Answer

a = 200 + 0.5 (200) = $210

Step-by-step explanation:

use

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

slope is

[tex]m = \frac{ y_{2} - y_{1}}{x_{2} - x_{1}} \\[/tex]

[tex]if \: \: m_{1} = m_{2} \: \: lines \: are \: parallel \\ [/tex]

[tex]if\:m_{1} = - \frac{1}{m_{2}} \\ lines \: are \: perpendicular \: to \: each \: other[/tex]

Parallel lines have the same slope

The slope of a line is calculated as:

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

The slope of line 1 is:

[tex]\mathbf{m_1 = \frac{9 - 5}{-8 - 10}}[/tex]

[tex]\mathbf{m_1 = \frac{4}{-18}}[/tex]

[tex]\mathbf{m_1 = -\frac{2}{9}}[/tex]

Hence, the slope of line 1 is -2/9

The slope of line 2 is:

[tex]\mathbf{m_2 = \frac{-6 - -4}{11 - 2}}[/tex]

[tex]\mathbf{m_2 = \frac{-2}{9}}[/tex]

[tex]\mathbf{m_2 = -\frac{2}{9}}[/tex]

Hence, the slope of line 2 is -2/9

The lines have the same slope.

Hence, the two lines are parallel

Answer:

just remember that each baby elephant weight 3/8 of a ton

and all together weight 3/4 of a ton

so how many baby elephants will be ,let be x a unknown number of them

so

x*(3/8) =3/4

because multiplying the number of baby elephants with their body weight gives the total weight of all baby elephants.

so

x=(3/4)*(8/4)=2

the number of baby elephants is 2

Answer:

Undefined

Step-by-step explanation:

The x value is always 5 so the slope is undefined

Answer:

The slope of the line is undefined.

Step-by-step explanation:

To solve this problem, we should use the formula for slope, which is given below:

m = slope = (y2-y1)/(x2-x1)

If we plug in two of the points that are given in the table, we get:

m = slope = (6-3)/(5-5)

If we perform the subtraction in the parentheses in both the numerator and the denominator, we get:

slope = 3/0

Since we cannot divide by 0, this means the slope is undefined.

Answer:

a) P(A) = 0,4607     or   P(A) = 46,07 %

b) P(B) = 0,7120   or 71,2 %

c) P(C) = 0,2055  or P(C) = 20,55 %

Step-by-step explanation:

We will use two concepts in solving this problem.

1.- The probability of an event (A) is for definition:

P(A) = Number of favorable events/ Total number of events FE/TE

2.- If A and B are complementary events ( the sum of them is equal to 1) then:

P(A) = 1 - P(B)

a) The total number of events is:

C ( 24,4) = 24! / 4! ( 24 - 4 )!    ⇒  C ( 24,4) = 24! / 4! * 20!

C ( 24,4) = 24*23*22*21*20! / 4! * 20!  

C ( 24,4) = 24*23*22*21/4*3*2

C ( 24,4) = 24*23*22*21/4*3*2    ⇒  C ( 24,4) =  10626

TE = 10626

Splitting the group of tanks in two 6 with h-v  and 24-6 (18) without h-v

we get that total number of favorable events is the product of:

FE = 6* C ( 18, 3)  = 6 * 18! / 3!*15!  =  18*17*16*15!/15!

FE =  4896

Then P(A) ( 1 tank in the sample contains h-v material is:

P(A) = 4896/10626

P(A) = 0,4607     or   P(A) = 46,07 %

b) P(B) will be the probability of at least 1 tank contains h-v

P(B) = 1 - P ( no one tank with h-v)

Again Total number of events is 10626

The total number of favorable events for the ocurrence of P is C (18,4)

FE = C (18,4) = 18! / 14!*4! = 18*17*16*15*14!/14!*4!

FE = 18*17*16*15/4*3*2  = 3060

Then P = 3060/10626

P = 0,2879

And the probability we are looking for is

P(B) = 1 - 0,2879

P(B) = 0,7120   or 71,2 %

c) We call P(C) the probability of finding exactly 1 tank with h-v and t-i

having 4 with t-i tanks is:

reasoning the same way but now having 4 with t-i (impurities) number of favorable events is:

FE = 6*4* C(14,2) = 24 * 14!/12!*2!

FE = 24* 14*13*12! / 12!*2

FE = 24*14*13/2    ⇒  FE = 2184

And again as the TE = 10626

P(C) = 2184/ 10626

P(C) = 0,2055  or P(C) = 20,55 %

Answer: Orange.

Step-by-step explanation:

The graph of the slopes of the red function is equal to the derivate of the red function.

First, let's analyze the red function (from left to right).

First we can see that the red function is positive, and it decreases (so we must have a negative slope here).

Then we can see a little inflection point where the red function seems to be constant for a bit (here the slope must become zero for a little bit).

Then the red function keeps decreasing (so the slope is negative again).

Then the graph of the slope is:

Negative, then it increases to zero, and it decreases again.

The only graph that does this is the orange one, so the answer is orange.

Answer:

y = 5/4x + 9

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define

m = 5/4

Random point (-8, -1)

y = 5/4x + b

Step 2: Find y-intercept b

-1 = 5/4(-8) + b

-1 = -10 + b

b = 9

Step 3: Write linear equation

y = 5/4x + 9
