We are given
length of rectangular yard is x
so,
width of rectangular yard is
so,
We are given
the length of the enclosed yard is 50 feet
so, we get
now, we can plug x=50 and then we can find width
now, we can find total fencing length
so, total fencing length is
now, we can plug values
now, we are given
the cost of fencing is $13 per foot
so,
total cost = (cost of fencing)*(total fencing length)
we can plug values
So, Janice will spend $4030.........Answer
The measure of dispersion that measures how much the data differ from the mean is called the standard deviation.
<h3>What is standard deviation?</h3>
Standard deviation is a statistical measure of dispersion as opposed to the measure of central tendency like mean, median and mode.
The standard deviation is a measure of how spread out data values are around the mean.
It is defined as the square root of the variance and represented with the Greek letter σ.

Answer:
x=7 is the line parallel to the given line x=8 . Parallel lines are the lines which are always same distance apart and never intersect. The given line is x=8 with intersects the x axis at x=8 and it is parallel to y axis with slope infinite or not defined.
Step-by-step explanation:
Answer:
In option a, w < 10
in option b, w = 10 and 2(20) + 2(10) = 40 + 20 = 60 < 150
in option c, w > 10 but 2(60) + 2(20) = 120 + 40 = 160 > 150
In option d, w > 10 but 2(55) + 2(30) = 110 + 60 = 170 > 150
Therefore the corect answer is option b.
