Proximately 32, 800 citizens of the country died in my automobile accident in 2015. Expressed this toll in deaths per day
Anton [14]
Remark
2015 is an odd numbered year. It is not a leap year. It has 365 days in it.

Equation
Total deaths = deaths / day * number of days

Givens
Total deaths = 32800
deaths / day = ???
number of days  = 365

Sub and solve
32800 = x * 365  Divide by sides by 365
32800 / 365 = x
x = 89.86 deaths per day.

Problem
Do you round up, down or leave the number as it is?

I would round up 90 deaths per day. 

Discussion 
Just how much are you out?
Total deaths in a year (rounded) = 90 * 365
Total deaths in a year (rounded)= 32850 which is 50 too many

Suppose you round down 
Total death/day = 89 * 365 = 39485 Rounding up is going to be better if you round at all.

Perhaps you should not round the answer at all and leave it at
89.86 <<<<< answer.
If you have choices, please list them.

Q # 19. I need your help on this
Komok [63]

Solution:

we have been asked to find a function for the given sitatution

The given situation is

A movie store sells DVDs for $11 each. what is the cost C of n DVDs.

Cost of  1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.

Cost of  1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.

......................................................................................................................

.......................................................................................................................

Cost of  1 DVD is $11, then the cost of n DVDS will be nx11=$11n.

Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.

Hence the correct option is C=11n, Discrete.

Why are units of measure important when solving real-word problems?
dsp73
<h2>Answer:</h2>

In physics, we always measure quantities and compare them with a standard. That standard defines a unit of the quantity. Suppose you want to measure the length of a car, so you use a meter stick, which is the standard for measuring distances. Then, <em>why are units of measure important when solving real-world problems?</em> Well, because when solving problems that involve equations, they need to be dimensionally consistent, but what does it mean? it means that you can't add two terms having different units. For instance, you can't add apples with tables!
