Answer:
The units of measurement for the composite function c(w(h)) is canvases over weeks.
Step-by-step explanation:
Given :
The function c(t) approximates how many canvases she paints per hour.
The function w(h) represents how many hours per week Christina spends painting the canvases.
To Find: What are the units of measurement for the composite function c(w(h))?
Solution:
C(t)= canvases paints per hour
W(h)=hours per week
C(w(h)) =canvases paints per hour * hours per week
C(w(h)) =canvases per week
So, Option 3 is true
Hence , the units of measurement for the composite function c(w(h)) is canvases over weeks.
Answer:
The middle 99.7% of Twinkies weigh between approximately 1.2 and 1.8 ounces.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 1.5
Standard deviation = 0.1
middle 99.7%
Within 3 standard deviations of the mean, so
1.5 - 3*0.1 = 1.2
1.5 + 3*0.1 = 1.8
So the answer is:
The middle 99.7% of Twinkies weigh between approximately 1.2 and 1.8 ounces.
The answer to your problem is 69
