Given:

In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.

To find:

The length of the side KM to the nearest tenth of a centimeter.

Solution:

In a right angle triangle,

\(\cos \theta =\dfrac{Base}{Hypotenuse}\)

In the given right triangle KLM,

\(\cos K=\dfrac{KM}{KL}\)

\(\cos (35^\circ)=\dfrac{KM}{123}\)

\(0.819152=\dfrac{KM}{123}\)

Multiply both sides by 123.

\(0.819152\times 123=KM\)

\(100.755696=KM\)

\(KM\approx 100.8\)

The measure of side KM is 100.8 cm.

Therefore, the correct option is (2).

Let the numbers be x = 5x+18

3(5x+18) + 4x= 16

15x+ 54+ 4x= 16

19x = 16-54

X=-38/19

X= -2

5x+18= 5 × -2+18 = 8

The requried larger number and a smaller number is given as 8 and -2.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
According to the question,
Let the large number be y and the small number be x,
According to the question,
y = 5x + 18 - - - -(1)
4x + 3y = 16 - - - (2)

Frome quation 1
4x + 3(5x + 18) = 16
4x + 15x + 54 = 16
19x = 16 - 54
19x = -38
x = -2

Now,
y = 5(-2) + 18
y = -10 + 18
y = 8

Thus, the requried larger number and the smaller number is given as 8 and -2.

The similar shapes EFGH and JKLM have the measurement of angle Z equal to 65°, the length x = 27.5 and the length of y = 12

Similar shapes are two or more shapes that have the same shape, but different sizes. In other words, they have the same angles, but their sides are proportional to each other. When two shapes are similar, one can be obtained from the other by uniformly scaling (enlarging or reducing) the shape.

Given that the shape EFGH is a smaller shape of JKLM, and they are similar, then:

the measure of angle Z is equal to 65°

the side EF corresponds to JK and side FG corresponds to KL, so:

8/20 = 11/x

x = (11 × 20)/8 {cross multiplication}

x = 27.5

the side EF corresponds to JK and EH corresponds to JM, so:

8/20 = y/30

y = (30 × 8)/20 {cross multiplication}

y = 12

Therefore, the similar shapes EFGH and JKLM have the measurement of angle Z equal to 65°, the length x = 27.5 and the length of y = 12

In word problem , the Total bill including tax = $34.78+$2.08 = $36.86

and  you have to give server one $20 bill , one $10 bill, one $5 bill and two $1 bill, so yo don't get any pennies back.

What is word problem?

Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement. Determining whether two provided statements are equal with respect to a collection of rewritings is known as a word problem in computational mathematics.

Here the bill = $34.78

Sales tax= 6% of Bill

=> Sales tax = 6% of 34.78

=> Sales tax = \(\frac{6}{100}\times 34.78\)

=> Sales tax = $2.08

Now the Total bill including tax = $34.78+$2.08 = $36.86

Hence you have to give server one $20 bill , one $10 bill, one $5 bill and two $1 bill, so yo don't get any pennies back.

Dividend income and agricultural income are examples of tax exempt incomes.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

The right to have some or all of your income free from your country's taxes is known as a tax exemption. While certain individuals and organizations are completely exempt from paying taxes, the bulk of taxpayers are eligible for a number of exemptions that can be used to reduce their taxable income.

Income that is exempt from taxation is that which is unlikely to be taxed. Dividend income, agricultural income are a few examples.

The expression simplifies to |2x| = -2x, when x<0 by definition of absolute value

If x<0, then the expression |2x| simplifies to -2x.

The absolute value of a number is the distance of the number from zero on the number line.

Since x is negative in this case, 2x will be negative as well.

Taking the absolute value of -2x will give us the opposite of -2x, which is 2x.

However, since we know that x<0, this means that -2x will always be a positive number.

Hence, the expression simplifies to |2x| = -2x, when x<0.

Complete Question

A committee has six members. There are three members that currently serve as the​ board's chairman comma vice chairman comma and treasurer . Each member is equally likely to serve in any of the positions. Three members are randomly selected and assigned to be the new chairman comma vice chairman comma and treasurer . What is the probability of randomly selecting the three members who currently hold the positions of chairman comma vice chairman comma and treasurer and reassigning them to their current​ positions?

The probability is ?

Answer:

The probability is \(P(3 ) = \frac{ 1 }{20 }\)

Step-by-step explanation:

From the question we are told that

       The total number of members is  n = 6  

       The  number of member to be selected is  r =  3  

Generally the number of ways of selecting 3 members from 6  is mathematically evaluated as

          \(\left n } \atop {}} \right. C _r = \frac{n! }{(n-r ) ! r !}\)

=>       \(\left 6 } \atop {}} \right. C _ 3 = \frac{6 ! }{(6-3) ! 3 !}\)

=>        \(\left n } \atop {}} \right. C _r = \frac{6* 5* 4 * 3! }{3 ! 3*2 * 1}\)

=>       \(\left n } \atop {}} \right. C _r = \frac{6* 5* 4 }{3 *2 * 1}\)

=>        \(\left n } \atop {}} \right. C _r =20\)

Now the number of ways of selecting the 3 members who currently hold the position is  n  = 1

  So the probability is mathematically represented as

                 \(p(k ) = \frac{ n }{\left n } \atop {}} \right. C _r }\)

substituting values

                  \(P(3 ) = \frac{ 1 }{20 }\)

Answer:

The 84% confidence interval for the population proportion that claim to always buckle up is (0.74, 0.80).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which

z is the z-score that has a p-value of \(1 - \frac{\alpha}{2}\).

They randomly survey 387 drivers and find that 298 claim to always buckle up.

This means that \(n = 387, \pi = \frac{298}{387} = 0.77\)

84% confidence level

So \(\alpha = 0.16\), z is the value of Z that has a p-value of \(1 - \frac{0.16}{2} = 0.92\), so \(Z = 1.405\).

The lower limit of this interval is:

\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 - 1.405\sqrt{\frac{0.77*0.23}{387}} = 0.74\)

The upper limit of this interval is:

\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 + 1.405\sqrt{\frac{0.77*0.23}{387}} = 0.8\)

The 84% confidence interval for the population proportion that claim to always buckle up is (0.74, 0.80).
