V(t) = 32t
when t = 3 seconds,
V = 32*3
V = 96
So velocity will be 96 units/s after 3 seconds.
Answer:
En la vida cotidiana, el conocimiento sobre el cálculo de perímetro nos puede ser útil al momento de conocer una longitud total. El perímetro de una figura corresponde a la suma de la longitud de los lados que la conforman.
Answer:
(A) P (D > 0) = 99.38%
(B) P (D > 15) = 10.56%
Step-by-step explanation:
The random variable D = difference, is defined as the difference between the reading test scores after and before the program.
The random variable <em>D </em>follows a normal distribution with mean, and standard deviation, .
(A)
Compute the probability that the children showed any improvement, i.e.
P (D > 0):
Use the standard normal random variable to determine the probability.
The percentage of children showed any improvement is:
0.9938 × 100 = 99.38%
Thus, 99.38% of children showed improvement.
(B)
Compute the probability that the children improved by more than 15 points, i.e. P (D > 15):
Use the standard normal random variable to determine the probability.
The percentage of children improved by more than 15 points is:
0.1056 × 100 = 10.56%
Thus, 10.56% of children showed improvement by more than 15 points.
