• first factorise out 10:
• then find factors of the quadratic equation in the bracket:
Answer:
Answers may vary but will most likely be close to 2.
Step-by-step explanation
- Given:
first test:38%
second test:76%
SIMULATION FIRST TEST
Randomly select a 2-digit number.
If the digit is between 00 and 35 then you passed the test,else you did not pass the test.
SIMULATION SECOND TEST
Randomly select a 2-digit number.
if the digit is between 00 and 75 then you passed the test,else you did not pass the test.
SIMULATION TRIAL
Perform the simulation of the first test.if you did not pass the first test then perform the simulation of the second test.
Record the number of trials needed to pass the first or second test.
Repeat 20 times and take the average of the 20 recorded number of trials
(what is the sum of recorded values divided by 20).
Note:you will most likely obtain a result of about two trials needed.
Answer:
As you can see when you list out the factors of each number, 3 is the greatest number that 21 and 33 divides into.
Step-by-step explanation:
As you can see when you list out the factors of each number, 3 is the greatest number that 21 and 33 divides into.
No? I'm pretty sure it wouldn't be because 25 to 16 and then 5 to 4 if you multiplied by 5 it would be 25 to 20 so no.
Solution:
As one of the fraction is a proper fraction and another one is Mixed fraction.
There are two methods of solving it.
1. 
2. ![\frac{1}{2}\times-4 \frac{4}{5}=\frac{1}{2}[-4-\frac{4}{5}]=\frac{1}{2}\times (-4)+\frac{1}{2}\times\frac{-4}{5}=-2+\frac{-2}{5}=\frac{-10-2}{5}=\frac{-12}{5}=-2\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes-4%20%5Cfrac%7B4%7D%7B5%7D%3D%5Cfrac%7B1%7D%7B2%7D%5B-4-%5Cfrac%7B4%7D%7B5%7D%5D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%28-4%29%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%5Cfrac%7B-4%7D%7B5%7D%3D-2%2B%5Cfrac%7B-2%7D%7B5%7D%3D%5Cfrac%7B-10-2%7D%7B5%7D%3D%5Cfrac%7B-12%7D%7B5%7D%3D-2%5Cfrac%7B2%7D%7B5%7D)
→→Here i have used Distributive property with respect to addition and Subtraction i.e a×(b+c)= a ×b + a×c or a×(b-c)=a×b-a×c
Now, you can fill the blanks by yourself.
