Answer:
The 10% condition would not apply here
Explanation:
The 10% condition is the recommended size of sample from the population to get a non biased result. The 10% condition requires that the sample be not more than 10% of the population.
Tossing a coin is an example of a Bernoulli trial. A Bernoulli trial is one that has two possible outcomes, this face of the coin or the other face of the coin. The 10% condition does not apply to Bernoulli trials that are independent events.
Therefore the 10% condition would not apply here because tossing a coin is an an independent event. An independent event is one with replacement.
35
since m and n are the midpoints of ab and ac resistively
then ,bc=2mn=16
since m and l are the midpoints of ba and bc respectively
then, ac =2mn =10
then,nc =1/2 × 10 =5
similary, mb=6
then ,perimeter=nc+mb+mn+bc=5+6+8+16=35
Since a pentagon has 5 sides, you would divide the perimeter by the number of sides.
641.5/5 = 128.3cm
Therefore, the length of one side of the pentagon is 128.3cm.
Answer:
Not to sure if this is correct but I think it is 6: 1 : 18
pls msg me if you need explanation
Answer:
![\sin \theta=-\frac{4}{5}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%3D-%5Cfrac%7B4%7D%7B5%7D)
Step-by-step explanation:
Given:
Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).
So, the 'x' value is 3 and 'y' value id -4.
Using Pythagoras Theorem, we find the hypotenuse.
Hypotenuse = ![\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5](https://tex.z-dn.net/?f=%5Csqrt%7B3%5E2%2B%28-4%29%5E2%7D%3D%5Csqrt%7B9%2B16%7D%3D%5Csqrt%7B25%7D%3D5)
Now, using the sine ratio for the angle, we have
![\sin \theta=\frac{Opposite}{Hypotenuse}\\\sin \theta=\frac{-4}{5}\\\sin \theta=-\frac{4}{5}](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%3D%5Cfrac%7BOpposite%7D%7BHypotenuse%7D%5C%5C%5Csin%20%5Ctheta%3D%5Cfrac%7B-4%7D%7B5%7D%5C%5C%5Csin%20%5Ctheta%3D-%5Cfrac%7B4%7D%7B5%7D)
Therefore, the value of
is
.
The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,
