The price of a swimming pool
Goryan [66]

Answer:

  • Sales\:\:Price=List\:\:Price-Discount
  • Sales price= $1167.25 List price=L Discount=19.5\%\:of\:L=0.195L
  • 1167.25=L-0.195L

Step-by-step explanation:

The percentage discount is 19.5\%

The discount is always given on the list price.

Sales\:\:Price=List\:\:Price-Discount

Let the list price be L, then

List price=L

Sales price= $1167.25

Discount=19.5\%\:of\:L=0.195L

We substitute into the equation to get:

1167.25=L-0.195L

1167.25=0.805L

Divide both sides by 0.805

\frac{1167.25}{0.805}=L

1450=L

The list price of the swimming pool is $1450

luda_lava [24]

Answer:

Step-by-step explanation:

Given that a  survey showed that 72​% of adults need correction​ (eyeglasses, contacts,​ surgery, etc.) for their eyesight

X - number of people who need correction for their eyesight

X is binomial since each event is independent and there are only two outcmes.

X (18, 0.72)

Required probability = the probability that no more than 1 of them need correction for their eyesight.

=P(X=0)+P(X=1)=0.00000296+0.000137

=0.00014

Yes 1 is a significantly low number as probability is almost zero.
