Which Function Could Produce The Graph Shown Below?dnesda-4+3+25101520253035

Answers

Answer 1

  Exponential function given in Option (C). f(x) = 4e⁻⁰°⁰⁵ will be the answer.

Exponential function:  An exponential function is given by,

          [tex]f(x)=ae^{bx}[/tex]

Given in the question,

 Graph of the exponential function passes through two points,

          (0, 4) and (27.5, 1)

For (0, 4),

[tex]4=ae^{b\times 0}[/tex]

[tex]a=4[/tex]

For (27.5, 1)

[tex]1=4(e)^{27.5\times b}[/tex]

[tex]e^{27.5b}=0.25[/tex]

[tex]\text{ln}e^{27.5b}=\text{ln}(0.25)[/tex]

27.5b = -1.3863

b = -0.05

     Therefore, exponential function will be → [tex]f(x)=4e^{-0.05x}[/tex]

                       Option (C) will be the answer.

Find the value of x.
Pleaseeee I needddd helpppp!!!!!!

Answers

Answer:

x = 40

Step-by-step explanation:

Measure of an external angle of a circle = ½(difference of the intercepted arcs)

This means that:

½(PQ - RS) = m<T

m<T = x/2

PQ = (x + 70)°

RS = (x + 30)°

Plug in the values

½((x + 70) - (x + 30)) = x/2

½(x + 70 - x - 30) = x/2

½(x - x + 70 - 30) = x/2

½(0 + 40) = x/2

½(40) = x/2

20 = x/2

Multiply both sides by 2

20*2 = x

40 = x

x = 40

y=3/2x-9
I need to find the x-intercept and the y-intercept with work plsss

Answers

Hi there!

x-int: (6, 0)

y-int: (0, -9)

y = 3/2x - 9

Begin by finding the x-intercept. The x-intercept is located where y = 0, therefore:

0 = 3/2x - 9

Isolate for x by adding 9 to both sides:

9 = 3/2x

Divide both sides by 3/2x:

9 * 2/3 = x

x = 6. Thus, the x-intercept is at (6, 0).

Find the y-intercept by finding the y-value at which x = 0:

y = 3/2(0) - 9

y = -9. The y-intercept is at (0, -9).

Count how many numbers you have, 11.

11 is an odd number so, the number in the middle of the data set is the median.

Final answer: $7.99 is the median.

What is equivalent to 0 = 2x2 - 16x – 18 when completing the
square?

Answers

Answer:

x = 1

x = -9

Step-by-step explanation:

(2x2 +  16x) -  18  = 0

2x2 + 16x - 18  =   2 • (x2 + 8x - 9)

x2 + 8x - 9

 -9    +    1    =    -8

     -3    +    3    =    0

     -1    +    9    =    8

 2 • (x + 9) • (x - 1)  = 0

2   =  0

x+9 = 0  

x = -9

x-1 = 0

x = 1

x2 + 8x - 9  = 0

  x2+8x = 9

(x+4) • (x+4)  =

 (x+4)2

x2+8x+16 = 25 and

  x2+8x+16 = (x+4)2

(x+4)2 = 25

x = -4 + √ 25

 x2 + 8x - 9 = 0

has two solutions:

 x = -4 + √ 25

  or

 x = -4 - √ 25

           

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

A   =     1

                     B   =    8

                     C   =   -9

B2  -  4AC   =

                    64 - (-36) =

                    100

 -8 ± √ 100

  x  =    —————

                   2

  x  =  ( -8 ± 10) / 2

x =(-8+√100)/2=-4+5= 1.000

or:

x =(-8-√100)/2=-4-5= -9.000

A paint manufacturer wants to determine the average drying time of a new interior wall paint. For n = 50 test areas of equal size he obtained a sample mean drying time of ¯x = 63.3 minutes and a sample standard deviation of s = 8.4 minutes. (a) (5 points) Construct the 95% confidence interval for the true mean µ. (b) (5 points) Suppose the population has a normal distribution, construct the exactly 95% confidence interval for the true mean µ. (c) (5 points) Suppose the population has a normal distribution, construct the 95% prediction interval for a new observation.

Answers

Answer:

a) the 95% confidence interval for the true mean µ is 60.971, 65.629

The exact 95% confidence interval for the true mean µ is 60.971, 65.629

P (x`- ∝ s/√n<u <x`+ ∝ s/√n) = 0.95

Step-by-step explanation:

n= 50

x`= 63.3

s= 8.4 minutes

∝= 95%= ±1.96

The formula for calculating the confidence interval is:

x`± ∝ s/√n

Putting the values

x`± 1.96 s/√n

63.3 ± 1.96(8.4/√50)

63.3± 2.3287

60.971, 65.629

a) the 95% confidence interval for the true mean µ is 60.971, 65.629

b) Putting the values

x`± 1.96 s/√n

63.3 ± 1.96(8.4/√50)

63.3± 2.3287

The exact 95% confidence interval for the true mean µ is 60.971, 65.629

c) The prediction level tells that the drying time of the wall from 60.971 to 65.629 minutes must be in the range 95 % of the time.

And is given by

P (x`- ∝ s/√n<u <x`+ ∝ s/√n) = 0.95
