[tex]P(X > 7) = 0.5[/tex]

b

[tex]P(X < 3) = -0.5[/tex]

c

[tex]x = 6.2 \ hours[/tex]

d

[tex]x_1 = 8 \ hours[/tex]

e

Mean [tex]\mu = 7[/tex]

Standard deviation [tex]s \approx 1.1547[/tex]  

Step-by-step explanation:

From the question we are told that

  The amount of time a repairman needs to fix a furnace is uniformly distributed from 5 and 9 hours

Generally the probability that it takes the repairman more than 7 hours to fix a furnace is mathematically represented as

     [tex]P(X > 7) = \frac{9- 7}{9-5}[/tex]

=>[tex]P(X > 7) = 0.5[/tex]

Generally the probability that a randomly selected furnace repair requires less than 3 hours. is mathematically represented as

     [tex]P(X < 3) = \frac{3 -5}{9-5}[/tex]

=>[tex]P(X < 3) = -0.5[/tex]

Generally the 30th percentile of furnace repair times is mathematically represented as

     [tex]30^{th} \ percentile = \frac{x - 5}{9-5}[/tex]

=>  [tex]0.3 = \frac{x - 5}{9-5}[/tex]

=>  [tex]x = 6.2 \ hours[/tex]

Generally the time taken for the longest 25% of furnace repair is mathematically evaluated as

  [tex]75^{th} \ percentile = \frac{x_1 - 5}{9-5}[/tex]

Here making use of the [tex]75^{th}[/tex] because we are considering duration that fall with the top [tex]25^{th}[/tex]

=> [tex]0.75 = \frac{x_1 - 5}{9-5}[/tex]

=> [tex]x_1 = 8 \ hours[/tex]

Generally the mean is mathematically represented as

          [tex]\mu = \frac{5 + 9 }{2}[/tex]

=>        [tex]\mu = 7[/tex]

Generally the standard deviation is mathematically represented as

     [tex]s = \sqrt{ \frac{(9- 5)^2}{12} }[/tex]  

=>   [tex]s \approx 1.1547[/tex]

Step-by-step explanation:

3.Each day you exercise you either walk 5 miles or jog 2 miles. You exercised 19 days last month and the total distance you travelled was 74 miles. How many days did you walk?

Answers

Answer:

You walk 12 days

Step-by-step explanation:

Let's call:

W=Number of days you walk

J=Number of days you jog

Since you only do one of the exercises per day:

W + J = 19

Solving for J:

J = 19 - W

Every day you walk, you travel 5 miles, and every day you jog, you travel 2 miles, thus:

5W + 2J = 74

Replacing the expression for J:

5W + 2(19 - W) = 74

Operating:

5W + 38 - 2W = 74

Simplifying:

3W = 74 - 38 = 36

Solving:

W = 36 / 3 = 12

You walk 12 days

O (11,44)

O (4,44)

O (4,15)

Help

Answers

Answer:

Point of the flower garden  R ( 11, 44 )

Step-by-step explanation:

Let´s call   P (  3, 14 ) The center of the herb garden, and Q ( 7 , 29 ) the birdbath point

Differences in coordinates of these two points are:

x axis        7 - 3   = 4

y axis     29 - 14  = 15

Then the point Q ( x , y ) will be at:  Q ( 11, 44)

x axis    x = 11 because    7 + 4 = 11 means that the coordinate 7 is just halfway way between coordinates (x)  3 and 11  ( 4 above 3, and 4 below 11)

Reasoning the same way we conclude y = 44 in this case 29 is just halfway between coordinates  (y) 14 and 44 ( 15 above 14 and 15 below 44)

We can probe getting distance d₁  between P and Q  and d₂ distance between Q and R as:

d₁ = √ (7-3)² + ( 29-14)²

d₁ = √ 16 + 225

d₂ = √ (11 - 7)² +  ( 44 - 29)²

d₂ = √ 16 + 225

charges $35. If your dog is between 15 and 40 pounds, she charges $40. If your dog is over 40 pounds, she charges $40,
plus an additional $2 for each pound.
a. Write a piecewise function that describes what your dog groomer charges.
b. Graph the function.

Answers

Answer:

hope the pics below helps!!

Plz mark brainliest :DD

The groomer charges is an illustration of a piece-wise function, where different functions are used to handle different inputs.

The piece-wise function is:

[tex]f(x) = \left[\begin{array}{ccc}35,&x \le 15\\40, &15 < x \le 40\\2x - 40,&x > 40\end{array}\right[/tex]

Let:

[tex]x \to[/tex] weight of dog

[tex]y \to[/tex] charges

Dogs that weigh 15 pounds or under

This means that: [tex]x \le 15[/tex]

And the charges is [tex]y = 35[/tex]

Dogs that weigh between 15 and 40 pounds

This means that: [tex]15 < x \le 40[/tex]

And the charges is [tex]y = 40[/tex]

Dogs that weigh over 40 pounds

This means that: [tex]x > 40[/tex]

And the charges is [tex]y = 40 + (x - 40) \times 2[/tex]

Simplify

[tex]y = 40 + 2x - 80[/tex]

Collect like terms

[tex]y = 2x +40- 80[/tex]

[tex]y = 2x - 40[/tex]

So, the piece-wise function is:

[tex]f(x) = \left[\begin{array}{ccc}35,&x \le 15\\40, &15 < x \le 40\\2x - 40,&x > 40\end{array}\right[/tex]

The US Department of Health and Human Services wants to know whether the national healthcare system is achieving its goals in Florida. Much information about healthcare comes from

patient records, but that source doesn't allow us to compare people who use health services with those who don't. Therefore, the US Department of Health and Human Services conducted the

Florida Health Survey, which was used to interview a random sample of 62,348 people who live in the state of Florida.

