If human development really does proceed continuously, what value does stage theories of development have?
Answer:
Even if human development is continuous, there is some value in stage theories of development. A stage theory of development allows experts to examine the developmental progress of individuals and establish a basis for developmental changes. This can help identify developmental issues earlier. Stage theories can also help researchers who are examining physical development examine discrete changes in the brain that allow certain developmental milestones to be reached. Finally, stage theories can give one a sense of where an individual is developmentally, and can prepare the person for changes that may occur during their lifetime.
Answer:
A) 1000 different selections
B) probability of winning = 0.001
C) Net profit on winning = $257.20
D) E(y) = -0. 89165
E) Option B - The Pick 4 game is a better bet because it has a larger expected value.
Step-by-step explanation:
A) For the different selections possible, since each of the digits from 0 - 9 can take a total of 10 digits, then the different selections possible will be = 10³ = 1000 different selections
B) To find the probability of winning, since only one pick can be a winning one. Thus probability of winning = 1/1000 = 0.001
C) Net profit on winning = Amount won - Amount staked
Amount won = $258.35
Amount staked = $1.15
Thus;
Net profit on winning = $258.35 - $1.15
Net profit on winning = $257.20
D) If we call the net profit "y", then Expected value is:
E(y) = 257.2(0.001) - 1.15(1 - 0.001)
E(y) = 0.2572 - 1.14885
E(y) = -0. 89165
E) We are told that:If you bet $ 1.15 in a certain state's Pick 4 game, the expected value is negative −$0.89
The expected value of -0.89 in pick 4 is better than that in pick 3 because it's larger.
The distance travelled is 10 m
The velocity gained at the end of the time is 2 m/s
<h3>Motion</h3>
From the question, we are to determine distance travelled and the velocity gained
From one of the equations of motion for <u>linear motion</u>, we have that
S = ut + 1/2at²
Where S is the distance
u is the initial velocity
t is the time taken
and a is the acceleration
First, we will calculate the acceleration
Using the formula,
F = ma
Where F is the force
m is the mass
and a is the acceleration
∴ a = F/m
Where F is the force
and a is the acceleration
From the given information,
F = 50 N
m = 250 kg
Putting the parameters into the equation,
a = 50/250
a = 0.2 m/s²
Thus,
From the information,
u = 0 m/s (Since the object was initially at rest)
t = 10 s
S = 0(t) + 1/2(0.2)(10)²
S = 10 m
Hence, the distance travelled is 10 m
For the velocity
Using the formula,
v = u + at
Where v is the velocity
v = 0 + 0.2×10
v = 2 m/s
Hence, the velocity gained at the end of the time is 2 m/s

Answer:
The last one
Step-by-step explanation:
-4 1/3 is less than -1 3/4 because its farther on the negative side and -1 3/4 is closer to the positive side
