Simplify the expression -(6 - 4p)

Illusion [34]

Hey there!

The answer to your question is $-6+4p$

Given:

$-(6-4p)$

First, we distribute the negative sign to both terms ( $6$ $and$ $-4p$ ) This would make the $6$ negative and the $-4p$ positive, so we have:

$-6$ $and$ $4p$

Add them together and we get:

$-6+4p$

Have a nice day!

Answer:

Boxplot A

Step-by-step explanation:

Given the data:

22, 25, 50, 58, 28, 24, 25, 51, 43, 32, 49, 38

We should obtain the 5 number summary and check which boxplot correctly displays the information :

Reordered data : 22, 24, 25, 25, 28, 32, 38, 43, 49, 50, 51, 58

. Maximum = 58

Minimum = 22

Lower quartile : 1/4(n+1)th term

n = 12

1/4(13)th term = 3.25

(3rd + 4th) = (25 + 25) /2 = 25

Median :

1/2(13)th = 6.5th term

(32 + 38) /2 = 35

Upper quartile :

3/4(13)th term 9.75 term

(49 + 50) / 2

= 49.5
