Answer:
See below
Step-by-step explanation:
625 = 25^2, or (5^2)^2 = 5^4
Step-by-step explanation:
First calculate the z-score.
z = (x − μ) / σ
z = (11.07 − 11.5) / 2.7
z ≈ -0.16
From a z-score table:
P(z<-0.16) = 0.4364
The proportion of babies that weigh less than 11.07 lbs is 0.4364.
Answer:
a(n) = 9.5 + 2(n - 1)
Step-by-step explanation:
Observe that each new term is obtained by adding 2 to the previous term. Thus, the common difference is 2 and the first term is 9.5.
Then a(n) = 9.5 + 2(n - 1)
To find the time to reach the maximum height you can subtract the constant 6 and write the function as:
h'(t) = -16t^2 + 50t
Then factor it: h'(t) = -2t(8t-25)
Then find the two roots:
t =0 and
8t - 25 = 0 ⇒ t = 25/8 = 3.125
The vertex is in the half between 0 and 3.125, i.e. [0+3.125]/2 = 1.5625
Then the time searched is approximately 1.56 seconds.
15 weeks is your answer, I debating between 13, and 15, so if 15 is incorrect go with the 13
