Answer: 0.23

Step-by-step explanation:

Given : F is the event "works in the finishing department;"

and A is the event "is absent excessively."

Given : 10% of all plant employees work in the finishing department; 20% of all plant employees are absent excessively; and 7% of all plant employees work in the finishing department and are absent excessively.

i.e. P(A)= 0.20 ; P(F)=0.10 ; P(A ∩ F) = 0.07

We know that $P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)$

Then,

$P(A\cup F)=P(A)+P(F)-P(A\cap F)\\\\\Rightarrow\ P(A\cup F)=0.20+0.10-0.07=0.23$

Hence, the required answer is $P(A\cup F)=0.23$

Find the measure of the exterior angle.

miss Akunina [59]

Answer:

120 degrees! (line) or 300.

Step-by-step explanation:

All lines are 180 degrees, this triangle is congruent, so all sides are 60 degrees. 180 minus 60 is 120.

If it's a measure of a 360 degree angle, using 2 lines from the triangle, then you take 60 away from 360. A circle formed with that angle at it's radius would be 300 degrees.

Find the midpoint of R(2,2) and S(-3,6)

musickatia [10]

Answer: (-0.5, 4)

Step-by-step explanation:

Midpoint formula: $(\frac{x1+x2}{2} ,\frac{y1+y2}{2} )$

(x1, x2)=(2, -3)

(y1, y2)=(2, 6)

-----------------------------------------------

$(\frac{x1+x2}{2} ,\frac{y1+y2}{2} )$

= $(\frac{2-3}{2} ,\frac{2+6}{2} )$

= $(\frac{-1}{2} ,\frac{8}{2} )$

= $(-0.5, 4)$

Hope this helps!! :)
