If I’m correct use the slope −13 - 1 3 and a given point (−9,2) ( - 9 , 2 ) to substitute for x1 x 1 and y1 y 1 in the point-slope form y−y1=m(x−x1) y - y 1 = m ( x - x 1 ) , which is derived from the slope equation m=y2−y1x2−x1 m = y 2 - y 1 x 2 - x 1 .

Given P(A)=0.78P(A)=0.78, P(B)=0.65P(B)=0.65 and P(A\cup B)=0.873P(A∪B)=0.873, find the value of P(A\cap B)P(A∩B), rounding to t

Answer:

$P(A\ n\ B) = 0.557$

Step-by-step explanation:

Given

$P(A) = 0.78$

$P(B) = 0.65$

$P(A\ u\ B) = 0.873$

Required

Determine $P(A\ n\ B)$

From laws of probability, we have:

$P(A\ n\ B) = P(A) + P(B) - P(A\ u\ B)$

Substitute in values

$P(A\ n\ B) = 0.78 + 0.65 - 0.873$

$P(A\ n\ B) = 0.557$

Hence, $P(A\ n\ B)$ <em> is calculated to be 0.557</em>

Suppose y varies directly with x. If y = 6 when x = 2, find x when y = 12.

igomit [66]

Answer:

x = 4 when y = 12

Step-by-step explanation:

The ratio of y to x is 6:2. If you multiply either one of them, you must do the same to the remaining number. So, when you multiply 6 by 2 to get 12, you must also multiply 2 by 2 to keep the ratio equal and the same. 2x2 = 4, so x=4 when y=12. Hope this helped! Good luck with other math problems :)
