Answer:
Step-by-step explanation:
The firm tests 75 parts, and finds that 0.25 of them are notusable
n = 75
x = 0.25 \times 75 = 18.75≈19
Confidence level = 95%
So, Z_\alpha at 95% = 1.96
Formula of confidence interval of one sample proportion:
Confidence interval

To do this we first have to find the unit rate of 2,600.
2,600/4=650 each week. Then, we just multiply 650x20, with 20 being the number of weeks.
650x20=13,000<---Answer

Answer: the hat= $30. The equation you would use to solve is 2s+h=50
Step-by-step explanation:
2s+h=50
2(10)+h=50
20+h=50
-20. -20
h=30
interior angle of n-gon formula: 180 - ( 360 / n)
a 30 sided polygon, so in this case n = 30
so
interior angle = 180 - ( 360 / 30)
interior angle = 180 - 12
interior angle = 168
answer
168 degrees
Answer:
cos(x)=0.6
Step-by-step explanation:
cos(x) represents the horizontal distance of the unit vector
sin(x) represents the vertical distance of the unit vector (0.8)
tan(x) represents the distance on the tangent line from the point to the x-axis
cot(x) represents the distance on the tangent line from the point to the y=axis
