Answer:
Blue and purple bars will change on the histogram
Step-by-step explanation:
Size of two bars will change
a) The blue bar with range 65 -70. This bar will reduce in size as three of its reading have shifted to another bar color
b) The purple bar with range 75-80. The size of this bar will increase in size as it will get three new entries from the blue bar

<h3><u>Answer :- </u></h3>
• 1 / 3
<h3><u>Explanation :- </u></h3>
<u>As </u><u>we </u><u>know</u><u> </u><u>that </u><u>,</u><u> </u>
If a dilation produces a smaller figure then ,
0 < Scale factor < 1 .
So then ,
Case 1 ) -2 => The scale factor must be a positive number .
Case 2 ) 1 / 3 => 0 < 1/3 < 1 => Is a possible scale factor .
Case 3 ) 1 => This scale factor does not produce a smaller figure , It produces the same figure .
Case 4 ) 4 => This scale factor produces a larger figure .
<h3>• Hence, the answer is 1/3 .</h3>

Answer:
–9(3x³ – 8x + 9)
Step-by-step explanation:
–27x³ + 72x – 81
The above equation can be factorised as follow:
–27x³ = –3 * 3 * 3 * x * x * x
72x = 2 * 2 * 2 * 3 * 3 * x
–81 = –3 * 3 * 3 * 3
Common factor = 3 * 3
Greatest common factor = 9
Thus,
–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)
–27x³ + 72x – 81 = –9(3x³ – 8x + 9)
Answer:
The decibel range is
Step-by-step explanation:
Let
d -----> the decibel level of the music
we know that
The absolute value of the difference of the decibel level of the music and its average, must be less than or equal to 28 decibels
so
The absolute value that represent this problem is
Solve the absolute value
<em>First solution (positive)</em>
Adds 110 both sides
<em>Second solution (negative)</em>
Multiply by -1 both sides
Adds 110 both sides
therefore
The decibel range is
