Now, we know

By, sine rule:

Now, we know N

A + B + C = 180 c°°

43 + B + 79° = 180°°

B = 180° - 799 - 43°°

B = 58°

Now, Side b =

Final Answer -

∠B = 58B°

∠C = 797°

Side, b = 3.1 cm

Answer: y = -x + 3

Step-by-step explanation:

y = mx + b

We need to find the slope of the equation first.

Change in y: 7 - 0 = 7

Change in x: -4 - 3 = -7

Slope = Change in y / Change in x

slope = 7 / -7 = -1

Now, plug the slope into the equation to find b.

0 = -1(3) + b

b = 3

or 7 = -1(-4) + b

b = 3

Using the binomial distribution, the mean and the standard deviation for the number of settled complaints among those received are given as follows:

The binomial distribution gives the probability of exactly x successes on n repeated trials, with p probability of a success on each trial. These parameters will be used to find the mean and the standard deviation, with formulas that are presented next.

The mean is given as follows:

[tex]E(X) = np[/tex]

The standard deviation is given as follows:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Considering that a sample of 200 complains are chosen, each with an 90% probability of being settled, the parameters are given as follows:

n = 200, p = 0.8.

Hence the mean is:

[tex]E(X) = np = 200 \times 0.8 = 160[/tex]

The standard deviation is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{200 \times 0.8 \times 0.2} = 5.66[/tex]

The problem states that 200 complaints were received, and asks for the mean and the standard deviation for the number of settled complaints among those received.

The value of the independent variable does not rely on the values of the other variables in an expression or function, and its value determines the values of the other variables.

An independent variable can be defined as the variable that is being manipulated, controlled, and which varies in an experimental or research study for the exploration of its effects.

It is termed “independent” because it's not affected or changed by other variables in an experiment or study.

It is known as a variable that is unaffected in a function and cannot be determined by the other variables in that function.

The length and width of the rectangle with a perimeter of 378ft are 168ft and 21ft respectively.

The formula used in calculating the perimeter of a rectangle is expressed as;

P = 2( l + w )

Where l is length and w is width.

Given the data in the question;

Let 'x' represent the width of the rectangle.

Plug the given values into perimeter formula and solve for x .

P = 2( l + w )

378 = 2( 8x + x )

378 = 2( 9x )

378 = 18x

18x = 378

x = 378/18

x = 21

Now, we find the length and width of the rectangle.

Width of the rectangle w = x = 21ft

Length of the rectangle l = 8x = 8( 21 ) = 168ft

Therefore, the width of the rectangle is 21ft while its length is 168ft.

Considering the definition of greatest common divisor, the greatest number of backpacks volunteers can prepare using all of the maps and dictionaries is 8.

Considering that a divisor can be formally defined as that number that is contained in another exactly n times, the greatest common divisor is the largest number by which two or more numbers can be divided. That is, the greatest common factor is the highest number by which a set of numbers can be divided, resulting in a whole number.

To calculate the greatest common factor, the following steps must be followed:

In this case, you must calculate the greatest common factor as follows:

2 is the factor common to both numbers, with 3 being the smallest exponent found. Then the greatest common divisor is calculated as:

Answer:

First, let one angle be a variable (eg: x) so that you can form expressions and solve.

Let the first angle be x°.

Then we can form expressions for the second and third angles using the information given.

First angle = x°

Second angle = (x + 10)°

Third angle = (3x)°

Since sum of angles in a triangle is 180°, we can form an equation.

x + (x + 10) + 3x = 180

Simplify and solve for x.

5x + 10 = 180

5x = 170

x = 34

Substitute x into the expressions to find the angles.

First angle = 34°

Second angle = 34 + 10

= 44°

Third angle = 3(34)

= 102°

Explanation:

r = correlation coefficient

The r values are within the interval [tex]-1 \le r \le 1[/tex]

In other words, r is between -1 and 1 inclusive of both endpoints.

For the case r = 0.013, it's very close to r = 0. This suggests there is very weak positive correlation or practically no linear correlation at all.

The x and y solution of the system  is x = -3 and y = -6

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

6 = −4x + y

− 5x − y = 21

Make -y the subject in the second equation, by adding 5x to both sides of the equation

5x − 5x − y = 21 + 5x

This gives

−y = 21 + 5x

Substitute −y = 21 + 5x in 6 = −4x + y

6 = −4x - 21 - 5x

Evaluate the like terms

5x + 4x = -6 - 21

This gives

9x = -27

So, we have

x = -3

Substitute x = -3 in −y = 21 + 5x

−y = 21 + 5 * -3

Evaluate

−y = 6

So, we have

y = -6

Hence, the solution for the system of linear equations 6 = −4x + y and − 5x − y = 21 is x = -3 and y = -6

If a = b and b = c then a = c ; Transitive Property

If a = b then a ÷ c = b ÷ c; Division property of =

a = a; Reflexive property

If x + a = b and x = c then c + a = b; Substitution Property

If a = b then a + c = b + c; Addition Property of =

If a = b then a•c = b•c; Multiplication Property of =

If a•b = a•c then a•c = a•b Symmetric Property

a•(b + c) = a•b + a•c; Distributive property

If a = b then a - c = b - c; Subtraction Property of =

Properties of equality includes; addition, subtraction, transitive, reflexive, and symmetric properties of equality

The transitive property of equality can be stated as follows; If two variables are each equal to a third variable, then the two variables are equal to each other.

Therefore; a = b and b = c then a = c represents the transitive property

The division property states that both sides of an equation remain equal, following a division of both sides by the same non zero number

Therefore;

If a = b then a ÷ c = b ÷ c; represents the division property of equality

The reflexive property of equality states that a measure or number is always equal to itself

Therefore;

a = a represents the reflexive property

Substitution property indicates that if two variables are equal, then one can replace the other in an equation and the results will remain the same

Therefore;

If x + a = b and x = c then c + a = b; represents the substitution property

The statement of the addition (and subtraction) property of equality is that both sides of an equation remain equal following the addition or subtraction of the same amount from both sides the same

Therefore;

If a = b then a + c = b + c; represents the addition property of equality

If a = b then a - c = b - c; represents the subtraction property of equality

This states that both sides of an equation remain equal following the multiplication of both sides by the same value

The symmetric property states that two sides of an equation remain equal when their relative positions are interchanged

This states that two sides of an equation remain equal following a distribution with multiplication over addition or subtraction.

Answer:

y = mx

Step-by-step explanation:

It depends on what form of the line that you want.  Usually the slope intercept form is wanted.

y = mx + b  We need to have the m (slope) and the b (the y-intercept)

The slope is the change in y over the change in x.

Ordered pairs are in the form (x,y)

(0,0) and (4,4)  Have x's of 4 and 0, and y's of 4 and 0.  We subtract these to find the changes in y and x.

[tex]\frac{4-0}{4-0}[/tex]  This is [tex]\frac{4}{4}[/tex] which is the same as 1. The slope (m) is 1.

Now we need to find the y -intercept.  The y intercept is the point where x is 0  (0,b).  They give us this point (0,0,)  So the y -intercept is zero.

y = 1m + 0

or y =mx
