Answer:
Step-by-step explanation:
Given that the random variable X is normally distributed, with
mean = 50 and standard deviation = 7.
Then we have z=
Using this and normal table we find that
a)
b) When z=0.02
we get
c) 90th percentile z value =1.645
90th percentile of X
Answer:
8.16666667 square inches
Step-by-step explanation:
36.75/4.5=l
length=8.16666667
Answer:
Step-by-step explanation:
a.)
<A = 90 - 67 = <u>23</u>* A = (a^2 + 14.72^2 = 16^2) = a = <u>6.25</u>
<B = 67* B = (sin67 = b/16) = sin67*16 = <u>14.73</u>
<C = 90* C = 16
b.)
a = (a^2 + 2^2 = 6^2) = a = <u>5. 66</u> <A = (cosA = 2/6) = <u>70.53*</u>
b = 2 <B = 90-70.53 = <u>19.47*</u>
c = 6 <C = 90*
Answer:
2.83°
Step-by-step explanation:
The tangent of an angle is the ratio of rise to run.
θ = arctan(5/101) ≈ 2.83°
_____
We assume the length is referring to the horizontal distance.
If it is the distance along the path, then the angle is ...
θ = arcsin(5/101) ≈ 2.84°
