there is nothing
Step-by-step explanation:
<span>Assuming that the string of the kite does not sag. It then serves as the hypotenuse of the right triangle. The horizontal distance is the length of the base of the triangle. The horizontal distance can the be calculated using trigonometry: h = 50 cos(56 deg) = 28.0 ft.

Answer:
The smallest value of n that satisfies the requirements for a normally distributed p is 30
Step-by-step explanation:
The Central Limit Theorem says that if we have a random sample and the sample size is large enough (usually bigger than 30), then the sample proportion will follow a normal distribution with mean p, where p is the true population proportion.
Answer:
I. B. true
II. A true
Step-by-step explanation:
we can use the quadratic equation:
we have:
1)
a=1 b=-4 c=5
the quadratic expression has two complex factors.
2)
a=1 b=-5 c=14
the solution of are
3)
a=2 b=-8 c=5
Step-by-step explanation:
a) 2z+3z+4z=180
9z=180
z=20
So,three angles are 40,60 and 80
b) (y+30)+(2y+80)+(y+10)=180
y+30+2y+80+y+10=180
4y+120=180
4y=60
y=15
Three angles are 45,110,25
