Find the distance between points (2, 9) and (5, 4) to the nearest tenth

Troyanec [42]

Answer:

$Distance = 5.8$

Step-by-step explanation:

$d=\sqrt{(4-9)^{2} } { (5-2)} ^{2} \\$

$d = -5^{2} + 3^{2}$

$d= 25 + 9$

$d= \sqrt{34}$

$distance = 5.8$

Triangle X Y Z is shown. The length of side X Y is (9 n + 12) feet and the length of side X Z is (15 n minus 6) feet. Angles X Y

zmey [24]

Answer:

$n = 3$

$XY = 39$

$XZ = 39$

Step-by-step explanation:

Given

$XY = 9n + 12$

$XZ = 15n - 6$

Solving (a): n

To solve for n;

We make use of

$XY = XZ$

Substitute values for XY and XZ

$9n + 12 = 15n - 6$

$9n - 15n = -12 - 6$

$-6n = -18$

Divide through by -6

$n = 3$

Solving (b) XY

$XY = 9n + 12$

Substitute 3 for n

$XY = 9 * 3 + 12$

$XY = 27 + 12$

$XY = 39$

Solving (c): XZ

$XZ = XY$

$XZ = 39$

Which of the following statements about the Lasso are true with respect to the OLS estimates?

mash [69]

Answer:

B and C

Step-by-step explanation:

B - The purpose of LASSO is to shrink parameter estimates towards zero, lasso shrinkage causes the estimates of the non-zero coefficients to be biased towards zero.

C- Lasso shrinks more accurately than the ridge. In the case of multiple coefficients Lasso selects only some some features and reduces the coefficients of the others to zero. This is called feature selection and it's not a possible in the ridge.
