Which is correct to find the value of the coefficient of determination (r2)?

1 answer:

4 0

The coefficient of determination is presented by R² is mostly used in the analysis of regression where it is the proportion of the variance in the dependent variable that is predictable from the independent variable. The range of values between the predicted scores and the actual scores is between 0 to 1. The closer the value to 1, the greater is the relationship between variables and has lesser errors. For example, if there is an R² of 0.80, then it means that 80% is predictable. R² can be obtained using excel as trendline or with the use of formula.

Given the point (3,4) the slope of 6, find y, when x=27

vitfil [10]

Answer:

y = 148

Step-by-step explanation:

First, we use the point-slope form of the equation of a line to find the equation of this line.

y - y1 = m(x - x1)

y - 4 = 6(x - 3)

y - 4 = 6x - 18

y = 6x - 14

Now we let x = 27 and find y.

y = 6(27) - 14

y = 162 - 14

y = 148

I’m sorry but need help

arsen [322]

These are pretty easy once you get the concept.

think of random letter (x) as the term y, so in the case of p(x)=-3+4x, its just asking what is y when x equals all those values.

so p(-2) = -3 + 4(-2), since its asking to plug in -2 for x, which equals -11

p(0) = -3 + 4(0)

= -3

p(5) = -3 + 4(5)

= 17

On May 17th Jane took out a loan for $33,000 at 6% to open her law practice office the loan will mature the following year on Ja

frosja888 [35]

Answer:

$ 31050

Step-by-step explanation:

Step 1 : Write the formula for calculating simple interest.

Simple Interest = P x R x T

100

P: Principal Amount-The loan taken (30,000)

R: Interest rate at which the loan is give (6)

T: Time period of the loan in years-there are 12 months in 1 year. There are 7 months from May till June (7/12)

Step 2: Substitute values in the formula

Simple Interest = 30,000 x 6 x 7/12

100

Simple Interest = $1050

Step 3: Calculate the amount due at maturity

At the maturity or the end of the time period given, the original or principal amount of the loan has to be repaid along with the simple interest.

Amount at maturity = Principal Amount + Simple Interet

Amount at maturity = 30,000 + 1050

Amount at maturity = $31050
