Answer:
∴ ∠BAD = 
(0.2044) = 11.8°
Step-by-step explanation:
i) AD = 9 cm
ii) DC = 3 cm
iii) ∠BCD = 35°
iv) Since AB is parallel to DC and ∠ABD = 90° then we can conclude that ∠BDC = 90°.
v) 
= 0.6128 ∴ BD = 3 
0.6128 = 1.84 cm
vi) ∴ sin(∠ BAD ) = 
⇒ sin(∠ BAD ) = 
= 0.2044
∴ ∠BAD = (0.2044) = 11.8°
4x1/2=2. 2 is less than 4 so it shows that it is false.
Answer:
x and y = 0
the question looks weird and almost wrong because when you subtract the equations, you are left with nothing
Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
Answer:
P(C4) = 0.0711
Step-by-step explanation:
consider the first draw = 15/23 since it cannot be a blue ball
The second draw = 21/29 since 6 more red balls will be added after the draw since a blue ball cannot be drawn
the third draw = 27/35 since 6 more red balls will be added after each draw since a blue ball cannot be drawn
therefore the total number of red balls will be = 15 + 6 + 6 + 6 = 33 red balls after the 4th draw. the total ball now in the urn= 33 red + 4 blue = 41
Hence the probability of drawing a blue ball at the fourth draw after drawing red balls at the previous attempts = 8/41
P(C4) = P ( fourth ball is blue ) * P( first ball red)*P(second ball red) *P(third ball red )
= (8/41) * (15/23) * (21/29)* (27/35) = 0.0711
Answer:
22.3333333
Step-by-step explanation:
Mean = the sum of all of the numbers divided by the amount of numbers given. The sum (134) was divided by the number of numbers (6) to get 22.3333333. This is not 22 and 3 repeating, since my calculator would've rounded the last digit to 4.
