It is known that the lengths of trout (centimetres) in dams in North America is Normally distributed with a standard deviation of 5 cm. For monitoring purposes, a sample of 15 trout were captured, measured and released. The sample gave a mean of 50 cm and a standard deviation of 2 cm.The 99% confidence interval for the population average length of trout isSelect one:a.(49.3 ; 50.2)b.(49.2 ; 50.9)c.(46.7 ; 53.3)d.(47.8 ; 52.3)e.(46.2 ; 53.8)

Answers

Answer 1

The average length of the trout in the area with a 99% confidence interval is between 46.7 cm and 53.3 cm.

The distribution used should be t distribution as the sample standard deviation is to be used.

We need to build the 99% confidence interval for the population mean . The following information is provided:

Sample Mean = 50

Sample Standard Deviation  = 2 cm

Sample Size = 15

The confidence interval for the trout population is computed as shown below:

[tex]\Pr \left({\bar {X}}-{\frac {cS}{\sqrt {n}}}\leq \mu \leq {\bar {X}}+{\frac {cS}{\sqrt {n}}}\right)=0.99\,[/tex]

now we will substitute the values in the equation of the CI.

[tex]{\bar {X}}-{\frac {2.7}{\sqrt {15}}}\leq \mu \leq {\bar {X}}+{\frac {2.7}{\sqrt {15}}}=0.99\,[/tex]

now solving for the confidence interval we get : 47.8 ; 52.3

Lower limit = 50 - 3.307 = 46.69 ≈ 46.7

upper limit = 50 + 3.307 = 53.307 ≈ 53.3

Hence the average length of the trout in the area is between 46.7 cm and 53.3 cm.

Can you please show me how to do this so I can teach it to my boys? They need to Express percents as fractions or mixed numbers, and to express each percent as a decimal.

Answers

A. Let's convert the following percents into a fraction or a mixed number in the simplest form.

1.) 24%

4.) 150%

To be able to convert percentage into a fraction, we just apply the following formula:

[tex]\text{ Fractional Equivalent = }\frac{\text{Percentage}}{100}[/tex]

We get,

1.) 24%

[tex]\text{ Fractional Equivalent = }\frac{\text{Percentage}}{100}[/tex][tex]\text{ = }\frac{24}{100}[/tex][tex]\text{ = }\frac{\frac{24}{4}}{\frac{100}{4}}\text{ = }\frac{6}{25}[/tex]

Therefore, the fractional form of 24% is 6/25.

4.) 150%

[tex]\text{ Fractional Equivalent = }\frac{\text{Percentage}}{100}[/tex][tex]\text{ = }\frac{150}{100}[/tex][tex]\text{ = 1 }\frac{50}{100}\text{ = 1}\frac{1}{2}[/tex]

Therefore, the fractional form of 150% is 1 1/2.

B. Express each percent as a decimal.

9.) 8%

14.) 568%

To be able to convert a percentage to a decimal, we just divide all percentages by 100.

[tex]\text{Decimal Equivalent = Percentage }\div\text{ 100}[/tex]

9.) 8%

[tex]\text{Decimal Equivalent = Percentage }\div\text{ 100}[/tex][tex]\text{ = 8 }\div\text{ 100}[/tex][tex]\text{ Decimal Equivalent = 0.08}[/tex]

14.) 568%

[tex]\text{Decimal Equivalent = Percentage }\div\text{ 100}[/tex][tex]\text{ = 568 }\div\text{ 100}[/tex][tex]\text{ Decimal Equivalent = 5.68}[/tex]

Therefore, the decimal equivalent of 568% is 5.68.

Circle C and circle J are congruent, what is NM?

Answers

Ok, so

We know that two circles are congruent. This makes that the triangles there, are cogruent.

Let me draw the situation here below:

If both triangles are congruent, that means that their sides and angles are equal.

Now if we notice, we realize that side DG and side NM will be equal.

So, DG = NM

Which is the same that

14t - 26 = 5t + 1

If we solve the equation for t:

14t - 5t = 26 + 1

9t = 27

And t = 3

Now, we want to find NM measure.

And we just have to replace t=3 in the expression 5t+1

This will be 5(3) + 1, which is 16.

Therefore, NM measures 16.

find the area of a regular 18-gon with radius of 14 mmA≈ __ mm squared do not found until the final answer, then round to the nearest tenth as needed.

Answers

ANSWER

EXPLANATION:

Given that;

The radius of the 18-gon is 14mm

Follow the steps below

Step 1; Calculate the interior angle by using the below formula

[tex]\text{ }\theta\text{ = }\frac{\text{ 180 \lparen n - 2\rparen}}{n}[/tex]

Since the polygon has 18 sides, then n = 8

[tex]\begin{gathered} \text{ }\theta\text{ }=\text{ }\frac{180\text{ \lparen18 - 2\rparen}}{18} \\ \\ \theta\text{ }=\text{ }\frac{180\text{ }\times\text{ 16}}{18} \\ \\ \theta\text{ }=\text{ }\frac{2880}{18} \\ \theta\text{ }=\text{ 160}\degree \end{gathered}[/tex]

Step 2; Find the base angle of the triangle

Recall, that all regular polygon can be divided into isosceles triangle by joining the vertices to the center. Hence, the base angle can be calculated below as

