For this exponential function,
1 answer:
Output value (y) of the y = 1.157.exponetial functio9n when x = 3 is: (3, 1,250).
<h3>What is an Exponential Function?</h3>An exponential function is a type of function that has a constant that is raised to a given power. It is expressed as .
Given the exponential function,
When x = 3, thus:
Therefore, output value (y) of the y = 1.157.exponetial function when x = 3 is: (3, 1,250).

Answer:
Required Probability = 0.1283 .
Step-by-step explanation:
We are given that at Meadow brook Hospital, the mean weight of babies born to full-term pregnancies is 7 lbs with a standard deviation of 14 oz.
Firstly, standard deviation in lbs = 14 ÷ 16 = 0.875 lbs.
Also, Birth weights of babies born to full-term pregnancies follow roughly a Normal distribution.
Let X = mean weight of the babies, so X ~ N()
The standard normal z distribution is given by;
Z = ~ N(0,1)
where, X bar = sample mean weight
n = sample size = 4
Now, probability that the average weight of the four babies will be more than 7.5 lbs = P(X bar > 7.5 lbs)
P(X bar > 7.5) = P( >
) = P(Z > 1.1428) = 0.1283 (using z% table)
Therefore, the probability that the average weight of the four babies will be more than 7.5 lbs is 0.1283 .
