Mean is 0.43 kg.
0.43+0.1+0.1= 0.45
0.45 is two standard deviation above.
All that are below mean is 50%,
Two standard deviation above is 95%/2=47.5%
50%+47.5% =97.7% are balls that are less than 0.45 kg.
100%-97.7%=2.5% balls that are more than 0.45 kg
2.3%=0.025
800*0.025 = 20 <span>soccer balls weigh more than 0.45 kg
Answer is b) 20.</span>
<span>Total lot - house -other side
=(56 ft 9 in) - (34 ft 10 in) - (5 ft 5 in)
=(55 ft 21 in) - (34 ft 10 in) - (5 ft 5 in)
=16 ft 6 in
Convert to inches: </span>16 ft x 12 in/ft)+ 6 in= Total in inches<span>192 in + 6 in= Total in inches
198 in= Total in inches
Check: One side + house + other side = Lot width
(5 ft 5 in)+(34 ft 10 in)+(16 ft 6 in)=Lot width
56 ft 9 in=Lot width, which equals the given.</span>
Answer:
x=0
Step-by-step explanation:
2x+4-6=
We move all terms to the left:

Answer:
slope = 7 and point = (3, 7)
b = y - slope*x
b = 7 -7 * 3
b = -14
Then we enter "b" and the slope into this equation:
y = 7x -14
