Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle

sin17° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{AC}{42}$ ( multiply both sides by 42 )

42 × sin17° = AC then

AC ≈ 12.28 ( to 2 dec.places ) → B

2x + y =8 and 4x -2y = 6

irakobra [83]

Answer:

x=1.25 and y=-5.5

Step-by-step explanation:

2x+y=-8, 2x=-y-8 or 4x=-2y-16. Plug this value in the second equation, we have - 2y-16-2y=6, y=-5.5. Plugging this in any equation we have, x=1.25

Is the data point, P, an outlier, an influential point, both, or neither?

NikAS [45]

Answer:

<h3>Option a) Influential point is correct.</h3><h3>∴ the point P(194,364.2) is an influential point.</h3>

Step-by-step explanation:

Given that the regression equation for a set of paired data is = -23.8 + 2x. The values of x run from 100 to 400.

A new data point, P(194, 364.2), is added to the set.

From the given we can write it as y = -23.8+2x

Put x=194 in the above equation we get,

$y(194) = -23.8+2\times 194$

$=-23.8+ 388$

= 364.2

Hence, point P(194,364.2) is on regression line and it is not outlier.

<h3> ∴ the point P(194,364.2) is an influential point.</h3><h3>Hence option a) Influential point is correct.</h3>
