Answer: length of rectangular parking lot = 24 yards

Width of rectangular parking lot = 20 yards.

Step-by-step explanation:

Let L represent the length of the rectangular parking lot.

Let W represent the width of the rectangular parking lot.

The rectangular parking lot has a length that is 4 yards greater than the width. It means that

W = L - 4

The formula for determining the area of a rectangle is expressed as

Area = LW

The area of the parking lot is 480 square yards.. It means that

LW = 480- - - - - - - - - - 1

Substituting W = L - 4 into equation 1, it becomes

L(L - 4) = 480

L² - 4L = 480

L² - 4L - 480 = 0

L² + 20L - 24L - 480 = 0

L(L + 20) - 24(L + 20) = 0

L - 24 = 0 or L + 20 = 0

L = 24 or L = - 20

Since the length cannot be negative, then L = 24

W = L - 4 = 24 - 4

W = 20

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each sale
LenaWriter [7]

Based on the amount that both Salesmen A and B earn per sale, the number of sales they both had was 12 sales.

<h3>How many sales did Salesmen A and B have?</h3>

Sales commission is a key aspect of sales compensation. It's the amount of money a salesperson earns based on the number of sales they have been able to make.

We are told that;

Salesman A gets $65 per sale.

Salesman B gets $300 and $40 per sale.

Assuming the number of sales to take them both to the same amount is x, the relevant formulas would be:

65x = 300 + 40x

Rearranging gives;

65x - 40x = 300

25x = 300

x = 300/25

x = 12 sales

The amount that salesman A earned is = 65 * 12 = $780

The amount that salesman B earned is = 300 + (40 * 12) = $780

Gill rolls a number cube 78 times. How many times can he expect to roll an odd number greater than 1?
bekas [8.4K]
Im assuming its just a regular number cube with 6 numbers 
there are only 2 odd numbers above 1 ( 3 and 5) 

so the ratio is 2/6 

you want to know how manny times (x) will you roll those numbers out of 78 roll 
the ratio is x/78 

multiply 

(2/6) = (x/78) 

cross multply to give you 6x= 156 and divide by 6 

<span>to give you x = 26

The value of a car decreases about 7% percent each year after it is manufactured.The 2017 Honda Civic costs $19,540
Kitty [74]

Answer: a) , where 'A' is the value of car after 't' years.


b) $12446.784



Step-by-step explanation:


Given: A new car that sells for $21,000 depreciates (decreases in value) 16% each year.


Then a function that models the value of the car will be


, where 'P' is the selling price of car, 'r' is the rate of depreciation in decimal, 't' is the time in years and 'A' is the value of car after 't' years.


Thus after substituting given value, the function becomes




To find the value after 3 years, substitute t=3 in the above function.




Hence the value of car after 3 years=$12446.784

Consider the probability that greater than 77 out of 131 computers will crash in a day. Assume the probability that a given comp
sweet-ann [11.9K]

Answer:

A Normal approximation to binomial cannot be applied to approximate the distribution of <em>X</em>, the number of computer crashes in a day.

Step-by-step explanation:

Let <em>X</em> = number of computers that will crash in a day.

The probability of a computer crashing in a day is, <em>p </em>= 0.99.

A random sample of <em>n</em> = 131 is selected.

A random computer crashing in a day is independent of the others.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 131 and <em>p</em> = 0.99.

But the sample size is quite large, i.e. <em>n</em> > 30.

So the distribution of <em>X</em> can be approximated by the normal distribution if the following conditions are fulfilled:

  • np ≥ 10
  • n(1 - p) ≥ 10

Check whether the conditions satisfy or not:

np=131\times 0.99=129.69>10\\n(1-p)=131\times (1-0.99)=1.31

The second condition is not fulfilled.

A Normal approximation to binomial cannot be applied to approximate the distribution of <em>X</em>, the number of computer crashes in a day.
