So 119 out of 250 people had a pool in their backyard...119/250 = 47.6%
so out of 10,000 people, expected value of ones with a pool is :
47.6% of 10,000 ...
0.476 * 10,000 = 4760 people <===
Answer:
6.5 inch speakers for 17.99 is the better deal.
Step-by-step explanation:
Divide 17.99 by 6.5 to find the cost per inch for the 6.5 inch speakers, which is approx. 2.8 (rounded to the tenth).
Multiply 2.8 by 12 to get $33.60, which is obviously a better deal, as the 6.5 inch speakers are cheaper. Hope this helps.
A years old. Na but are you needing an equation ?
Ok so
250 left for student desks
250≥8n
n=number of desks
solve
divide both sides by 8
31.25≥n
round down since we cannot have a decimal desk
31 desks
but, the teacher has 1 desk also so add 1
31+1=32
Distance = sqrt(5- -6)^2 + (3- -6)^2)
= sqrt (121 + 81)
= sqrt 202
= 14.21 to nearest hundredth
