A bag has 5 red marbles, 6 blue marbles and 4 black marbles
so total no. of marbles = 5 + 6 + 4 = 15
now probability of picking a black marble = 4/15
after replacement again probability of picking black marble is 4/15
it is given that black marble is picked two times
so probability of picking black marble two times or picking , replacing , and then picking is 4/15*4/15 = 16/225
Circumference formula: diamter*pi=7pi
Area = pi*r^2=pi(3.5)^2=12.25pi.
No, all three lines are parallel. If line c was perpendicular to the line a, and because line b is parallel to the line a, both line a and b would be perpendicular to the line c (line b has to be parallel to the line c, therefore it's impossible)
Answer:
1-x represents the percent of the original price being paid.
Step-by-step explanation:
The expression 24(1−x) gives the discounted price of a pair of shorts, where x is the percent of the discount written in decimal form.
For example , 10% is the discount percentage
1 - 10% = 90% will be the percentage of original price to be paid
Here x represents the percent of the discount
so 1-x represents the percent of the original price being paid.
