Answer:

x = 0

y = -2

Step-by-step explanation:

2304.06 is written in expanded form

4 is unit place. So, 4 *10⁰ = 4 * 1 = 1 {Any integer to the power of 0 is 1}

x = 0

6 is hundredth place = 6 * 1/100 = 6*10⁻²

y= -2

Evaluate r=5

Salsk061 [2.6K]

Answer:

$\sum (r+1)^2 = 90$

Step-by-step explanation:

Given

$\sum (r+1)^2; r = 1,2....5$

Required

Evaluate

$\sum (r+1)^2; r = 1,2....5$ is equivalent to :

$(1 + 1)^2 +(2 + 1)^2 +(3 + 1)^2 +(4 + 1)^2 +(5 + 1)^2$

$(2)^2 +(3)^2 +(4)^2 +(5)^2 +(6)^2$

$4 + 9 + 16 + 25 + 36$

$90$

Hence:

$\sum (r+1)^2 = 90$

Suppose the correlation coefficient between a predictor variable (a person’s height, measured in centimeters) and a response var

grigory [225]

Answer:

a) The new correlation coefficient should be the same: R = 0.72

Step-by-step explanation:

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.

It is a relative dimensionless measure, so it does not depend on the units of measurement of the variables involved.

If the variables are correlated in centimeters and kilograms, they will also be correlated in inches and pounds, and with the same relative magnitude.

So the answer is

a) The new correlation coefficient should be the same: R = 0.72
