Answer:
LM = 20
Step-by-step explanation:
Use the Sine rule to calculate the length of LM
We require to find ∠N using sum of angles in a triangle.
∠N = 180° - (53 + 44)° = 180° - 97° = 83°, then
= ( cross- m ultiply )
LM × sin44° = LN × sin83°, that is
LM × sin44° = 14 × sin83° ( divide both sides by sin44° )
LM = = 20
Answer:
So the answer for this case would be n=16 rounded up to the nearest integer
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the margin of error desired
The margin of error for the true mean is given by this formula:
(a)
And on this case we have that ME =0.03 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence level is 80%, the significance would be and the critical value for this case is , replacing into formula (b) we got:
So the answer for this case would be n=16 rounded up to the nearest integer
Answer: F
Step-by-step explanation:
We know the angle is in the first quadrant, so its argument is in between 0 and 90 degrees.
Also, its modulus is the distance from the origin, which in this case is
The answer that best matches this is F
