Step-by-step explanation:
It is a random sample of students because they are just random people that Jackie is asking, its not only people in on grade, or only people on the basketball team.
Answer:
approx 15%
Step-by-step explanation:
Allison puts $250 down and following that she makes 12 monthly payments of $124.49. The sum of her payments (total cost) is thus $250 + (124.49/month)(12 months) = $1743.88
The total interest she pays is $1743.88 - ($124.49/month)(12 months), or
$250
We use the simple interest formula: i = prt, where t is the number of years, and r is the interest rate as a decimal fraction:
$250 = $1599.99*r*1.
$250
Solving this for r by division, we get r = --------------- = 0.1463, or approx 15%
$1599.99
Given.
Radius of the Half sphere is 3 inches.
From the figure;
Radius of half sphere= Radius of cylinder= Radius of cone=3inches
Height of cone= 4inches.
Height of cylinder=6inches.
Volume of cone=(πr²h)/3
=(π3²×4)/3
=(12π) inch³
volume of cylinder= πr²h=π3²6=54π inch³
Volume of half sphere= (4/3) π r³=π(4×3³)/3 (1/2)=π×4×9/2=18π inch³
Total area of Composite figure=(12π +54π +18π) inch³
=84π inch³
=(84)× 22/7inch³
=12×22 inch³
=264inch³
Hope it helps...
