Amy: x skirts
Betty: 2x skirts
Carol: (2x) + 7 skirts
If Amy has 18 less than Carol, than Carol's equation minus 18 equals Amy's equation:
[(2x) + 7] - 18 = x
+18 +18
(2x) + 7 = x + 18
- 7 -7
2x = x + 11
-x -x
x = 11
Input the solution for x into the girls equation to double check.
Amy: 11
Betty: 2(x)
2(11)
=22
Carol: (2x) + 7
22 + 7
=29
Does Amy have 18 less than Carol?
Carol - Amy = 18
29 - 11 = 18
18 = 18
the problem is solved
For a binomial experiment in which success is defined to be a particular quality or attribute that interests us, with n=36 and p as 0.23, we can approximate p hat by a normal distribution.
Since n=36 , p=0.23 , thus q= 1-p = 1-0.23=0.77
therefore,
n*p= 36*0.23 =8.28>5
n*q = 36*0.77=27.22>5
and therefore, p hat can be approximated by a normal random variable, because n*p>5 and n*q>5.
The question is incomplete, a possible complete question is:
Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.
Suppose n = 36 and p = 0.23. Can we approximate p hat by a normal distribution? Why? (Use 2 decimal places.)
n*p = ?
n*q = ?

Answer:
The ending cash balance is $12,800
Step-by-step explanation:
This is an addition and subtraction problem. We begin with the initial cash balance of $6,800. Next we are <u>"provided"</u> cash from various activities of $37,000. Based on the word used we can tell that this means we have to <em>add </em>this to our initial balance like so,
Now our balance is $43,000. Next we are told that Net Cash <u>"used"</u> in investing activities is $13,600 and <u>"used"</u> in financing activities is $17,400. Based on this word we can tell that this money is being <em>subtracted</em> from our balance.
Finally, we can see that the ending cash balance is $12,800

Answer:
the answer is 2
Step-by-step explanation:
2/3/1/3 were going to take 1/3 multiply it by 2/3 and switch the nume and the deno.
2/3 x 3/1 = 6/3
6/3 = 2
