Step-by-step explanation:

235-75 one time fee, so subtract = 160

160/40 = 4

Answer:

4 Hours

40x - 75 = 235

         -75    -75

40x  = 160

40x/40 = 160/40

x = 4

Step-by-step explanation:

Hey there!

Let the unknown slope be M2.

The given equation is;

15x + 12y = -144

From equation;

[tex]slope( m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]

[tex]m = \frac{ - 15}{12} [/tex]

[tex]m = \frac{ - 5}{4} [/tex]

For the condition of perpendicular lines;

[tex]m \times m2 = - 1[/tex]

[tex] \frac{ - 5}{4} \times m2 = - 1[/tex]

[tex] - 5m2 = - 4[/tex]

[tex]m2 = \frac{ - 4}{ - 5} [/tex]

Therefore, the slope is 4/5.

Hope it helps....

Answer:

85 messages

Step-by-step explanation:

The system of equations for this is

35 + .10x

18 + .3x

where x = the number of text messages

Usually, you would use substitution or elimination to solve this problem. However, because the answer choices were given, you can just plug in the values.

When you plug in 85, or x = 85, you get 43.5 for both equations because

35 + .10(85) = 43.5     18 + .3(85) = 43.5

Therefore, the answer would be 85 messages becuase both plans will cost the same when you send 85 text messages!

Answer:

First even integer: 6

Step-by-step explanation:

Inequalities

Assume x is the first even integer. The next integer is x+2, and the last integer ix x+4.

The condition states that the sum of the first and the second number is 15 less than three times the third. This takes us to the inequality:

[tex]x+x+2<3(x+4)-15[/tex]

Operating:

[tex]2x+2<3x+12-15[/tex]

Subtracting 2 and 2x:

[tex]0<3x+12-15-2x-2[/tex]

Simplifying:

[tex]0<x-5[/tex]

Solving:

x>5

There are infinitely many solutions. For example, for x=6 (first even number into the solution interval):

First integer: 6

Second integer: 8

Third integer: 10

There are other solutions, like 20,22,24 but the first set is 6,8,10.

Step-by-step explanation:  The prime factorization of  4320   is

  2•2•2•2•2•3•3•3•5  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 4320   =  √ 2•2•2•2•2•3•3•3•5   =2•2•3•√ 30   =

               ±  12 • √ 30

 √ 30   , rounded to 4 decimal digits, is   5.4772

So now we are looking at:

          w  =  ( -40 ± 12 •  5.477 ) / -34

Two real solutions:

w =(-40+√4320)/-34=(20-6√ 30 )/17= -0.757

or:

w =(-40-√4320)/-34=(20+6√ 30 )/17= 3.110

Answer:

We have to find the equation of the red line

To get the equation of the line in the slope-intercept form,

we need its slope and its y-intercept

Finding the Slope

we know that the slope of a line is the rise of the line / run of the line between 2 points

here, the 2 points are already marked on the graph

So, slope = rise / run

we notice that the line rises only 2 units and runs 8 units between the points: (-5 , 3 ) and (3 , 5)

Slope = rise  / run

now that we know the values of rise and run, we can plug the values to get the slope

Slope  = 2 / 8

Slope = 1 / 4

Finding the y-intercept

We will now look at the point (-5 , 3) , we know that the slope is 1/4.

which means that every time the line moves 1 unit to the right, it also moves 1/4 units up

So, until the point (-1 , 4), the line has finally ascended 1 unit and now is at a proper coordinate

We can see that the line is only 1 unit to the left of the y-axis, so the y-coordinate of the line after moving 1 unit to the right is the y-intercept

since the line ascends 1/4 units every time it moves 1 unit to the right,

the ordinate of the line at the y-axis will be 1/4 more than the last ordinate (which was 4)

y-intercept = (4 + 1/4)

y-intercept = 17 / 4

Equation of the line

From the question, we know that the general form of the slope-intercept form is :

y  = mx + b (where m is the slope and b is the y-intercept)

y = (1/4)x + (14/4)

y = (x + 14) / 4

Answer:

a)  P(X>=1) = 0,7293        or   P(X>=1) =  72,93 %

b)  P(X>=3) = 0,5686     or     P(X>=3) = 56,86 %

c)  y =  0,8494 mm³

d) λ = 1,69897 inc per mm³

Step-by-step explanation:

a) P(X>=1) = 1 - P(X=0)

