If she answered all then she would have gotten 179 wrong. If I understand 200 questions and 11% on the test then 179 wrong and 21 right. So if you are asking how many she did not answer I would assume the questions she got wrong were the questions she did not answer which would be 179.

Answer:
$173493.8
Step-by-step explanation:
Data provided in the question:
LSRL for the data is ? = 3.8785x + 18.3538
Here,
x is area in 100 square feet
and
price in thousands of dollar
Thus,
For the given area 4000 square foot
x = 4000 ÷ 100 = 40 [Area in 100 square feet]
Therefore,
Using the given equation
Price = 3.8785(40) + 18.3538
or
Price = 173.4938 in thousands of dollar
or
Price = 173.4938 × $1000
Price = $173493.8
Answer:
11+2n
Step-by-step explanation:
Arithmetic sequence=a+(n-1)d
a=first number
n=nth term
d=difference
a=9
n=?
d=-2
So let's solve
9+(n-1)(-2)
9+(2n+2)
9+2n+2
Collect like terms
9+2+2n
11+2n
So the nth term is 11+2n
Total number of hours=18 hrs
Number of engineers=3
So divide number of hours by number of engineers.
18/3=6 hours
