Answer:
c) 44000 miles
Step-by-step explanation:
The regression line has the following format:
In which b is the slope(how much each mile costs) and a is the fixed number of miles flown.
In this problem, we have that:
. So
A person who spent $ 2000 is predicted to have flown:
This is y when x = 2000.
So the correct answer is:
c) 44000 miles
Answer:
Shell is under Red color cup
Step-by-step explanation:
We have 3 cups and 3 objects which they cover under them.
Taking into consideration (4) and (2) as they both describe the position related to bean
(4) Gray cup →Bean (right) (2) coin ← bean (left)
that means coin can either under Gray cup or left to gray cup.
Now
(1) Red ← White (left) (3) Shell → Gray (right)
This means if we consider coin to be left of gray cup then we can't place shell to the left of gray cup as required in (3)
so coin will be under gray cup
on forming the Color of cups and the coin below them
C1 C2 C3
Red Gray White
__ __ __
Shell coin Bean
So Shell is under Red color cup
Answer:
d
Step-by-step explanation:
when f(x)=5......It can also be
f(x)=1/125(625x)
every whole number over one...1(625x)=625x
also 125(1)=125 therefore (625/125)x=5x
Height of a trapezoid:
h = 5 · sin 80° = 5 · 0.985 = 4.924
x = 5 · cos 80° = 5 · 0.17365 = 0.868
7 - x = 7 - 0.868 = 6.132
By the Pythagorean theorem:
d² = 6.132² + 4.924²
d² = 37.6 + 24.25
d² = 61.85
d = √61.85
d = 7.86 ≈ 8
Answer: The length of a diagonal brace is 8 feet.
Serious high school. This is one of the few differential equations I can solve.
The usual particular solution is 
because 
is its own derivative.
An independent solution is 
which has a negative sign in the first derivative which turns back to positive in the second.
The arbitrary linear combination spans the solution space:
But we only are asked for the basis.
