0.22 because one side is 11 and the other is 11 so 11+11 is 22 the pursent of 22 is 0.22
Answer:
A.) JH = 1 in
B.) GH = 3/4 in
C.) m∠F = 62°
D.) m∠J = 118°
Step-by-step explanation:
In a parallelogram, opposite angles are congruent, adjacent angles are supplementary, and opposite sides are congruent.
A.) JH = FG = 1 in
B.) GH = FJ = 3/4 in
C.) m∠F = m∠H = 62°
D.) m∠J = m∠G = 180° -62° = 118°
Answer:
a) 33.33%)
b) 135 minutes
c) 8.66 min
d) 50%
Step-by-step explanation:
a) the probability for a uniform distribution is
P(b<X<a) = (a-b)/(c-d) , where c and d are the maximum and minimum values
therefore the probability that the flight is more than 140 minutes ( and less than 150 since it is the maximum value)
P(140<X<150) = (a-b)/(c-d) = (150-140)/(150-120) = 10/30 = 1/3 (33.33%)
b) the mean (expected value) for a uniform probability distribution is
E(X) = (c+d)/2 = (120+150)/2 = 135 minutes
c) the standard deviation for a uniform probability distribution is
σ²(X)= (c-d)²/12 = (150-120)²/12 = 75 min²
σ = √75 min² = 8.66 min
b) following the same procedure as in a)
P(120<X<135) = (a-b)/(c-d) = (135-120)/(150-120) = 15/30 = 1/2 (50%)
Answer:
X = 48
Step-by-step explanation:
When you type sin(42) in your calculator it will give you something around 0.669.
If you try reverse sinus sin-1(0.669) it will give you 42.
Therefore you can say that:
Cos(x) = 0.669
So you can reverse the cos to get your answer
Cos-1(0.669) = 48
Or
Cos-1 (sin(42))
Total = 16
Graduates = 4
Rounding off to 2 decimal places,
Answer is 0.06
