Answer:
0.5987
Step-by-step explanation:
We are supposed to find the probability that if a person is randomly selected, his weight will be greater than 160 pounds.
Formula :
P(x>160)
Substitute the values in the formula :
Refer the z table for p value
p value = 0.4013
P(x>160)= 1-P(x<160)=1-0.4013=0.5987
Hence the probability that if a person is randomly selected, his weight will be greater than 160 pounds is 0.5987
The ratios are: sin B = 4/5 , cos B = 3/5 and tan B = 4/3
Step-by-step explanation:
We can see in the diagram that the values of all sides are given. In case of trigonometric ratios, the side in front of angle under consideration is perpendicular and the side adjacent to angle is base.
In the given case, we have to find trigonometric ratios for angle B; So,
Base = a = 3
Perpendicular = b = 4
Hypotenuse = c = 5
Hence,
The ratios will be:
The ratios are: sin B = 4/5 , cos B = 3/5 and tan B = 4/3