[tex]\begin{gathered} \text{ Base angle = }\frac{160}{2} \\ \text{ Base angle = 80}\degree \end{gathered}[/tex]

Step 3; Find the height of triangle using trigonometric

[tex]\begin{gathered} \text{ tan }\theta\text{ }=\text{ }\frac{\text{ opposite}}{\text{ adjacent}} \\ \text{ } \end{gathered}[/tex]

Since the radius of the polygon is 14mm, therefore, the base length is

[tex]\begin{gathered} \text{ Base length = }\frac{14}{2} \\ \text{ Base length = 7mm} \end{gathered}[/tex][tex]\begin{gathered} \text{ Tan 80 = }\frac{h}{7} \\ \text{ cross multiply} \\ \text{ h = tan 80 }\times\text{ 7} \\ \text{ h = 7tan 80} \\ \text{ tan 80 = 5.671} \\ \text{ h = 7 }\times\text{ 5.671} \\ \text{ h = 39.697 mm} \end{gathered}[/tex]

Step 4; Find the area of the triangle

[tex]\begin{gathered} \text{ Area of a triangle = }\frac{1}{2}bh \\ \text{ Area of a trianlge = }\frac{1}{2}\times7\times39.697 \\ \text{ Area of a triangle = }\frac{277.879}{2} \\ \text{ Area of a triangle = 138.94 mm}^2 \end{gathered}[/tex]

Step 5; Find the area of the polygon

Since there are 18 triangles in the polygon, then calculate the area of the 18-gon

Area of 18-gon = 18 x 138.94

Area of 18-gon = 2500.9 mm^2

Therefore, the area of the 18-gon is 2500.

Answers

SOLUTION

(33) The question says a coin is tossed and a die with 6 faces is rolled, what is the probability of getting a head and a 3.

Probability is given as

[tex]Probability=\frac{expected\text{ outcome}}{total\text{ outcome }}[/tex]

Now, a coin has two faces, a head and a tail. So, total outcome is 2 faces.

We want to get the probability of getting a head. This becomes

[tex]\begin{gathered} Probability\text{ of head = }\frac{expected\text{ outcome}}{total\text{ outcome}}=\frac{1\text{ head}}{2\text{ faces}} \\ =\frac{1}{2} \\ P(head)=\frac{1}{2} \end{gathered}[/tex]

So, probability of getting a head is 1/2

A die has 6 faces labelled 1, 2, 3, 4, 5 and 6

Probability of getting a 3 should be

[tex]\begin{gathered} Probability\text{ of getting 3 = }\frac{one\text{ face showing 3}}{6\text{ faces}} \\ that\text{ is }\frac{1}{6} \end{gathered}[/tex]

So, probability of getting a 3 is 1/6

Now probability of getting a head and a 3, that is P(head and 3), means we multiply both probabilities, we have

[tex]\begin{gathered} P(head\text{ and 3\rparen = }\frac{1}{2}\times\frac{1}{6} \\ =\frac{1}{12} \end{gathered}[/tex]

Hence the answer is

[tex]\frac{1}{12}[/tex]

Can decimals be constants?

Answers

Constants refer to a number and a decimal is a number expressed in decimal notation, therefore, decimals can be constants.

What is a decimal?

A decimal number is the expression of a fraction in terms of the quotient of the fraction, for example, 1/4 in decimal form is 0.25.

The standard form or system for representing numbers that are integers and numbers that are non integers is the decimal number system which is based on the Hindu-Arabic number system.

When numbers (integers and non integers) are expressed as decimals, the numbers are cited as being in decimal notation.

The location of a number in decimal notation is between the ones and tenth place of the number.

A constant is a value in an expression or equation that remains the same in an equation.

A constant is therefore expressed quantitatively as a number.

Therefore, decimals, which are also numbers can be constants.

If a set of grades for a class has a large range and a small standard deviation,what can you say about the class? Include an interpretation that is specific togrades in a class.

Answers

A large ranges indicates that there is a large difference between the highest and lowest grade scores. A smaller deviation indicates that the grades scores are less varied amom themselves.

An example is when the highest grade is 100 and the lowest grade is 5. In this case the range is larger than the case when the highest is 100 and the lowest 60.

A smaller standard deviation means that the data set of grades are close to the mean of the data set. The behavior is the following

Answers

The described transformation is a translation and a reflection that is dilation.

By rotating, reflecting, or translating a shape on a coordinate plane, a transformation is made.

The transformation, i.e., f: X X, is a function, f, that maps to itself. Following the transformation, the pre-image X changes into the image X. Any operation, including translation, rotation, reflection, and dilation, may be used to create this transformation. A function can be moved in one direction or another by translation, rotated around a point by rotation, reflected in its mirror image by reflection, and scaled by dilation.

The dilation is the transformation that causes the 2-d shape to stretch or contract vertically or horizontally by a fixed amount. The equation y = a.f. yields the vertical stretch (x). The function stretches in relation to the y-axis if a > 1.

A function is a relation where each element of a set (A) corresponds to one and only one element of another set (B).

Therefore, the only value in x that is repeated is -2, therefore the answer (-2, 0)

What is a discrete set?Is option d and e and possibly c?

Answers

Discrete sets are sets which members are countable and distinct.

That is, they are separable and can only have a certain value.

For example, the number of players in a rugby team is discrete because they are countable.

Hence, options C, Dare applicable.
