Answer:

The correct answer is A) $105

Step-by-step explanation:

In this real-world problem,  the cost to groom both dogs is (the puppy) + (the adult dog) = x.

For the first step, y = 40, if x <= 25.

y = 50, if 25 < x < 50.

if x >= 50, then y = 0.50x + 25

So therefore, substitute the puppy + adult dog = x

25 + 80 = x

105 = x

So, the final answer is $105.

Crude oil Imports to one country from another for 2009-2013 could be approximated by the following model where t is time in year
Mashutka [201]

Answer:

  • Time = approximately mid 2012
  • Oil import rate = 3600 barrels

Step-by-step explanation:

<h3><em>Unclear part of the question</em></h3>
  • I(t) = −35t² + 800t − 1,000 thousand barrels per day (9 ≤ t ≤ 13)
  • According to the model, approximately when were oil imports to the country greatest?  t =  ?
<h3>Solution</h3>

Given the quadratic function  

  • <em>The vertex of a quadratic function is found by a formula: x = -b/2a</em>

<u>As per given function:</u>

  • b = 800, a = -35

<u>Then</u>

  • t = - 800/2*(-35) = 11.43 which is within given range of 9 ≤ t ≤ 13

This time is approximately mid 2012.

<u>Considering this in the function, to get oil import rate for the same time:</u>

  • l(11.43) = -35*(11.43)² + 800*11.43 - 1000 = 3571.4285

<u>Rounded to two significant figures, the greatest oil import rate was</u>:

  • 3600 barrels

A summer camp cookout is planned for the campers and their families. There is room for 450 people. Each adult costs $7, and each
Tanya [424]

Answer:

\left\{\begin{array}{l}x+y\le 450\\7x+4y\le 1,150\end{array}\right.

Step-by-step explanation:

Let  x be the number of adults and y be the number of campers.

There are rooms for 450 people, so

x+y≤450.

Each adult costs $7, then x adults cost $7x.

Each camper costs $4, then y campers cost $4y.

There is a maximum budget of $1,150, so

7x+4y≤1,150

Hence, you get the system of two inequalities:

\left\{\begin{array}{l}x+y\le 450\\7x+4y\le 1,150\end{array}\right.

Amanda [17]

Answer: \mu_x=18\text{ hours}

\sigma_x=4\text{ hours}

Step-by-step explanation:

We know that mean and standard deviation of sampling distribution is given by :-

\mu_x=\mu

\sigma_x=\dfrac{\sigma}{\sqrt{n}}

, where \mu = population mean

\sigma =Population standard deviation.

n= sample size .

In the given situation, we have

\mu=18\text{ hours}

\sigma=6\text{ hours}

n= 2

Then, the expected mean and the standard deviation of the sampling distribution will be :_

\mu_x=\mu=18\text{ hours}

\sigma_x=\dfrac{\sigma}{\sqrt{n}}=\dfrac{6}{\sqrt{2}}=4.24264068712\approx4  [Rounded to the nearest whole number]

Hence, the the expected mean and the standard deviation of the sampling distribution :

\mu_x=18\text{ hours}

\sigma_x=4\text{ hours}
