Answer:
i think its B or D sorry if I'm wrong
You would evaluate by plugging in the given number of 7 to get your answer.
Answer:
rom the relation for linear regression formula, Y = b·X + a, we have ;
For car 1
ΣXY = 102780
(ΣX)² = 36
ΣX = 6
ΣY = 52390
ΣX² = 14
N = 3
b = -1000
a = 19463
Y = -1000×X + 19463
For Car 2
ΣXY = 102539.8
(ΣX)² = 36
ΣX = 6
ΣY = 52346.6
ΣX² = 14
N = 3 .
b = -1076.7
a = 19602
Y = -1076.7×X + 19602
Step-by-step explanation:
part B ^
Hello, There are endless expressions. Since, you multiply this fraction by a costant k / k
If k = 2
Then,
(5/9) = ( 5/9) × ( k / k)
= (5/9) × ( 2/2)
= (5 × 2 / 9×2)
= 10 / 18
________________
The only restriction for k is zero and the infinite. Because there is no "0/0" and "infinito/ infinito" at math.
Answer:
the best option would be to swim
Step-by-step explanation:
Hello! To solve this problem we must follow the following steps.
1. remember the concept of uniform motion with constant speed, which establishes the following equation

where
t=time
x=distance
V=speed
2. Calculate the time it takes to swim and calculate the time it takes to walk
walking:
x=10mile
v=5milles/h

swimming
x=1mile
v=3milles/h

3. Compare both results and choose the one with the least time.
as you can see it takes less time swimming, so this would be the best way
