Answer:

2500

Step-by-step explanation:

If Jasjeet gave away 1%, that means she has 99% left.

Put the 99% over 100, so you can drop the % sign.

Then you're going to cross multiply that with 2475/ ?. The ? is the unknown aka original ammount of stamps. The 2475 is the 99% of stamps she still has.

A clerk at Agency Y has determined that at speeds of 25 pages per minute it is typical for 3 out of every 100 pages she photocop

nalin [4]

Answer:

180 pages

Step-by-step explanation:

Since her photocopy session is 25 pages per minute, the total number of pages photocopied in 4 hour session can be calculated as;

number of pages = time × speed

= (4 × 60) × 25

= 240 ×25

= 6000 pages

Thus, number of pages photocopied in 4 hours is 6000.

For every 100 pages, 3 would contain some type of printing error. The number of pages she expect with printing error during 4 hour session can be determined as;

= $\frac{6000}{100}$ × 3

= 60 × 3

= 180 pages

The expected number of pages with printing error during 4 hour photocopying session is 180 pages.

Area of rectangle is $2x^2+x-45$

Step-by-step explanation:

Given:

Length of rectangle = 2x-9

Width of rectangle = x+5

Required:

Area of rectangle

Formula:

$Area\,\,of\,\,rectangle=Length*Width$

Putting values of length and width:

$Area\,\,of\,\,rectangle=Length*Width\\Area\,\,of\,\,rectangle=(2x-9)(x+5)\\Area\,\,of\,\,rectangle=2x(x+5)-9(x+5)\\Area\,\,of\,\,rectangle=2x^2+10x-9x-45\\Area\,\,of\,\,rectangle=2x^2+x-45$

So, Area of rectangle is $2x^2+x-45$

ira [324]

Answer:

Step-by-step explanation:

Given that for X the amount of credit card debt for U.S. adults under 35, is

having mean as 8724 dollars.

For this point estimate to be unbiased and most accurate we must ensure that

i) The sample represents the population

ii) Samples are drawn at random

iii) Sample sizes are sufficienly large.

Hence we see that C is not right as college students cannot represent the entire population. Tv poll cannot be said to be random since there may be a significant population who was not aware about this poll. A and B are right but B is better with more sample size.
