The value of the expression m • s will be 10 after evaluating it for m = 2 and s = 5.

We are given an expression:

m • s

We need to evaluate the expression for m = 2 and s = 5

So, after substituting the values in the expression, we get that:

m • s

= ( 2 ) • ( 5 )

Multiplying the values, we get that:

= 10

Therefore, the value of the expression m • s will be 10 after evaluating it for m = 2 and s = 5.

Step-by-step explanation:

Answer:

  m = -4

Step-by-step explanation:

You want the solution to the "two step" equation m -4 = 2m.

A "two-step" linear equation is one that can be solved in two steps. The steps in general are ...

The "inverse" properties of addition and multiplication are used to identify the quantities added or multiplied.

There are two forms a two-step equation might take:

  ax +b = c

  ax +b = cx

You will notice that one side of the equal sign has a sum of two terms: a term with the variable, and a constant term without the variable. The other side of the equation will have one term, which may be either a constant term or a variable term.

The idea of the first step is to make sure the variable term ends up on one side of the equal sign, and the constant term ends up on the other side.

The parts of the first step are ...

For the given equation ...

  m - 4 = 2m

The term by itself is a variable term. The variable term on the other side of the equation is "m". The first step will be to add "-m" to both sides of the equation.

  m -4 -m = 2m -m . . . . . . -m added to both sides

  -4 = m . . . . . . . . . . . . . simplify

Now, we have a variable term (m) on one side of the equal sign, and a constant term (-4) on the other side. This is the desired result of the first step.

The idea of the second step is to make the coefficient of the variable be 1. We do that by multiplying both sides of the equation by the reciprocal (inverse) of the coefficient of the variable.

For the equation ...

  ax = b

we multiply by the reciprocal of 'a', which is 1/a.

  (ax)(1/a) = b(1/a)

  x = b/a . . . . . . . . . . . effectively, we're dividing by 'a'

In the given equation, we have ...

  -4 = m

which already has a coefficient of 1 on the variable m. This means we're done, and no additional step is actually needed.

The solution is m = -4.

__

Additional comment

There is another form of 2-step equation you may see occasionally:

  a(x +b) = c

Solving this can be done by reversing the order of the steps: first divide by the coefficient of x, then subtract the constant.

  x +b = c/a

  x = (c/a) -b

If the variable term inside parentheses has a coefficient other than 1, it may be useful to eliminate parentheses using the distributive property, then solve like a regular 2-step equation.

Answer:

The answer is 5

Step-by-step explanation:

From every side

By evaluating the functions we get:

Here we have the two functions:

f(x) = -2x - 5

g(x)= 3x^2 - 3x - 13

And we want to evaluate them in some values of x, first let's do the ones for f(x).

We just replace the variable x by the numbers.

f(3)= -2*3 - 5 = -10 - 5 = -15

f(-2) = -2*(-2) - 5 = 4 - 5 = -1

The ones for the function g(x) are:

g(4) = 3*4^2 -3*4 -13 = 23

g(-5) = 3*(-5)^2 - 3*(-5) - 13 = 77

g(a) = 3*a^2 - 3*a - 13

Using the normal distribution, the percentages are given as follows:

a) 9.18%.

b) 97.72%.

c) 50%.

d) 4.27%.

e) 0.13%.

f) 59.29%.

g) 2.46%.

h) 50%.

i) 50%.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For this problem, the mean and the standard deviation are given as follows:

[tex]\mu = 247, \sigma = 60[/tex]

For item a, the proportion is the p-value of Z when Z = 167, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (167 - 247)/60

Z = -1.33.

Z = -1.33 has a p-value of 0.0918.

Hence the percentage is of 9.18%.

For item b, the proportion is the p-value of Z when Z = 367, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (367 - 247)/60

Z = 2.

Z = 2 has a p-value of 0.9772.

Hence the percentage is of 97.72%.

For item c, the proportion is one subtracted by the p-value of Z when X = 247, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (247 - 247)/60

Z = 0

Z = 0 has a p-value of 0.5.

Hence the percentage is of 50%.

For item d, the proportion is one subtracted by the p-value of Z when X = 350, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (350 - 247)/60

Z = 1.72

Z = 1.72 has a p-value of 0.9573.

1 - 0.9573 = 0.0427.

Hence the percentage is of 4.27%.

For item e, the proportion is the p-value of Z when Z = 67, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (67 - 247)/60

Z = -3.

Z = -3 has a p-value of 0.0013.

Hence the percentage is of 0.13%.

For item f, the proportion is the p-value of Z when X = 300 subtracted by the p-value of Z when X = 200, hence:

X = 300:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (300 - 247)/60

Z = 0.88.

Z = 0.88 has a p-value of 0.8106.

X = 200:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (200 - 247)/60

Z = -0.78.

Z = -0.78 has a p-value of 0.2177.

0.8106 - 0.2177 = 0.5929.

