Step-by-step explanation:
---------- (1)
Differentiate equation (1) w.r.t <em>t </em>and equate it to zero (in order to determine maxima)
Substitute this value in equation (1)
Answer:
A = m²
Step-by-step explanation:
Given that a square has a perimeter of (2x - 48),
Each side of the perimeter must be: (because a square has 4 sides)
We need to determine the side of each perimeter:
s =
Factor out 2 from the numerator:
s =
Then, cancel out 2 and 4 from the fraction, leaving 2 in the denominator:
s = ← <em><u>This represents the side of a square</u></em>
Therefore, the area of a square is:
A = side (s)²
A = m²
Answer:
Step-by-step explanation:
a)
b) Sample mean is the average of sample
c) std deviation of the sample
d) std dev/sq rt n
e) (sample mean - mu)/std error
f) p value = prob with test statistic
g) If p < alpha, reject H0.
h) If rejected, there is evidence that significant difference between population mean and sample mean.
