What is the Y intercept in the equation Y equals 45X +65?

VashaNatasha [74]

The typical form of the slope intercept equation would be:

Y = mX + B

Where b is the y intercept, thus in thus case the y intercept would be 65 = (0,65).

The following table shows the probability of rolling the numbers 1 through 7

Marysya12 [62]

Answer:

2.0

Step-by-step explanation:

Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die

The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)

The first moment (AKA the average is..)

$\frac{1+2+3+4+5+6+7}{7}=4$

The second moment is..

$\frac{1^2+2^2+3^2+4^2+5^2+6^2+7^2}{7}=20$

$\sqrt{20-4^2}=2$

Let f(x)=4x and g(x)=(4)x−1+2 . Which transformations are needed to transform the graph of f(x) to the graph of g(x) ? Select ea

Inessa05 [86]

Answer:

horizontal translation 1 unit right and vertical translation 2 unit up

Step-by-step explanation:

we are given

$f(x)=4^x$

$g(x)=4^{x-1}+2$

We can see that in place x , we have x-1

So, it is shifted horizontally right side by 1 unit

We have +2 added to f(x)-value

It means 2 is added to y-value

So, it is shifted vertically upward by 2 units

So, horizontal translation 1 unit right and vertical translation 2 unit up
