Sample A has a mean of M = 6. Sample B has a mean of M = 10. When the two samples are combined, the mean of the combined group is M = 9. Which of the following is the most accurate description for the two sample sizes?


The samples are the same size.

Sample A is much bigger than Sample B.

There is not enough information provided to determine this.

Sample B is much bigger than Sample A.

Answers

Answer 1

Answer:

Sample B is much bigger than Sample A

Step-by-step explanation:

It is because when seeing sample B alone we can see it has a larger mean than of Sample A. Mean is greater when the values we are using are of bigger value. Since Sample B has bigger values in it so it also a has bigger mean compared to Sample A which has a smaller mean (smaller values in it)

Use the distributive property to find an expression that is equivalent to
2x(x + 7)-(3x +1)

Answers

Given expression:

     2x(x + 7)-(3x +1);

To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;

  2x(x + 7)-(3x +1)  

  Distribute 2x over the first parentheses;

   the negative sign distributes over the second part

    = (2x² + 14x)  - 3x -1

    = 2x² + 14x -3x -1

    Add like terms;

    = 2x² + 11x -1

This expression  2x² + 11x -1 is equal to the given one

On a table or graph, the constant change is same as the unit rate, rate of change or slope, which can be denoted as m.

Constant change on a graph or table simply refers to the rate of change of the output (y) over the change in input (x).

Constant change in a graph or table is the same as the unit rate or the slope value which is dented by the letter m.

Use the formula to determine the number of black squares in the first five figures of the Sierpinski Carpet given by the partial sum:

For this sum:
a1 = 1
r = 8
n = 5

The number of squares in the first five figures is = 4681

Answers

Using a geometric sequence, it is found that the number of black squares in the first five figures of the Sierpinski Carpet is of 4681.

What is a geometric sequence?

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio r.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1r^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The sum of the first n terms of a sequence is given by:

[tex]S_n = \frac{a_1(1 - r^n)}{1 - r}[/tex]

In this problem, the parameters are: [tex]a_1 = 1, r = 8, n = 5[/tex], hence:

[tex]S_n = \frac{1(1 - 8^5)}{1 - 8} = 4681[/tex]

The number of black squares in the first five figures of the Sierpinski Carpet is of 4681.

Answer: Soil loss is caused by a variety of factors, including erosion from wind and water, mechanical tilling, logging, agricultural practices, and poor water management. Erosion and sedimentation, the major effects of soil loss, are widespread and can be devastating.

Erosion

Erosion is a natural process on hill slopes. The rate of erosion is determined by several factors, including soil type, rainfall, and length and percent of slope. Generally, human-induced changes in the landscape lead to higher levels of erosion than would occur naturally. While there are many ways to minimize erosion, vegetative cover is the most effective over the long term. Eroding road.When vegetation is removed, the rate of soil erosion is greatly accelerated, often beyond sustainable levels.

Sedimentation

Eroded soil deposited downslope is referred to as sedimentation. When severe rain or wind events occur or soils are disturbed by human

The Sedimentation Control Act of 1973 requires operators to implement short- and long-term mitigation measures to reduce erosion on- and off-site. Forest landowners who wish to harvest trees are exempt from these regulations if they comply with forestry practice guidelines, which include erosion control measures and mitigation. Best management practices (BMPs) are voluntary practices that reduce sources of se

What is angle?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given:

If m∠1 equals (4x + 2) and m∠3 equals (5x − 25),

According to given question we have,

m∠1 =m∠3

(4x + 2)=(5x − 25)

compare the like terms and simplify we get,

Answer:

150

Step-by-step explanation:

When you multiply a number by a percentage you have to convert the percentage to a decimal so 52% turns into 0.52. If you multiply the number of votes by 0.52 it should equal to 78. In order to find the total number of votes.  you have to go backwards and divide. So you divide 78 by 0.52 and it should give you 150.
