In general, the intercept of the function F(X) = a•b^x is the point
Murljashka [212]

Answer:

(0,a)

Step-by-step explanation:

Given

f(x) = ab^x

Required

Determine the intercept

The intercept is at point: x = 0

So, we have:

f(0) = ab^0

f(0) = a*1

f(0) = a

So, the intercept is at point (0,a)

<em>None of the options is true</em>

A line passes through the two given points. Is it vertical , horizontal ,or neither ? (8, 3), (8, -4) Vertical Horizontal Neithe

Consider a population list x, with a CV= 10%. A second population list, y, has a CV= 20%. The linear regression of y on x is y =
ch4aika [34]

Answer:

The correlation coefficient 0.5 depicts that there is moderate positive correlation between y and x.

Step-by-step explanation:

The linear regression equation is

y= a+bx

The given linear equation is

y= 10x

Here, slope=b=10 and intercept=a=0.

From above equation,

ybar=10xbar

We are given that CVx=0.1 and CVy=0.2

where CV=(standard deviation/mean)*100

We know that

b=r(Sy/Sx)

Multiplying by xbar/ybar on both sides

(xbar/ybar)b=r(Sy/Sx)(xbar/ybar)

(xbar/ybar)b=r[(Sy/ybar)/(Sx/xbar))]

(xbar/ybar)b=r[CVy/CVx]

As CVy/CVx=(Sy/ybar)*100/(Sx/xbar)*100=(Sy/ybar)/(Sx/xbar).

By putting ybar=10xbar, b=10, CVx=0.1 and CVy=0.2.

(xbar/10xbar)10=r(0.2/0.1)

1=r(0.2/0.1)

1=r(2)

r=0.5

There is moderate positive correlation between y and x.
