Find the distance between the points (7,23) and (3,-3), rounded to the hundredths place

Molodets [167]

Answer:

26.31

Step-by-step explanation:

Use distance formula

d = $\sqrt{(x_{2}-x_{1)^{2} + (y_{2}-y_ ^{1)^2} } }$

substitute in points and solve

d = $\sqrt{(7-3)^2 + (23-(-3))^{2} }$

d = $\sqrt{4^{2}+26^{2} }$

d = $\sqrt{16 + 676}$

d = $\sqrt{692}$

d = 26.30589288

d = 26.31 rounded

28)A regression equation is obtained for a collection of paired data. It is found that the total variation is 24.488, the explai

Doss [256]

Answer: The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

$\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}$

Substituting given values, we get

$\text{coefficient of determination} =\frac{15.405}{24.488}$

$=0.6291$

Therefore, the coefficient of determination = 0.6291
