Answer:
2
Step-by-step explanation:
The dimensions of the actual image are 8 inches long by 11 inches wide.
The new scale gives a drawing that is 32 cm long by 44 cm wide.
We use proportions to solve this. For the length of the actual image:
6/1 = 48/x
Cross multiply:
6*x = 48*1
6x = 48
Divide both sides by 6:
6x/6 = 48/6
x =8 inches
For the width of the actual image:
6/1 = 66/x
6*x = 66*1
6x = 66
Divide both sides by 6:
6x/6 = 66/6
x = 11
For the new scale image, use the new scale:
Length:
4/1 = x/8
Cross multiply:
4*8 = x*1
32 = x
Width:
4/1 = x/11
4*11 = x*1
44 = x

Answer:
<h2>12</h2>
Step-by-step explanation:
The Mean is the average of the numbers: a calculated "central" value of a set of numbers.
To calculate it:
• add up all the numbers,
• then divide by how many numbers there are.
We have: 18, 16, x, 9, 12, 23 - six numbers (<em>n = 6</em>) and <em>mean = 15.</em>
Substitute:
