Answer:

a=45

Step-by-step explanation:

1st step is to create a equation, since this is a right triangle, all the measurements add up to 90 so the equation should look like this 90=20+25+a now solve like this

90=20+25+a

90=45+a- combine like terms

-45. -45-subtract on both sides

45=a

The cost of renting a car is $29.00 a day plus $0.25 for every kilometre after the first 100km. What is the cost of renting the
ira [324]

Answer:

$461

Step-by-step explanation:

First, find the cost with the daily charge of $29.

Multiply 14 by 29, since the car was rented for 14 days:

14(29)

= 406

Find the cost with the distance traveled. Since there is only a charge after the first 100 km, subtract 100 from 320.

320 - 100

= 220

Find the charge by multiplying this by 0.25:

220(0.25)

= 55

Add this to the daily charge:

55 + 406

= 461

So, the cost will be $461

<h3>What is expected value?</h3>

The expected value is the long term average of the data or the mean of the data.

In order to better decide how to market a new line of clothing, Mary is researching the demographics of the customers of a certain clothing store.

She counted the number of customers who visited the store over the course of a month, and found out how many of the customers were high school students.

Her collected data is in the table below.

  • Week                1          2         3            4
  • Customers    2,848    3,141    3,861    3,911
  • Students       2,033    1,937   2,076    1,721

Mary predicts that the store will see 4,238 customers next week.

From using the long term mean value calculator for the provided data, the predicted value of the next week we get as 2392.

Hence, the number of high school students which should the store expect next week, Mary predicts that the store will see 4,238 customers next week is 2392.
