Answer:
1.67
Step-by-step explanation:
you should do 15 ÷ 9 and you get 1.6666666667 and when you simplify that you get 1.67
I believe the equation should be y = -0.5sin(x-2<span>π)-2</span>
Answer:
34%
Step-by-step explanation:
Given that the distribution of daily light bulb request replacement is approximately bell shaped with ;
Mean , μ = 45 ; standard deviation, σ = 3
Using the empirical formula where ;
68% of the distribution is within 1 standard deviation from the mean ;
95% of the distribution is within 2 standard deviation from the mean
Lightbulb replacement numbering between ;
42 and 45
Number of standard deviations from the mean /
Z = (x - μ) / σ
(x - μ) / σ < Z < (x - μ) / σ
(42 - 45) / 3 = -1
This lies between - 1 standard deviation a d the mean :
Hence, the approximate percentage is : 68% / 2 = 34%
Answer:
reflex angle
Step-by-step explanation:
Acute is less than 90
Right = 90
Obtuse is greater than 90 and less than 180
Straight is 180
Reflex is greater than 180 and less than 360
This is greater than 90 and less than 180 so it is a reflex angle
