- Find square root of 144 by factorisation method.
We can find the square root of 144 using the factorisation method. In this method, you need to factorise 144 first. Then, you'll get your answer in the form of prime factors. In this case, it's ⇨ 2 × 2 × 2 × 2 × 3 × 3.
__________________
To find the square root using factorisation, we need to group the same number in pairs. That is, 2 × 2 × 2 × 2 × 3 × 3 by grouping same numbers in pairs will become ⇨ (2, 2), (2, 2), (3, 3).
__________________
Now, you should take only 1 of the number from these groups. So, (2, 2), (2, 2), (3, 3) will change to ⇨ 2 × 2 × 3.
__________________
Finally, just multiply this set of numbers to find the square root of 144. 2 × 2 × 3 = 4 × 3 = ⇨ square root of 144.

Start with 7-4=3
Then 3x3=9
Then 18+9=27
Answer 27
Answer:
the theoretical probability is 1/5.
the experimental probability is 3/10.
chances are the experimental probobility will approach the theoretical probobility.
Step-by-step explanation:
since blue is one of five equal sizes, the probobility that it will land on blue is 1/5.
the expiromental probobility is the number of times it landed on blue devided by the number of spins. 15/50. this can be simplified by pulling out a 5, leaving us with 3/10.
last it stands to reason that the more times the spinner is spun the closer the experimental probability will model the theoretical probability.
Answer:
24.0
Step-by-step explanation:
17x17=289x2=578 sqrt578=24.01
The actual amount of snowfall is 4.2 inches.
<h3>What is percentage error?</h3>
Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.
Expected amount: 3 inches.
Actual amount: x inches.
Percentage error = (x- 3)/3 *100%
40= (x- 3)/3 *100%
0.4*3= x-3
1.2 = x-3
x= 4.2 inches.
