------
146 <<=== I had to press space so I could position it.

So that also happens in subtraction, the left side can be found by doing the same steps in the right column.
For example:

67
- <<=== this time there was no regrouping
12
-------
55

A hotel has 30 floors with 40 rooms per floor. The rooms on one side of the hotel face the water, while rooms on the other side

Ket [755]

A) Choosing a stratified random sample might be preferable to an SRS because;

Stratified random sampling would divide the population into stratas but the

SRS would not do so. The strata would be the type of room namely those

with water view and those with golf view.

B) The reason why a cluster sample would be a simpler option is because;

It will divide the population into multiple clusters that makes it easier to

work with unlike the SRS that generalizes. The clusters would be each of

the 30 floors.

We are told that the manager wanted to select 120 rooms and carry out a survey on each registered guest by asking how satisfied they were with the hotel. He decided to use a sampling method called SRS which means Simple Random Sampling.

Simple random sampling is defined as a sampling method where individuals or objects are selected randomly from a population thereby given each person or object an equal chance of selection.

A) Stratified Random sampling is a method of sampling that divides the population into smaller groups known as objects/stata. In this case Stratified random sampling would be preferred to SRS because the hotel rooms are divided into two types namely those that can view the water and those that can view the golf course and as such the Stratified random sampling would divide the population but the SRS would not do so.

B) Cluster sampling is when the population is divided into multiple groups known for assessment. The reason why it would be a simpler option is because there are 30 floors and they can be classified as clusters and surveyed per floor.

Which best describes the data set?

MAXImum [283]

Answer:

The answer is C

Step-by-step explanation:

It is nonlinear but you have to look at it compared to the months passed. In three months the total houses built are 33 this would mean each month they build 11 houses but in the fourth month they have built 46 houses because 46-11 dosnt equal 33 it is nonlinear.

Maria mixes \frac{1}{4} cup white sugar and \frac{2}{3} cup brown sugar to make a topping for some muffins. She uses \frac{1}{12

Hoochie [10]

Answer: 11 muffins

Step-by-step explanation:

Since Maria mixes 1/4 cup white sugar with 2/3 cup brown sugar, this will give us a mixture of:

= 1/4 + 2/3

= 3/12 + 8/12

= 11/12

Ww are then told that she uses 1/12 cup of the mixture to top each muffin. Therefore, the number of muffins that she can top will be:

= 11/12 ÷ 1/12

= 11/12 × 12/1

= 12

She can top 11 muffins.
