Answer:

(4). g(2) > f(2) False

Step-by-step explanation:

(1). (f(0) = 2) > (g(0) = - 4) (True)

(2). f( - 4) = 4( - 4 ) + 2 = - 14

g( - 4) = (5/2)(- 4) - 4 = = - 14

f( - 4) = g( - 4) (True)

(3). f(6) = 4(6) + 2 = 26

g(12) = (5/2)(12) - 4 = 26

f(6) = g(12) (True)

(4). g(2) = (5/2)(2) - 4 = 1

f(2) = 4(2) + 2 = 10

g(2) > f(2) (False)

Answer:

f(x) -> 2 as x -> -∞ and f(x) -> ∞ as x -> ∞

Step-by-step explanation:

f(x) -> 2 as x -> -∞ and f(x) -> ∞ as x -> ∞

*this is because the graph shows that the y value cannot pass by 2 as the x value constantly decreases and as x is increasing, there is just an arrow showing that the graph is constantly going up and therefore going to ∞

Answer:

250 pages

Step-by-step explanation:

Write an expression for the cost of x pages for each of the companies. Then set the expressions equal, and solve for x, the number of pages.

Quick Copy: 5 + 0.06x

Copy Place: 10 + 0.04x

5 + 0.06x = 10 + 0.04x

0.02x = 5

x = 5/0.02

x = 250

Answer: 250 pages

Check

Quick Copy: 5 + 0.06(250) = 5 + 15 = 20

Copy Place: 10 + 0.04(250) = 10 + 10 = 20

For 250 copies, both places cost $20. 250 copies is the correct answer.

Answer:

a

  [tex]\mu = 6[/tex]

b

  [tex]x= 3.2[/tex]

c

 [tex]P( X> 16 | X > 9 ) = 0.222[/tex]

Step-by-step explanation:

Considering question 1

From the question we are told that  

   The waiting times for the train are known to follow a uniform distribution

i.e  

                [tex]X  \~ \ \ \  Uniform(a =0  , b= 12)[/tex]

Generally the cumulative distribution function for uniform distribution is mathematically represented as

   [tex]F(x) = \left \{ {{0 \ \ \ \ \ \ \\ \ \ \ for x < a } \atop {\frac{x - a}{b-a} \ \ \ \ \ \ for  a \le x \ le b }} \atop { 1 \ \ \ \ \ \ \ \ \ \ \  for  x >  b}\right. [/tex]

Generally the average time is mathematically represented as

       [tex]\mu = \frac{a+ b}{2}[/tex]

=>    [tex]\mu = \frac{0+ 12}{2}[/tex]

=>    [tex]\mu = 6[/tex]

Considering question 2

     The waiting times for the train are known to follow a uniform distribution

i.e  

                [tex]X  \~ \ \ \  Uniform(a =0  , b= 16)[/tex]

Generally the 20th percentile of the waiting time is mathematically represented as

               [tex]f(x) = \frac{x- a }{b- a} = 0.2[/tex]

=>            [tex]f(x) = \frac{x- 0 }{16- 0} = 0.2[/tex]

=>           [tex]x= 3.2[/tex]

Considering question 3

        The waiting times for the train are known to follow a uniform distribution

i.e  

                [tex]X  \~ \ \ \  Uniform(a =0  , b= 18)[/tex]  

Generally the probability of waiting more than 16 minutes given a person has waited more than 9 minutes

       [tex]P( X> 16 | X > 9 ) = \frac{P( X > 16 \ \ n \ \ X > 9 )}{P( X > 9 )}[/tex]

=>     [tex]P( X> 16 | X > 9 ) = \frac{ P(X > 16 )}{P( X > 9 )}[/tex]

=>       [tex]P( X> 16 | X > 9 ) = \frac{\frac{18 - 16}{18} }{\frac{18 - 9}{9 } }[/tex]

=>       [tex]P( X> 16 | X > 9 ) = 0.222[/tex]

The probability shows that the average waiting time is 6 minutes.

The average time will be calculated thus:

= (a + b)/2

= (0 + 12)/2

= 12/2

= 6 minutes

The 20th percentile for the waiting times will be calculated thus:

f(x) = (x - 0)/(16 - 0) = 0.2

x = 0.2 × 16

x = 3.2

Therefore, the 20th percentile for the waiting times is 3.2 minutes.

The probability of waiting more than 16 minutes given a person has waited more than 9 minutes will be calculated thus:

= [(18 - 16)/18] / [(18 - 9)/9]

= 0.222

Answer:

C.

Step-by-step explanation:

I'm assuming that the equation is (1+n) / 7 = 3, where 1+n is the numerator and 7 is the denominator.

In this case, to isolate for n, you have to multiply both sides by 7.

then you get 1+n = 3/7, and then you can get n = 3/7 - 1

Step-by-step explanation:

Answer:

33 7/20

Step-by-step explanation:

First you multiply the number of students performing in the problem (25) to the fraction 3/4 as stated in the problem itself.

25 * 3/4 = 18 3/4

Then you use the answer from the previous step and add it by the expected amount of pound of clay (20)

18 3/4 + 20 = 38 3/4

As from the last step, we use that number and subtract it by the leftover clay (5 2/5)

38 3/4 - 5 2/5 = 33 7/20

33 7/20

Answer:

The value is  [tex]\sigma_{\= x} = 1.789[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  20  

    The sample mean is [tex]\= x = 122.5[/tex]

    The standard deviation is  [tex]s = 8[/tex]

Generally the standard error of the mean is mathematically represented as

       [tex]\sigma_{\= x} = \frac{s}{\sqrt{n} }[/tex]

=>    [tex]\sigma_{\= x} = \frac{8}{\sqrt{20 } }[/tex]

Answer:

30 students

Step-by-step explanation:

Given

[tex]Students = 40[/tex]

[tex]\% = 75\%[/tex] ---- percentage of those that returned their slips

Required

Determine the number of those that returned their slips

Represent the number with n

To calculate n, we simply multiply the number of students by the percentage of those that returned their slips

i.e.

[tex]n = 40 * 75\%[/tex]

Convert % to decimal

[tex]n = 40 * 0.75[/tex]

[tex]n = 30[/tex]

Hence, 30 students returned their slips

Answer:

C

Step-by-step explanation:

The y axis is vertical so you only change the x value.

The coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a triangle shown on the coordinate plane.

If ABC is reflected across the y-axis,

Then the coordinate of C

From the figure, the coordinate of C is(before reflection)

C = (6, 3)

The rule for transformation if reflected across the y-axis:

(x, y) → (-x, y)

(6, 3) → (-6, 3)

Thus, the coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.
