Answer:
non-proportional
Step-by-step explanation:
non-proportional because it doesn't pass through the origin.
Using the normal distribution, it is found that 95.65% of full term newborn female infants with a head circumference between 31 cm and 36 cm.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The proportion of full term newborn female infants with a head circumference between 31 cm and 36 cm is the <u>p-value of Z when X = 36 subtracted by the p-value of Z when X = 31</u>, hence:
X = 36:
Z = 1.83
Z = 1.83 has a p-value of 0.9664.
X = 31:
Z = -2.33
Z = -2.33 has a p-value of 0.0099.
0.9664 - 0.0099 = 0.9565.
0.9565 = 95.65% of full term newborn female infants with a head circumference between 31 cm and 36 cm.

Answer:
t = 3 seconds
Step-by-step explanation:
This is a quadratic equation. First set it up and set it equal to 0 (the ground).
-16t² + 46t + 6 = 0
The quadratic formula is (-b ± √(b² - 4ac))/2a
a= -16
b = 46
c = 6
Plug those numbers into the equation and solve which will result in -.125 or 3.
The time of course can not be negative in this case. Therefore, t=3 seconds.
The basic ratio of 12:27 is 4:9. You just divide both numbers by 3.
