Murrr4er [49]

Answer: $H_0: p\geq0.158\\\\ H_a:p$

Step-by-step explanation:

Let p be the population proportion of adults who were surveyed are current smokers.

Given claim : Abigail, who works for a region's department of health, is looking for evidence that the percentage of adults in the region who are current smokers has decreased from 15.8% in 2015.

i.e. $p$

Since the alternative hypothesis takes unequal sign .

Then , the null and alternative hypotheses for this hypothesis test will be :_

$H_0: p\geq0.158\\\\ H_a:p$

While on a walk in the country, you pass a field of goats and chickens. After a quick count, you determine there are 38 heads an

Neko [114]

Answer:there are 16 goats and 22 chickens.

Step-by-step explanation:

Let x represent the number of goats in the field.

Let y represent the number if chicken in the field.

After a quick count, you determine there are 38 heads and 108 feet in the field. A goat has one head. A chicken also has one head. It means that

x + y = 38

A goat has four legs. A chicken has 2 legs. It means that

4x + 2y = 108 - - - - - - - - - - - 1

Substituting x = 38 - y into equation 1, it becomes

4(38 - y) + 2y = 108

152 - 4y + 2y = 108

- 4y + 2y = 108 - 152

- 2y = - 44

y = - 44/ - 2

y = 22

x = 38 - y = 38 - 22

x = 16

Write 24:14:6 in its simplest form.

Iteru [2.4K]

Answer:

12 : 7 : 3

Step-by-step explanation:

24 : 14 : 6

12 : 7 : 3

Always start with smaller number to simplify it. Since 2 is the smaller number and it simplifies 24, 14, and 6 I start with it.

24 ÷ 2 = 12

14 ÷ 2 = 7

6 ÷ 2 = 3

We would stop here since it would not further simplify, therefore our answer is 12 : 7 : 3.

Hope this helps, thank you :) !!

Which of the following is a way in which statistics are made to be misleading?

hodyreva [135]

The statistics are made to be misleading in such a way that the scale is altered on the graph. So, option C is correct.

<h3>What are statistics?</h3>

Statistics is the study of the discipline that concerns the organization, collection, analysis, and presentation of data.

A hasty generalization is fallacy in which a conclusion is reached before sufficient or unbiased evidence is gathered.

The statistics are made to be misleading in such a way that the scale is altered on the graph. So, option C is correct.

ABC is an equilateral triangle .Three distinct points are marked on each sides of the triangle. (not on the vertices). (i) How m

iVinArrow [24]

The number of lines and triangles illustrates combination

36 lines can be drawn to join the nine points
84 triangles can be drawn using the nine points

<h3>The number of lines that can be drawn</h3>

The given parameters are:

Total points, n = 9

Total points on each line, r = 2

The number of lines that can be drawn is then calculated using the following combination formula

Lines = nCr

This gives

Lines = 9C2

Evaluate the combination expression

Lines = 36

Hence, 36 lines can be drawn to join the nine points

<h3>The number of triangles that can be drawn</h3>

The given parameters are:

Total points, n = 9

Total points on each triangle, r = 3

The number of triangles that can be drawn is then calculated using the following combination formula

Triangles = nCr

This gives

Triangles = 9C3

Evaluate the combination expression

Triangles = 84

Hence, 84 triangles can be drawn using the nine points
