The markdown price
= the percent × regular price
the sale price
= regular price - markdown price
= regular price - the percent × regular price
= regular price×(1 - the percent)

Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

mv

=
r

mu

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Answer:
the answers have been provided below
Step-by-step explanation:
Population z score is given as (x-μ)/sd For a 32 to 35 week gestation period
μ= 2700
Sd = 900grams
x = 2225
z = (2225-2700)/900
z = -0.527
For a 40 week gestation period.
μ = 3000
Sd = 465grams
x = 2525
z = (2525-3000)/465
Z = -1.022
In answer to the question:
a. The 33-week gestation period baby weighs 0.53 standard deviations below the mean.
b. The 40-week gestation period baby weighs 1.02 standard deviations below the mean.
c. -1.022 < -0.527. the 40 weeks gestation baby weighs less.
A. The baby born in week 40 does since its z-score is smaller.
