Answer:
There is a 1/20 chance.
Step-by-step explanation:
60 times would be 1/60.But that would be 1 and there are two marbles.So there is a 1/20 chance
Answer:
2nd choice
Step-by-step explanation:
csc is 1/sin
cos x 1/sin will give you cos/sin, which is cot.
Answer:
Let t be the number of toys.
Since, the toy drive already has collected 300 toys
⇒ t+ 300
Also, it is given that the goal of a toy drive is to donate more than 1000 toys.
We get an inequality:
⇒
Solve an inequality:

Subtract 300 from both sides we get

Simplify:
t > 700
Therefore, more than 700 toys does the toy drive need to meet its goal.
An inequality is;
; t > 700
The calculus approach is to use Newtons Method:

where

Start with initial guess of "a".
After 4 or 5 iterations, you should get a close approximation to

...............
If you wanted a non-calculus approach, I would suggest divide and conquer.
First determine which 2 integers the sqrt lies in between by perfect squares.

Then use midpoint

for next guess, if

then repeat with "m" = midpoint. Otherwise repeat with "n" = midpoint.
Continue until you have a good approximation, about 6-8 decimal points.
