Answer:
84.5
Step-by-step explanation:
Use trig functions to find x. Trig functions are special relationships which exits between the sides of right triangles. Since you need to find x the hypotenuse and you have the adjacent side to 77 degree angle use cosine.
Cos 77 = 19/x
0.22495 = 19/x
19/0.22495 = x
84.5 = x
Answer:
required probability is .3446
Step-by-step explanation:
It is given that most expected time of completion = 90 days
Variance = 25
We know that

Thus the standard normal deviate is given by

Applying values we get

Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446
Thus required probability is .3446
Energía cinética = 1 / 2mv²
Donde m es la masa y v es la velocidad
De la pregunta
la masa es de 16 libras
la velocidad es de 30 m / s
16 libras es equivalente a 7.257 kg
Entonces la energía cinética es
1/2(7.257)(30)²

Answer:
8
Step-by-step explanation:
The 'mean' is the same as the 'average'
( 7 + x + 5 + 3 + 2) / 5 = 5
7+x+5+3+2 = 25
x = 8
