Sine of the angle is opposite over hypotenuse, so:
Opp/hyp = sin32 degrees
Hyp = opp/sin32 = 20.8. True
Answer:
No
Step-by-step explanation:
<u>Explanation</u>:-
- The graph of the normal distribution y = f(x) in the x y- plane is known as normal curve.The curve is bell shaped and symmetrical about the line x = μ
So The first statement is not true because symmetrical about the line x = μ not 'm'
- Area under normal curve represents the total population
so the total area under the curve is 100 or one so The second statement is true
- The normal distribution for mean is zero and standard deviation is one is known as standard normal distribution.
- 95 percentage within two standard deviations
- 99.7 percentage of the data are within three standard deviations of the mean.
- 68 percentage of the data are within one standard deviation
All above points are true so In given data the third statement is not true
95 percentage within two standard deviations not one
- The fourth statement is false because 68 percentage of the data are within one standard deviation not 34 percentage.
- All data sets are normally distributed its depend on given data
Answer:
30%
Step-by-step explanation:
(50 - 35)/50 x 100 = (15/50) x 100 = 30%
Answer: -2 i believe because if you take and subtract one from 8 you should get 9
