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]

Answer:

Step-by-step explanation:

The value of 7 in 2,751 is 700 since 7 is in the hundred place in the value

The value of 7 in 7,433 is 7000, since 7 is in the thousand place in the value.

In order to know how many times the 7 in 2,751 is more than 7 in 7,433, we will take the ratio of 700 to 7000 as shown:

ratio = 700:7000

ratio = 700/7000

ratio = 0.1

Hence the value of the 7 in 2,751 is 0.1 times the value of the 7 in 7433

Answer:

0.01?

Step-by-step explanation:

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

Answer:

The next three terms are 55,89 and 144

Step-by-step explanation:

We want to predict the next three numbers in the pattern

3, 5, 8 , 13 , 21 , 34

The difference between two successive terms is written between them.

Thus, we have

3 2 5 3 8 5 13 8 21 13 34

So the rule here is to add the next term to the previous so as to get the next coming term

Thus, we have;

34 + 21 = 55

55 + 34 = 89

89 + 55 = 144

Answer:

78.5

Step-by-step explanation:

We have the perimeter of the square, which is 40, and 40/4=10. In this picture, we see that the circle's diameter is the same as the length of one side of the square. Therefore, the diameter of the circle is 10. The are formula for circles is [tex]\pi r^{2}[/tex], where [tex]r[/tex] is the radius. The radius of the circle is just the diameter divided by 2, and 10/2=5. Now, [tex]5^2[/tex] is 25, and [tex]3.14\cdot25=78.5[/tex].

Answer:

-2.4 meters

Step-by-step explanation:

-86 + 83.6 = -2.4

Answer:

1) if the manufacturer's assumptions are correct, it would reed to replace 0.62% of its batteries free.

2) a standard deviation of 6.0843 results in a 1.07% replacement rate

3) using the revised standard deviation for battery life, 91.9% of the manufacturer's batteries don't get free replacement but qualifies for the prorated credit

Step-by-step explanation:

based on the given data;

x will represent the random variable such that the lifetime of its auto batteries, is normally distributed with a mean of 45 months and a standard deviation of 5.6 months

so

x → N( U = 45, ∝ = 5.6)

Under the warranty, if a battery fails within 31 months of purchase, the manufacturer replaces the battery at no charges to the consumer.

if the battery fails after 31 months but within 54 months, the manufacturer provides a prostrated credit towards the purchase of anew battery

1) If the manufacturer's assumptions are correct,

p(x < 3) = p( [x-u / ∝ ] < [ 31-45 / 5.6] )

= p( z < -2.5 )

using the standard normal table,

value of z = 0.0062 ≈ 0.62%

so if the manufacturer's assumptions are correct, it would reed to replace 0.62% of its batteries free.

2)

The company finds that it is replacing 1.07% of its batteries free of charge. It suspects that its assumption standard deviation of the life of its batteries is incorrect, so a standard deviation of ? results in a 1.07%

so lets say;

p ( x < 31 ) = ( 1.07%) = 0.0107

p ( [x-u / ∝ ] < [ 31-45 / ∝] ) = 0.0107

now from the standard table

-2.301 is 1.07%

so

( 31 - 45 / ∝ ) = -2.301

-14 / ∝ = -2.301

∝ = -14 / - 2.301

∝ = 6.0843

therefore a standard deviation of 6.0843 results in a 1.07% replacement rate

3)

Using the revised standard deviation for battery life, what percentage of the manufacturer's batteries don't free replacement but do qualify for the prorated credit?

p( 31 < x < 54 ) = p ( [31 - u / ∝ ] < [ x-u / ∝]  < [ 54 - 45 / ∝] )

= p ( [31 - 45 / 6.0843 ] < [ x-u / ∝]  < [ 54 - 45 / 6.0843] )

= p ( -2.301 < z < 1.4792 )

= p(Z < 1.5) - p(Z < -2.3)

= 0.9393 - 0.0108

= 0.919 ≈ 91.9%

therefore using the revised standard deviation for battery life, 91.9% of the manufacturer's batteries don't get free replacement but qualifies for the prorated credit

Answer: y = 45

Step-by-step explanation:

the two angles will be supplementary to each other

4y - 45 + y = 180

Combine like terms

5y - 45 = 180

Add 45 to both sides

5y = 225

Divide both sides by 5

y = 45

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.

Answer:

12 weeks

Step-by-step explanation:

It will take Jackie 12 weeks to buy her car because she earns 172 per week.

If you divide 2000 buy 172 you end up with 11.6

if you multiply 11 and 172 you get 1,892 which is just a little under 2000

if you add another week = 172$ you will arrive at 2064 which is enough to buy  

her car.

Answer:

a

[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]