P(X = 0) = λ⁰ * e∧⁻λ / 0!          where λ  = 2 in/mm³

P(X = 0) = e∧-2    ⇒    P(X = 0) = 0,2706

Then

P(X>=1) = 1 - 0,2706

P(X>=1) = 0,7293        or   P(X>=1) =  72,93 %

b) 3 inc. in 4 mm³ = 2*4/3     λ = 2,67 inc. per mm³

P(X>=3)  =  1 - P(X=1 ) - P(X=2)

P(X=1) = λ¹ * e∧-λ / 1!    ⇒  P(X=1) = 2,67 *e∧- 2,67/1

P(X=1) = 0,1846

P(X=2) = λ² * e∧-λ / 2!   ⇒   P(X=2) = (2,67)² * e ∧ - 2,67/2

P(X=2) = 7,1289* 0,06925/2     ⇒  P(X=2) = 0,2468

Then

P(X>=3)  =  1 -  0,1846 - 0,2468

P(X>=3) = 0,5686     or     P(X>=3) = 56,86 %

c) P(X>=1) = 0,98

and λ = 2*y     where y is the quantity of material

P(X=0) = 1 -  P(X>=1)

P(X=0) = 1 - 0,98    P(X=0) = 0,02

0,02 = (2*y)⁰  * e ∧ -2*y /0!

0,02 = 1 *  e ∧ -2*y

Taking log on both sides of the equation

log (0,02) = -2*y        - 1,69897 = - 2*y

y =  0,8494 mm³

d) P(X  >=1 ) = 1 - P( X = 0)

0,98 = 1 - P( X = 0)

P( X = 0) = 0,02

0,02 = λ⁰ * e ∧ - λ / 0!

0,02 = e ∧ -λ

Taking log on both sides of the equation we get:

log ( 0,02 ) = - λ

- 1,69897  =  - λ

λ = 1,69897  inc. per mm³

Answer:

Step-by-step explanation:

to get the GCF of 24 and 12

you have to factor each value, then choose all the copies of

factor and times or multiply them.

so,

  24 = 2 2 2 3

   12 =  2 2    3

GCF =  2  2    3

therefore, the GCF is 2 x 2 x 3 = 12

hope it helps. good luck!

Answer:

Step-by-step explanation:

opposite angles are equal

12x - 18 = 8x + 10

combine similar terms:

12x - 8x = 10 + 18

4x = 28

x = 28/4

x = 7

plugin the value of x=7 back into the equation to solve the angle

= 12x - 18

= 12(7) - 18

= 66

= 8x + 10

= 8(7) + 10

= 66

Answer:

Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis

Step-by-step explanation:

Sample proportion = p= 531/648 = 0.8194

This is the proportion of men that were hit by lightening

Null hypothesis: H0: p = 0.5

Alternate hypothesis: H1: p ≠ 0.5

Test statistics z = 0.8194-0.5/(√0.5x0.5/648)

= 0.8194-0.5/√0.0003858

= 0.3194/0.019642

= 16.26

Since the z > 1.96 (at 5% significance) we reject the null hypothesis.

Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.

Answer:

5.3

Step-by-step explanation:

1.8x = 9.4

x = 5.3

The value of x that makes the equation true is 5.3, the correct option is D.

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equation is,

0.3x + 5. 14 = 2.1x - 4.4

The equation is made of two expressions,

The expression 1 is : 0.3x + 5. 14

The expression 2 is : 2.1x - 4.4

The value of x that makes the equation true has to be determined.

0.3x + 5. 14 = 2.1x - 4.4

Grouping the like terms on one side.

5.14 +4.4 = 2.1x -0.3x

Solving the variables and constants

9.54 = 1.8 x

Dividing 1.8 on both sides of the equation.

x = 9.54 /1.8

x = 5.3

The value of x at which the equation is true is 5.3.

Answer:

No, because one x-value corresponds to two different y-values ⇒ D

Step-by-step explanation:

The relation of x and y can be a function if every x has only one value of y (x not repeated)

Examples:

Let us check the given table

∵ At x = 2, y = 1

∵ At x = 3, y = 4

∵ At x = 4, y = 4

∵ At x = 5, y = 2

∵ At x = 5, y = 5

∵ x = 5 has two values of y 2 and 5

→ That means x is repeated

∴ Not every x has only one value of y

∴ The table does not represent a function
