write down the answers you already have done.
Answer:
P(Male = 2) = 63.9%
Step-by-step explanation:
40000C2 / 50000C2
[(40000 * 39999) / (1*2)] / [(50000 * 49999 *) / (1*2)]
3,199,920,000 / 4,999,900,000
0.6399996799935999
P(Male = 2) = 63.9%
X^2 - 6x = 20
x^2 - 6x + 9 = 20 + 9
(x - 3)^2 = 29
x - 3 = (+-) sqrt 29
x = 3 (+-) sqrt 29
x = 3 (+-) 5.39
x = 3 + 5.39 = 8.39 <=
x = 3 - 5.39 = - 2.39 <=
Answer:
(a) 
(b) 
(c) 
Step-by-step explanation:
(a) when t = 44sec
s(44) ≅ 
(b) How fast the hammer is traveling i.e. the speed of the hammer.
To find speed, we differentiate the distance s(t) with respect to time, t
at t = 44sec,
≅ 
(c) The hammer's acceleration can be obtained by differentiating the speed v(t) with respect to time, t
There's no need to substitute t = 44sec because the acceleration is independent of time.
There are 2 before the decimal point because 3×4=12 and 12 has two digits.
There are 3 after the decimal point because we add together the number of digits after the decimal point in the operands, which is 1 plus 2=3. In all then there are 2+3=5 significant figures.
