She has 7 soccer trophies.
So lets assume she wants to display it in a straight line:
The 1st has 7 ways
The 2nd has 6 ways
The 3rd has 5 ways
The 4th has 4 ways
until the last.
Total = 7 × 6 ×5 × 4 × 3 × 2 × 1 = 5040 ways.
70% = 70/100
divide 70 by 100
=0.7
Answer:
$ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample
Step-by-step explanation:
Here
Z∝ =1.64
Standard Deviation=S= 0.21
Sampling Error= SE= 0.05
As Sampling Error is found by
SE= z * s/√n
√n= z*s/ SE
n= (z* s/ SE)²
We use the above formula to calculate N
N= ( Z * S/SE)²
N= (1.64 * 0.21/0.05)²
N= 28.9296= 28.93
Cost of N number of burgers
= Cost *N
= $1.29 * 28.93= $ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample
Lets see...
The answer is yes! This is because when you solve for a common denominator, you need to multiply the numerator by what you multiplied to get the denominator. I solved the problem for you, which is displayed in the picture below:
You can see that the answer in improper form is 8/3 and in proper form is 2 2/3. If you look at the work, I believe you can draw conclusions from there. I am not good at explaining and I apologize. Good luck on your homework, common denominators are not hard to solve and I bet you will do a wonderful job in solving questions like these! You will soon become a Master at solving these kinds of questions in about a day from now and/or when you get to the upper grades like me! :)
