The square root of negative numbers is either "not allowed" (Case 1) or it results in imaginary roots (Case 2).
-8+ square root of -20 /24 "not allowed," Case 1
-8+ square root of -5/6 = -8 plus or minus i times sqrt(5/6)
5√6
= -8 plus or minus i times --------- (Case 2)

Answer:
The relative frequency of landing on red = 0.68 = 68%
Step-by-step explanation:
- The spinner has 4 equal sections; blue, green, yellow, and red.
- It is spun 100 times.
- It lands on blue 14 times, green 10 ten times, yellow 8 times, and red 68 times.
The relative frequency of landing on red? Express your answer as a percent.
The relative frequency of landing on any section = (number of times the spinner lands on that section) ÷ (total number of times the spinner is spun)
The relative frequency of landing on red = (68) ÷ (100) = 0.68.
In percentage, 0.68 = 68%
Hope this Helps!!!
Answer:
4 pack priced at £2.04 is better value deal.
Step-by-step explanation:
The 4 pack is priced at £2.04
cost of one pack will be equal total price divided by no. of roll in one pack
cost of one pack will be £2.04
/4 = £0.51
The 9 pack is priced at £4.68
cost of one pack will be £4.68
/9 = £0.52
As price per toilet roll for 4 pack is £0.51 which is less than
price per toilet roll for 9 pack which is £0.52
4 pack priced at £2.04 is better value deal.
Answer: 7
Explanation:
List out the factors of 120 until we hit a gap
1,2,3,4,5,6,8
Note that 7 is not shown above. We can see that 120/7 = 17.14 approximately meaning that 7 doesn't go evenly into 120. So this is why 7 isn't a factor. Something like 3 is a factor because 120/3 = 40 is a whole number result.
Also, 7 is prime. The only factors of 7 are 1 and itself. This means that 7 and 120 do not have any common factors other than 1. The GCF of 7 and 120 is 1, leading to the two numbers being relatively prime
Side note: The term "coprime" is sometimes used in place of "relatively prime"
