Answer:
Step-by-step explanation:
406.0 gram setting.
N= 40 bag sample had a
mean of 405.0 grams.
A level of significance of 0.02
the standard deviation is known to be 26.0
mean = Np = 40 * 0.02 =
Z = (variate - mean)/standard deviation
Z = 406 - 405)/26 = 0.038
Answer:
The weight of each circle is 2g
180degree should be the value of B
If the pond were a rectangle, then:
length=15 m
width=6 m
We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)
Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m
We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.
