Answer:
Step-by-step explanation:
So 8/12 + 7/8 needs to be greater than 1 foot? It is.
8/12 = 2/3
7/8 + 2/3 =
7/8 = 3*7 / 8*3 = 21 / 24
2/3 = 8*2 /8*3 = 16 / 24
Now add them
21 / 24 + 16/24 = 37/24 which is way more than 1 foot.
37/24 = 1 13/24

Answer:
the length of the road after 25 days:L = 41 + 25
=66miles
Answer:
The mean of the cable length is
The standard deviation of the cable length is
Half of the cables lie in the specifications.
Step-by-step explanation:
<em>Point a:</em>
Suppose <em>X</em> is a continuous random variable with probability density function <em>f(x).</em>
The mean of a continuous random variable, denoted as <em>μ</em> or <em>E(X)</em> is<em> </em>
<em></em>
The standard deviation of <em>X</em> is
where is the variance of X
We know that the probability density function of the length of computer cables is
Applying the above definition of the mean we get
Applying the above definition of the standard deviation we get
First we need to calculate the variance of X
<em>Point b:</em>
To find what proportion of cables is within specifications you need to:
Answer:
1. diameter=8 kilometres
2. area=98.96 inches
3. 37m
Step-by-step explanation:
1. diameter= 2*radius
2. area of sector=θ out of 360*π where θ is the angle
3. area of garden=π
706.5=π
=706.5/π
= 225(nearest whole)
r==15m
we now use Pythagoras theorem to find length of each pathway
1600=225+
=1600-225=1375
x==37 m (to nearest whole)
