105/2^9
Step-by-step explanation:
The probability of getting a head in a single toss
p=12
The probability of not getting a head in a single toss
q=1−12=12
Now, using Binomial theorem of probability,
The probability of getting exactly r=4 heads in total n=10 tosses
=10C4(1/2)4(1/2)10−4
=10×9×8×7/4! 1/2^4 1/2^6
=2^44⋅9⋅35/24(2^10)
=105/2^9
Answer:
Step-by-step explanation:
Answer:
the scale factor is the vertical expansion factor.
Step-by-step explanation:
The scale factor of 2 in
g(x) = 2·F(x)
means g(x) is a <em>vertical expansion</em> (not shrink) of F(x) — by a factor of 2.
_____
<em>Additional comment</em>
The equation g(x) could be considered to be ...
g(x) = F(x·√2)
in which case g(x) could be interpreted as a <em>horizontal shrink</em> by a factor of (√2)/2. Squeezing a parabola horizontally has the same effect on its appearance as stretching it vertically.
Answer:
Step-by-step explanation:
x = time
y = elevation
At x = 0 , y = 0
It takes the submarine 2 hours to make descent of 2100 ft
=> x = 2 , y = - 2100
Slope = ( -2100 - 0)/(2 - 0) = -1050
y - 0 = -1050 ( x -0)
=> y = -1050x
1050x + y = 0
represent the relationship between the submarine's elevation and time.
