Answer:
X Y
1 25
3 17
4 13
6 5
Step-by-step explanation:
All we need to do is substitute the x values into the equation and we will find the y values!
Answer:
(1) Required function is . (2) Slope of line is .
Step-by-step explanation:
1)
The function passing through (-3,9), (-1,3), (0,0) and (3,-9).
From these points it is noticed that the value of function decrease by 6 if the value of x increases by 2 and y-intercept is (0,0).
Slope intercept of a line is
Where, m is slope and b is y-intercept.
So, function is defined as
The required function is .
2)
It is given that the line joining two points (10, 9) and (40, 3).
Slope of line is
Therefore slope of line is .
Answer:
European explorers, like Christopher Columbus, were the first to cross the great oceans of the world.
Answer:
Head: 113.04 in³
Basketball: 33.5 in³
Step-by-step explanation:
suppose Ronnie's head and basketball are spheres
V = 4/3πr³
Head: V₁ = 4/3 * 3.14 * 3³ = 113.04
Basketball: C = 2πr
r = C / 2π = 12.57 / 6.28 = 2.00 (it's a small ball :))
V₂ = 4/3 * 3.14 * 2³ = 33.49
The value closest to predicted value is 1.258
Step-by-step explanation:
The question requires you to substitute the value of x=4.8 in the least-squares regression line
The equation given is log (y)= 7.3 - 1.5x
Replacing x with real value, 4.8 you will have;
log(y) = 7.3 - 1.5(4.8)
log(y)= 7.3-7.2
log(y)=0.1
y=10^0.1
y=1.258
