The average thickness of her books is 2.8 cm. Hope this helped!!
I think that it’s 24 as I can see by the form it’s a Microsoft teams test form lol

Answer:
- 11, 11, 24, 34, 45 and 23
===========================
<h3>Given data</h3>
- 9, 11, 11, 16, 16, 24, 28, 30, 34, 42, 45
<h3>Five-number summary</h3>
<u>Minimum</u>:
- The smallest number of data ⇒ 11
<u>Maximum</u>:
- The largest number of data ⇒ 45
<u>Median</u>:
- The middle number of the data if data consists of odd number of elements ⇒ 24
<u>Lower quartile</u>:
- The median of the lower half of data, 9, 11, 11, 16, 16 ⇒ 11
<u>Upper quartile</u>:
- The median of the upper half of data, 28, 30, 34, 42, 45 ⇒ 34
<u />
<h3>Interquartile range</h3>
- The difference of upper and lower quartiles, 34 - 11 = 23
Answer:
x = -7, y = 5
Step-by-step explanation:
Sub the value of y into the first equation
2x + 3(-2x - 9) = 1
2x - 6x - 27 = 1
-4x -27 -1 = 0
-4x - 28 = 0
-4x = 28
x = 28 / (-4)
x = -7
Sub the x value into the second equation
y = -2 * (-7) - 9
y = 14 - 9
y = 5
Answer:
x = 3
Step-by-step explanation:
This is in vertex notation which means that it is written in y = (x-h)^2 + k format where the vertex is (h,k). In this case the vertex is (3,2) which means that at the x-axis of 3, that is where the parabola is mirrored and is in fact the axis of symmetry
