Answer:
perimeter = 4x³ + 3x² + 2
Step-by-step explanation:
perimeter = sum of the lengths of the sides
perimeter = 2x³ + 3x³ - x² - x³ + 4x² + 2
perimeter = 4x³ + 3x² + 2
55 is your answer
each number added together sums up to $330
there are 6 numbers
if you divide 330 by 6 you will get 55
Answer:
i predict the 150 will have defects
Step-by-step explanation:
you do 280 divided by 4 which gives you 70
then 10,500 divided by 70 which gives you
In
order to solve for a nth term in an arithmetic sequence, we use the formula
written as:<span>
an = a1 + (n-1)d
where an is the nth term, a1 is the first value
in the sequence, n is the term position and d is the common difference.
First, we need to calculate for d from the given
values above.
<span>a3 = 20.5 and a8 = 13
</span>
an = a1 + (n-1)d
20.5 = a1 + (3-1)d
</span>an = a1 + (n-1)d
13 = a1 + (8-1)d
<span>
a1 = 23.5
d = -1.5
The 11th term is calculated as follows:
a11 = a1 + (n-1)d
a11= 23.5 + (11-1)(-1.5)
a11 =
8.5</span>
A normal distribution is symmetrical about the mean. Therefore half of all young men are shorter than 68 inches.
