Answer: 0,1,5,5,8

Step-by-step explanation:

From the rule of five number summary, we have to solve and group the datasets into a single list ranging from the lowest to the highest.

On doing that , we'll have

0,0,0.5,0.5,1,1,2,2,3.5,5,5,5,5,5,5,5,7,8,8,8

From the grouping above, you can see that:

Minimum = 0

Q1 = 1

Median = 5

Q3 = 5

Maximum = 8

Therefore, the five number summary is:

0, 1, 5, 5, 8

Solve the following<br> 5 3/4 + (6 2/3 - 4 5/6) =
chubhunter [2.5K]

Answer:

7 5/12

Step-by-step explanation:

first, subtract 4 5/6 from 6 2/3 by converting 6 2/3 to 6 4/6

5 3/4 + (6 4/6 - 4 5/6) = 5 3/4 + 1 4/6

* I borrowed 6/6 or '1' from the 6 and made 4/6 into 10/6

5 3/4 equals 5 9/12 and 1 4/6 equals 1 8/12

adding them gives you:

6 17/12 which is the same as 6 + 1 5/12, or 7 5/12

5. Solve by using the square root property.<br>(x - 3)² +6=1​
Veseljchak [2.6K]

Answer:

x = 3 + i+√5

x = 3 + i-√5

OR

x= 4 - √6

x= 4 +√6

Step-by-step explanation:

(x - 3)² +6=1​

(x - 3)² + 6 = 1

        -6   -6

sq root > (x - 3)²      = -5

x-3 = i±√5     (i because neg. number)

x = 3 + i±√5

since its ±

two possible answers

x = 3 + i+√5

x = 3 + i-√5

Or

(x - 3)² +6=1​

(x-3)+  √6= √ 1

x-3 = 1 - (±)  √6

x= 4 - (±)  √6

Answers

x= 4 - √6

x= 4 +√6
