Jayden has been reading a 275275275-page book for english class. on average, he has read about 101010 pages in 151515 minutes (\

<span>75 pages.
   OK. Lots of copying errors here. I'll be using 275 page book, reading 10 pages per 15 minutes, skimming 15 pages per 10 minutes, 5 hours and 50 minutes to complete the book.
   To make things easier, first convert the time to just minutes. So 5 * 60 + 50 = 300 + 50 = 350 minutes.

   Now let's use the variable X for the number of minutes spent skimming and (350-X) for the number of minutes spent reading.
 X * 15/10 + (350 - X)*10/15 = 275

   Solve for X.
 X * 15/10 + (350 - X)*10/15 = 275
 X * 15/10 + 350*10/15 - X*10/15 = 275
 X * 15/10 - X*10/15 = 275 - 350*10/15
X(15/10 - 10/15) = 275 - 3500/15
 X(45/30 - 20/30) = 825/3 - 700/3
 X(25/30) = 125/3
 X = 125/3 * 30/25 = 125/1 * 10/25 = 5/1 * 10/1 = 50/1 = 50
   So Jayden spent 50 minutes skimming. And at the rate of 15 pages every 10 minutes, he skimmed 50*15/10 = 750/10 = 75 pages.</span>

A shipment of 8 tons of sugar is separated into containers of equal size. If the shipment fills 3 1/3 containers, how much sugar
liubo4ka [24]
Take 8 and divide it by 3 1/3. to make it easer 1/3 could be .3 as a decimal.
so 8 divided by 3.3.
8/3.3= 2.42
so it would be 2.42 tons of sugar per container.

Maslowich

Answer:

n = 4

x = 2

p = 38\%

q = 62\%

Step-by-step explanation:

Required

Find n, x, p and q

n always represent the population surveyed;

So:

n = 4

x represents the sample from the population

So:

x = 2

p always represents the given proportion

p = 38\%

Solving for q

p + q = 1

q = 1 - p

q = 1 - 38\%

q = 62\%
