Answer:

$18.19

Step-by-step explanation:

First - Convert all the percents into decimals by moving the decimal to the left twice, 15% -> 0.15, 7% -> 0.07

Second - Then, the discount, multiply & subtract , 20 * 0.15 = 3 -> 20 - 3 = 17

Third - Then, the tax, multiply & add, 17 *0.07 = 1.17 -> 17 + 1.17 = 18.19

Elanso [62]

Answer:

The median is 2

Step-by-step explanation:

Here, we want to get the median for the number of pencils

Firstly, we have to write out the numbers that form the box plot ; we have this as;

1,1,1,2,2,2,2,3,3,5

the median is sum of the 5th and 6th term divided by 2

The 5th term is 2

The 6th term is 2

So the median is;

(2 + 2)/2

= 4/2 = 2

Hi,

The answer to your question is either A or B. 

The y-intercept is at point (0,60). All the other options (C and D) do not make sense and just aren't logically. 

The y-intercept (0,60) literally shows that if a student studies 0 hours they can expect to score a 60 on the test. 

Thus, you're answer is option B.

Write an equivalent expression by distributing the
Taya2010 [7]

Answer:

-(-4.1b - 6c - 8) = 4.1b + 6c + 8

Step-by-step explanation:

Given

-(-4.1b - 6c - 8)

Required

Simplify

To solve this using distributive property, we simply open the bracket

-(-4.1b - 6c - 8)

This becomes

= -1 * -4.1b -1 * - 6c -1 * - 8

= 4.1b + 6c + 8

Hence;

-(-4.1b - 6c - 8) = 4.1b + 6c + 8
