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%

**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"