Hence the percentage is 59.29%.

For item g, the proportion is the p-value of Z when X = 400 subtracted by the p-value of Z when X = 360, hence:

X = 400:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (400 - 247)/60

Z = 2.55.

Z = 2.55 has a p-value of 0.9946.

X = 360:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (360 - 247)/60

Z = 1.88.

Z = 1.88 has a p-value of 0.97.

0.9946 - 0.97 = 0.0246

Hence the percentage is 2.46%.

For items h and i, the distribution is symmetric, hence median = mean and the percentages are of 50%.

Step-by-step explanation:

The m∠POS would be - 65° by the angle addition postulate and substitution postulate.

Given, m∠POQ = 19° , m∠QOR = 31° and m∠ROS = 15°

Angle Addition Postulate is the measure of the larger angle is the sum of the measures of the two smaller angles.

Substitution postulate states that a quantity may be substituted for its equality in any expression.

Then substitute the angle  measurements into the resulting equation to find, m∠POS:

m∠POQ + m∠QOR = m∠POR (by angle addition)

m∠POR + m∠ROS = m∠POS (by substitution)

m∠POS = m∠POQ + m∠QOR + m∠ROS

= 19° + 31° + 15°

= 65°

Thus, the m∠POS would be - 65° by the angle addition postulate and substitution postulate.

The speed of the second pedestrian is 5 kilometers per hour.

Let's say that the speed of the second pedestrian is S.

We know that the other pedestrian walks at a speed of 4km/h, and they (together) travel a distance of 27km in 3 hours, then we can write the linear equation:

(4km/h + S)*3h = 27km

It says that both pedestrians work, together, a total of 27km in 3 hours.

Now we can solve that linear equation for S, to do this, we need to isolate S in the left side of the equation.

4km/h + S = 27km/3h = 9 km/h

S = 9km/h - 4km/h = 5km/h

The linear function c(x) to represent the cost of tuition as a function of "the number of years since 1990" denoted by "x" is [tex][c(x) = 14x+94][/tex].

As per the question statement, the cost of tuition at a large Midwestern university was $94 per credit hour in 1994 while it had risen to $290 per credit hour in 2004.

We are required to determine a linear function c(x) that represents the cost of tuition as a function of "the number of years since 1990", denoted by "x".

To solve this question, we need to know the equation of a line passing through two points (x₁, y₁) and (x₂, y₂) which goes as

[tex](y-y_{1} )=(\frac{y_{2} -y_{1} }{x_{2} -x_{1}})(x-x_{1})[/tex].

Here, if we consider (x = 0) at 1990, c(x) = 94.

And since the standard form of conversion of functions into coordinate points goes as [y = f(x)], i.e., the ordinate is a function of the abscissa, therefore in this case, [y = c(x) = 94].

Thus, we can consider (x₁, y₁) as (0, 94).

Similarly, at 2004, [x = (2004-1990) = 14], and c(x) = 290, i.e.,

We can consider as (x₂, y₂) as (14, 290).

Using the values of (x₁, y₁) and (x₂, y₂), in the above mentioned standard equation of line passing through two points, we get,

[tex](y-94)=\frac{290-94}{14-0} (x-0)\\or, (y-94)=\frac{196}{14}x\\or,(y-94)=14x\\or,y=14x+94[/tex].

Hence, the linear function c(x) that represents the cost of tuition as a function of "the number of years since 1990", denoted by "x" is  [tex][c(x) = 14x+94][/tex].

Add the lengths of the triangle's sides to find its perimeter. For instance, if a triangle comprises sides a, b, as well as c, the perimeter of the that triangle is P = a + b + c.

2D objects have two dimensions, for example, width and height. A rectangle or even a circle are two-dimensional shapes. Because they have without depth, 2D forms are absolutely flat and can not be physically handled.

Points of the tringles:

A (−3,−1),

B (1,−1),

C (1,2)

we know that the:

Perimeter of the triangle = sum of all the side of the triangle

                                         = AB + BC + CA

So

Length of the AB  :

A (−3,−1),

B (1,−1),

AB =√((x2 – x1)² + (y2 – y1)²).

AB =  √((1 – (-3))² + (-1 – (-1))²).

AB = √((4) + (0))

     = √(16)

     = 4

Length of the BC :

B (1,−1),

C (1,2)

BC =√((x2 – x1)² + (y2 – y1)²).

BC =√((1 – 1)² + (2 – (-1))²).

BC =√(0)² + (3)²).

BC = √(9)

    = 3

Length of the CA:

A (−3,−1),

C (1,2)

CA =√((x2 – x1)² + (y2 – y1)²).

CA =√((1 – (-3))² + (2 – (-1))²).

CA =√((4))² + (3)²).

CA =√(16 + 9)

CA =√(25)

      = 5

The perimeter of the triangle asked  = AB + BC + CA

                                                            = 4 + 3 + 5
