Answer:
One piece of fabric: 10 x 6, or 60.
If one triangle is 15, she can cut 4 triangles from each piece of fabric.
If she has 24 pieces of fabric, she can cut 4 x 24, or 96 triangle patches.
Let me know if this helps!
Answer:
Mean = 35
Variance = 291.7
Step-by-step explanation:
Data provided in the question:
X : 1, 2, 3, 4, 5, 6
All the data are independent
Thus,
The mean for this case will be given as:
Mean, E[X] = 
or
E[X] = 
or
E[X] = 3.5
For 10 days, Mean = 3.5 × 10 = 35
And,
variance = E[X²] - ( E[X] )²
Now, for this case of independent value,
E[X²] = 
or
E[X²] = 
or
E[X²] = 
or
E[X²] = 15.167
Therefore,
variance = E[X²] - ( E[X] )²
or
variance = 15.167 - 3.5²
or
Variance = 2.917
For 10 days = Variance × Days²
= 2.917 × 10²
= 291.7
The total cost of the lease is $18,092.30.
<h3>What is the total cost of the lease?</h3>
The total cost of the lease is a function of the up front fee, payment per month and the total cost for miles over 36,000.
Total cost = $3500 + (384 x 12 x 3) + [0.15 x (41,122 - 36,000)]
$3500 + 13,824 + 768.30 = $18,092.30
