Answer 1

Answer:

A = 4.5

B = 40.5

C = 4π or 12.566

D = 16

Step-by-step explanation:

A

6 x .5 = 3

3 x .5 = 1.5

1.5 x 3 = 4.5

B

12 x 3/4 = 9

1/2 (9)(9) = 40.5

C

8 x .25 = 2

π2² = 4π or 12.566

D

24 x 1/3 = 8

6 x 1/3 = 2

2 x 8 = 16

Blue Star is starting a new distribution service that delivers auto parts to the service departments of auto dealerships in the local area. Blue Star has found two light-duty trucks that would do the job well, so now it needs to pick one to perform this new service. The Ford TriVan costs $28,000 to buy and uses regular unleaded gasoline, with an average fuel efficiency of 24 miles per gallon. The TriVan has an operating cost of $.20 per mile. The Honda CityVan, a hybrid truck, costs $32,000 to buy and uses regular unleaded gasoline and battery power; it gets an average of 37 miles per gallon. The CityVan has an operating cost of $.22 per mile. The distance traveled annually is estimated to be 22,000 miles, with the life of either truck expected to be 8 years. The average gas price is $4.25 per gallon.

Required:
a. Based on life cycle cost, which model truck is the best choice?
b. How many miles does Blue Star need to put on a truck for the costs to be equal?
c. What is the crossover point in years?

Answers

Answer:

Blue Star

a.                                   The Ford TriVan   The Honda CityVan

Total life-cycle costs          $94,368                $90,936

Based on life cycle cost, the Honda CityVan is the best choice.

b. Blue Star needs to put on the Ford TriVan 9,032 miles more for the cost to be equal with the Honda CityVan's.

c. The crossover point in years = 5 months

Step-by-step explanation:

a) Data and Calculations:

                                        The Ford TriVan   The Honda CityVan

Purchase costs                  $28,000                 $32,000

Fuel efficiency per gallon   24 miles                 37 miles

Operating cost per mile     $0.20                     $0.22

Total operating costs         $4,400                   $4,840

Estimated annual distance 22,000 miles        22,000 miles

Gallons of fuel consumed  916.7 (22,000/24) 594.6 (22,000/37)

Total cost of fuel                 $3,896                  $2,527

Fuel cost per mile              $0.18                      $0.115

Total cost per mile             $0.38                     $0.335

Expected life of truck         8 years                   8 years

Average gas price = $4.25 per gallon

Total costs:

                                        The Ford TriVan   The Honda CityVan

Annual costs:

Total operating costs         $4,400                   $4,840

Total cost of fuel                $3,896                   $2,527

Annual costs                      $8,296                   $7,367

Life cycle costs:

Annual costs for 8 years   $66,368                $58,936

Purchase costs                  $28,000                $32,000

Total life-cycle costs          $94,368                $90,936

Difference in costs between Ford TriVan and Honda CityVan = $3,432 ($94,368 - $90,936)

Miles to put on the Ford TriVan for the life cycle cost to be equal to the life cycle cost of the Honda CityVan

= Difference in costs divided by total cost per mile of the Ford TriVan

= 9,032 miles ($3,432/$0.38)

Annual distance = 22,000 miles

Monthly distance = 1,833 miles

9,032/1,833 = 4.93 months or 5 months approximately

the probabilities that amy and tess will arrive at party on time are 2/3 and 3/4 respectively. Find the probability that a. amy will arrive on time while tess is not

Answers

Answer:

1/6

Step-by-step explanation:

Probability that any arrives on time = 2/3

Probability that teaa arrives on time = 3/4

Probability that teas will not arrive in time = 1 - P(tess arrives on time) = 1 - 3/4 = 1/4

Hence,

The probability that Amy arrives in time and tess does not equals

2/3 * 1/4 = (2*1) / (3*4) = 2 / 12 = 1/6

Using it's concept, it is found that there is a 0.1667 = 16.67% probability that Amy will arrive on time while Tess will not.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

The probability that Amy arrives on time is of 2/3.The probability that Tess does not arrive on time is of 1/4.

Since they are independent, we multiply them, hence:

[tex]P = \frac{2}{3} \times \frac{1}{4} = \frac{2}{12} = 0.1667[/tex]

0.1667 = 16.67% probability that Amy will arrive on time while Tess will not.

Step-by-step explanat

The expressions that are the result of decreasing x by 80% will be (1 - 0.80)x, x - (80/100)x, and (20/100)x. Then the correct options are A, C, and E.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The expressions that are the result of decreasing x by 80%.

We know that if something is decreased by a percentage p% then the percentage is written as (1 - p%). Then the expression is written as,

⇒ [(100 - 80) / 100]x

Then the expression can be written as,

⇒ [(100 - 80) / 100]x

⇒ x - (80/100)x

⇒ x - 0.80x

⇒ (1 - 0.80)x

⇒ 0.20x

⇒ (20/100)x

The expressions that are the result of decreasing x by 80% will be (1 - 0.80)x, x - (80/100)x, and (20/100)x. Then the correct options are A, C, and E.

I hope this helps you

Approximately 73 Great Danes weigh more than 125.8 lbs.

Mean [tex]\mu[/tex]=115 lb.

Standard deviation [tex]\sigma[/tex] =5.4 lb.

What is a z-score?

Z-score depicts how much a given value differs from the standard deviation.

[tex]z=\frac{x-\mu}{\sigma}[/tex]

[tex]z=\frac{125.8-115}{5.4}[/tex]

[tex]z=2[/tex]

From the standard normal table P-value corresponding to z=2 i.e. P(x>125.8) = 0.02275

Total population =3200

3200*0.02275 = 72.8 ≈73

Thus, approximately 73 Great Danes weigh more than 125.8 lbs.

Answer:

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

Center: (−2, −5); radius= 1

This means that [tex]x_0 = -2, y_0 = -5, r = 1[/tex]. So

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - (-2))^2 + (y - (-5))^2 = 1^2[/tex]

[tex](x + 2)^2 + (y + 5)^2 = 1[/tex]

This is the equation of the circle.

Which is an equation in terms of x and y for this function? graph of a function is a line that passes through the coordinates (2, 11) and (8, 14).

Answers

Answer:

y = 1/2x + 10  

Step-by-step explanation:

I'm not sure if this is right but:

First you work out the gradient of the line which is the difference in y divided by the difference in x:  

Gradient = (14 - 11) ÷ (8 - 2) = 3 ÷ 6 = 1/2    

the gradient is 1/2 so you'd write that as: y= 1/2x + c

Then you need to work out the y-intercept ( c )  

You do this by substitution:

14 = 1/2(8) + c

14 = 4 + c

c = 10

So the y-intercept is 10 so you'd write that as:

y = 1/2x + 10

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

Della has over 500 songs on her mobile phone, and she wants to estimate what proportion of the songs are by a female artist.

She takes an SRS of 50 songs on her phone and finds that 20 of the songs sampled are by a female artist.

The 99% confidence interval for the proportion of songs on her phone that are by a female artist will be

[tex]\rm x = 20\\\\n = 50 \\\\p = \dfrac{20}{50} = 0.4\\\\z= 99\% \ confidence\ interval = 2.58[/tex]

Then we know that
