Inverse of 1.5x+4: 2(x-4) /3
Slope of 1.5x+4: m=1.5
Answer:
Step-by-step explanation:
sample size = n = 60
Sample mean = x bar = 5.25
Sample sd = s = 0.55
Std error of sample = s/sqrt n = 0.071
(One tailed test)
Mean difference = 5.25-5.4 = -0.15
Test statistic t = Mean diff/Se = -2.11
df=59
(since population std dev is not known t test is used)
p value =0.01955
Since p <alpha =0.05 we reject null hypothesis.
The results suggest about the sample group that the sample is from a population with a mean less than 5.4
By applying <em>reflection</em> theory and constructing a <em>geometric</em> system of two <em>proportional right</em> triangles, the height of the stainless steel globe is approximately 140 ft.
<h3>How to estimate the height of the stainless steel globe</h3>
By physics we know that both the angle of incidence and the angle of reflection are same. Thus, we have a <em>geometric</em> system formed by two <em>proportional right</em> triangles:
5.6 ft / 4 ft = h / 100 ft
h = (5.6 ft × 100 ft) / 4ft
h = 140 ft
By applying <em>reflection</em> theory and constructing a <em>geometric</em> system of two <em>proportional right</em> triangles, the height of the stainless steel globe is approximately 140 ft.
