The median would be the middle data point. Let’s list the points
25, 26, 31, 39, 32, 57
Put them in order from least to greatest
25, 26, 31, 32, 39, 57
There is an even amount of data so take the two center points and divide by 2
31 + 32 = 63
Divide by 2
31.5
There would be an average of 31.5 strokes
Answer:
340 ft²
Step-by-step explanation:
perimeter of rectangle = 2 x (L+W) = 2L + 2W = 74 .....(1)
cost of two length : $1 x 2L
cost of two width: $3.50 x 2W
($1 x 2L) + ($3.50 x 2W) = $159
2L + 7W = 159 ....... (2)
(2) - (1) ... 5W = 85
W = 17
L = (74 - 2 x 17) / 2 = 20
dimension = 17 x 20 = 340 ft²
<span>The problem is as following :
</span>
<span>What is the solutions of 2|x−1|−4= −2
</span>
===============================================
<span />
Solution:
<span>The equation is ⇒⇒ 2|x−1|−4= −2 → add 4 to both sides
</span>
<span>∴ 2|x−1| -4 + 4= −2+4
</span>
<span>∴ 2|x−1|= 2 → divide over 2
</span>
<span>∴ |x−1|= 1
</span><span>
</span><span>According to absolute rules:
</span>
<span>∴ x-1 = 1 or x-1 = -1
</span>
<span> ∴ x = 2 or x = 0
</span>
<span>∴ x = {0,2}
</span>
So, the solution of the equation is {0,2}
Answer:
Yes
