Answer: 0.6827
Step-by-step explanation:
Given : The resistance of a strain gauge is normally distributed .
Population mean :
Standard deviation :
Let x be the random variable that represents the resistance of a strain gauge is normally distributed .
z-score :
To meet the specification, the resistance must be within the range 100±0.7 ohms i.e. (99.3,100.7).
For x = 100.7
For x = 99.3
By using the standard normal distribution table, The proportion of gauges is acceptable is given by:-
Hence, the proportion of gauges is acceptable=0.6827
4/5 divided by 1/8
= 4/5 x 8/1
32/5

Answer: 27°
Step-by-step explanation:
The easiest way to find the measure of angle Z is to know that <em>in a rhombus, the diagonals are perpendicular bisectors of each other. </em>This means that all the four angles in the center are 90°.
Since we know that all angles in a triangle add up to 180°, we can set the sum of z, 63, and 90 to be 180 and solve for z.
Hence, z is 27°.
