(not sure )
my method
let projection of b onto line dq be M
BM is 2r
then let the remaining angle ( right) be K
in triangle BMK ,
MK = 29-5-r
By Pyth. theorem ,
23^2 = (2r)^2+(29-5-r)^2
529=4r^2+576-48r+r^2
5r^2-48r+47=0
r = 8.493237063 or 1.106762937(rejected)
You need to turn 1/2 to .5 and 3/4 to .75 then you use this equation.
75% * 950,000 (profit)
+ 25% * -285,000 (loss)
<span>= then you subtract the numbers from the separate </span>
<span>= answer --> expected profit from the second mall</span>
Answer:
3/7.
Step-by-step explanation:
The total number of ways to pick 4 out of 8 = 8C4
= 8!/ 4!4!
= 70 ways.
The number of ways when 2 are women = 5C2 * 3
= 10 * 3
= 30.
So the required probability = 30/70
= 3/7.

Answer:
Step-by-step explanation:
<u>Let the score is x. The average is:</u>
- (83 + 56 + 94 + x)/4 = 82
- x + 233 = 4*82
- x = 328 - 233
- x = 95
