Answer: a=17 mm length
b=37 mm width
Step-by-step explanation:
P=2a+2b
a -length
b-width
b=2a+3
------------------
108mm=2a+2(2a+3)
108=6a+6
6a=102
a=17 mm
b=17*2+3
b=34+3
b=37 mm
A reasonable function is W = 7F + 5000
Where W is the weight of the plane and F is the number of gallons of fuel.
The domain is the set of possible values for F. That is from 0 (empty tank) to 400 (full tank).
So the domain is F = [0,400], or what is equivalente 0 ≤ F ≤ 400.
The range is the set of values of W.
The minimum value of W is when F = 0 => W = 7(0) + 5000 = 5,000.
The maximum value of W is when F = 400 => W = 7(400) + 5000 = 7,800
So the range is W = [5,000 ; 7,800], pr 5000 ≤ W ≤ 7,800.
Answer:
A. 2.5 standard deviations below the average salary.
Step-by-step explanation:
In a normally distributed sample, the z-score measure how many standard deviations a measure is above or below the mean.
If the zscore is positive, the measure is above the mean.
If it is negative, the measure is below the mean.
A quality control specialist calculated thez-score associated with his own salary and found it was minus2.50. What is his salary?
This means that his salary is 2.5 standard deviations below the mean, that is the average salary.
The correct answer is A.
