Answer:
2 2/3 hours
Step-by-step explanation:
Before it was 5 hours for 1 guitar, or 5 hours/guitar
Now it is 7 guitars in 3 hours or 7/3 hours/guitar
7/3 = 2 1/3
5 hours - 2 1/3 hours = 15/3 hours - 7/3 hours = 8/3 hours = 2 2/3 hours
The reduced the time it takes to build 1 guitar by 2 2/3 hours.
The Answer is Cross Products
2/3-> 4/6
1/2-> 3/6
Subtract
1/6
2/5-> 16/40
1/8-> 5/40
Subtract
11/40
The probability of a normally distributed data with mean, μ and standard deviation, σ, exceeds a value, a, is given by
<span>Given that the
average yearly snowfall in chillyville is normally distributed with a
mean of 55 inches. If the snowfall in chillyville exceeds 60 inches in
15% of the years, thus we have:
Therefore, the standard deviation is approximately 5.

Using the given information, the length of WZ is 8
<h3>Length of a line </h3>
From the question, we are to find the length of WZ
From the given information,
Y is the midpoint of WZ
and
X is the midpoint of WY
First,
We will create a line that models the given description
<u>W X Y Z</u>
2
From the given information,
XY = 2
Since X is the midpoint of WY
Then,
WX = XY
∴ WX = 2
Thus
WY = WX + XY
WY = 2 + 2
WY = 4
Also,
Y is the midpoint of WZ
Then,
WY = YZ
∴ YZ = 4
Thus,
WZ = WY + YZ
WZ = 4 + 4
WZ = 8
Hence, the length of WZ is 8