Part A: What is the population for this sample survey? What is the sample? (4 points)

Part B: The survey found that 74% of males and 83% of females in the sample had visited a general practitioner at least once during the past year. Do you think these estimates are close to

the truth about the entire population? Explain. (6 points) (10 points)

Answers

Answer:

A)i) Population: Total number of people that reside in Florida..

II) Sample: 62348 people that took part in the random survey.

B) No, the estimates are not close to the truth of the entire population.

Step-by-step explanation:

A)i) The population is the total number of people that reside in Florida.

II) The sample is the 62348 people that took part in the random survey.

B) From the details given in the question, we will see that people who are not part of the healthcare system weren't included due to the fact that they used patients records to judge. This means that if they don't have healthcare, then they will have no patient records. Therefore, we can conclude that the estimates are not close to the truth of the entire population due to the fact that that those who weren't part of the Healthcare system were not considered.

Answers

Answer:

a) mean = 0.2

variance = 0.0391

standard deviation = 0.198

b) The average hurricane is aprox. category 2.*  (B)

Step-by-step explanation:

In order to find the mean, variance, and standard deviation, let us for a table for the data:

level            x

1             0.411

2            0.278

3            0.221

4            0.080

5            0.010

Calculating the mean ([tex]\bar{x}[/tex])

[tex]\bar{x} = \frac{x_1+x_2+x_3+x_4 + x_5}{n}\\\\\bar{x} = \frac{0.411 + 0.278 + 0.221 + 0.080 + 0.010}{5}\\\bar{x} = \frac{1}{5}\\ \bar{x} = 0.2[/tex]

∴Mean = 0.2

level            x         [tex]x- \bar{x}[/tex]         [tex](x - \bar{x})^2[/tex]  

1             0.411         0.211         0.0445  

2            0.278       0.078        0.0608

3            0.221        0.021         0.000441    

4            0.080        -0.12         0.0144

5            0.010         -0.19         0.0361

                                              [tex]\sum(x - \bar{x})^2 = 0.1562[/tex]

[tex]variance = \frac{\sum(x - \bar{x})^2}{n-1} \\variance = \frac{0.1562}{4} \\variance = 0.0391[/tex]

standard deviation = √(variance)

Standard deviation = √(0.0391)

Standard deviation = 0.198

Answer:

A. [tex]C(x,y) = (3,-1)[/tex], [tex]r = 2[/tex], x-Intercepts: [tex]x = 3\pm\sqrt{3}[/tex], y-Intercepts: none.

Step-by-step explanation:

Let [tex]x^{2}+y^{2}-6\cdot x + 2\cdot y + 6 = 0[/tex] be the general equation of the circle, we must transform the expression into standard form to determine its center, radius and intercepts. The procedure is shown below:

1)  [tex]x^{2}+y^{2}-6\cdot x + 2\cdot y + 6 = 0[/tex] Given.

2) [tex](x^{2}-6\cdot x)+(y^{2}+2\cdot y) +6= 0[/tex] Commutative and associative properties.

3) [tex](x^{2}-6\cdot x)+(y^{2}+2\cdot y) + 6 + 3 + 1 = 3 + 1[/tex] Compatibility with addition.

4) [tex](x^{2}-6\cdot x +9)+(y^{2}+2\cdot y +1) = 4[/tex] Definition of addition/Commutative and associative properties.

5) [tex](x-3)^{2} + (y+1)^{2} = 4[/tex] Perfect square trinomial/Result.

The equation of the circle centered in (h, k) in standard form is defined as:

[tex](x -h)^{2} + (y-k)^{2} = r^{2}[/tex] (Eq. 1)

Where:

[tex]h[/tex], [tex]k[/tex] - Coordinate of the center of the circle, dimensionless.

[tex]r[/tex] - Radius of the circle, dimensionless.

By direct comparison we find that circle is centered in [tex]C(x, y) = (3, -1)[/tex] and has a radius of 2.

Finally, we obtain the intercepts of the given function:

x-Intercepts ([tex]y = 0[/tex])

[tex](x-3)^{2} + (0+1)^{2} = 4[/tex]

[tex]x^{2}-6\cdot x +9+1 = 4[/tex]

[tex]x^{2}-6\cdot x +6=0[/tex]

Roots are found analitically by Quadratic Formula:

[tex]x = 3\pm\sqrt{3}[/tex]

y-Intercepts ([tex]x=0[/tex])

[tex](0-3)^{2}+(y+1)^{2} = 4[/tex]

[tex]9+y^{2}+2\cdot y +1 = 4[/tex]

[tex]y^{2}+2\cdot y +6 = 0[/tex]

Roots are found analitically by Quadratic Formula:

[tex]y = -1\pm i\,\sqrt{5}[/tex]

In a nutshell, there are no y-Intercepts.

We include a graphic including circle, center and x-Intercepts.

Finally, we came to the conclusion that correct answer is A.
